This was a case of peri-implantitis on augmented sinus area which resulted in removal of fixtures and graft
materials. After thorough debridement, maxillary alveolar bone was reconstructed using a combination of
autogenous bone from mandibular ramus and micromacroporous biphasic calcium phosphate.
Re-implantation was followed by consolidation period of 3 months. 6 years after re-implantation,
reconstructed site shows favorable healing and bone level height without further progression of bone loss. This
study presents a successful outcome of the compromised alveolar bone status after peri-implantitis
occurrence on the sinus augmented area.
