This prospective clinical study evaluated the 5-year survival and success rates of 66 titanium implants placed in bone that had been previously augmented with autografts and nonresorbable barrier membranes. During the observation period, three patients with five implants dropped out of the study. None of the remaining 61 implants were lost during the follow-up period (implant survival rate of 100%). One implant exhibited a periimplant infection, whereas 60 implants were considered clinically successful at the 5-year examination, resulting in a 5-year success rate of 98.3%. It can be concluded that the clinical results of implants in regenerated bone are comparable to those of implants in nonregenerated bone.
这项前瞻性临床研究评估了66颗钛种植体在先前已用自体骨移植和不可吸收屏障膜进行骨增量的骨中的5年生存率和成功率。在观察期内，三名患者的五颗种植体退出了研究。在随访期间，其余61颗种植体无一丢失（种植体生存率为100%）。一颗种植体出现种植体周围感染，而在5年检查时，60颗种植体被认为临床成功，5年成功率为98.3%。可以得出结论，再生骨中种植体的临床结果与非再生骨中种植体的临床结果相当。
