Clinic experience of mini-SG attachment applied in dentition defect of Kennedy class Ⅰ with severe abrasion of residual teeth

目的:观察Mini-SG附着体义齿修复双端游离缺失伴余留牙重度磨损的临床效果。方法:对12例双端游离缺失伴余留牙重度磨损患者,应用Mini-SG附着体义齿进行修复。结果:经过6个月-5年的临床随访,Mini-SG附着体义齿稳定性能好,患者满意,基牙牙周组织健康。结论:Mini-SG附着体义齿是修复双端游离缺失伴余留牙重度磨损的较好方法,有利于基牙的牙周组织健康。

Objective：Observe the clinic effect of Mini-SG attachment applied in dentition defect of Kennedy class Ⅰ with severe abrasion of residual teeth.Method：Mini-SG attachment was applied in 12 cases with dentition defect of Kennedy class Ⅰ with severe abrasion of residual teeth.The stability of prosthesis,satisfaction rate and periodontal condition of abutment were studied in 6 months to 5 years.Result：The Mini-SG attachment was stable to exert chewing function while healthy periodontal tissues were kept in the abutments.Patients were satisfied with the prosthesis.Conclusion：It is indicated that Mini-SG attachment is a good method to rehabilitate the dentition defect of Kennedy class Ⅰ with severe abrasion of residual teeth.It solved the problem of abutments tooth injury in contrast to conventional ways.
