목적: 이갈이와 편심위 유도양상 및 균형측 교합간섭과의 연관성에 대해 분석해 보고자 한다. 연구 재료 및 방법: 이갈이와 비이갈이군 및 성별에 따른 군기능 교합 및 균형측 교합간섭의 차이를 비교하고 편심위 유도 양상 및 이갈이와 균형측 교합간섭간의 상관성을 알아보기 위해 제3대구치를 제외한 상실치가 없는 26 - 37세 사이의 100명의 유치악 성인(이갈이군 39명, 비이갈이군 61명)을 대상으로 실험을 하였다. 디지털 교합분석장치 T-Scan system 을 이용하여 최대교두감합위, 좌·우측방 편심위 운동을 측정하여 균형측 교합접촉의 유무를 판별하였으며 각 대상의 편심위 교합유도 양상에 대해서도 측정하였다. 디지털 교합분석 장치 검사 후 교합지를 이용하여 접촉되는 치아를 재확인 하였다. 결과: 군기능 교합이 이갈이군에서 61.5%, 비이갈이군에서 47.5%로 가장 높게 나타났다. 남자는 군기능 교합이 58.9%, 여자는 37.0%로 나타났다. 균형측 교합접촉은 전체 100명 중 48명에서 나타났고 이갈이군에서는 51.2%, 비이갈이군에서는 46%였다. 통계적으로 이갈이와 균형측 교합접촉간의 유의성은 나타나지 않았다. 성별에 따른 균형측 교합접촉의차이도 없었다. 결론: 이갈이와 균형측 교합 접촉간에는 상관관계가 없었다. 이갈이군에서 군기능 교합이 가장 높게 나타났다.
Abstract
Purpose: The purpose of this study was to analyze correlation between bruxism and occlusal contacts on balancing side. Materials and Methods: The purpose of this study is to compare the difference of group function and balancing side occlusal contacts according to bruxism and sex, A total of 100 adults that aged 26-37 years (39 bruxers and 61 non-bruxers) were examined. The lateral excursion and balanced occlusal contacts were analyzed to determine the correlation with bruxism. The occlusal contacts were recorded by T-Scan system and articulating paper. Results: The group function was the highest in 61.5% of bruxers and 47.5% of non-bruxers. In comparison between males and females, group function was 58.9% in males and 37.0% in females. Occlusal contacts on non-working side occurred in 48 out of 100 patients. There were 51.2% of the cases in the bruxers and 46.0% in the non-bruxers. Statistically, there was no correlation between the bruxism and occlusal contacts on non-working side. There was no correlation between sex and balancing occlusal contacts. Conclusion: There was no significant correlation between bruxism and occlusal contacts on non-working side. The group function was the highest in bruxers when lateral excursion was occurred.
