目的评价单颌拔牙后即刻种植及修复的临床效果和特点,探讨适合国人解剖条件的单颌拔牙即刻种植即刻修复技术.方法 2008年6月至2012年3月接受单颌拔牙后即刻种植即刻修复的患者46例(男性28例,女性18例),年龄:37～ 75岁(平均55.4岁)；共植人种植体254枚,种植体植入当天完成种植体支持的无牙颌即刻固定修复,共计56件螺丝固位的种植即刻固定义齿.即刻修复后观察种植体的存留率、种植体边缘骨吸收情况、修复体功能状况、义齿清洁度、并发症,并进行了患者满意度调查.追踪时间9～54个月,平均36.7个月.结果 254枚种植体中的13枚种植体脱落,种植体存留率为94.9％(241/254).即刻修复义齿的存留率94.6％(53/56),边缘骨吸收程度平均(0.7 ±0.3)mm.患者满意率100％.结论单颌拔牙后即刻种植即刻修复技术近期临床效果良好,患者满意度高,远期效果需要进一步观察研究.

Objective To evaluate the outcomes of immediate post-extraction implant and immediate function according to All-on-4 immediate concept in edentulous patients.Methods The study included 46 patients with hopeless teeth.A total of 254 implants were immediately inserted after extraction and 56 fixed complete-arch all-acrylic prostheses finished and functioned on the day of extraction from June 2008 to March 2012 in Peking University School of Stomatology.At time of abutments connection,a panoramic radiograph was taken,and radiographic assessment of the marginal bone level was performed in every 6 months.Marginal bone level,integrity of the restoration,survival of the implants and degree of satisfaction of the patients were evaluated.Results A total of 254 implants were immediate loading.Thirteen implants were lost 6-8 weeks after immediate loading and the survival rate of 94.9 ％ (241/254).The marginal bone absorption was (0.7 ± 0.3) mm on average.All patients were satisfied with the clinical results.Conclusions Immediate post-extraction implant and immediate function technique can be a predictable technique.Further study is needed to determine the long-term results of the technology.
