Abstract

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.
