摘要: 目的:使用CBCT三维定位分析54颗青少年上颌埋伏阻生牙,为正畸诊疗设计提供精准依据。方法:采用CBCT技术重建54颗青少年上颌埋伏阻生牙,应用CS 3D Imaging软件分析阻生牙位置、牙根情况及与邻牙关系进行测量分析并评价。结果:上颌埋伏阻生牙主要以垂直阻生为主,埋伏高度以牙冠位于邻牙根1/2至根尖占到66.7%;根尖位置以偏于10 mm以内居多;牙骨性粘连占1.9%。最终对54颗埋伏阻生牙牵引45颗,拔除9颗。结论:CBCT可精准三维定位埋伏阻生牙,为正畸临床治疗提供重要依据。

Abstract: Objective: To provide accurate guidline for clinical diagnosis and treatment design by analyzing 54 maxillary impacted teeth with CBCT three-dimensional technique. Methods: 54 maxillary impacted teeth were three-dimensional reconstructed by the use of CBCT technique. Their direction, position, root conditions and relationship with adjacent teeth were evaluated by CS 3D Imaging analysis software. Results: Maxillary impacted teeth were mostly vertical impacted and crowns were approximately near 1/2 or apex of adjacent teeth root in proportion of 66.7%. The position of the root apex varied in 10 millimeters ranges. The frequency of osseous adhesion was 1.9%. Of 54 maxillary impacted teeth, 45 were erupted by orthodontic traction and 9 were extracted. Conclusion: CBCT can locate impacted teeth precisely and provide an important basis for clinical orthodontic treatment.
