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 after 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.

Figure 9. Clinical photograph 2 year after the surgery. Note the marginal mucosal recession at the buccal site. Figure 10. Radiographic photograph 2 year after the surgery. Note that the crater-like shape bone loss has changed to a horizontal bone loss pattern and the bottom of the defect has shifted a little upwards.
