摘　　要：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。Objective：To analyze the craniofacial morphology characeristics of patients with peg-shaped upper lateral incisors. Methods：113 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）.Conclusion：Patients with peg-shaped upper lateral incisors show Class Ⅲ skeletal pattern with maxillary retrognathia and mandibular prognathism.
