Abstract
In the first year after implant insertion, a physiological peri-implant bone level alteration of 0.5 - 2mm is expected. In the subsequent years, the rate of bone loss slows to about 0 - 0.2mm per year. Platform switching has been used to a large extent, as it allows bone remodeling around the implant favoring the maintenance of the bone crest with the reduction in stress in the cervical region of the implant. Ten completely edentulous patients received 4 mandibular implants in a split mouth technique 2 with regular platform and 2 with platform switching. Bone height and bone density were evaluated. After 1 year, there was no statically significant difference between regular implants and platform switched implants. Within the limitations of this study it was shown that platform switched implants doesn{u2019}t have an effect on crestal bone changes
