目的：探讨成人骨性Ⅱ类错患者是否适合通过内收上前牙掩饰治疗。方法2012-01~2013-09从沈阳市口腔医院预防科筛查出正常成人61例,同时从沈阳市口腔医院正畸科求治的成人病例中选取诊断为骨性Ⅱ类错畸形的患者61例,选取左上中切牙进行测量分析。以正常成人组为对照组,运用锥形束 CT( cone-beam computed tomography,CBCT)比较评估成人骨性Ⅱ类错上中切牙根尖区唇腭侧的牙槽骨厚度与个别正常成人上中切牙根尖区唇腭侧的牙槽骨厚度是否一致。使用 SPSS16.0软件包对数据进行统计学处理。结果成人骨性Ⅱ类错组患者上颌前牙根尖区唇侧牙槽骨厚度(P>0.05)、腭侧牙槽骨厚度(P>0.05)与正常成人上颌前牙根尖区唇腭侧牙槽骨厚度无统计学差异。结论骨性Ⅱ类错成人与正常成人唇腭侧牙槽骨厚度相似,提示成人骨性Ⅱ类错允许通过内收上前牙掩饰治疗。

Objective To evaluate the feasibility of camouflaged treatment by adduction of upper anterior tooth in patients with adult skeletal class Ⅱ malocclusion. Methods From January 2012 to September 2013,61 normal occlusion adult subjects were screened from Preventive Dentistry of Stomotology Hospital of Shenyang and 61 patients with skeletal classⅡmalocclusion( classⅡgroup) were selected in Orthodontic Department of Stomotology Hospital of Shenyang. Maxillary left central incisor of each subject was chosen for measurement. The cone-beam computed tomography was used to measure the thickness of the labial(L1),palatal(L2)alveolar bone. The results were compared between adult skeletal class Ⅱ patients and normal controls. Data were processed with SPSS16. 0 software package. Results The thickness of labial,palatal alveolar bone in patients with skeletal classⅡmalocclusion was similar to those of the normal controls(P>0. 05). Conclusion Skeletal class Ⅱ malocclusion patients exhibits similar labial and palatal alveolar bone thickness with individual normal occlusion controls, which suggests that it is feasible for adult patients with skeletal classⅡmalocclu-sion to perform camouflaged treatment by adduction of upper anterior tooth.
