Abstract

Purpose: Most of the former studies about the occlusal contact patterns during the mandibular movement focused on foreigner. The purpose of this study is analyzing the occlusal contacts of young Koreans by using T-Scan system. Materials and methods: The sample size was 87 and the occlusal contacts of each right and left lateral movements were measured from the maximum intercuspation to the 3mm excursive position for three times respectively. All of the occlusal contacts were double checked through the thin metal foil. The results were categorized as two; 1) considering occlusal contact patterns on working side only, 2) considering occlusal contact patterns on working and nonworking sides. Results: The results showed that the nonworking side occlusal contacts play major roles in the lateral mandibular movement. In both cases of considering with and without the nonworking side occlusal contacts, the group function was the most prevalent. In the working side, the contacts were the most frequent in canine and the frequency of contacts was decreased as the distance was increased from canine to molar. In the nonworking side, the contacts were the most frequent in second molar. And the gender factor was statistically significant (${\alpha}$=.05), as females have more nonworking side occlusal contacts in this study. Conclusion: Among the three factors of anterior guidance, the group function was the most dominant factor. The analysis of 87 samples showed that canine contact was the most frequent in the working side and second molar contact was the most common in the nonworking side.

목적: 교합접촉 분석에 대한 연구는 외국인을 대상으로 이루어져왔다. 이번 연구에서는 T-Scan을 이용하여 하악 측방운동시 교합접촉 분석을 통해 한국인의 교합 양상을 파악해보고자 한다. 재료 및 방법: 87명을 대상으로 T-Scan을 이용하여 하악 측방운동시 교합접촉을 분석하였다. 최대교두감합위에서 측방으로 3 mm범위까지 교합접촉을 측정하였으며, 최대교두감합위, 우측방운동, 좌측방운동을 각각 3회씩 측정하였다. 교합접촉은 thin metal foil을 이용하여 재확인하였다. 결과는 균형측 교합접촉 고려하지 않은 경우와 고려한 경우로 나누어 정리하였다. 결과: 하악 측방운동시 균형측 접촉 고려 유무에 따라 결과에서 많은 차이가 관찰되었으며, 두가지 분류 모두에서 군기능유도가 가장 우세하게 나타났다. 작업측에서는 견치에서 가장 많은 접촉빈도가 관찰되었으며, 견치에서 구치부로 멀어질수록 접촉빈도는 감소하는 양상을 보였다. 균형측에서는 제 2대구치에서 압도적으로 많은 빈도로 관찰되었다. 성별에 따른 균형측 접촉 빈도는 여성에서 더 높은 균형측 교합접촉이 관찰되었으며 이는 통계적으로 유의성이 있었다(${\alpha}$=.05). 결론: 전방유도의 양상 중 군기능유도가 가장 우세하게 나타났다. 작업측에서는 견치에서 가장 높은 접촉빈도가 관찰되었으며, 균형측에서는 제 2 대구치에서 가장 높은 접촉빈도가 관찰되었다.
