INTEROCCLUSAL RECORDING MATERIALS: A LITERATURE REVIEW

Introduction: An accurate interocclusal record is necessary for the delivery of fixed prosthodontic restorations. There are various materials and techniques used to obtain an interocclusal record in order to facilitate mounting of the dental casts on an articulator. The interocclusal record refers to the vertical and horizontal relationship of the maxillary and mandibular teeth. The clinician should have an understanding of various interocclusal recording materials, their modifications, shortcomings and awareness of its use in different clinical conditions. Materials and Methods: An electronic search was conducted using the PubMed Database from 1960 to 2020 using the keywords “bite registration materials” OR “occlusal registration materials” OR “interocclusal recording materials.” The articles pertaining to these keywords were further analysed. Results: The search identified 574 articles, out of which 563 articles did not fulfil the inclusion criteria and were excluded from the study. Hence 11 research articles were analysed for the review. Conclusion: Accurate interocclusal records are necessary to deliver high quality, predictable and precise fixed prosthodontic restorations. Establishing a tripod of opposing tooth contact is a fundamental principle to dictate accurate mounting of casts, and thus delivery of a well-fitting restoration. Furthermore, the review outlines the clinical guidelines and recommendations for accurate use of interocclusal recording materials in different clinical circumtances.
