牙列缺损伴错畸形的正畸与种植联合治疗的临床观察

目的探讨正畸与种植义齿联合治疗牙列缺损伴不同程度错畸形的临床效果。方法对17例牙列缺损伴错畸形患者进行正畸治疗，在排齐牙齿和纠正咬合关系的同时开辟种植义齿修复间隙后，行种植义齿修复缺失牙，并根据临床检查和X线检查评价治疗效果。结果17例患者经联合治疗后，均获得良好的咬合功能和美观效果。在缺牙区共植入76枚种植体，随访时间12～48个月，除2枚种植体因种植体周围炎被拔除外，其余74枚种植体均稳定无松动，种植体平均承载32个月，累计成功率为97.4％。结论对于牙列缺损伴错畸形的患者，采用正畸与种植义齿联合治疗，可获得理想的临床治疗效果。

A clinical observation of therapeutic alliance of orthodontics and implant prosthodontics for dentition defect with malocclusion

Objective To explore the clinical effect of the multidisciplinary treatment combined orthodontics with implant prosthodontics for cases of dentition defect with malocclusion.Methods Seventeen cases of dentition defect with malocclusion were observed.All the cases accepted the orthodontic treatment in order to establish normal occlusion and achieve adequate space for implants.After that, the missing teeth were replaced by implant-supported denture.The clinical effect was evaluated by clinical examination and radiographic examination.Results Satisfactory esthetic and functional results were achieved for all the cases.The follow-up time ranged from 12 months to 48 months.76 implants were inserted totally.Two of them were extracted due to peri-implantitis.However, the other 74 implants were stable with an average loading time of 32 months.The cumulative survival rate was 97.4%.Conclusion The multidisciplinary approach combined orthodontics with implant prosthodontics was an effective treatment option for cases of dentiton defect with malocclusion.
