| 目的 通过对拔牙掩饰性治疗骨性Ⅱ类错颌上前牙唇侧骨量进行测量分析，评价其骨开窗和骨开裂的风险。方法 对15名接受拔牙治疗的骨性Ⅱ类成人患者行锥形束CT扫描及三维重建，测量上前牙唇侧牙槽嵴顶距釉牙骨质界距离D和骨开窗高度F。结果 术前D值为（1.61±0.75）mm，术后为（1.70±0.76）mm，术后D值略有增大，但两者差异无统计学意义（P>0.05）；术前F值为（0.23±0.76）mm，术后为（0.023±0.14）mm，术后F值减小，两者差异也无统计学意义（P>0.05）。结论 骨性Ⅱ类拔牙掩饰性治疗不会加重上前牙唇侧骨开窗及骨开裂的发生。 |

| Objective The aim of this study was to assess the risk of dehiscence and fenestration of upper anterior teeth of the skeletal class Ⅱ patients with camouflage orthodontic treatment by the measurement of the labial bones. Methods Cone-beam computed tomography and 3D reconstruction were used for 15 adult patients of class Ⅱ malocclusion who accepted the camouflage treatment, and the distances between enamelocemental junction (D) and alveolar crest and the fenestration height (F) were measured respectively. Result The D valueincreased from 1.61±0.75 mm before the treatment to1.70±0.76 mm after the treatment. The F value decreased from 0.23±0.76 mm before the treatment to 0.023±0.14 mm after the treatment. However, there were no statistically significant differences between both groups (P>0.05). Conclusion Camouflage orthodontic treatment for the skeletal class Ⅱ patients will not worsen the dehiscence and fenestration of upper anterior teeth. |
