【摘要】：目的:通过对珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者拔牙矫治前后头颅侧位片进行测量分析,总结该类患者矫治的特点,为当地该类患者的矫治方案设计、治疗及预后评估提供参考依据。方法:从2011年7月~2015年10月就诊于遵义医学院第五附属(珠海)医院口腔科的正畸患者中筛选出符合纳入标准的成人AngleⅡ~1类(骨性)错（牙合）拔牙患者44例;男:18例,女:26例,平均年龄20.75±2.36岁,平均疗程27.70±3.75月。对所有患者矫治前后头颅侧位片进行计算机头影测量软件AngelCeph8.0绘图分析,均用McNamara和Steiner分析方法输出共24项软硬组织测量数据。计量资料运用t检验,分别与广东正常（牙合）(男、女)以及国人正常（牙合）进行Steiner分析方法对比分析,矫治前后对比用McNamara和Steiner分析方法,从矫治前后对比中筛选出矫治前后变化有统计学意义(P0.05:有统计学差异)的指标,并对对比结果进行综合分析,总结出珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者拔牙矫治前后的特点。结果:1、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者矫治前与广东正常（牙合）比较:男女患者ANB角、UI-NA角、GoGN-SN角均较大(P0.05);SNB角、SND角、UI-LI角、SL距、SE距均较小(P0.05)。2、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者矫治后与广东正常（牙合）比较:男女患者UI-LI角、GoGN-SN角均较大(P0.05);女性患者ANB角较大(P0.05),男性患者ANB角正常(P0.05)。男女患者SNA角、SNB角、SND角、UI-LI距、SL距、SE距均较小(P0.05)。3、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者矫治前与国人正常（牙合）比较:ANB角、UI-NA角、Ls-EP距、Li-EP距、SE距较大(P0.05);SNB角、SND角、Pg-NB距、UI-LI角、SL距均较小(P0.05)。4、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者矫治后与国人正常（牙合）比较:ANB角、Ls-EP距、Li-EP距、SE距、OP-SN角、UI-LI角均较大(P0.05);SNB角、SND角、UI-NA距、Pg-NB距、SL距、UI-NA角较小(P0.05)。5、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者矫治前后比较:有效下颌长度Co-Gn距、上下中切牙夹角UI-LI角均增大、面下1/3长度ANS-Me距、（牙合）平面角OP-SN角增大(P0.05);上颌突度A-Np距、上切牙突距UI-AP距、下切牙突距LI-A-Pog距、SNA角、ANB角、上切牙突距UI-NA距、上切牙唇倾角UI-NA角、上唇突距Ls-EP距、下唇突距Li-EP距均显著减小(P0.05)。结论:1、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者拔牙矫治后未达到广东正常（牙合）和国人正常（牙合）标准,但软硬组织改善幅度较大,符合掩饰治疗目的。2、矫治前后有统计学意义的指标(见附图)可为珠海籍成人AngleⅡ~1类(骨性)错（牙合）拔牙矫治患者制定矫治方案及预后评估提供参考。3、珠海籍成人AngleⅡ~1类(骨性)错（牙合）患者与广东AngleⅡ~1患者临床特征及发病机制相似,头影测量分析时建议结合国人正常（牙合）与广东正常（牙合）参考值作为参考。
[Abstract]:Objective: to measure and analyze the lateral cephalometric slice of the patients with Angle II ~1 class (skeletal) malocclusion before and after orthodontic treatment in Zhuhai, and to summarize the characteristics of this kind of orthodontic treatment, so as to provide reference for the design, treatment and prognosis evaluation of the local patients. Methods: from July 2011 October ~2015 in Zunyi Medical College Hospital Affiliated fifth (Zhuhai) were selected in accordance with the inclusion criteria of the ~1 class Angle adult orthodontic patients in hospital department of Stomatology (OA) wrong (occlusal) in 44 cases of patients undergoing tooth extraction; male: 18 cases, female 26 cases, mean age 20.75 + 2.36 years old, the average course of treatment 27.70 + 3.75 months. The cephalometric lateral slices of all patients before and after orthodontic treatment were analyzed by cephalometric analysis software AngelCeph8.0, and 24 soft and hard tissue measurement data were output by McNamara and Steiner analysis. Measurement data using t test, normal and Guangdong respectively (occlusal) (male and female) and Chinese normal (occlusal) analysis were compared before and after treatment compared with Steiner, McNamara and Steiner analysis method, from the comparison before and after treatment were statistically significant changes before and after treatment (P0.05: significant difference). The index, and a comprehensive analysis of the results, summed up the Zhuhai province adult Angle II ~1 (bony) wrong (occlusal) characteristics of patients before and after extraction treatment. Results: 1. Compared with orthodontic treatment in Zhuhai adult Angle class II (~1), the ANB angle, UI-NA angle and GoGN-SN angle were significantly higher than those in Guangdong (P0.05). SNB angle, SND angle, UI-LI angle, SL distance and SE distance were all smaller (UI-LI). 2, Zhuhai adult Angle II ~1 class (skeletal) malocclusion patients after orthodontic treatment and Guangdong normal occlusion: male and female patients UI-LI angle and GoGN-SN angle are larger (P0.05); female patients with larger ANB angle (P0.05), male patients ANB angle is normal (P0.05). The SNA angle, SNB angle, SND angle, UI-LI distance, SL distance and SE distance were smaller in male and female patients (P0.05). 3, Zhuhai adult Angle II ~1 class (skeletal) malocclusion patients before orthodontic treatment compared with Chinese normal occlusion: ANB angle, UI-NA angle, Ls-EP distance, Li-EP distance and SE distance were larger (P0.05); SNB angle, SND angle, Pg-NB distance, angle of fire and distance between them were all smaller. 4, Zhuhai province adult Angle II ~1 (bony) wrong (occlusal) patients after treatment with Chinese normal (occlusal) comparison: ANB angle, Ls-EP distance, Li-EP distance, SE distance, OP-SN angle and UI-LI angle were larger (P0.05); SNB angle, SND angle, UI-NA distance, Pg-NB distance SL distance and UI-NA angle (P0.05). 5, Zhuhai province adult Angle II ~1 (bony) wrong (occlusal) patients before and after treatment, the effective mandibular length Co-Gn from the upper and lower incisor angle UI-LI angle increased, the length of 1/3 ANS-Me from the surface, (occlusal) plane angle OP-SN angle (P0.05); maxillary protrusion distance, A-Np the upper incisor protrusion distance UI-AP distance, lower incisor protrusion distance LI-A-Pog distance, SNA angle, ANB angle, upper incisor protrusion distance UI-NA distance, the upper incisor lip inclination angle, the upper lip protrusion distance UI-NA Ls-EP distance and li-e were significantly reduced from Li-EP (P0.05). Conclusion: 1. In Zhuhai adults, Angle class II ~1 class (skeletal) malocclusion patients did not achieve the standard of normal occlusion or normal occlusion after orthodontic treatment, but the improvement of soft and hard tissues was larger than those of adults in Guangdong. 2, statistically significant indicators before and after orthodontic treatment (see attached drawings) can provide reference for developing orthodontic treatment and prognosis evaluation of adult Angle II ~1 class (skeletal) malocclusion patients in Zhuhai. 3, Zhuhai adults Angle II ~1 class (skeletal) malocclusion patients and Guangdong Angle II ~1 patients with similar clinical characteristics and pathogenesis. Cephalometric analysis suggested that the reference value of Chinese normal occlusion and Guangdong normal occlusion as a reference.
