摘要/Abstract

摘要： 目的:收集完成修复后发生基台折断的平台转换种植病例,分析基台折断相关因素及处理方式,为临床提供参考。方法:病例来源为2007~2014年北大口腔医院门诊部完成种植修复的临床病例,纳入标准为:采用Ankylos平台转换种植体;病例以及影像学资料齐全;影像学及临床检查确诊基台折断。结果:基台折断率为0.82%,共有16例,17颗种植体发生18次基台折断,1615颗位于第一磨牙区。患者平均年龄(47.69±9.56)岁,修复体平均负荷时间为(3.89±1.68)年。17颗基台折断种植体均未发现种植体颈部骨质吸收。结论:咬合力较大的第一磨牙区和尖牙区平台转换基台折断好发部位。平台转换种植体在稳定边缘骨方面效果显著,但当第一磨牙区的近远中缺隙过大时,植入平台转换种植体应慎重考虑。

Abstract: Objective: To collect the cases of platform-switching implants with abutment fracture and analyze the reasons for clinical treatment. Methods: We collect platform-switching implants with abutment fracture from 2007 to 2014 in the Outpatient Department of Peking University School of Stomatology. Inclusion criteria: using Ankylos implants; patients with complete data; imaging and clinical examination confirmed abutment fracture. Results: Abutment fracture occurred in 16 patients, 17 implants and 18 abutments, including 9 males and 7 females. The average age was 47.69±9.56 years old. The average functional loading time was 3.89±1.68 years. No bone resorption was observed. Conclusion: Abutment fracture was likely to occur in the first molar and canine regions where the mastication force is great. Platform-switching implants showed the stability of the marginal bone. It should be taken serious consideration to choose platform-switching implant when the space of the tooth is large in the first molar region.
