Orthodontic extrusion with multidisciplinary treatment can provide predictable outcomes in selected situations, reducing the costs and the adaptation times of gingival tissues after implant integration. Forced orthodontic extrusion is strongly related to interactions of teeth with their supportive periodontal tissues. This article reports a case of orthodontic extrusion of the maxillary incisors for later implant rehabilitation in a patient with periodontal disease. Slow forces were applied for 14 months. After this time, the teeth were extracted, and the implants were placed on the same day. Also in the same session, the provisional crown was fabricated for restoration of the anterior maxillary interdental papillae loss and for gingival contouring. Clinical and radiographic examinations at the 6-year follow-up showed successful tooth replacement and an improved esthetic appearance achieved by this multidisciplinary treatment. The decision to perform orthodontic extrusion for implant placement in adult patients should be multidisciplinary.
正畸牙内收联合多学科治疗可在特定情况下提供可预测的结果,减少种植体整合后牙龈组织的成本和适应时间。正畸牙强制内收与牙齿与其支持性牙周组织的相互作用密切相关。本文报告了一例牙周病患者的上颌切牙正畸牙内收,以进行后期种植修复。缓慢的力量施加了 14 个月。此时,牙齿被拔除,同一天植入物被放置。在同一治疗中,还制作了临时冠,以修复前上颌牙间乳头缺失和牙龈轮廓。6 年随访的临床和影像学检查显示,多学科治疗成功地替代了牙齿,并改善了美观效果。对于成年患者进行正畸牙内收以进行种植体放置的决策应是多学科的。
