摘要
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 tile 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.
