中文摘要
目的明确下颌处于不同矢状向位置时的牙形态，以及下颌矢状向位置与平面倾斜度的关系，为下颌矢状向位置异常患者的非手术正畸治疗提供策略依据。方法选取114例女性正畸患者治疗前的114张头影侧位片，根据ANB角的大小分为3组，每组各测量25项指标。对3组之间及两两组之间的差异进行方差分析和多重比较分析，对骨性指标与牙性指标的相关性进行直线相关分析。结果后牙平面（OP-P）倾斜度和上颌第二磨牙的垂直高度与下颌矢状向位置相关（P
英文摘要
Objective To investigate the relationship between occlusal plane and sagittal position of the mandible by examining dental and skeletal morphologies of average angle patients for better understanding of etiologies and definitive clinical guidelines of mandibular malpositions. Methods The lateral cephalograms of 114 female average angle patients with neutral maxillary positions were selected and divided into three groups according to sagittal mandibular positions（ANB angle）. Twenty-five skeletal and dental measurements were compared. The correlations between skeletal and dental measurements were analyzed by rectilinear correlation. Results Cant of posterior occlusal plane（OP-P） and height of the upper second molar were significantly related to sagittal position of the mandible（P
