The purpose of the study is to evaluate if using Er:YAG laser could have adjunctive benefits to the conventional standard mechanical debridement to ablate the infected tissue around the dental implant and detoxify the contaminated implant surface for resolving peri-implant infection and enhance bone regeneration of peri-implant defects.~This study involves one center and a double-blinded randomized controlled clinical trial is planned. Twenty-four adult patients in the need of surgical treatment due to peri-implantitis will be included. Six visits are needed for each patient including a 24 week follow-up visit.~Specific Aim 1: To compare the clinical benefit of Er:YAG laser-assisted peri-implant defect debridement and surface detoxification with conventional mechanical debridement for regenerative therapy~Specific Aim 2: To evaluate whether Er:YAG laser-assisted regenerative surgical therapy can decrease bacterial load and alter microbial profile~Specific Aim 3: To analyze whether Er:YAG laser-assisted regenerative surgical therapy can impact the molecular profile of the peri-implant crevicular fluid (PICF) and the stability of the treatment
The purpose of the study is to evaluate if using Erbium-doped yttrium aluminium garnet laser, Erbium YAG laser (Er:YAG) laser could have adjunctive benefits to the conventional standard mechanical debridement to ablate the infected tissue around the dental implant and detoxify the contaminated implant surface for resolving peri-implant infection and enhance bone regeneration of peri-implant defects.
