Platform switching for marginal bone preservation around dental implants: A systematic review

Abstract

For maintaining peri-implant bone levels, Platform switching has gained popularity among implant manufacturers in the past few years. Greater magnitude and occurrence of bone loss during first year of prosthetic loading. However, the assumption that the inward shifting of the implant-abutment junction may preserve crestal bone was primarily based on serendipitous finding rather than scientific evidence. This paper reviews the literature regarding platform switching, the crestal bone preservation and its endurance.
