Closure of a 1.5-cm oral antral fistula was done in combination with sinus floor and extraction socket grafting using recombinant human bone morphogenetic protein-2 within a collagen sponge matrix. The approach to the sinus was transalveolar, with elevation of the sinus membrane done through a molar extraction socket. Following graft placement, soft tissue repair was done with a buccal advancement flap. A dental implant was subsequently placed and restored. Peri-implant bone and implant stability were well maintained at the 1-year follow up examination.
