 Hello everyone welcome back to another session in dentistry and more today we will be seeing a small topic from oral and maxillofacial surgery that is Tori maxillary and mantibular Tori which will be dealt under pre prosthetic surgery there are lots of things which comes under pre prosthetic surgery but this session is about Tori so prosthetics is a replacement of missing teeth lost or continually absent so once the process is received the patient can perform many functions such as mastication chewing the facial expression but some patients may not be able to receive a process is because of few problems such as bone atrophy soft tissue atrophy or soft or hard tissue problems which is localized so we need to perform pre prosthetic surgery for such patients to receive a process is so there are many bony procedures such as the alveolar plasty alveolactomy reduction of myelohydrate reduction of genial tubercles or elimination of unfavorable undercuts and the Tori it can be a maxillary Tori or a mantibular Tori so maxillary Tori or palatal Tori are usually present on the midline of the heart palate so most palatal Tori are less than 2 centimeter in diameter but the size can change throughout the life so when do we need to remove a maxillary Tori that is the indication of removal of maxillary Tori Tori not all the time we should remove maxillary Tori to receive a complete injury or maxillary complete injury but the indications are an extremely large torus extremely large which actually fills the palatal vault or a torus that extends beyond the post dam area the posterior part where the actual retention features lies then if there is a traumatized mucosa over the torus or if there is deep bony undercuts if there is deep bony undercuts which interferes with the danger insertion and stability or if the Tori interferes with the function such as pH or deglutination so we can leave behind the small Tori which can be relieved during the denture construction but we need to remove the large Tori because of these indications so how do we perform the maxillary Tori removal so procedure in this the midline incision is given can see the picture here the midline incision is given in the palette and flap is reflected with a Y shaped releasing incision you can see the releasing incision like this then the torus is removed by making multiple cuts of it and then the flap is sutured a palatal splint is given to prevent hematoma formation so the procedure is not very complicated we are using a Y shaped releasing incision with a palatal midline palatal incision then torus is removed by making multiple cuts then the flap is sutured then there should be a palatal splint to prevent the hematoma so in case of mantibular torus so this mantibular Tori is an exostosis nothing but a bony growth this is found on the lingual surface of the mantible which is opposite to the canines and primolas okay canines and primolas so it will be just opposite to these teeth in the mantible they too also have problems with denture retention in the mantible because of the loss of marginal seed in the primola region there the actual retention occurs other than the retromolar area so this exostosis create a problem with the retention of the mantibular denture so it is indicated again almost same as a maxillary Tori Tori causing the lingual undercuts and which interferes with the lingual flange extension when the mucosa overlying is ulcerated or the large Tori interfering with speech and deglutation so the procedure bilateral lingual and inferior alveolar anacetia is given incision extending from 1 to 1.5 centimeter beyond each Tori then always leave behind a band of tissue attached to the midline between the anterior extent of the two incision so when the Torus has a small pedunculated base mallet and an osteotomy is used to cleave the Tori from the medial aspect of the mantible so the direction of initial burr is parallel to the medial aspect of mantible to prevent the fracture of lingual or inferior cortex then we can use a bone file to smoothen the lingual cortex we can use palpation method to check for proper contour and presence of any undercuts then we can go for a continuous suture then goes packs of placed and retained for the next 12 hours so that was about the maxillary and mantibular Tori its indication and little bit about its procedure so it's very commonly asked short not the maxillary Tori and mantibular Tori so I'll come up with a similar topic in oral and maxillofacial surgery thank you
