The marginal periodontium of 29 impacted upper canines and several aspects of their treatment have been studied. The situation has been analysed after treatment according to 3 methods of surgery and orthodontics: a) excision and active eruption, b) excision and passive eruption and c) replaced flap and active eruption. Many aspects regarding the choice and course of treatment depend primarily on individual data of the patient and on the location of impaction. With surgical exposure by excision some mucogingival problems seem to appear, especially for vestibular impactions. In those cases the surgical techniques using replaced or deplaced flaps seem to be more indicated to preserve the periodontal tissues.
对29颗上颌阻生尖牙的边缘牙周组织及其治疗的几个方面进行了研究。根据三种手术和正畸治疗方法，对治疗后的情况进行了分析：a）切除并进行主动萌出，b）切除并进行被动萌出，c）翻瓣并进行主动萌出。治疗方法的选择和过程的许多方面主要取决于患者的个体数据和阻生位置。通过切除进行手术暴露时，似乎会出现一些膜龈问题，尤其是前庭阻生的情况。在这些情况下，使用翻瓣或移位瓣的手术技术似乎更有利于保留牙周组织。
