Abstract

Canines are among the most commonly impacted teeth. When a canine is positioned labially, the untoward soft-tissue responses following surgical exposure may cause unfavorable esthetic outcomes. Therefore, decision making as to the choice of a proper surgical technique to uncover labially impacted teeth is critical. This case presentation describes two different surgical approaches for two maxillary impacted canines in a 12-year-old girl. A sequential approach included a first stage of surgical exposure using apically positioned flaps and orthodontic extrusion of both impacted teeth. A successive laterally positioned flap was used for the left maxillary canine to achieve a harmonious soft-tissue contour. In this case, close monitoring and cooperation during the various treatment phases led to proper canine positioning and a successful esthetic result, with good periodontal health and functional occlusion.

摘要

尖牙是最常受到阻生的牙齿之一。当尖牙位于唇侧时,手术暴露后不良的软组织反应可能会导致不理想的美学效果。因此,决定采用何种合适的手术技术来暴露唇侧阻生牙至关重要。本病例报告描述了一名12岁女孩两颗上颌阻生尖牙的两种不同手术方法。一种序贯方法包括第一阶段使用根尖定位瓣进行手术暴露以及对两颗阻生牙进行正畸牵引。对于左上尖牙,随后使用侧向定位瓣以实现和谐的软组织轮廓。在本病例中,在各个治疗阶段进行密切监测与合作,使尖牙得以正确定位,并获得了成功的美学效果,同时牙周健康状况良好且咬合功能正常。
