objective:to study character mandibular movement tracings during mandibular protrusion in patients with unilateral posterior crossbite and compare the difference with normal occlusion.
目的:探讨单侧后牙反牙合髁突前伸运动轨迹的特征并比较与正常牙合之间的差异。
mandibular movement is a kind of complex spacial three dimensional movement which is the result of contractions of active masticatory muscles and guided by the occlusion and temporomandibular joints.
下颌运动是在牙合、咀嚼肌及颞下颌关节共同参与下进行的一种复杂的三维运动,对下颌运动的研究是通过下颌运动轨迹描记仪进行的。
objective: to evaluate the mandibular movement after vertical dimension increasing.
目的:评价行垂直距离升高修复后下颌运动功能的变化。
