目的：了解上颌锥形侧切牙患者颅颌面形态特征。方法：纳入113例12～28岁的上颌锥形侧切牙患者，对其进行X线头影测量分析。结果：113例患者的矢状面型构成比为：Ⅰ类40．71％、Ⅱ类9．73％、Ⅲ类49．56％；垂直面型构成比为：均角型41．59％，高角型18．58％，低角型39．82％。SNA、ANB、Ptm-A（mm）、U1-SN、L1-NB、UL-EP值减小（P＜0．05），SNB、PP-GoGn、SN-MP、Y轴、U1-L1、U1-NA、L1-MP、Z角增大（P＜0．05）。结论：多数上颌锥形侧切牙患者颅颌面形态特征表现为上颌后缩，下颌前突，面中部软组织凹陷。
目的：瞭解上頜錐形側切牙患者顱頜麵形態特徵。方法：納入113例12～28歲的上頜錐形側切牙患者，對其進行X線頭影測量分析。結果：113例患者的矢狀麵型構成比為：Ⅰ類40．71％、Ⅱ類9．73％、Ⅲ類49．56％；垂直麵型構成比為：均角型41．59％，高角型18．58％，低角型39．82％。SNA、ANB、Ptm-A（mm）、U1-SN、L1-NB、UL-EP值減小（P＜0．05），SNB、PP-GoGn、SN-MP、Y軸、U1-L1、U1-NA、L1-MP、Z角增大（P＜0．05）。結論：多數上頜錐形側切牙患者顱頜麵形態特徵錶現為上頜後縮，下頜前突，麵中部軟組織凹陷。
목적：료해상합추형측절아환자로합면형태특정。방법：납입113례12～28세적상합추형측절아환자，대기진행X선두영측량분석。결과：113례환자적시상면형구성비위：Ⅰ류40．71％、Ⅱ류9．73％、Ⅲ류49．56％；수직면형구성비위：균각형41．59％，고각형18．58％，저각형39．82％。SNA、ANB、Ptm-A（mm）、U1-SN、L1-NB、UL-EP치감소（P＜0．05），SNB、PP-GoGn、SN-MP、Y축、U1-L1、U1-NA、L1-MP、Z각증대（P＜0．05）。결론：다수상합추형측절아환자로합면형태특정표현위상합후축，하합전돌，면중부연조직요함。
Objective:To analyze the craniofacial morphology characeristics of patients with peg-shaped upper lateral incisors. Methods:1 13 patients,aged 12 ~28 years,with peg-shaped upper lateral incisors were included,lateral cephalograms were taken and analyzed cephalometrically.Data were statistically analysed.Results:The sagittal facial patterns were skeletal Class Ⅰ(40.71%),skeletal Class Ⅱ(9.73%)and skeletal Class Ⅲ(49.56%).The vertical skeletal patterns were average vertical type (41.59%),high vertical type(18.58%)and low vertical type(39.82%).SNA,ANB,Ptm-A(mm),U1-SN,L1-NB,UL-EP were smaller(P<0.05)and SNB,PP-GoGn,SN-MP,Y axis,U1-L1,U1-NA,L1-MP and Z angles were increased(P<0.05).Conclu-sion:Patients with peg-shaped upper lateral incisors show Class Ⅲ skeletal pattern with maxillary retrognathia and mandibular prog-nathism.
