anterior wall of maxillary sinus as a new autogenic graft source: a case report

This study introduces the anterior wall of the maxillary sinus as a viable and accessible graft site for small to moderate bone defects in the maxilla that pose challenges for implantation. a healthy 40-year-old woman was referred by a prosthodontist due to malpositioned implants. following a comprehensive assessment, the decision was made to remove the implants. upon executing this treatment plan, a medium-sized defect was revealed. the flap was elevated to expose the anterior wall of the maxillary antrum, from which an osseous graft was obtained. this graft was then fixed as a buccal wall of the defect and supported by a membrane. after a healing period of 6 months, two implants were successfully inserted. the anterior wall of the maxillary sinus can serve as a beneficial graft source. however, more extensive studies with appropriate design are required to reach a definitive conclusion.
