A 64-year-old woman has had sign of periimplantitis at #29 (Fig.1 (CBCT sagittatl section)) in the last 3 years. There is bone resorption mesial and distal to the implant at #29 and mesial to the implant at #31 (>; regraft seemingly necessary).
RCT of the tooth #28 is incomplete. A post makes RCT retreatment difficult. In addition, the tooth is free of symptom.
The clearance between the implant at #29 and the Mental Loop (orange) is 2.6 mm. Immediate replacement of the implant with periimplantitis appears to be impossible. Is it true?
