Evaluation of pattern of occlusal contacts in lateral excursion using articulating paper and shim stock: An in vivo study

Abstract

Aim: This study was done to evaluate the pattern of occlusal contacts in lateral excursion and compared the relative accuracy of shim stock and articulating paper for determining occlusal contact patterns. Material and methods: The patterns of occlusal contacts of 70 young adults were examined in various lateral positions with shim stock and articulating paper in regulated lateral positions 0.5, 1, 2, and 3 mm from the maximum intercuspation. Results: Most contact patterns belonged to group function and a few to canine protection when only working side contacts were considered. When both working and nonworking side contacts were considered, nearly half the contact patterns were those other than canine protection and group function. Shim stock exhibited superior accuracy and reliability as compared to the articulating paper. Conclusion: In the lateral excursion other than canine protected and group function, there exists some other occlusal contact pattern. Shim stock exhibits superior accuracy and reliability as compared to the articulating paper. Clinical Relevance to Interdisciplinary Dentistry It is important to understand how to evaluate the type of existing occlusion before any restorative procedure is undertaken It helps to arrive at the best scheme of occlusion for any restorative procedure It also provides a background on the various methods used to assess the occlusal contact in restorative dentistry.
