The objective of this retrospective study was to evaluate the overall success of immediately loaded implants in the mandible. This report focuses on immediately loaded anterior and posterior mandibular implants.
A total of 979 patients received 2,904 mandibular dental implants placed from January 2007 to December 2008. One hundred sixty-one of the implants were placed anterior to the mental foramen, and 95 were placed posterior to the mental foramen. All immediately loaded implants were torque tested to 35 N-cm. All were provisionally restored the day of insertion.
A total of 256 immediately loaded mandibular dental implants were placed in a 2-year period. Of the 256 immediately loaded implants, 252 integrated and were restored and 4 failed. Of the 4 failed implants, 3 were in the anterior mandible and the fourth was in the posterior mandible. All 4 were replaced, integrated, and have been restored. The survival rate for immediately loaded implants in the anterior mandible was 99.4%, and the survival rate in the posterior mandible was 97%.
Immediately loaded implants have predictable clinical success in the anterior and posterior mandible.
本回顾性研究的目的是评估下颌骨即刻负重种植体的总体成功率。本报告重点关注下颌骨前部和后部的即刻负重种植体。
2007年1月至2008年12月期间，共有979例患者接受了2904颗下颌牙种植体植入。其中161颗种植体植入颏孔前方，95颗植入颏孔后方。所有即刻负重种植体均进行了35 N-cm的扭矩测试。所有种植体在植入当天进行临时修复。
在2年时间里共植入256颗下颌即刻负重牙种植体。在这256颗即刻负重种植体中，252颗成功整合并完成修复，4颗失败。在4颗失败的种植体中，3颗位于下颌前部，第4颗位于下颌后部。所有4颗均被替换、整合并完成修复。下颌前部即刻负重种植体的生存率为99.4%，下颌后部为97%。
即刻负重种植体在下颌骨前部和后部均具有可预测的临床成功率。
