 Today my topic in post-quantity is about dynamic solution. So, dynamic solution, we have a fine solution in complete danger, must be developed with the prime aim of its optimum function of the danger and with the least amount of trauma to the supportive tissues. And all dangers moving function and our aim in the construction of complete dangers be to reduce this moment to minimum and then forces act on a body and no motion results then it is said to be balanced. So, our activity aims to provide stability in complete danger. Occlusion. Occlusion. Occlusion, it is defined as a static contact between insizing and elasticate the surface of an axillary and man-developed. At articulation, it is defined as the dynamic contact relationship between the insizing or contacting surface of the deep during function. Occlusion is the static contact relationship between man-developed and man-developed by dynamic, the articulation is the dynamic contact relationship between opposite surface of deep during function. Excursive moment. The moment occurring to the mandible when the moment occurring within the occlusion when the mandible moves away from the axillary introspecial position. This is called as the excursive moment and balancing side or non-working side. Here we have to understand that when mandible moves to one side then the side to which which moves to the median line is called as the balancing side. When mandible moves to one side, the side to which mandible moves is called as the working side and the side which moves towards the median line is called as the balancing side. Then comes the balance occlusion. This is the bilateral simultaneous anterior and posterior contact relationship between maxillary and man-developed in centric and centric positions to as to limit or lessen the tipping of danger during function. This is given in GPT-8 and then comes the centric occlusion. Here the occlusion of opposing deep when the mandible is in centric relation. This states that the occlusion there is occlusion of the opposing deep when the mandible is in centric relation. This may or may not coincide with the maxillary introspecial position. Again, we have to understand centric relation is a bond-to-bond relation whereas centric occlusion is a truth-to-truth relation. Centric relation can be defined as the maxillomandibular relationship in which condense articulated with the thinness of asphaloportion of their respective distances. This in the most superior and posterior positions and position and this is a clinically designable position and this is independent of the maximum introspecial position and this is a bond-to-bond relation while centric occlusion is a truth-to-truth relation. Accentric occlusion is a request to conduct a deep which occurs during moment of the mandible at centric moments of the mandible and it is of two types. These are two types that is functional occlusion and non-functional occlusion and then comes the functional occlusion. Functional occlusion is also called as working side occlusion. It refers to the tooth-conduct occurring in the segment of the afts towards which mandible moves. That is when mandible moves towards the right then the right side is called as the working side occlusion or functional occlusion. The tooth-conduct occurring in this occlusion is called as functional occlusion and functional occlusion is of two types. Lateral function occlusion and propulsive function occlusion. The lateral function occlusion includes the tooth-conduct that occurs on the canine and posterior side, teeth on the side to which mandible moves. That is lateral function occlusion is the tooth-conduct occurs on the canine and the posterior teeth on the side to which mandible moves. Lateral function occlusion again is of three types that is canine-gated occlusion and tooth-gated occlusion or tooth-functional occlusion. Canine-gated occlusion. Here during the lateral moment of mandible the opposing teeth moves. Here during the lateral moment of the mandible the opposing canine-conduct with each other while there is disocclusion of the whole posterior teeth on the ballast side and on the working side and on the ballast side. Here only canine on the working side contact with each other of the maxillary and mandibular teeth whereas there is posterior disocclusion of teeth on the working side as of the ballast side. It is usually seen in young individuals with unbound admission and this is the lateral function occlusion. In addition to canine-gated we have certain other posterior teeth on the working side also contact. So in group lateral occlusion apart from the canine occlusion there is occlusion of certain posterior teeth also. Such type of contact during lateral moment is followed as tooth-functional occlusion and protrusive function occlusion. It includes some eccentric contacts that occur when the mandible moves forward. That is when mandible protrudes forward there is eccentric contact occurs. This follows protrusive function occlusion. It is ideally the six mandibular anterior teeth slides along the lingual inclines of the maxillary anterior teeth while the posterior teeth seclude. Here there is when the mandible moves forward the six mandibular anterior teeth slides contacts or slides along the lingual inclines of the maxillary anterior teeth while there is posterior disocclusion. And this is the difference between natural and artificial teeth. Naturally there is in other words there is a periodontal inclement support over the natural teeth. There is no ketone ligament in the artificial teeth. And natural teeth function independently whereas artificial teeth function as a group. And malocclusion if present in the natural teeth it is not problematic for years. While artificial teeth the malocclusion goes to the plastic problems. And non-vertical forces are well tolerated in the natural teeth whereas non-vertical forces are supporting or damaging to the supporting tissues for the artificial teeth. And incising does not affect posterior teeth in case of natural dietician. It is a positive function independently incising occurs on the effects only the incisors and the positive teeth are independent of it. While incising affects all teeth on the densities. And second molar is the most favorite position for mastication in case of natural dentition. Here heavy pressures of mastication in the second molar region cause stinting of the teeth. Here the masticatory force should be centered around the premolar molecules in order to have proper function. And bilateral balance is rarely found in natural dentition and if it is present then it is considered as a pre-naturity or interference. Here in artificial dentition bilateral balance is extremely necessary for base stability. Here in natural dentition propensity impulses give feedback to avoid the pre-naturities and interferences. So a habitual occlusion away from the centriplation is established. So the propitone occipital receptors generated from the periodontal ligament give feedback to avoid pre-naturity and interferences. So a habitual occlusion away from the centriplation is established in case of natural dentition. In case of artificial dentition there is no propitone occipital receptors from the periodontal ligament and the denture base rest in the centriplation. Then if it is maturities or interferences in this position cause shifting of this occlusion of the denture base. Then the requirement of complete denture occlusion. The primary remedy is the stability of occlusion in case of centriplation and in the areas forward and latitude. So we have dent circulation earlier. So there should be stability of occlusion in the centriplation position and the areas forward and adequate. And this should be balanced to put in all accepted moments of manageable. And the unlocking of the crust mesiodistrally should be the to allow for the angiol setting of the denture base during tissue deformation or bone absorption. And then another thing is, another thing is the control of horizontal forces by reducing the whole angle crust height according to the residual width height and the endowards relationship. Here the well formed ridges. This is the well formed ridges and the horizontal forces generated by the custard teeth are well tolerated by these well formed ridges. Whereas there is a rigid absorption here and there is also reduction of the crust height to reduce the horizontal forces generated by the teeth towards the ridges. And in case of flat ridges we use crustless teeth or non-annotative teeth. Next is the achievement of liver balance. Liver balance is achieved by ranging the posterior teeth over midline of the crust of the ridges. This is the crust of the ridges and this is midline of the crust of the ridges. So the posterior teeth should be arranged along the midline of the crust of the ridges to achieve the liver balance. Then it's the cutting or penetrating or shearing efficiency of the cutting or penetrating or shearing efficiency of the ocrusal surface of the teeth. It should be there and there should be anterior clearance of the teeth during investigation. That is anterior teeth should be out of contact during investigation. So as the posterior teeth can contact freely. And there should be minimum of lucid contact meaning upper and lower teeth to reduce pressure during function. So the minimum contact between upper and lower teeth to reduce the pressure of the teeth during function. There should be at least a minimum of three point contact in case of galastroclution. Where it can be, the contact can be simultaneous contact of overall positivity can be present but minimum of three point contact should be there for the rhinestones. And requirements of insizing units. Insizing units should be sharp enough to cut efficiently and it should not, as we said earlier, it should not contact during investigation. And it should only contact during the proceed insaisal function. That is when the mandible moves forward the maxillary and mandible teeth come to an end to end circulation. Only in that case the insaisal unit should contact. And it should have flat insaisal gradients as possible considering the aesthetics and phonetics. That is insaisal gradients, it is the overlap between the maxillary and mandible teeth. And it should be as flat as possible in permitting the aesthetics and phonetics. So there should be various operation is achieved. And though there should be constant horizontal overlap to allow for the settling of the base without difference. That is during producing moment of the mandible there should be adequate horizontal overlap between the maxillary and mandible teeth so that the posterior teeth will not interfere with each other and cause dissolution or unsettling of the benefits. Then the requirements of natural working opposing units. There should be, it should be efficient in cutting and grinding and there should be less buckling width to minimize the work load. So the buckling width of the posterior teeth should be reduced to minima. So that the work load divided towards the basal tissues are minima. And it should function as a groove in carrying at the end of the chewing cycle and eccentric discussions. And should be over the ridge cast and as we said earlier the posterior teeth should be arranged at the midline of the ridge crust in the mastigator area for liver balance. For liver balance it should have surface to receive and transmit the, should have adequate surface to transmit the pores vertically and it should sender the work load in the anterior posterior center of the tensor. That is the work load should be sendered along the anterior posterior center of the tensor probably in the primolar molar region. That is ideal region in the concrete tensor where the work load should be sender. And the plane of occlusion should be as parallel to the main foundation plane as possible. And requirements of the balancing occlusion units. The balancing occlusion units should contact on the second molar region when the incisive units contact in function. And there should be contact on the second molar region when the incisive units are in function. There should be contact at the end of the chewing cycle when the bucking units also contact. So at the end of the chewing cycle there is contact on the bucking units. At that time the balancing units should also come into contact. And there should be smooth uninterrupted glide on the balancing units for in case of lateral or protrusive excursions. So that only if there is smooth uninterrupted glide on the balancing units the bucking units come into contact. And these are the theories of complete danger occlusion. The theories of complete danger occlusion must is the bond wheel theory. It is also called as the theory of equilateral triangle. And this theory proposes that the teeth move in relation to each other as dated by the condylar units or controls and the incisive point. This is the condylar units two sides and this is the incisive point. So this form an equilateral triangle and teeth move in relation to each other in accordance with this equilateral triangle. This is considered by the bond wheel theory. And then comes the theory of the conical theory. It is proposed by Hall. It states that the lower teeth, the nadibular teeth occludes the surface of the upper teeth as it occludes the surface of a cone with the central axis tipped 45 degree to the occlusal plane. That is the lower teeth comes contact with the upper teeth as over the surface of a cone with the central axis tipped 45 degree to the occlusal plane. That is described by the conical theory by Hall. And then comes the spherical theory. It is proposed by Monsun. It is said that the occuding surfaces of the lower upper and lower teeth are a part of the segment of the sphere with 18 inch diameter at its center at the region of the flabella. And this is the spherical theory and it is proposed by Monsun. It is unsubstantiated pollution. This is about the unsubstantiated pollution. They are all to factor. They are two types, banished pollution and non banished pollution. There are three types, banished pollution, monoclonal pollution and indolent pollution. And this is banished pollution. Banished pollution is defined as the bilateral and continuous contact of the indelible and posterior and the indelible and posterior region of mass-loving and molecular teeth in centric and eccentric positions. So, as to limit to a less than 15 of the engine during function. Here, we need to set the objectives of banished pollution. The main objective is to improve stability of the engine, to reduce respiratory absorption and so on and to improve oral comfort of the fish. And characteristic requirements of banished pollution. Since that all teeth of the working site should slide evenly against the opposing teeth, no single teeth should produce any interference. No single teeth should produce any interference or disocclusion of the other teeth. There should be contact in balance inside, but they should not disturb the smooth uninterrupted glide in the working site and there should be simultaneous contact during function. That is the teeth on the working site should glide evenly against opposing teeth. In the balance side, they should be contact, but it should not interfere with the smooth gliding on contact of the on the working site. And no single teeth should produce any interference or disocclusion of other teeth and there should be simultaneous contact during function. And this is the working site. And this this is the working site. There should be simultaneous gliding contact on the working site. And balance side, there should be only minimal contact on the balance side, so as there is gliding contact on the working site. And this is for inclusive relation. Here procedures are almost out of contact, but there is contact of the anti-alcoholic. General consideration for banished pollution. You can see that wider and larger the rates and the teeth close up to the rates, the greater is the lower balance. So the teeth should be wider and larger and teeth should be arranged close up to the rates. Then wider the rates and narrow narrow the teeth, but really greater is the balance. We can see that when the red is wider and the occlusion table of the posterior teeth is narrow, but linearly then greater is the balance. And more linearly the teeth are placed to the crust of the ridge, then there is greater balance. And then the more centered the force of occlusion and your posterior bleed then better is the stability of the venture base. Times of balance occlusion. Balance occlusion may be three times that is unilateral balance occlusion, bilateral balance occlusion and propulsive balance occlusion. Unilateral balance occlusion. This is present when there is balance of the venture base, between there is balance between venture base and the supporting tissues. Here we can say that when a ball of food is interposed between teeth on one side, there is space on the, space it is between the propulsive side. So in order to keep balance or liver balance, we should answer to the following points. That teeth should be placed such that there is direct recentral forces on the functional side over the crust of the ridge or lingon to the crust of the ridge. That is the recenting forces acting to that vertically to the crust of the ridge or slightly lingon to the crust of the ridge on the functional side. Then the venture base must cover as wide area as possible of the ridge as possible. Then the venture base should cover the as wide area of the ridge as possible and the teeth should be as close to the ridge as possible. And the narrow bakolingal width of the occlusion food practice table, occlusion food table is to be attained. As discussed earlier the teeth should be very close to the ridge as possible and the bakolingal occlusion food table should be as narrow as possible. Then this is the unilateral balance occlusion. Unilateral occlusion occlusion balance is present when the occlusion surface of the teeth on one side articulate as a group with smooth uninterrupted glide. Here you can remember that unilateral that is the occlusion surface of only one side of the teeth articulate simultaneously as a group with smooth uninterrupted glide which is bilateral. So there is there should be equilibrium out of balance of the teeth. There should be equilibrium or balance of the teeth on both side of the denture. On that is for right-hand left side of the denture simultaneously with simultaneous tooth contact in centric and eccentric positions. It generally require a three-point contact that is one on both side of the posterior teeth and one anterior teeth. And more than a number of contacts that's the balance. This is another advantage of bilateral balance occlusion. It's praying to give the concept of endobolus exit balance. That is food is entered here, endobolus exit balance. Which implies that the introduction of food on one side of the teeth arched or teeth will prevent the opposite side from contacting each other. And bilateral balance is possible to attain during mastication. It's the point of pride. According to Sheppard, Sheppard later gives the concept of endobolus endobalus. According to this, if I leave a chewing food on one side of the teeth with one side of the teeth, the food teeth cut through the bolus and come in contact with the easter for a few fraction of seconds. Hence the stability of the denture is maintained during various moment of manageable during chewing. So the food cut through the bolus, teeth cut through the bolus of food and there should be a fraction of contact on the teeth for a fraction of seconds. Hence the denture, stability of the denture or then the stability is maintained during various moment of manageable during chewing. And then Hoover and Hudson conducted a 24 hour test and which on this test they said that normal individual makes masticated tooth contact for only 10 minutes a day compared to 4 hours of total tooth contact during parfunctional and parfunctional activities. So for this 4 hours of tooth contact, bilateral banister pollution is necessary. As said earlier, bilateral banister pollution improves the stability of the denture, reduces the rupture of the liposuction and so on and improves generally the foreign well-being of the patient. So these are some of the roles dictated by the wing line. That is some of the advantages of the banister pollution. In this contact, if the contact is interruptive or reflective, interruptive or reflective and not bilateral, the denture base will not be stable. Bilateral banister contacts is a must-for terminal arc of closure for the seeking of the denture in a stable position. If the contact is interruptive or reflective and not particular, the denture will not be in a stable position. So bilateral banister pollution is necessary for the tooth properly in its position. Also bilateral banister pollution is necessary at the time of solving saliva, closing of the arc to receive the dentures and practice some of the teeth at the time of stress. Also bilateral banister pollution is able with the bilateral banister pollution patient is able to achieve stable and repetitive position of the dentures. Another thing is that during bilateral banister pollution, the bases are stable even in the times of proxiesome and they are even tight when the patients apply the teeth. That is, during the proxiesome and also when the person can devoid of pledging the teeth at both the time, the bilateral banister pollution keeps the denture shape. Some of the points these are some of the disadvantages of the bilateral banister pollution. That is, it tends to encourage the patient to be in lateral or proprosy grinding, although this habit is confined to persons or other patients with only irrelevant muscle activity. So it should not be encouraged to continue the patient in lateral proprosy grinding. Other thing is that it is typical to achieve in mouth where there is increased vertical incisor overlap. That is, in case of persons with increased vertical incisor overlap, it is better to retain the overlap than to reduce the overlap to achieve in articulate parts. That is, in persons with increased vertical overlap, banister pollution could be sacrificed and the vertical overlap of the patient should be maintained so that the patient can attain maximum aesthetics and the genetics. Another thing over disadvantages of the banister pollution is that it is semi-adjustable or fully-adjustable or anti-adjustable publishing record required for achieving banister pollution. Another one. Next is the proprosy occlusion balance. This is present when the mandible moves essentially forward and the occlusion contacts are smooth and simultaneous in both posterior and the anterior region on both right-hand left side. So there is an occlusion balance of those when mandible moves forward and there is still bilateral in both the anterior and posterior region on both the right and left side. It is slightly different from bilateral balance occlusion because in bilateral balance occlusion there is at least three point contacts, one on each side of the posterior region and one anterior. So the factors influencing balanced occlusion, they are inclination of contellar guidance, incisal guidance, coordination of client of occlusion, cuspial angulation and commensate incontinence. So these are the five basic factors that determine the balance occlusion. The first one is the inclination of contellar guidance. It is the path generated by the contail on the travoids through the posterior slopes of the glenode posa. This is the path to contellar guidance. So the mandibular guidance achieved by the path traversed by the contail on the posterior slopes of glenode posa. That is the contellar guidance. Then comes incisal guidance. This is incisal guidance. This is the angulation between the occlusion plane and the line passing through the tips of the incisors, connecting the tips of the incisors as in the sedative plane. And this is the incisal grader gate angle and this is the incisal guidance. And then comes the plane of occlusion. It goes through the tip of the canine through the molas and the primolas, the occlusion of the molas and primolas. And then comes the compensatic curve. The compensatic curve passes through the tip of the canine through the crucial surface of the molas and primolas and molas and passing through the premise of mandible to the ideal surface of the contail. Then comes the hospital inclination. That means the angle of the cusp. The hospital inclination of angle of the cusp. These are the five factors called a synasculpt. And this is given by the equation incisal guidance into contailer guidance equals plane of occlusion and compensatic curve and cuspal height and compensatic curve. So here the contailer guidance is a constant factor. It cannot be changed. So if the contailer guidance is steep, the incisal guidance has to be shallow and the compensatic curve, plane of occlusion and the cuspal height, all three have to be steep. And this is the incisal guidance. This is given by the Annabaskian. Here also the same factors, five factors. This is the inclination of contailer guidance. If it is increased, then incisal guidance has to be decreased and the cuspal angle, plane of occlusion and the compensatic curve has to be steep. Same is the thing with this for other factors, incisal inclination of incisal guidance, cuspal angle, height of the cuspal angle incisal guidance, orientation of plane of occlusion and the compensatic curve. All other four factors are to be altered according to this. And then comes the contailer guidance. It is the mandibular guidance generated by the contail and the articulator is traversing through the posterior slopes of glum and fossa. This contail passes through the, this is the posterior slopes of glum glum and fossa and while the contail travels through the posterior slopes of glum and fossa, the mandibular guidance is achieved and this is the contailer guidance. The contailer guidance is a path followed by the contail in the temporal irregular joint. It is obtained by the protrusive registration record in the Hanow's articulator. Hanow states that inclination of contailer guidance is an antilagal conception. The contailer guidance is an antilagal conception and it is precise and constant. It is the primary detector of the occlusion. And the curved screen explains that contailer path is made for the varying incisal guidance. As the incisal guidance varies, contailer guidance may have slight change, but almost the contailer guidance is fixed for one patient. When that short, that contailer path varies so into variable pressures of function, that is during mastigator function, somewhat contailer guidance has a slight variation but it is almost constant from patient to patient. Then comes the significance of contailer guidance. Increasing contailer guidance will increase the jaw suppression during protrusion. So a patient with steep contailer guidance have an increased jaw suppression. With patients with steep contailer guidance, incisal guidance also should be reduced to degrees the amount of jaw suppression during protrusion to achieve the occlusion balance. And this factor cannot be modified. Again we have said that contailer guidance is a constant factor. It cannot be modified and all other factors should be modified to compensate the effect of this factor. Then comes the incisal guidance. Then comes the incisal guidance. Incisal guidance is the incisal guidance. This is the influence of the contact in surface of mandibular anteriors. Then it passes through the slope and includes slopes of the maxillary anteriors when the mandible moves in protrusion. That is incisal guidance. And incisal guide angle, this is the angle, the angle found by the intersection of plane of occlusion and line between the sedative plane passing through the incisal edges of maxillary and mandibular when the teeth are in maximum intersection. Then comes the incisal guide angle. This is the overjet. This is termed as overjet. The distance between the incisal tip of the maxillary and mandibular incisals is termed as overjet. And this is the overbite. The vertical relationship is the overbite. Angle of incisal guidance is largely under the influence of the test. So it can be changed or influenced or somewhat altered by the dentist. And the factor is also influenced by the amount of horizontal and vertical overlap. This is the horizontal overlap and here the incisal guidance is shallow and this is the vertical overlap and this is the vertical overlap. So greater the horizontal overlap, lesser the incisal inclination or shallow is the incisal guidance. Lesser the angle of inclination or shallow is the incisal guidance. And lesser the vertical overlap. This is the vertical overlap is also lesser than lesser angle of inclination. the angle of inclination becomes lesser when this overlap is reduced. So incisal guidance should be as shallow or as flat as possible permitted by the phonetics and the aesthetics to achieve the valence conclusion. During protrusive movement, during protrusive movement, mandibular teeth move forwards as per the incisal guidance. Then as this protrusive movement of the mandibular teeth, the teeth are moved, mandibular teeth move forward as per the incisal guidance. For the complete dangers as we discussed, incisal guidance should be flat as the aesthetics and phonetics will terminate. If the incisal guidance is steep, the steep causal plane of steep common center curve is needed to balance the operation. When mandibular teeth have sufficient vertical overlap, a corresponding horizontal overlap should be set to prevent the dominated incisal guidance to achieve a crucial balance. That is when the mandibular teeth is have a considerable vertical overlap, a common compensating horizontal overlap should be given so that the incisal guidance is as flat or shallow as possible to achieve the occlusive balance of the posterior teeth. Then comes the plane of occlusion. This is the plane of occlusion which is this imaginary surface which is anatomically related to the cranium and it theoretically touches the incisal edges of the anterior teeth or incisors and the occlusal surface of the posterior teeth. This is the plane of occlusion and this landmark also provides anterior-positive inclination of the ocrusal plane and which is nearly parallel to the lower mean foundation plane. That is this anterior plane, anterior-positive inclination of the plane occlusion should be nearly parallel to the lower foundation plane and this landmark also creates an occlusal plane which is essentially parallel to the allatragus line. The occlusal plane as we discussed earlier has to be parallel to the allatragus line. This is the occlusal plane, here is the occlusal plane and it is parallel to the allatragus line. There is a allow of the nose here to the tragus of the ear. The occlusal plane can be added to a maximum of 10 degree. There is a flat occlusal plane and according to the change in other factors it can be altered to a maximum of 10 degree. According to Shadi, the occlusal plane of orientation established initially can be altered subsequently to serve the other purpose. That is, occlusal plane which is initially established is this and it can be altered according to various purposes. And it may be lost in establishing the compensatory curve later. That is, this is the initially attained occlusal plane and it may be lost while achieving the compensatory curve later. According to Bowsher, locating occlusal plane can be different according to which favors the weaker of the two ridges and causes concern to the aesthetic and mechanical subjectivity. That is, the occlusal plane may be altered to favor the weaker of the two ridges. That is, maxillary or manipular ridges either of the two ridges may be weaker or the ridge may be thin. And then the occlusal plane is altered and causes aesthetic and mechanical trouble. And in other cases, the soft tissues around the ridges direct forces around the danger as they did around the natural teeth. Then the occlusal plane should be oriented exactly when the natural teeth are present. That is, how the occlusal plane was present while the natural teeth are there, the same relationship should be given to the occlusal plane while arranging it in the artificial teeth also. By positioning the anterior teeth correctly for aesthetic appearance and the posterior end of the occlusal plane with the level of the two-third of the retromolar path, then the occlusal plane is fixed. That is, the same means of locating the occlusal plane. That is, I setting the anterior teeth according to the aesthetics. That is, the tip of the canine up to the commissures of the lower lip and the posterior end of the occlusal plane with the two-third level of the retromolar path, then the plane of occlusion is almost fixed. Another necessary alteration for the occlusal balance must be made on other factors. Then comes the common sector curve. It is the anterior posterior and lateral curvatures in the anterior posterior and lateral curvatures appearing during the alignment of occluding surfaces and incisors like this of the artificial teeth which is used to develop balanced occlusion. As the definition states, the posterior and lateral curvatures during the alignment of occlusion surfaces and incisors like this of the artificial teeth which is used to develop the balanced occlusion. Here the primary function of commensating the curve needs to provide balance during protrusive angular movement. Without this curve, it would be necessary to change the end of occlusal plane at an angle. So, the commissure curve helps in achieving balanced occlusion during protrusive movement of the mandible. Otherwise, if there is no commissure curve, then the plane of occlusion has to be shifted or altered to a greater extent. And steep quantilarpath requires steep commissure curve to achieve balanced occlusion. That is, if the commissure steep quantilarpath is there, then the commissure curve also has to be made steep to achieve protrusive balanced occlusion. Here, in case of steeper incisal guidance, there will be ideal interferences and causes loss of balancing molar contacts. So, the commissure curve should be made more steeper. And the commissure curve is produced to produce eccentric balance in monoplane occlusion. As we discussed earlier, it is there to produce eccentric or protrusive balance in monoplane occlusion as well. This commissure curve is achieved by arranging the first tooth by raising its distal end and continuing this curve by far of the race in the second molar with the distal surface located at the level or 2-3rd the level of protromolar path. That is, there is a distal rise in the, there is a rise in the distal aspect of the second molar tooth at the level of 2-3rd at the level of 2-3rd the retromolar path. This distal rise in the distal surface of the second molar. And irreposterably, it should exceed, should not exceed, this is the anterior posterior leaf, it should not exceed, the rise should not exceed the 20 degree. And mediolaterally, the rise or tilt of the commissure curve should not exceed 10 degree. This is the mediolateral commissure curve and it should not exceed 10 degree and this is the anterior posterior commissure curve. It should not exceed 20 degree. This is 20 degree and this should not exceed 10 degree. And the times of commissure curve, the anterior posterior curve is also called as carbospy. And the mediolaterally, there are two curves and they are Mansoon curve and Wilson curve. This is the carbospy. The carbospy is the anterior posterior curve beginning with the cosmetic of matibular canane. Primolyllars and molars traversing through the anterior region of primors and ending with anterior portion of the quantity. And this starting with the beginning with the tip of the canane through the cosmetic of primolars and molars traversing through the anterior portion of primus of manubule ending with the anterior portion of the contact this is the anterior posterior curve and it is called caribose p. In the conversatory curve or caribose p, the conversatory curve for caribose p in the artificial transition this is anterior posterior curve and the posterior teeth set on this curve will continue to remain in contact during propulsion that is during propersive moment teeth set on the caribose p will continue to remain in contact. Next is the curve of Wilson, George Wilson stated this curve of Wilson and it is a mediolateral curve it contacts the buccal and lingual custody of molars on each side this is the buccal and lingual custody of molars on each side of the arcs are conducted by this curve of Wilson. The mandibular arcs there is inward inclination there is a mandibular arcs there is inward inclination of the posterior teeth making the lingual cusp slightly below the buccal cusp and the resenting covenants setting curve is a concave one the curve is concave Wilson's curve and in the maxillarity there is outward inclination and causing the buccal cusp to be slightly higher than the level of the lingual cusp making the conversatory curve of Wilson Wilson's curve to be slightly convex in the maxillarity region and teeth set on this curve will have the lateral balance of occlusion and then the contour of monsoon. This is the ideal curvature of occlusion this ideal curvature of occlusion in which the cusp tip or the incisal edges touches or confirms to a segment of sphere of 18th diameter with the center at the region of club and we have discussed this in the theories of occlusion that is the spherical theory first given by the monsoon the same as that and this then comes the cusp inclination and the cusp inclination is the angle made by the slope of the cusp with the cusp plate this is the slope of the cusp and the this is the cusp plate the angle given by the slope of the cusp the cusp plate measured is you distally or accordingly it is an important factor and that can be modified and the effect according which modifies according to the effect of plane of occlusion and the commissary curve. Angulation of the cusp is more important than the height of the cusp this is the height of the cusp but the angulation of the cusp is more important than the height of the cusp the misiodic still cusp height causes interdigitation of the tooth and cause make the repositioning of the tooth during settling of the interpaces is possible and to reduce this the misiodic still height is very much reduced and only the buckwheeling and in-lines are considered as a determinant of balanced occlusion. Only buckwheeling and in-lines and need to be considered as a determinant of balanced occlusion misiodic still cusp height should be eliminated to achieve the balanced occlusion. In shallow by cases the cusp angle should be reduced to achieve the balance incisal guidance. In shallow by cases that is there is the horizontal overlap almost exceeds the vertical overlap then the cusp angle should be reduced to achieve incisal balance or incisal guidance. In case of deep bite cases that is with steep incisal guidance the jaw suppression is more during protrusion and teeth with height the cusp inclination are required that is the incisal guidance is steep that is vertical overlap is more than the horizontal overlap then the jaw suppression will be more during the and you have to portion and the teeth with the height cusp in lines are required to produce balance occlusion. Then the interaction of the five factors. Of the four factors we can control two of them. We have said that the condylar guidance is a stable and precise factor and cannot be changed and the out of other four factors the incisal guidance and the plane of occlusion can be only slightly altered because of the aesthetic and phonetic reasons incisal guidance and plane of occlusion should be closer for achieving the aesthetics and the phonetics. The other important working factors for dentists to manipulate are the pulmonary centric arrow and the inclination or angulation of the cusp on the occlusal surface of the teeth. So dentists can alter the pulmonary centric arrow and the cusp of inclination to achieve balance occlusion and the characteristic of balance occlusion in complete dentists. In centric relation in anterior teeth there is no contact and the posterior teeth there is multiple uniform contact exist. The protrusive relation in the anterior teeth there is again maxillarean manipular teeth contact in the anterior teeth during protrusive relation. The posterior teeth doing semi-anatomic and anatomic teeth multiple posterior buckle to buckle and lingual to lingual cast contact can be seen between maxillarean manipular teeth. In flat plane or a neutral centric occlusion there is only second molar contact if the comacetric curve exists. That is flat plane or neutral centric occlusion there is second molar contact in the second molar region if the comacetric curve is achieved or if there is balancing ramp contact if the true flat plane is achieved. If there is no balancing comacetric curve or balancing ramp and there is a vertical overlap in central overlap then there is no balanced occlusion and during the protrusive relation in lateral occlusion. In lateral occlusion during the working side that is side to which mandible moves there is maxillarean manipular and generative contact on the working side and the posterior teeth buckle and lingual cusp of the maxillarean manipular teeth and contact. Again posterior teeth there is buckle and lingual cusp of the maxillarean manipular teeth comes into contact with each other. Lingualized occlusion the maxillarean lingual cusp will be in contact with the mandible or lingual cusp. In lateral occlusion then the balancing side that is the side which moves to the median, median side during the sideward moment of mandible the anterior teeth contact. The maxillarean manipular anterior teeth will be coming in contact and balancing side also. In the posterior teeth the lingual cusp of the maxillarean will be in contact with the buckle cusp of the mandible or that is mandible as moved towards in the balancing side mandible is moved towards the median plane so the buckle cusp of the mandible will be in contact with the lingual cusp of the maxillarean. With monoplane occlusion usually there is only second molar contact or contact in the balancing. Cusp to teeth there are multiple contacts of the posterior teeth are posited. This is the reference. Hope you understand the concept of answer occlusion in detail. So, I will come into another topic. Thank you.
