摘　　要：上颌尖牙是牙列中除第三磨牙外最易发生阻生的牙齿,对美观及咀嚼功能有重要作用。临床上对于垂直位或半垂直位阻生尖牙大多易于通过正畸牵引入牙弓,而水平阻生的尖牙矫治难度较大。该文报告1例通过外科开窗联合自制弹性牵引装置成功矫治成人上颌腭侧阻生尖牙,评价其治疗方法的可行性及疗效。Maxillary canine is the second most commonly impacted tooth after the third molar,which is important both esthetically and functionally, Most maxillary canines vertically or near vertically positioned are easy to be tracted into the dental arch,while horizontally positioned canines are more difficult and time-consuming to treat. We report a case of adult patient with palatally impacted maxillary ca- nine, who was successfully treated by surgical exposure combined with orthodontic traction with self-designed elastic device. Evaluation of the feasibility and efficacy of the treating method was given.
