种植体支持球帽附着体固位下颌覆盖全口义齿的临床应用

Clinical application of implant-supported complete overdenture retained with stud attachment for edentulous mandibles

目的:评价种植体支持球帽附着体固位的下颌覆盖全口义齿临床应用效果。方法:随机选择15例下颌无牙颌患者,每例植入2枚种植体,共植入30枚,随访观察1-12个月,从患者满意度、临床检查及种植体X线片观察修复效果。结果:种植体支持覆盖全口义齿修复下颌无牙颌,义齿固位和咀嚼功能满意率分别为100%和93.3%,义齿稳固,咀嚼功能好。12个月后复查X线片显示种植体周围无明显骨吸收。结论:种植体支持球帽附着体固位覆盖全口义齿修复临床效果良好,可作为下颌无牙颌患者首选修复方案。

Objective： To evaluate clinical effects of implant-supported complete overdentures retained with stud attachment for edentulous mandibles.Methods： Fifteen mandibular edentulous patients were randomly selected,who received implant-supported complete overdentures retained with stud attachment.Thirty implants were used and each patient was placed into 2 implants.After 12 months followed-up period,clinical effects were observed,including patient satisfaction,clinical examination and X-ray examination.Results： After the implant-supported complete overdentures were used in edentulous mandible,the satisfaction of patients in denture retention and masticatory function were 100% and 93.3%,respectively.There was no obvious bone resorption around implants through X-ray photography after 12 months.Conclusion： The implant-supported overdentures with stud attachmentcould be used as the optimal restoration for edentulous patients.
