摘要/Abstract

摘要： 在传统种植修复方案中,为完成最终修复需多次拆装修复组件,这可能导致黏膜屏障受损、纤维结缔组织向根方移位,并引发种植体周围边缘骨吸收。为解决这一问题,Degidi于2011年提出“一次性置入永久基台”(one-abutment one-time, OA-OT)概念,即在种植体植入或二期手术时直接安装最终基台,避免愈合基台、转移杆及修复基台的反复拆装,从而最大限度减少基台更换及取模过程对种植体周围组织的创伤。研究表明,在种植手术中放置永久基台有助于保留更多的种植体周围骨组织。然而,对于此方法是否显著改善种植体周围软硬组织的长期稳定性,仍存争议。本文综述了在种植手术中一次性置入永久基台对种植体周围软硬组织的影响及应用前景。

Abstract: Conventional implant restoration often involves repeated assembly and removal of components, which can damage the mucosal barrier, displace fibrous tissue, and cause marginal bone loss. To address this, the one-abutment one-time (OA-OT) concept, introduced by Degidi in 2011, advocates placing the final abutment at the time of implant placement or during the second-stage surgery. This approach avoids multiple adjustments of healing abutments, transfer bars, and restorative abutments, reducing trauma to peri-implant tissues. While studies suggest that OA-OT placement preserves more peri-implant bone, its impact on the long-term stability of soft and hard tissues remains debated. This review explores the effects and application prospect of OA-OT on peri-implant tissue stability.
