Abstract
A sinus correction method is disclosed. For example, one embodiment comprises making an incision in gingival tissue surrounding a sinus membrane perforation, dissecting the gingival tissue from cortical bone, dissecting sinus membrane adjacent to the gingival tissue from the cortical bone, overlapping the sinus membrane and adjacent gingival tissue from two sides of the sinus membrane perforation, connecting the overlapping sinus membrane and adjacent gingival tissue from two sides of the sinus membrane perforation, and applying a bone graft composition adjacent to the overlapping sinus membrane, the bone graft composition to form bone connected with cortical bone sufficient to place a dental implant.
