目的：探讨上颌锥形侧切牙患者颌面形态发育特征。方法选取98例12～25岁的上颌锥形侧切牙患者作为研究对象，拍摄头颅侧位片，对其进行X线头影测量分析。结果98例患者中，1颗锥形侧切56例占57．1％，2颗锥形侧切牙42例占42．9％。98例患者的矢状面型：安氏Ⅰ类面型40例占40．8％，Ⅱ类面型8例占8．2％，Ⅲ类面型50例占51．0％；垂直面型：高角型46例占46．9％，均角型20例占20．4％，低角型32例占32．7％。结论上颌锥形侧切牙患者矢状向主要表现为Ⅰ类和Ⅲ类面型；垂直向主要表现为均角型和低角型面型，颌面形态特征表现为上颌骨发育不足，下颌骨发育过度，面中部软组织凹陷。

Objective To analyze the characteristics of maxillofacial morphology in patients with peg-shaped upper lateral incisors .Methods Ninety-eight patients with peg-shaped upper lateral incisors aged 12-25 years old were enrolled in the study .The lateral cephalograms were taken for a data analysis .Results Among these 98 cases,56 had one peg-shaped upper lateral incisor (57.1%),42 had two(42.9%).The sagittal skeletal patterns were skeletal ClassⅠ(n=40, 40.8%),skeletal ClassⅡ(n=8,8.2%) and skeletal Class Ⅲ(n=50,51.0%).The vertical skeletal patterns were high vertical type (n=46,46.9%),average vertical type (n=20,20.4%) and low vertical type (n=32, 32 .7%) .Conclusion Patients with peg-shaped upper lateral incisors mainly show Class ⅠandⅢskeletal pattern , vertical skeletal pattern of average and low vertical type with maxillary hypoplasia ,mandibular hyperplasia and midfacial deformity.
