Comparative evaulation of condylar guidance obtained by digital panoramic radiographic images with that of obtained during jaw relation and try-in using two different interocclusal record material in completely edentulous patients: an in vivo study

Abstract

Background: In completely edentulous patients, maintaining the patient's TMJ health and intraoral components is very important. This can be achieved by an accurate interocclusal record, which can we taken by various materials and also at various stages. Simulation of the temparomandibular joint anatomy and mandibular movements is possible on a semi adjustable articulator which is use widely in prosthodontics. Transferring the record on articulator is a critical step in fabrication of complete dentures so it should be done precisely to reduce chair side time and also to avoid complications for patients. This study examines which material is more accurate and also records which stage gives more precision, by comparing the Condylar guidance on radiographs. This is because it has consistent bony landmarks and is comparable to clinical methods in terms of standardisation. The objective will be to determine the inter occlusal records created during Jaw Relation stage and Try-in using reinforced wax and Polyvinyl siloxane and compare these values to the condylar guidance obtained by OPG. Methods:  Recording the Condylar Guidance value on OPG, obtained with tracing Glenoid fossa, Articular eminence and the Frankfurt Horizontal Plane. Followed with conventional steps in making complete dentures, at jaw relation and try-in stage. we will record values of condylar guidance with the two different Interocclusal record materials. Expected result: It will help the clinicians to get knowledge about obtaining precise condylar inclination angle by using right interocclusal record materials. Conclusions: This study will help us to obtain condylar inclination which inturn helps the patients satisfaction as it maintains the patient's TMJ health and intraoral components.
