A Case Report of a 2-Year Follow-up of Minimally Invasive Surgery in Peri-implantitis: Peri-implant Excisional Procedure and Access Surgery (PEAS)

This case report describes the treatment of peri-implantitis lesions through a minimally invasive surgical procedure using a peri-implant excisional procedure and access surgery (PEAS). The prosthesis was disconnected and the peri-implant granulation tissue removed following a peri-implant circular incision. Chemical debridement with hydrogen peroxide on a cotton ball and then mechanical debridement with a rotary round titanium brush and tufted brush with titanium bristles were conducted. The surgical intervention was effective in arresting the peri-implantitis. No further radiographic bone loss was observed over the 2-year follow-up period. This technique effectively cleans the contaminated implant surface, minimizes surgical morbidity and allows for prosthesis delivery on the day of surgery. However, further studies with a larger sample size are needed to identify the reliability and validity of this novel technique.
