This case highlights a novel approach to managing failing implant in the maxillary posterior region, emphasizing simultaneous of removal, immediate placement and bone reconstruction by guided regeneration (GBR). A 39-year-old male presented with at position #15 due peri-implantitis, characterized bleeding on probing, suppuration, inflammation, probing pocket depths (PPD) up 9 mm. Radiographic assessment revealed significant periimplant loss, only 4 mm residual osseointegration. Pre-surgical 3D planning ensured precise positioning, avoiding sinus perforation optimizing stability. During surgery, was removed using minimally traumatic techniques, new tissue-level immediately placed, achieving primary stability torque 27 Ncm. The circumferential defect treated deproteinized bovine mineral combined hyaluronic acid covered resorbable collagen membrane initiate reconstruction. site submerged, healing uneventful. Three months post- uncovered, screw-retained monolithic zirconia crown restoring masticatory function esthetics. At 12-months follow-up appointment patient healthy no remaining defect. achieved successful osseointegration, clinical radiographic improvements after 12 months. potential protocol resolution peri-implantitis use sterile implant.
