 Welcome back to another session in dentistry and more. So this topic in prosthodontics is resiliency like effect or real life. So it is nothing but the resilient ridges which creates problem for danger creation or the maxillomandibular relationship registration. So real life is the beginning lectures of resiliency like effect was first reported by Hannau. So the complete denture they rest on basal seat area which primarily oral mucosa right oral mucosa and also residual alveolar ridge. So the oral mucosa on which the complete denture are fabricated is displacable and also compressible. So this factor was first described by Hannau as a real life. So this real life effect. So it plays a very important role in all steps of complete denture fabrication. Even from the primary impression, bottom molding, final impression, jaw relation, trine procedure and remounting and even follow up. So it can be a cause of error in fabrication. So when there is mechanical or pathological effect on the residual alveolar ridges and it creates a fibrous change in the ridge this will become the resilient ridge which is commonly seen in mandibular region and also in maxillar anterior region. And there are many factors which affecting the real life. The one is the consistency of mucosa, consistency. So consistency means flabby ridge or hyperplasia of tissue. So all those things will create problems for taking impression or creation of a good retentive complete denture, flabby tissue or even hyperplasia of tissue. And then if there is excess bond loss during extraction and also person's general health also affecting the ridge and the elderly tissues take longer time for recovery after the moderate mechanical force compared to the younger people and the paramedic functional habits also produce the change in residual ridge. And also the flabby ridge seen in maxillary anterior region where the maxilla is complete denture where the mandible is having natural teeth only at the anterior portion. So the continuous trauma by the natural anterior tooth to the ridge through the denture will cause a resilient ridge at the maxillary anterior region. So that is upper denture with lower natural anterior tooth. So this combination so lower natural anterior tooth will create pressure on upper denture especially in the anterior region it will become resilient ridge the anterior part of upper denture I mean the upper residual ridge will become anterior ridge will become resilient due to the action of lower natural tooth. So if you have a resilient ridge in oral cavity we need to take precaution at all steps of denture fabrication that is from preparing the mouth for processes then impression techniques and application then even for centric relation trying and application and even also for denture insertion. So at all levels we need to take precautions to manage the resilient like effect that is a resilient ridge. So the techniques we apply for each step is elaborate it will not be asked for a long history this is commonly a short note so I am not going into detail the steps to manage real F problem in each level of denture fabrication. So I just want to give an insight into the concept of real F. So this is nothing but the change of fibrous change in the ridge due to the mechanical or pathological effect or force on the ridge. So hope you understood the small concept of real F I will come up with in your topic in Procedure Analytics. Thank you.
