Forrest sponge aided sinus membrane lift technique

摘要

The invention involves the use of pre-calculated and preformed, specific forms of medical grade polyurethane foam for sinus membrane surgery by a dentist, physician, or veterinarian, as a non-cutting surgical instrument. The invention uses various shapes to do the job of safely and gently releasing free, predetermined membrane thicknesses of sinus membranes from the boney sinus floor and sinus walls. Sinus surgery is made safer and simpler, even those with a challenging anatomy. The scope of the invention is, therefore, indicated by the claims rather than the foregoing description. Furthermore, the present invention may utilize other specific sponge forms without departing from the spirit of essential characteristics. The forms and shapes and the various sized components are merely exemplary and can be varied to preferred surgical osteotomy and still fall within the scope of the invention. The scope of the invention will be determined only by the claims.
