这项研究包括 4,641 颗 Brånemark 牙种植体，从第一阶段手术到修复体完成进行了回顾性随访。在 3 年期间（1986 年至 1988 年），种植体被植入 943 个颌骨中，代表 889 名完全无牙颌和部分无牙颌患者。下颌和性别分布显示下颌骨（564/943）和女性（534/943）占主导地位。种植体植入时患者的平均年龄为 57.5 岁（范围 13 至 88 岁）。只有 69 个（1.5%）固定器未能整合，大多数损失发生在完全无牙颌上颌骨（46/69），其中颌骨表现出软质和严重吸收。在最短的固定装置（7 毫米）中也可以看到大部分故障。大多数移动种植体是在基台连接（第 2 阶段）操作时记录的 (48/69)。
This study comprised 4,641 Brånemark dental implants, which were retrospectively followed from stage 1 surgery to completion of the prosthetic restorations. The implants were placed during a 3-year period (1986 to 1988) in 943 jaws, representing 889 patients with complete and partial edentulism. The jaw and sex distribution revealed a predominance of mandibles (564/943) and females (534/943). The mean age of the patients was 57.5 years (range 13 to 88 years) at implant placement. Only 69 (1.5%) fixtures failed to integrate, and most losses were seen in completely edentulous maxillae (46/69), in which the jaw bone exhibited soft quality and severe resorption. A preponderance of failures could also be seen among the shortest fixtures (7 mm). A majority of the mobile implants were recorded at the abutment connection (stage 2) operation (48/69).
