Comparison of the effects of air-powder abrasion, chemical decontamination, or their combination in open-flap surface decontamination of implants failed for peri-implantitis: an ex vivo study
Objectives To compare, using an ex vivo model, the biofilm removal of three surface decontamination methods following
surgical exposure of implants failed for severe peri-implantitis.
Materials and methods The study design was a single-blind, randomized, controlled, ex vivo investigation with intra-subject
control. Study participants were 20 consecutive patients with at least 4 hopeless implants, in function for >12 months and with
progressive bone loss exceeding 50%, which had to be explanted. Implants of each patient were randomly assigned to the
