摘要/Abstract

摘要： 目的对汉族正常青年人上前牙区不同位点的唇、腭侧牙槽骨厚度进行测量,为术前评估、治疗方案制定及预后评估提供参考。方法通过锥形束CT（CBCT）对67名符合条件的汉族青年志愿者进行上颌骨扫描。三维重建后,对前牙区唇、腭侧骨厚度进行测量。利用SPSS17.0软件包对测量数据进行配对t检验、独立样本t检验、方差分析及χ²检验。结果①唇侧骨板除所有前牙L5处及上颌尖牙L1处厚度均数>1.00 mm外,其余测量位点唇侧骨板厚度均数均<1.00mm,而腭侧骨板厚度均数均>1.00 mm;② 唇侧骨板厚度均小于腭侧骨板厚度（P<0.001）;③3种前牙唇侧骨板厚度在参考线L3与L4处厚度最小（P<0.001）,腭侧骨板厚度自L1至L5逐渐增大（P<0.05）;④ 仅在上颌尖牙L2处及所有前牙L5处唇侧骨板厚度<1.00 mm的频率<50%,男性上颌侧切牙L3、L4处及上颌尖牙L4处唇侧骨板缺如所占频率>50%;⑤男性切牙区唇侧骨板凹陷角度较尖牙小（P<0.05）,唇侧骨板最凹点与根尖点之间的距离在男性上颌中切牙最大（P<0.05）,女性牙位间无显著差异。结论正常青年人上前牙牙槽骨骨板菲薄甚至缺如,且唇、腭侧骨厚度和形态存在差异。

Abstract: PURPOSE: To investigate the labial and palatal bone thickness of the maxillary anterior teeth in normal young adults on different reference lines, in order to provide references for clinical treatment. METHODS: Sixty-seven eligible Han nationality young volunteers were scanned by cone-beam computed tomography (CBCT). The labial and palatal bone thickness and the labial bone morphology of the anterior teeth were measured after reconstruction. Paired-sample t test, independent- sample t test, one-way ANOVA and Chi-square test were performed using SPSS17.0 software package. RESULTS: ①The mean labial bone thicknesses at L1 of canines and L5 of all anterior teeth were more than 1.00 mm, while the thickness of the other labial measurement sites were less than 1.00 mm. The mean palatal bone thickness was more than 1.00 mm. ② The labial bone was thinner than the palatal bone (P<0.001). ③The labial bone was the thinnest at L3 and L4 of the anterior teeth（P<0.001). The thickness of palatal bone gradually increased from the L1 to L5(P<0.001). ④ The frequency of the labial bone thinner than 1.00 mm was less than 50% at L2 of canines and L5 of all anterior teeth; The frequency of the labial bone deficiency at L3 and L4 of lateral incisors and L4 of canines was more than 50% in males. ⑤The mean buccal bony curvature of canines was larger than that of incisors in males. The distance between root apex and the deepest point of buccal bony curvature was the largest in maxillary central incisors zone in males, while there was no significant difference in females. CONCLUSIONS: The alveolar bone thickness of the maxillary anterior teeth in normal young adults are quite thin or even deficient, and there is diversity of the thickness and morphology between labial and palatal bone.
