Summary
Peri-implantitis are important disease entities as a result of their high prevalence and the lack of a standard mode of therapy. Based on the available data, the non-surgical therapy of peri-implantitis doesn't seem to be effective in disease resolution. Surgical access to peri-implantitis lesions facilitates the removal of all granulation tissue from the defect area as well as a thorough debridement and decontamination of exposed implant surfaces. Numerous approaches have been used for implant surface decontamination during peri-implant surgery, including mechanical, chemical and laser treatments.
