Sinus lift alloplast (a growth-factor infused collagen matrix), synthetic variants, or combinations thereof. Studies indicate that the mere lifting of the sinus membrane, creation of a void space and blood clot formation might result in new bone owing to the principles of guided bone regeneration. The long-term prognosis for the technique is estimated to 94%. As an alternative, sinus augmentation can be performed by a less invasive osteotome technique. There are several variations of this technique and all originate from the original technique of Dr. Tatum, first published by Dr.s Boyne and James in 1980. Dr. Robert B. Summers described a technique
