This case-based educational module presents the management of a complication in an upper full-arch implant protocol, involving loss of an implant in the left posterior maxilla associated with a residual infectious focus from a previous dental lesion. The case demonstrates the clinical reasoning behind regional anesthesia, flap design, careful palatal and vestibular release incisions, justaperiosteal flap elevation, identification and curettage of residual cystic/infectious tissue, irrigation, and preparation of a new implant bed.

The module emphasizes anatomical awareness in the posterior maxilla, including consideration of the greater palatine neurovascular area and the relationship of the osteotomy to the maxillary sinus. It also discusses implant positioning for prosthetic design, the importance of avoiding excessive palatal or buccal positioning, the use of radiographic verification, subinstrumentation in low-density maxillary bone, and the decision-making process around immediate versus delayed prosthetic capture.

This content is intended for educational review by dental professionals and students interested in implant dentistry, surgical planning, complication management, and prosthetically guided implant placement.
