Messias A, et al. - Implants restored with platform-switching (PS) or platform-matching (PM) abutments were compared regarding the clinical performance and marginal bone levels. Thirty-three patients missing two or more adjacent teeth in the posterior mandible received 72 implants [CAMLOG SCREW-LINE implants] in the PM group and thirty-five patients received 74 implants in the PS group. Sixty patients attended the final appointment, 31 had received PS components with 65 implants and 29 had received PM components with 63 implants. Outcomes support the benefit of using PS components in terms of peri-implant marginal bone level maintenance among patients requiring implant supported restorations in healed bounded or free end edentulous gaps of the mandible, though it may not be clinically noticeable.
