Abstract

The objective of this study was to analyze occlusal contact pattern of 33 young adult males with normal occlusion during lateral excursion using T-scan III system which can measure the dynamic occlusion. Occlusal contact patterns were examined and categorized in non-working side disclusion point(more functionally acceptable position) not canine-to-canine position. Disclusion time, occlusal force, and occlusal force distribution ratio of upper canine at disclusion point during lateral excursion movement was also measured and compared among the groups divided according to contact patterns. The results showed that group function was clearly more dominant than canine guidance and other occlusal contact patterns different with existing patterns were found. There were significantly difference between groups in variables of T-scan measurement. T-scan III system is effective tools to analyze and evaluate occlusal contact patterns, disclusion time, occlusal force, and occlusal force distribution ratio of upper canine at disclusion point.

이 논문의 목적은 시간에 따른 교합의 변화를 측정할 수 있는 T-scan system을 이용하여 젊은 성인 남성(33명)정상교합에서의 하악골 측방운동 시 교합접촉 양상을 분석하는 것이다. 정해진 하악 위치에서의 교합접촉이 아닌, 기능적 범위 내에서 비작업측 교합이개 시점에서의 교합접촉 양상을 분류하고 분류된 군 간에 교합이개 시간, 측방유도 시 견치가 담당하는 교합력의 비율, 측방운동 시 가해지는 교합력 등을 비교하였다. 연구 결과 기존의 분류와는 다른 측방접촉들이 존재하였고 군기능 유도가 우세하게 나타났다. 교합이개 시간, 측방유도 시 견치가 담당하는 교합력의 비율, 측방운동 시 가해지는 교합력 등에서 군 간의 유의한 차이를 나타내었다. T-scan system은 교합접촉 양상을 분류하고 교합력, 교합이개 시간, 견치가 담당하는 교합력 비율 등의 항목을 비교 분석하는데 있어서 유용한 도구이다.
