Multiple treatment options are available to patients who have impacted canines in addition to congenitally absent premolars. Management options for impacted maxillary canines can include (1) continued observation, (2) extraction of the primary canine to aid spontaneous eruption, (3) uncovering and bonding of the impacted tooth and its eruption using orthodontic traction, (4) autotransplantation, and (5) extraction followed by prosthetic replacement. The options for the treatment of missing premolars can include the following: (1) maintaining the primary molars, (2) spontaneous space closure after early extraction of the primary molar, (3) autotransplantation, (4) prosthetic replacement, and (5) orthodontic space closure. In this case report, treatment of a patient with an impacted maxillary canine and agenesis of three second premolars will be presented.
除先天性前磨牙缺失外,对于患有阻生犬齿的患者有多种治疗选择。上颌阻生犬齿的治疗方案可包括:(1)持续观察;(2)拔除乳犬齿以助其自行萌出;(3)暴露并粘结阻生齿,利用正畸牵引助其萌出;(4)自体牙移植;(5)拔除后进行修复替代。治疗缺失前磨牙的方案可包括:(1)保留乳磨牙;(2)早期拔除乳磨牙后自行关闭间隙;(3)自体牙移植;(4)修复替代;(5)正畸关闭间隙。在本病例报告中,将介绍一名上颌阻生犬齿且三颗第二前磨牙先天性缺失患者的治疗情况。
