摘　　要：运用锥形束CT(CBCT)分析下颌颊棚区微种植体植入区域的解剖结构。收集86例患者CBCT资料三维重建。在下颌第一、二磨牙颊根的颊侧牙槽嵴顶下方选取3、6、9mm的断层,测量牙根表面到骨皮质表面的距离。应用SPSS21.0软件进行分析。左右两侧及男女各测量值差异均无统计学意义;测量点中骨厚度最大值为(9.17±1.93)mm,最小值为(0.96±0.48)mm。下颌颊棚区骨厚度有自牙合方向根方,自近中向远中增加的趋势,且个体差异较大。To evaluate the best implantation site of microscrews in buccal shelf area by using cone beam computer tomographic （CBCT） . The CBCT images of 86 patients were selected and used to reconstructe the three-dimensional computed tomographic images. Faultages of 3 ram,6 mm and 9 mm from the alveolar crest in the buccal shelf area （ the huccal side of the buccal root of the first molar and the second molar） were selected respectively to measure the thickness between the teeth root surface and the bony cortex surface. SPSS 21.0 software was used for statistical analysis. No statistically significant difference was found between left and right side, as well as male and female. The maximum value of bone thickness was （9.17 ± 1.93） mm,and the minimum value was （0.96±0.48） mm. The thickness of the mandibular buccal area had a tendency to increase from the occlusal direction to the root side, from near to middle, and there were individual difference.
