I have a patient who presents with an implant of unknown brand placed 15 years ago which currently has peri-implantitis. The patient wants the old cement retained PFM replaced with a Zirconia crown and Zirconia abutment. The implant has crescent shaped bone loss to the middle third. The CBCT scan shows a fenestration towards the buccal surface near the apex. To treat the peri-implantitis I plan to debride and place a bone graft with GBR. I am unsure how to proceed with the prosthetic challenges of an unknown implant system. Can anybody identify the implant used? Can you recommend a course of prothetic treatment for the abutment and crown?
