本研究对Branemark（TM）口腔种植体进行回顾性研究，从1988年到1993年，连续75例患者使用84种种植体进行单牙置换术。两个种植体丢失且未更换：第一个在基台连接之前，后者在功能的第一年。5年间累计故障率达2.4%。71%的种植体位于双颌的门牙/犬齿区域。26%的植入物是在特殊的术前或手术条件下植入的。根据x线片评分，第一年的平均年骨质流失为0.8 mm，随后几年为0.1 mm。使用不同的种植体设计，锥形种植体观察到更明显的骨质流失。目前的数据表明，单个Branemark（TM）种植体的累积失败率和x线骨丢失与用于治疗全牙和部分全牙的种植体相似。(C) Munksgaard, 1996。
In this retrospective study of Branemark(TM) system oral implants, 75 consecutive patients were treated with 84 implants for single-tooth replacement from 1988 to 1993. Two implants were lost and not replaced: the first one before the abutment connection, the latter during the first year in function. The cumulative failure rate reached 2.4% during the 5-year period. Seventy-one percent of the implants were located in the incisor/canine region of both jaws. Twenty-six per cent of the implants were inserted in special presurgical or surgical conditions. The mean annual bone loss as scored on radiograph, was 0.8 mm during the first year and 0.1 mm the following years. Different implant designs were used, a more pronounced bone loss was observed for the conical implant. The present data shows that the cumulative failure rate for single Branemark(TM) implants and the radiographic bone loss is similar to that found around implants used for the treatment of complete and partial edentulism.
