Treatment of impacted teeth is often a combination between oral surgery and orthodontics. This study evaluates the gingival condition of impacted teeth after surgical-orthodontic treatment, where two different surgical methods were used. In one group (n = 11) the teeth were radically exposed and orthodontically moved to their final position. In the other group (n = 11) the teeth were partially exposed by raising a mucoperiosteal flap. Orthodontic traction was then applied; whereafter the flap was sutured back into place. The results showed that one of the teeth in the partial exposure group and seven in the radical exposure group showed loss of attachment. This study indicates that a combination of mucoperiosteal flap technique and applied orthodontic traction is prefered to minimize the loss of attachment in cases of displaced impacted teeth.
阻生牙的治疗通常是口腔外科手术与正畸治疗相结合。本研究评估了采用两种不同手术方法进行外科正畸治疗后阻生牙的牙龈状况。一组（n = 11）牙齿被完全暴露并通过正畸移动到最终位置。另一组（n = 11）通过掀起黏骨膜瓣使牙齿部分暴露。然后施加正畸牵引；之后将瓣缝合回原位。结果显示，部分暴露组有一颗牙齿，完全暴露组有七颗牙齿出现附着丧失。本研究表明，在处理移位阻生牙时，黏骨膜瓣技术与正畸牵引相结合更有利于减少附着丧失。
