The influence of platform switching in dental implants. A literature review.

Introduction: The platform switching concept involves the reduction of the restoration abutment diameter with respect to the diameter of the dental implant. In 1991, dental implants of 5 and 6 mm diameter platforms were introduced. However, matching-diameter prosthetic abutments were not available. These implants were restored with “standard”-diameter prosthetic components (4,1 mm). Long-term follow up around these wide-platforms showed higher levels of bone preservation. In time, it has been called platform switching. The first case report applying this concept was indexed in MedLine in 2005. Materials and Methods: The aim of this article is to carry out a literature review of articles whi…
