摘要/Abstract

摘要： 目的:探讨双颌前突患者矫治前后软组织的三维变化。方法:选取双颌前突成人患者24例,分别在治疗前后拍摄头颅侧位片和三维扫描,测量27个软组织项目。所有结果采用配对t检验。结果:上切牙内收6.12 mm,下切牙内收4.58 mm,上唇显著后移,而下唇显著向上向后移动。唇和切牙内收比率在上颌约为52%,下颌约为82%。结论:三维扫描可以有效的反应软组织变化。双颌前突患者的上下唇显著向后移动。

Abstract: Objective: To evaluate the three-dimensional (3D) perioral soft tissue changes after orthodontic treatment in patients with bi-maxillary protrusion using light-based scanners. Methods: Twenty-four adults with bi-maxillary protrusion were treated by extraction of four first premolars. Lateral cephalograms and 3D facial scans were obtained before treatment (T1) and immediately after debonding (T2). Superimposition was performed, and 27 perioral landmarks were identified. Paired student t-test and one-way analysis of variance were performed. Results: The mean retraction distances of the upper and lower incisors were 6.12 mm and 4.58 mm, respectively. The upper lip moved inferoposteriorly, and the lower lip moved superoposteriorly. The relative ratios were 42%-53% in the upper and 22%-82% in the lower. The lip corners moved superoposteriorly. Conclusion: Facial scanning by white structured light scanners can efficiently evaluate 3D perioral soft tissue changes in bi-maxillary protrusion patients. Obvious backward movement of the upper and lower lips was observed.
