I've seen research indicating that prior endodontic treatment can raise the risk of peri-implantitis, due to anaerobic bacteria, biofilms, etc., from the root canal. What can an implant surgeon do to minimize these risks? Are there studies (or do you have statistics from your practice) re: the rate of implant failure/peri-implantitis in sites of prior endodontic treatment? (Particularly interested in stats for molars, due to higher complications in root canals w/multiple roots.) Thank you
