平台转换技术的特点和研究现状

摘要/Abstract

摘要： 过去几年中，用于维持种植体周围骨水平的平台转换种植体较受欢迎。平台转换技术指的是使用较小直径的修复体基台，将其放置在较大直径的种植体上，使种植体基台界面的外侧缘转移到种植体靠近中轴处，向内水平重新定位而远离了种植体颈部的外侧缘。大量文献支持平台转换技术有利于种植体周围软硬组织的稳定，该文就平台转换技术对软硬组织的影响和原因分析等方面作一综述。

Abstract: Platform switching for maintaining peri-implant bone levels has gained popularity among implant manufacturers over the last few years. The platform switching technique refers to the use of a smaller diameter prosthetic abutment, which is placed on a larger diameter implant so that the outer edge of the implant-abutment junction is horizontally repositioned inwardly and away from the outer edge of the implant platform. A large number of literatures support that the platform switching technique is conducive to the stability of hard and soft tissues around implants. In this paper, the influence of platform switching technique on soft and hard tissue and its causes, mechanical complications are reviewed.

Key words: platform switching, marginal bone loss, biological width, implant-abutment junction
