目的：分析上颌尖牙阻生的患病率、分布、临床特点及其与牙体畸形的关系。材料与方法：对1674例正畸患者完整的治疗前记录进行检查。受试者上颌埋伏尖牙分为两个研究组：腭移位尖牙（PDC）组（114例）和颊移位尖牙（BDC）组（37例）。将这些患者与从初始样本中随机选择的151名无上颌尖牙嵌塞的患者对照组进行比较。犬齿嵌塞和牙齿和临床特征和异常之间的关联的意义进行了检查与卡方test.Results：PDC患者提出了正常的覆盖和面部轮廓和较低程度的牙弓拥挤相比，对照组患者。PDC患者的其他牙齿阻生、牙发育不全、移位和桩形上颌侧切牙的患病率较高（比值比分别为3.3、2.6、8.3和5.8）。与对照组相比，BDC组患者在临床和牙齿特征或牙齿异常方面没有显着差异。（角度正交。2013;83：22-28.）
Objective: To analyze the prevalence, distribution, clinical features, and relationship with dental anomalies of maxillary canine impaction.Materials and Methods: The complete pretreatment records of 1674 orthodontic patients were examined. Subjects with maxillary impacted canines were divided into two study groups: a palatally displaced canine (PDC) group (114 patients) and a buccally displaced canine (BDC) group (37 patients). These were compared to a control group of 151 patients who were randomly selected from the initial sample without maxillary canine impaction. The significance of associations between canine impaction and dental and clinical features and anomalies was examined with the chi-square test.Results: PDC patients presented with normal overjet and facial profile and a lower degree of dental arch crowding in comparison to the control patients. PDC patients showed a higher prevalence of impaction of other teeth, dental aplasia, transposition, and peg-shaped maxillary lateral incisors (odds ratios 3.3, 2.6, 8.3, and 5.8, respectively).Conclusion: PDC was frequently the only orthodontic problem of patients. BDC group patients did not present with notable differences in clinical and dental features or dental anomalies compared to control subjects. (Angle Orthod. 2013;83:22-28.)
