摘要
目的:分析西安地区就诊Ⅲ类错颅面类型垂直向的构成。对临床制定合理的矫治方案提供一定的依据。方法:采用计算机辅助X线头影测量技术,对第四军医大学口腔医院正畸科2003~2008年就诊的Ⅲ类错患者的颅面类型进行回顾性研究,统计分析Ⅲ类错垂直向的构成。结果:替牙期就诊Ⅲ类患者垂直向主要表现为高角或均角,低角较为少见。在恒牙早期患者及恒牙期患者中垂直向主要表现为均角型(V2),低角型(V3)和高角型(V1)较少见。结论:西安地区就诊Ⅲ类错垂直向颅面类型在不同年龄段的构成存在一定差异,但总的来说均角(即垂直向发育正常)仍是各时期的主要表现形式。
Objective, To analyze the Xi'an class Ⅲmalocclusion vertical craniofacial type composition. Methods: From 2003-2008 in the Department of Orthodontics, the Fourth Military Medical University Dental Hospital, class Ⅲpermanent dentition malocclusion was studied, using computer--assisted cephalometric X technology, re- spectively. According to the vertical composition, the patients were divided into 3 groups, high-angle group (V1) both angle group (V2)low--angle group (V3). We analysed the class Ⅲatients with craniofacial morphology in the vertical composition, Results: The dentition in patients with skeletal class Ⅲwere vertical angle to the principal, or both for high: performance angle, and low angle was very rare. In the early permanent dentition and permanent dentition, both vertical angle (V2) was mainly, and low-- angle (V3) and high-- angle (V1) were relatively rare. Conclusion.. Among class Ⅲmalocclusion in Xi'an area, vertical craniofacial types in the composition of different a- ges were different, but in general; both angle was still the principal manifestation at each period.
