摘　　要：目的探讨种植套筒冠义齿修复无牙颌的临床效果。方法 15例无牙颌患者,采用种植套筒冠义齿修复。共完成26件修复体,其中上颌义齿11件,下颌义齿15件。共植入种植体104颗,修复基台研磨后直接作为套筒冠内冠,套筒冠外冠采用失蜡铸造技术加工。修复后平均回访32个月,对所有种植体及上部结构进行临床及影像学检查,并对原总义齿和种植套筒冠义齿满意度进行比较。结果完成种植体支持修复的26件覆盖义齿,所有上部修复体的外冠与种植体基台间固位较好、义齿稳定,患者对覆盖义齿的舒适度和咀嚼功能满意,在舒适度和咀嚼功能方面,患者的种植套筒冠义齿满意度要高于常规总义齿,差异有统计学意义(P<0.05),而发音方面二者差异无统计学意义(P>0.05)。覆盖义齿在观察时间内未发生松动、折断及损坏,种植体无松动或脱落。随访期内,种植体周围牙槽骨平均垂直骨吸收量约1 mm。结论本研究结果表明,种植套筒冠义齿修复无牙颌是一种可靠的方法,但仍需要进一步长期观察。Objective To study the effect of the edentulous arch with implant supported telescopic overdenture.Methods Fifteen patients with edentulous jaws underwent telescopic overdenture restoration.A total of26prostheseswere fabricated(11in the upper jaws,15in the lower jaws)with104placed implants.The secondary crown was fabri?cated by wax?lost cast method.Clinical examination and radiographs were conducted.Changes in the marginal bone lev?el around the implants were evaluated by radiograph.The satisfaction level of complete denture and implant?supportedoverdenture were compared.The mean follow?up time was32months(range6?60months).Results Twenty?six pros?theses showed better stability,maintenance and occlusion.There were statistical differences between complete dentureand implant?supported overdenture in comfort level and chewing function.1mm bone lost was found in two patients af?ter4years.No implant was lost during the loading time.Conclusion The preliminary clinical results of this researchshowed that implant supported telescopic overdentures were reliable for edentulous patients.
