上/下全牙列缺失的即刻修复和即刻负重的近期疗效观察

目的:本文旨在报告作者对上下颌全牙列缺失采用Diem系统行即刻修复和即刻负重6-9月后的临床经验和临床结果。材料和方法:本组病例共7例,其中女性一例,男6例,平均年龄55.97±7.25SD岁,共植入51颗肩台转换种植体;2例13颗植入上颌,7例共38颗植入下颌,其中2例为全口牙缺失。在植入种植体的当天安装Diem标准IOL基台,完成修复体均采用螺丝固位。永久修复在6-8周完成,观察时间6-9月。结果:一颗植体在三月时松动拔除(1.9%)。其余肩台转换种植体骨吸收均小于0.6mm.结论:本组病例在随访期间CSR为98.1%,采用Diem的IOL基台的上下颌全牙列缺失的即刻修复和即刻负重是可靠和有效的。

Objective:The aim of this study was to report on our experience and outcomes with Certain Prevail Implants and immediate loading via the Diem System after a 9-month follow-up period.Materials and Methods:Over a 9-month period,51(13 maxilla,38 mandible)expanded-platform implants were placed in 7 patients(1 females,6 males;55.97 ±7.25 SD years).All prostheses were screw mounted on IOL DIEM standard abutments at the day of implant placement.The follow-up time varied between 6 up to 9 months.Results:One implant(1.9%)failed during final prothetic placement(3 months).The crestal bone resorption was 0.6 mm at 9 months in platform switching implants.Conclusions:The cumulative implant survival rate during the follow-up period was 98.1% Immediate loading on IOL Diem abutments is a reliable and effective technique for edentulous patients in the maxilla and mandible.
