【摘要】：目的:分析偏侧咀嚼患者在最大张闭口运动中的下颌运动轨迹特征。方法:通过下颌运动轨迹描记检测技术,比较偏侧咀嚼和正常咀嚼人群在大张口运动中的运动轨迹,进行统计分析。结果:1)偏侧咀嚼组在大张口运动时开闭口轨迹多数分离,开口型与与双侧咀嚼组相比差异有统计学意义(P0.05)。2)偏侧咀嚼组张闭口运动时垂直向和矢状向位移显著低于双侧咀嚼组(P0.01)。结论:最大张闭口运动中偏侧咀嚼组开口型多数偏向工作侧,50%的人群开闭口轨迹分离,开口度减小,说明长期偏侧咀嚼会导致张闭口运动轨迹的异常。
[Abstract]:Objective: to analyze the characteristics of mandibular movement in patients with unilateral mastication during maximal open mouth movement. Methods: to compare the movement trajectory of unilateral masticatory and normal masticatory population in large open mouth movement by using the technique of mandibular movement locus recording. The results showed that most of the open and closed tracks of the unilateral mastication group were separated during the movement of the open mouth. The vertical and sagittal displacement in the unilateral mastication group was significantly lower than that in the bilateral masticatory group. Conclusion: the opening type of the unilateral masticatory group in the maximal tension closed movement is significantly lower than that in the bilateral masticatory group. Most of the population with 50% bias to the working side separated the locus of opening and closing, The decrease of opening degree indicates that long-term unilateral mastication will lead to the abnormal movement track of the closed mouth.
