Evaluation and Comparison of Occlusal Contacts Using T-Scan in Maximum Intercuspation and Balanced Occlusion at Different Values of Semi-Adjustable Articulator – An In-Vitro Study

Abstract

Introduction The purpose of this study is to evaluate the occlusal contacts using T-scan in maximum intercuspation and balanced occlusion and comparison of the results.

Methods: Edentulous molds are used to pour casts in dental stone. Denture base and occlusal rims were fabricated and then mounted on Hanau wide vue semi-adjustible articulator at different values. In the first group (n=6), teeth arrangement was done in maximum intercuspation and the other group (n=6), had teeth arranged in balanced occlusion. The occlusal contacts of both the groups were checked with T-scan in various mandibular movements and the results were evaluated.

Results: No statistically significant difference was found between both the groups tested.

Conclusions: Within the limitations of the current study, it was seen that there were no statistically significant differences seen in occlusal contacts when a balanced occlusion denture was fabricated using conventional methods to that of using an 8” occlusal plane template. Further in-vivo studies are required to ascertain whether one is superior when compared to the other.

Key Messages: Balanced occlusion is a preferred occlusal scheme for complete denture patients to enhance stability of dentures. However, the occlusal contacts in balanced occlusal scheme has not yet been proven to be superior when compared with conventional methods.
