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...

| Abstract_FL | 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.Results The long axis of the maxillary anterior teeth all inclined to the palatal side of the alveolar process. The internal angle (α) formed by the long axis of the maxillary central incisors and the long axis of the alveolar bone presented a mean value of 16.22° (range: 2.50°-28.80°) for male subjects and 15.20° (range: 2.20°-27.20°) for female subjects. The internal angle (α) of the maxillary lateral incisors exhibited a mean value of 17.50° (range: 3.80°-29.50°) for male subjects and 15.99° (range: 4.10°-33.30°) for female subjects. Finally, the internal angle (α) of the maxillary canines presented a mean value of 16.27° (range: 1.00°-31.50°) for male subjects and 15.01° (range: 3.50°-27.40°) for female subjects. Conclusion The long axis of the maxillary anterior teeth all inclined to the palatal side of the alveolar process. For implant placement, careful preoperative analysis and evaluation with CBCT may be beneficial for avoiding the risk factors and achieving a high probability of success in the esthetic region. |
