目的 分析骨性Ⅲ类错(牙合)手术患者上下颌前牙的代偿特征,以期为临床提供患者术前牙颌代偿的数据参考.方法 选取2011年11月至2015年1月于北京大学口腔医学院·口腔医院进行正畸-正颌联合治疗的54例成年骨性Ⅲ类错(牙合)患者,取治疗前头颅侧位X线片,进行头影测量,并与北京大学口腔医学院·口腔医院建立的中国汉族正常(牙合)相应数据进行单样本t检验;对患者骨性测量项目与牙性测量项目进行Pearson相关性分析;根据颌骨矢状向和垂直向关系将患者分成4组,A组:ANB角＜-4°,SN-MP角≤37.7°,11例;B组:ANB角≥-4°,SN-MP角≤37.7°,16例;C组:ANB角＜-4°,SN-MP角＞37.7°,14例;D组:ANB角≥-4°,SN-MP角＞37.7°,13例.对4组牙颌测量项目进行单因素方差分析和SNK法多重比较.结果 骨性Ⅲ类错(牙合)上前牙较正常(牙合)更唇倾(P＜0.01),下前牙较正常(牙合)更舌倾(P＜0.01).矢状向和垂直向骨型均与上下前牙位置有一定相关性(P＜0.05).4组患者上切牙倾斜度及突度代偿差异均无统计学意义(P＞0.05);A组下切牙舌倾及舌向移位代偿最明显[L1-NB角、L1-NB距分别为(14.2°±5.9°)和(2.2±1.9) mm],而D组代偿最轻[L1-NB角、L1-NB距分别为(23.7°±7.5°)和(6.3±2.6)mm].结论 骨性Ⅲ类错(牙合)上前牙唇倾代偿,下前牙舌倾代偿;不同骨面型上下前牙的代偿特征各有不同,去代偿时应区别处理.
目的 分析骨性Ⅲ類錯(牙閤)手術患者上下頜前牙的代償特徵,以期為臨床提供患者術前牙頜代償的數據參攷.方法 選取2011年11月至2015年1月于北京大學口腔醫學院·口腔醫院進行正畸-正頜聯閤治療的54例成年骨性Ⅲ類錯(牙閤)患者,取治療前頭顱側位X線片,進行頭影測量,併與北京大學口腔醫學院·口腔醫院建立的中國漢族正常(牙閤)相應數據進行單樣本t檢驗;對患者骨性測量項目與牙性測量項目進行Pearson相關性分析;根據頜骨矢狀嚮和垂直嚮關繫將患者分成4組,A組:ANB角＜-4°,SN-MP角≤37.7°,11例;B組:ANB角≥-4°,SN-MP角≤37.7°,16例;C組:ANB角＜-4°,SN-MP角＞37.7°,14例;D組:ANB角≥-4°,SN-MP角＞37.7°,13例.對4組牙頜測量項目進行單因素方差分析和SNK法多重比較.結果 骨性Ⅲ類錯(牙閤)上前牙較正常(牙閤)更脣傾(P＜0.01),下前牙較正常(牙閤)更舌傾(P＜0.01).矢狀嚮和垂直嚮骨型均與上下前牙位置有一定相關性(P＜0.05).4組患者上切牙傾斜度及突度代償差異均無統計學意義(P＞0.05);A組下切牙舌傾及舌嚮移位代償最明顯[L1-NB角、L1-NB距分彆為(14.2°±5.9°)和(2.2±1.9) mm],而D組代償最輕[L1-NB角、L1-NB距分彆為(23.7°±7.5°)和(6.3±2.6)mm].結論 骨性Ⅲ類錯(牙閤)上前牙脣傾代償,下前牙舌傾代償;不同骨麵型上下前牙的代償特徵各有不同,去代償時應區彆處理.

Objective To investigate the compensation of the upper and lower incisors in skeletal Class Ⅲ patients treated with orthodontic-surgical approach.Methods The samples consisted of 54 skeletal Class Ⅲ patients treated with orthodontic-surgical approach from November 2011 to January 2015.Lateral cephalograms were taken before treatment.The differences between the samples and the norms from Peking University normal occlusion sample library were assessed using independent-sample t test.Correlation analyses were performed to find associations between skeletal and dental parameters.According to skeletal anteroposterior discrepancy/vertical type (ANB/SN-MP), the samples were allocated into group A (ANB＜-4°, SN-MP≤37.7°, n=1 1), group B (ANB≥-4°, SN-MP≤37.7°, n=16), group C (ANB＜-4°, SN-MP＞ 37.7°, n=14), and group D(ANB≥-4°, SN-MP＞37.7°, n=13).After measurement of variables, one-way ANOVA with SNK multiple comparison test were performed.Results The maxillary incisors were more proclined and the mandibular incisors more retroclined in skeletal Class Ⅲ patients compared with norm values(P＜0.01).Both skeletal anteroposterior discrepancy and vertical type were correlated with the position of upper and lower incisors(P＜0.01).According to skeletal anteroposterior discrepancy/vertical type, no significant differences were found in the upper incisors' inclination among the four groups, while patients in group A and group D exhibited significant difference in lower incisor compensation.Conclusions Different skeletal anteroposterior discrepancy/vertical type resulted in varied incisors' compensation.Therefore,decompensation should be treated differently.
