[The marginal periodontium of impacted upper canines. Evaluation following various methods of surgical approach and orthodontic procedures].

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.
