上颌前牙倾斜角度对种植治疗设计的影响

目的利用锥形束CT（CBCT）研究上颌前牙与牙槽骨的相对位置关系。方法选取上颌恒牙牙列完整的患者150例（年龄19-48岁，男性和女性各75例），按性别和牙位分为6个组。以牙槽骨长轴为基准，在CBCT影像上测量上颌前牙牙体长轴的相对倾斜角度（偏向腭侧为正，偏向唇侧为负）。使用SPSS19．0软件对数据进行统计分析。结果所有研究对象的上颌前牙的牙体长轴均偏向牙槽骨长轴的腭侧。男性上颌中切牙、侧切牙、尖牙的牙体长轴与牙槽骨长轴所成角度a的平均值分别为16．22°（2．50°-28．80°）、17．50°（3．80°-29．50°）、16．27°（1．00°～31．50°），而女性的相应测量结果平均...

Summary:目的利用锥形束CT（CBCT）研究上颌前牙与牙槽骨的相对位置关系。方法选取上颌恒牙牙列完整的患者150例（年龄19-48岁，男性和女性各75例），按性别和牙位分为6个组。以牙槽骨长轴为基准，在CBCT影像上测量上颌前牙牙体长轴的相对倾斜角度（偏向腭侧为正，偏向唇侧为负）。使用SPSS19．0软件对数据进行统计分析。结果所有研究对象的上颌前牙的牙体长轴均偏向牙槽骨长轴的腭侧。男性上颌中切牙、侧切牙、尖牙的牙体长轴与牙槽骨长轴所成角度a的平均值分别为16．22°（2．50°-28．80°）、17．50°（3．80°-29．50°）、16．27°（1．00°～31．50°），而女性的相应测量结果平均值分别为15．20°（2．20°～27．20°）、15．99°（4．10°-33．30°）、15．01°（3．50°-27．40°）。结论上颌前牙与牙槽骨的倾斜方向不一致，所有上颌前牙牙体长轴均偏向于牙槽骨长轴腭侧。通过CBCT观察上颌前牙与牙槽骨的位置关系，可以指导种植时机，种植体植入位置以及骨增量方案的选择。

Objective This study aims to analyze the angulation of the maxillary anterior teeth relative to the alveolus to provide reference data for clinicians on the best conditions for implant placement in the esthetic zone. Methods Numerous cone beam computed tomography （CBCT） images were reviewed and screened. A total of 150 maxillary images were selected by strict adherence to the defined inclusive criteria, with 75 images each from male and female patients （between the ages of 19 and 48 years at the time of CBCT scan）. The maxillary anterior teeth were gathered into the following three groups for males and females： upper canines, upper lateral incisors, and upper central incisors. Then, the long axis of each qualified tooth and its corresponding alveolar process were drawn, and the angles formed by these structures were measured. The resultant data were analyzed by SPSS 19.0.
