咀嚼系统是一个整体的功能单元,为各组成间相互协调而又彼此影响的统一体。(牙合)是口腔功能的关键,亦是口腔疾病诊断和修复的关键。修复体的(牙合)面形态,必须与下颌功能运动相协调。由于对(牙合)的认识不足,临床上往往造成治疗失败或因不适当的修复引起颞下颌关节功能紊乱。根据PMS学派的基本观点,修复休必须具备与患者下颌运动规迹相一致的协调的功能性(牙合)面。早在1932年Frederick就提 The chewing system is an integral functional unit, which is a unity of mutual coordination and influence each other. (Occlusion) is the key to oral function, but also the key to the diagnosis and repair of oral diseases. Restoration of the (occlusal) surface morphology, mandibular functional movement must be coordinated. Due to lack of understanding of (occlusion), clinically often result in treatment failure or improper repair caused by temporomandibular joint dysfunction. According to the PMS school's basic view, the repair must have a coordinated functional (occlusal) surface consistent with the patient's mandibular movement. As early as 1932, Frederick mentioned
