A 7-year follow-up of implants placed immediately after tooth extraction into fresh extraction sites is reported. Small autogenous bone chips (from bone adjacent to implant sites) were grafted into the defect between the implant and the socket walls when needed. Closure of the wound was obtained by coronal repositioning of the flap, and no membranes were used. Care was taken to minimize hematoma formation under the flap during healing by part-time use of removable prosthesis with thick soft linings after implant surgery. At second stage surgery, mucoperiosteal flaps were apically repositioned for maximum attached gingival width and to reconstruct the vestibule. Minor complications such as exposure occurred in 16% of cases. Implant mean 5-year cumulative survival rate was 95%. There was no implant loss after loading. The results indicated that implants placed into fresh extraction sites grafted with autogenous bone chips will heal predictably.
本文报告了对拔牙后立即植入新鲜拔牙窝的种植体进行的7年随访情况。必要时，将小的自体骨屑（取自种植体部位附近的骨）移植到种植体与牙槽窝壁之间的缺损处。通过瓣的冠向复位实现伤口闭合，未使用膜。种植手术后，通过兼职使用带有厚软衬里的可摘义齿，尽量减少愈合过程中瓣下血肿的形成。在二期手术中，将粘骨膜瓣向根尖方向复位，以获得最大的附着龈宽度并重建前庭。16%的病例出现了如暴露等轻微并发症。种植体的平均5年累积生存率为95%。加载后无种植体丢失。结果表明，植入新鲜拔牙窝并移植自体骨屑的种植体将可预测地愈合。
