众所周知,下颌生理运动极为复杂,但仍可归纳为三种基本形式:即开闭运动、前后运动及侧方运动。在这三种基本生理运动形式中,以开口运动中的最大开口时,下颌骨髁状突的向前生理运动范围最广。传统的观点认为:在最大开口时,髁状突皆同关节盘运动至关节结节的下方或稍前下方而不超过。但当翼外肌功能紊乱或关节结构病变时,在开口末,翼外肌再继续收缩以至
As we all know, the physiological activities of the jaw is extremely complicated, but still can be summarized into three basic forms: the opening and closing movement, before and after exercise and lateral movement. In these three basic physiological forms of exercise, the maximal opening in the mandibular condyle has the widest range of forward physiological motions. The traditional view that: the maximum opening, the condyles with the articular disc movement to the joint nodules below or slightly below and below. However, when the wing outside the muscle dysfunction or joint structure lesions, at the end of the opening, the wing outside the muscle to continue to shrink and even
