下颌前牙与牙槽骨的位置关系对种植治疗设计的影响
目的利用锥形束CT(CBCT)研究正中矢状面下颌前牙与牙槽骨的相对位置关系,为下颌前牙区的种植修复设计提供参考。方法从CBCT影像库中选取下颌恒牙列完整的影像学资料150例,按照性别、牙位分为6组,以受测牙正中矢状面的牙槽骨长轴为基准,测量下颌前牙牙体长轴相对于牙槽骨长轴的倾斜角度(偏舌侧为正,偏唇侧为负)。使用SPSS19.0软件对数据进行统计学分析。结果男性下颌中切牙、下颌侧切牙、下颌尖牙牙体长轴相对于牙槽骨长轴倾斜角度的平均值分别为4.77°(-8.17°-16.10°)、6.12°(-2.87°-17.57°)、5.01°(-8.13°-17.67°),女性倾斜角度的平均值依次为5.3...

Summary: | 目的利用锥形束CT(CBCT)研究正中矢状面下颌前牙与牙槽骨的相对位置关系,为下颌前牙区的种植修复设计提供参考。方法从CBCT影像库中选取下颌恒牙列完整的影像学资料150例,按照性别、牙位分为6组,以受测牙正中矢状面的牙槽骨长轴为基准,测量下颌前牙牙体长轴相对于牙槽骨长轴的倾斜角度(偏舌侧为正,偏唇侧为负)。使用SPSS19.0软件对数据进行统计学分析。结果男性下颌中切牙、下颌侧切牙、下颌尖牙牙体长轴相对于牙槽骨长轴倾斜角度的平均值分别为4.77°(-8.17°-16.10°)、6.12°(-2.87°-17.57°)、5.01°(-8.13°-17.67°),女性倾斜角度的平均值依次为5.38°(-5.63°-12.93°)、5.81°(-7.70°-15.70°)、6.21°(-7.70°-17.87°)。其中,男性下颌中切牙、下颌侧切牙、下颌尖牙倾斜角度在-10°~10°区间的百分比依次为87.34%、80.67%、88.00%,女性依次为90.67%、82.66%、82.66%。无论男性还是女性,下颌前牙牙体长轴相对于牙槽骨长轴倾斜角度在(-10°~10°)的百分比均超过80%,且牙体长轴偏向唇侧均不超过10°,偏向舌侧均不超过20°。结论绝大多数下颌前牙牙体长轴与牙槽骨长轴的方向基本一致,临床上可以参考二者的位置关系制定合理的种植治疗方案。 |

Bibliography: | 51-1169/R the mandibular anterior; the long axis of the tooth; the long axis of the alveolar bone; the median sagittal plane Objective This study aimed at investigating and measuring the positional relationship between the long axis of the mandibular anterior teeth and the alveolar bone using cone beam computed tomography (CBCT) to provide reference data for implant treatment. Methods Fromthe CBCT image database, 150 cases of radiographic data were selected according to the inclusion criteria and then were divided into six groups: males' mandibular central incisors, males' mandibular lateral incisors, males' mandibular canines, females' mandibular central incisors, females' mandibular lateral incisors, and females' mandibular canines. The angle (13) formed by the long axis of the mandibular anterior teeth and the corresponding alveolar bone was measured and recorded. Based on the long axis of alveolar bone, if the teeth incline to the lingual side, the value of the angle (13) was positive; otherwise, the value |
