Critical review of materials and techniques used for fabrication of hollow bulb obturator

Abstract

S38 The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 Introduction: Occlusion is considered to be the most important discipline for the maximum possible efficiency of prosthesis replacing missing teeth or restoration. A harmonious occlusal relation allows the prosthesis to function harmoniously without disturbing the stomatognathic system resulting in less number of temporomandibular disorders, bruxism habit, trauma from occlusion and other associated diseases. Summary: Over the years various modalities have been used to evaluate occlusion such as waxes, articulating papers, foil/ film/silk strips and newer materials such as the T-Scan, dental prescale and virtual dental patient. The reliability, sensitivity, marking ability and method of use are different and based on their type and character. Factors like oral environment, plastic deformity and interpretation of clinician is also a contributing factor. Hence a thorough knowledge about the various available occlusal indicator methods/modalities, their method of usage, understanding of interpretation & limitation is essential prior to their usage. This review will give insight to various modalities commonly available discussing evidence and practicality of their application. The clinical challenge is to prevent the consequence of occlusal discrepancies by making appropriate, evidence-based minimum adjustments to deliver a realistic treatment with reliable outcome. Conclusion: this presentation will comprehensively discuss the transition of occlusal evaluation methods from waxes, occlusal films to the latest & most resent digital modalities.
