sinus augmentation or sinus procedure is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placing a bone graft

When a tooth is lost the alveolar process begins to remodel. The vacant tooth socket collapses as it heals leaving an edentulous (toothless) area, termed a ridge. 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 osseointegration (bone integration), to replace missing teeth. 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.

There are multiple ways to perform sinus augmentation. The procedure is performed from inside the patient’s mouth where the surgeon makes an incision into the gum, or gingiva. Once the incision is made, the surgeon then pulls back the gum tissue, exposing the lateral boney wall of the sinus. The surgeon then cuts a "window" to the sinus, which is exposing a the Schneiderian membrane. The membrane is separated from the bone, and bone graft material is placed into the newly created space. The gums are then sutured close and the graft is left to heal for 4–12 months.

The graft material used can be either an autograft, an allograft, a xenograft, an 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.

In some cases the dental implant is also inserted during the same sinus lift procedure.

Sinus Augmentation

THis operation is provided by ACE fo Surgical Dental tools & Materials.
This include opening a window in the sinus wall without cutting the lining membrane & then lift the bony window & put Hydroxyapetite bone subistitute, This transvert into bone & by this method we provided sufficient bone for any implant supported dental prosthses.

After upper posterior teeth are lost the maxillary sinus cavity has a tendency to pneumatize or "bubble down" and the molar extraction site alveolar bone starts to atrophy. This results in a situation where there can be inadequate bone height to place a dental implant. There is a common procedure that can be done to create additional bone height and result in an adequate receptive site to place a tooth implant and return the option of having attached permanent teeth again. Otherwise, the patient would be relegated to wearing a removable partial or having a dental bridge.
