Augmentation of the floor of the maxillary sinus is an extremely important technique for posterior site development in the maxilla prior to implant placement. A number of techniques have been suggested and used in the past to deal with membrane perforations such as suturing the membrane, application of fibrin sealants oxidized regenerated cellulose and collagen membranes. The most important aspect of sinus grafting is the integrity of the sinus membrane solely to confine the graft. If membrane tears are not taken care of, graft material can extravasate into the antrum and block the ostium. The fast-resorbing membranes are not good enough to form bone as their integrity is lost before woven bone forms. The novel technique demonstrates the use of a slow-resorbing membrane not only for perforations, but even in circumstances where the sinus is devoid of a membrane, thus bypassing the waiting period for schnederian membrane regeneration prior to grafting.
