Evaluating Non-Surgical Peri-Implantitis Treatment With or Without Removing the Prosthetic Crown A Randomized Clinical Trial

What this Trial Is About

Researchers are evaluating how removing the prosthetic crown affects non-surgical mechanical treatment for implants with peri-implantitis. The goal is to compare clinical and radiographic changes at baseline and after 3, 6, and 12 months. The main measure is the average probing depth around the implant, with additional focus on gum recession, bone levels, bleeding scores, and patient factors. The study has two groups one where the prosthetic crown is temporarily removed before treatment to allow better access for cleaning, and another where the crown remains in place during therapy. Both groups receive mechanical debridement under local anesthesia using sonic and ultrasonic devices with thin tips and Gracey curettes, following clinical guidelines. After cleaning, crowns are replaced in the removal group, and all patients get oral hygiene instructions. Participants will be assessed through clinical exams and radiographic imaging at specified intervals up to one year. Researchers will measure gum and bone changes, bleeding, and implant pocket depth to evaluate treatment effects. Safety and adherence will be monitored throughout, with a total study duration of 12 months from enrollment to final evaluation.
