The overall success of dental implants depends on the crestal bone support around the implants. During the initial years of dental implant placement, the bone loss around the implants determines the success rate of treatment. Platform switching (PLS) concept preserves the crestal bone loss, and this approach should be applied clinically for the overall success of dental implants.
The purpose of this study is to discuss the literature dealing with the concept of PLS concept and preservation of marginal bone, the mechanism by which it contributes to maintenance of marginal bone, its clinical applications, advantages, and disadvantages, to assess its survival rates.
PubMed and Google Scholar search was done to find out the studies involving PLS concept from 2005 to 2017. Data were analyzed using SPSS statistical software.
Literature search revealed studies involving concepts of PLS, comparison of platform-switched and nonplatform-switched implants, case reports on PLS, and studies with histological and finite element analyses regarding PLS.
PLS helps preserve crestal bone around the implants, and this concept should be followed when clinical situations in implant placement permit.
牙种植体的总体成功取决于种植体周围的嵴骨支持。在牙种植体植入的最初几年，种植体周围的骨吸收决定了治疗的成功率。平台转换（PLS）概念可减少嵴骨吸收，临床上应采用这种方法以确保牙种植体的总体成功。
本研究旨在探讨有关PLS概念和边缘骨保存的文献，其促进边缘骨维持的机制、临床应用、优缺点，并评估其生存率。
通过PubMed和谷歌学术搜索2005年至2017年涉及PLS概念的研究。使用SPSS统计软件分析数据。
文献检索发现了涉及PLS概念的研究、平台转换种植体与非平台转换种植体的比较、PLS的病例报告以及有关PLS的组织学和有限元分析研究。
PLS有助于保留种植体周围的嵴骨，在种植体植入的临床情况允许时应遵循这一概念。
