"All-on-4"种植即刻修复治疗的临床回顾性分析

目的 分析施行"All-on-4"种植即刻修复病例的种植体存留率及并发症发生情况,探讨"All-on-4"的技术要点及注意事项.方法 根据纳入及排除标准,纳入2007年1月~2015年12月完成的"All-on-4"种植即刻修复治疗的病例共23例108枚种植体,其中上颌牙列缺失5例,下颌牙列缺失14例,全口牙列缺失4例,均在术后当天或1~2d内取模,并于术后7~10d戴入临时固定修复体,采用螺丝固位,术后3~6个月取模并制作最终修复体,共完成27件临时修复体及27件最终修复体.完成最终修复后平均追踪3年(1~9年),对种植体留存率、修复并发症进行总结及分析.结果 108枚种植体及27件最终修复体至最后1次复查为止,种植体存留率100%.23位患者当中,3位患者发生并发症,并发症发生率13.0%.结论 "All-on-4"在牙列缺失病例治疗中疗效确切可靠,并发症的发生率较低,是一种切实可行的方法.

Immediate repair of All-on-4 implants: a clinical retrospective study

Objective To analyze implant survival rate and incidence rate of complications after All-on-4 implanta-tion,and to discuss the technical points and consideration of All-on-4.Methods According to the criteria of inclusion and exclusion, 23 cases treated with All-on-4 immediate restoration were referred, from January 2007 to December 2015, including 5 cases of edentulous maxillary, 14 cases of edentulous mandibular and 4 cases of both maxillary and mandibular were edentulous. All the patients received immediate function with provisional prostheses at the surgery day.Definitive prostheses were delivered to patients after 3-6 months post operation and follow-up visits were performed up to 9 years(average 3 years)after placement of definitive prostheses. Results In this study, the rate of implant re-tention of 108 implants and 27 final restorations was 100% until the last review.Among the 23 patients,3 patients had complications and the incidence of complications was 13.0%.Conclusion All-on-4 is an effective and reliable meth-od in the treatment of dentures denture.The incidence of complications is low.All-on-4 is a practical method.
