Twenty-three patients who had completed treatment to resolve the unilateral palatal impaction of a maxillary canine by orthodontic means were examined 2.3 years (mean) after all appliances had been discarded. Scores were noted for the plaque index, gingival index, attached gingiva, pocket depth, and bone support on each of the affected teeth and also on the contralateral canine which had been unaffected and thus acted as a control. In addition, the teeth immediately adjacent to both canines were similarly scored. The results indicated no significant difference in the plaque index and the amount of attached gingiva, while the gingival index, pocket depth, and particularly the bone support all showed statistically valid differences. It is suggested that in these cases a postorthodontic assessment of the state of the supporting tissues be performed and periodontal treatment instituted in those requiring it.
23例通过正畸方法完成上颌尖牙单侧腭侧阻生矫治的患者，在所有矫治器拆除2.3年（平均）后接受检查。记录患牙及对侧未受累作为对照的尖牙的菌斑指数、牙龈指数、附着龈、牙周袋深度和骨支持情况得分。此外，对紧邻两侧尖牙的牙齿也进行同样的评分。结果显示，菌斑指数和附着龈量无显著差异，而牙龈指数、牙周袋深度，尤其是骨支持情况均显示出具有统计学意义的差异。建议对这些病例进行正畸治疗后支持组织状况的评估，并对有需要的患者进行牙周治疗。
