Treatment of palatally impacted and transposed canines is challenging for both orthodontists and oral surgeons. To treat a maxillary canine impaction without risking damage to adjacent teeth, it is necessary to use cone-beam computed tomography for proper localization and treatment planning. In this case report, a palatally impacted canine was initially retracted distally with a microimplant inserted in the palatal slope and then was moved buccally into its ideal position. The patient's occlusion and smile esthetics were significantly improved after orthodontic treatment.
对于正畸医生和口腔外科医生而言，治疗腭侧阻生和异位萌出的尖牙都颇具挑战性。为了在不损伤相邻牙齿的情况下治疗上颌尖牙阻生，有必要使用锥形束计算机断层扫描进行精确的定位和治疗规划。在本病例报告中，一颗腭侧阻生的尖牙首先通过植入腭侧斜面的微型种植体向远中牵引，然后颊向移动至理想位置。正畸治疗后，患者的咬合和微笑美观度得到了显著改善。
