Abstract

Objective. This study was conducted to observe the effect on appendage muscle strength according to increase in occlusal vertical dimension. Materials and methods. Ten males with a mean age of 21 were selected. The tested occlusal splints were made at the position of increased occlusal vertical dimension of 2mm,3.5mm and 5mm from the intercuspal position. Before and after wearing occlusal splints, the appendage muscle strength were tested by Cybex II dynamometer (Lumex Inc., Ronkonkoma, NY, USA). Results. Statistical analysis using the paired t-test revealed significant differences for flexion and extension of the hip, pronation of the forearm, internal rotation of the shoulder, external and internal rotation of the knee, and dorsiflexion and plantarflexion of the ankle (p<0.05). Conclusions. As the result of this study, we conclude that when occlusal vertical dimension was increased, most of mean muscular strength values were increased. Especially at the position of 3.5mm increased vertical dimension displayed the highest mean muscular strength value than other positions.

연구목적 : 이 연구는 수직적 교합고경의 증가에 따른 사지 근력에 대한 영향을 관찰하고자 하였다. 연구재료 및 방법 : 평균 연령 21세의 10명의 남자를 선발하였다. 상악피개형의 교합장치를 제작하여 장치를 착용하지 않은 교두감합 (Intercuspal Position, ICP)시와 2mm, 3.5mm 그리고 5mm 수직적 교합고경을 증가시킨 위치에서 각각의 근력을 Cybex II dynamometer (Lumex Inc., Ronkonkoma, NY, USA)를 이용하여 측정하였다. 결과 : 측정한 14가지 동작 중 hip의 굴곡운동과 신전운동, forearm의 회외운동, shoulder의 내전운동, knee의 외전운동과 내전운동, ankle의 배측굴곡과 족측굴곡에서 교합장치의 장착시 근력의 유의한 증가를 보였다 (p<0.05). 결론 : 이 연구의 결과로 볼 때 수직적 교합고경을 증가시켰을 때 대부분의 동작에서 평균근력이 증가된다고 결론지을 수 있었다. 특히 3.5mm 수직적 교합고경을 증가시켰을 때 가장 높은 평균근력 증가율을 보였다.
