Abstract:

Canted occlusal plane is the main feature of mandibular deviation. The causes of occlusal plane canting are very complicated and inconclusive. A large number of studies have shown that it is related to bite force，bite contact area，chewing movement and even head or neck position. CBCT is the best diagnostic method for assessing occlusal plane canting at present. Canted occlusal plane and mandibular deviation are mainly ipsilateral，and a small number reveals contralateral. It can also have adverse effects on temporomandibular joint and mastication，and it has been difficult to be corrected with non-surgical methods. Based on the existing literature，we summarized the canted occlusal plane features，adverse effects and the commonly used non-surgical treatment methods.

摘要：

牙合平面偏斜是下颌偏斜的主要特征，其形成原因较为复杂且目前尚无定论。研究表明，牙合平面偏斜与咬合力、咬合接触面积、咀嚼运动，甚至头颈姿势位有关。锥形束CT（CBCT）是目前评估牙合平面偏斜程度的最佳诊断方法。常见牙合平面偏斜与下颌偏斜关系主要为同侧偏斜，也有少部分患者为对侧偏斜，可对颞下颌关节及咀嚼运动造成不良影响。临床上非手术纠正牙合平面偏斜一直是治疗难点。文章根据现有文献，对牙合平面偏斜特征及不良影响进行梳理，并针对临床常用的非手术治疗方法进行归纳综述。
