目的:探讨球帽基台和locator基台在种植体覆盖义齿( IODs)修复中临床效果的比较。方法选择单颌牙根嵴严重萎缩全口无牙颌患者27例,共计54枚种植体,其中球基台附着体26枚,locator基台附着体28枚。上部修复完成后6个月复诊并每年随访,从种植体、牙周黏膜、附着体等方面进行复查,统计其总的并发症发生率并对患者的满意度进行评价。结果两种基台支持式覆盖义齿患者的满意度明显高于普通全口义齿(P<0.05)。2年后两种附着体种植覆盖义齿边缘骨吸收率(BML)没有差别(P>0.05)。 locator基台支持的覆盖义齿并发症的发生率仅为14.28%,球帽种植覆盖义齿总的并发症发生率为38.46%。结论 locator基台和球帽基台支持式全口义齿均优于常规全口义齿,locator基台产生的并发症更少。%Objective To compare the clinical effects of locator attachment and ball-cap attachment on implant-supported overden-tures. Methods 27 cases of mandibular edentulous were collected for 54 implants, which included 26 ball attachments and 28 locator attachments. All of the patients were followed up for further evaluation after 6 months’ functional loading and continued yearly. Both the incidence rate of prosthetic complications ( including overdentures, implant failures, attachment fractures) and the score of patient sat-isfaction were recorded for statistical analysis during our reexamination. Results The satisfaction of patients with an overdenture sup-ported by attachments was significantly improved(P<0. 05), compared to the complete denture. There was no significant difference in the bone loss between patients with different attachments (P>0. 05), but the complication rate in the group treated with locator attach-ment was 14. 28%, while in the ball attachment group it reached 38. 46%. Conclusion Overdenture supported by locator attachment or ball attachment is more satisfying than the previous complete denture. Furthermore, with regard to the rate of prosthodontic compli-cations, the clinical results of locator attachment was superior to the ball attachment.
