Platform Switching in Dental Implants

Researchers have attempted to explain the mechanism of action of platform switching; however it is necessary to conduct further studies including histological studies using animals to clarify the mechanism fully. With respect to radiographic evaluations of crestal bone levels in humans properly designed long- term observation is required before establishing the long-term predictability of platform switching in preserving horizontal and vertical marginal bone levels or modifying the minimum distances between platform-switched implants and adjacent teeth or implants particularly through prospective randomized multicenter trials with large number of participants.
