The goal of this investigation was to evaluate the bone-to-implant contact (BIC) of dental implants placed into fresh extraction sockets without pre-existing periapical pathology. When the extraction sites exhibited a gap distance of > 2 mm, autogenous bone harvested from surrounding surgical sites was grafted to fill that gap with no barrier membranes. All implants were clinically stable and successful at 6 months postoperative. The histologic examination demonstrated an average of 66.2% BIC for all five immediately placed dental implants. The results of this study provided sufficient histologic and histomorphometric knowledge to support immediate dental implant placement in carefully selected clinical scenarios.
本研究的目的是评估植入无根尖周病变的新鲜拔牙窝内的牙种植体的骨结合（BIC）情况。当拔牙部位的间隙距离>2mm时，从周围手术部位采集自体骨进行移植以填充该间隙，不使用屏障膜。所有种植体在术后6个月时临床稳定且成功。组织学检查显示，所有五颗即刻植入的牙种植体的平均骨结合率为66.2%。本研究结果提供了足够的组织学和组织形态计量学知识，以支持在精心挑选的临床病例中即刻植入牙种植体。
