【摘要】：目的:通過對珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者拔牙矯治前后頭顱側(cè)位片進行測量分析,總結(jié)該類患者矯治的特點,為當?shù)卦擃惢颊叩某C治方案設(shè)計、治療及預后評估提供參考依據(jù)。方法:從2011年7月~2015年10月就診于遵義醫(yī)學院第五附屬(珠海)醫(yī)院口腔科的正畸患者中篩選出符合納入標準的成人AngleⅡ~1類(骨性)錯（牙合）拔牙患者44例;男:18例,女:26例,平均年齡20.75±2.36歲,平均療程27.70±3.75月。對所有患者矯治前后頭顱側(cè)位片進行計算機頭影測量軟件AngelCeph8.0繪圖分析,均用McNamara和Steiner分析方法輸出共24項軟硬組織測量數(shù)據(jù)。計量資料運用t檢驗,分別與廣東正常（牙合）(男、女)以及國人正常（牙合）進行Steiner分析方法對比分析,矯治前后對比用McNamara和Steiner分析方法,從矯治前后對比中篩選出矯治前后變化有統(tǒng)計學意義(P0.05:有統(tǒng)計學差異)的指標,并對對比結(jié)果進行綜合分析,總結(jié)出珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者拔牙矯治前后的特點。結(jié)果:1、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者矯治前與廣東正常（牙合）比較:男女患者ANB角、UI-NA角、GoGN-SN角均較大(P0.05);SNB角、SND角、UI-LI角、SL距、SE距均較小(P0.05)。2、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者矯治后與廣東正常（牙合）比較:男女患者UI-LI角、GoGN-SN角均較大(P0.05);女性患者ANB角較大(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距均較小(P0.05)。3、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者矯治前與國人正常（牙合）比較:ANB角、UI-NA角、Ls-EP距、Li-EP距、SE距較大(P0.05);SNB角、SND角、Pg-NB距、UI-LI角、SL距均較小(P0.05)。4、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者矯治后與國人正常（牙合）比較:ANB角、Ls-EP距、Li-EP距、SE距、OP-SN角、UI-LI角均較大(P0.05);SNB角、SND角、UI-NA距、Pg-NB距、SL距、UI-NA角較小(P0.05)。5、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者矯治前后比較:有效下頜長度Co-Gn距、上下中切牙夾角UI-LI角均增大、面下1/3長度ANS-Me距、（牙合）平面角OP-SN角增大(P0.05);上頜突度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、上切牙唇傾角UI-NA角、上唇突距Ls-EP距、下唇突距Li-EP距均顯著減小(P0.05)。結(jié)論:1、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者拔牙矯治后未達到廣東正常（牙合）和國人正常（牙合）標準,但軟硬組織改善幅度較大,符合掩飾治療目的。2、矯治前后有統(tǒng)計學意義的指標(見附圖)可為珠海籍成人AngleⅡ~1類(骨性)錯（牙合）拔牙矯治患者制定矯治方案及預后評估提供參考。3、珠海籍成人AngleⅡ~1類(骨性)錯（牙合）患者與廣東AngleⅡ~1患者臨床特征及發(fā)病機制相似,頭影測量分析時建議結(jié)合國人正常（牙合）與廣東正常（牙合）參考值作為參考。
[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.
