摘　　要：近年来,种植体研发设计的进步促进了临床技术的发展,尤其是平台转移技术(platform switching,PLS),其生物学益处及临床效果已被许多研究报道所证实。该技术在2005年被首次提出,目前有大量临床研究证实PLS技术可以减少种植体周围边缘性骨组织的吸收。本文从PLS技术的生物学宽度、种植体基台连接微间隙、应力学分布等不同方面进行回顾讨论。但在关于即刻负重与动物研究中发现的问题,仍需要通过对大量种植体进行长期的、随机对照、前瞻性和多中心试验来研究探明。In recent years,advances in the research and development of implants,especially platform switching(PLS),have promoted the development of clinical techniques.Its biological benefits and clinical effects have been confirmed by many research reports.This technology was first proposed in 2005.At present,a large number of clinical studies have confirmed that PLS technology can reduce the absorption of marginal bone tissue around the implant.This article reviews the biological width of PLS technology,the micro-gap of implant abutment,and the distribution of stress.However,the problems found in the study of immediate weight-bearing and animal studies still need to be studied through long-term,randomized,controlled,prospective and multicenter trials on a large number of implants.
