Background: When a tooth is lost the vacant tooth socket collapses as it heals, leaving a toothless area. This collapse causes a loss in both height and width of the surrounding bone. In addition, when a maxillary molar or premolar is lost, the floor of the maxillary sinus expands, which further diminishes the thickness of the underlying bone. Overall, this leads to a loss in volume of bone that is available for implantation of dental implants, which rely on bone integration, to replace missing teeth. A Sinus Lift is often required as a first step when placing a dental implant in the back of the upper jaw. The goal of the sinus lift is to graft extra bone into the maxillary sinus, so more bone is available to support a dental implant. Perforation of the Schneiderian membrane is the most common complication associated with maxillary sinus augmentation procedures with rates ranging from 11% to 56%.Remedies includes stitching the tear or placing a patch. In most cases, the surgery is stopped altogether and the tear is given time to heal, usually six to eight months before grafting can be done again

Technology: With the new technique and device , The Pycisian extends the lateral window if needed, and removesthe remaining membrane.The emergency inflated balloon is then inserted through the lateral window into the sinus , saline is injectedto inflate the ballonand create a new compartment made of a wide net. The net is positioned across the sinus floor and anchored with four tacks to the anterior sinus wall This secure net enables the physician to safely insertand condence the particulate bone graft . When done, The physician simply extracts the saline and further condenses the particulate bone graft.From here on the procedure is carried out as usual, the physician covers the lateral window with collagen membrane and sutures the soft tissue. Over the next eight month a new bone is formed while the balloon and net are slowly absorbed.
