The patient, a 61-year-old male in good overall health, presented with two dental implants at positions 14 and 16, supporting a fixed dental bridge. Examination revealed movement in both vertical and horizontal dimensions, whereas peri-implantitis was indicated, with vertical bone loss up to half the height of implant 14, and implant 16 located in the right maxillary sinus surrounded by a large polyp. The dental implants were extracted atraumatically, preserving the Schneiderian membrane. A direct sinus lift with a buccal window was performed, draining and removing the sinus polyp with an aspiration needle. A magnesium membrane was placed on the alveolar bone of the buccal window, with maxgraft^® and cerabone^® granules applied into the buccal window to seal it off from the alveolar bone. Additional graft material was placed in the extraction site and covered with a long piece of magnesium membrane along the alveolar ridge for adequate coverage and separation from the soft tissue. A dental implant was then placed at position 14. Five months post-surgery, the bone displayed optimal hardness and structure. CBCT imaging showed 16–21 mm of newly formed bone, varying by location. Two additional dental implants were subsequently placed at positions 15 and 17.
