【目的】比较前牵引(FM )与前牵引联合上颌快速扩弓(RM E)对青少年Ⅲ类错牙合患者牙颌矫治效果的影响。【方法】35例上颌发育不足的青少年Ⅲ类错牙合患者分别进行单纯前牵引(FM组,13例)及前牵引联合上颌快速扩弓(FM+RM E组,22例)矫治。通过测量矫治前后头颅定位侧位片8个角度和8条线距,比较两种矫治方法对牙颌矫治的疗效。【结果】两组矫治前各个角度和线距测量值比较无统计学差异( P >0.05);FM 组矫治后PP‐SN角、Co‐Gn距和Go‐Me距与矫治前比较无统计学差异( P >0.05),其余各角度和线距矫治前后的比较均有统计学差异( P<0.05)。FM+RME组矫治前后PP‐SN角、U1‐SN角、Co‐Gn距和Go‐Me距比较无统计学差异( P >0.05);其余各角和线距测量值矫治前后的比较均有统计学差异( P <0.05)。组间比较:FM 组上前牙(U1‐SN角)发生了更多的唇倾,而FM+RM E组上颌骨更多的发生了前移(Wits值),其余各值在两组间无统计学差异( P >0.05)。【结论】FM 可使上颌骨前移,下颌骨产生顺时针旋转,而FM+RM E疗效更明显。
【目的】比較前牽引(FM )與前牽引聯閤上頜快速擴弓(RM E)對青少年Ⅲ類錯牙閤患者牙頜矯治效果的影響。【方法】35例上頜髮育不足的青少年Ⅲ類錯牙閤患者分彆進行單純前牽引(FM組,13例)及前牽引聯閤上頜快速擴弓(FM+RM E組,22例)矯治。通過測量矯治前後頭顱定位側位片8箇角度和8條線距,比較兩種矯治方法對牙頜矯治的療效。【結果】兩組矯治前各箇角度和線距測量值比較無統計學差異( P >0.05);FM 組矯治後PP‐SN角、Co‐Gn距和Go‐Me距與矯治前比較無統計學差異( P >0.05),其餘各角度和線距矯治前後的比較均有統計學差異( P<0.05)。FM+RME組矯治前後PP‐SN角、U1‐SN角、Co‐Gn距和Go‐Me距比較無統計學差異( P >0.05);其餘各角和線距測量值矯治前後的比較均有統計學差異( P <0.05)。組間比較:FM 組上前牙(U1‐SN角)髮生瞭更多的脣傾,而FM+RM E組上頜骨更多的髮生瞭前移(Wits值),其餘各值在兩組間無統計學差異( P >0.05)。【結論】FM 可使上頜骨前移,下頜骨產生順時針鏇轉,而FM+RM E療效更明顯。

[Objective] To compare the skeletal and dental outcomes of face mask (FM)with and without rapid maxillary expansion (RME) in adolescents with maxillary retrognathia .[Methods] There were 16 males and 19 females with an age range of 8~13 years .Pretreatment and posttreatment cephalometric radiographs were ana‐lyzed for skeletal class Ⅲ malocclusion .They were divided into two groups of FM alone ( n =13) and FM plus RME ( n=22) .Eight cephalometric linear and eight angular variables were measured to assess the skeletal and dental changes .Within‐group and between‐group comparisons were determined by paired t‐test .[Results] For‐ward displacement of maxilla and clockwise rotation of mandible occurred in two groups .The maxillary‐mandibular relationship existed .Most indices presented statistical significance within group .However ,only U1‐SN and Wits were different between groups .[Conclusion] Forward movement of maxilla and clockwise rotation of mandible may be obtained in adolescents after face masking .Yet RME can further improve the treatment outcomes .
