Background: The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform switching is an approach which can be clinically applied to preserve the crestal bone. Purpose: The purpose of this review is to discuss the literature dealing with the platform switching concept to preserve the crestal bone, the mechanism by which it contributes to maintenance of marginal bone, its clinical applications, advantages and disadvantages, in order to assess its survival rates. Materials and Methods: PubMed and Google Scholar were used to find studies involving platform switching concept from 2005 up to October 2009. Results: Literature search revealed studies involving concepts of platform switching, comparison of platform-switched and non-platform-switched implants, case reports on platform switching and studies with histological and finite element analyses regarding platform switching. Conclusion: Platform switching helps preserve crestal bone around the implants and this concept should be followed when clinical situations in implant placement permit.
