A sinus lift, sometimes called a sinusaugmentation, is surgery that adds bone to your upper jaw /maxilla  in thearea of your molars and premolars to have more bone available for yourimplants. The bone is added between your jaw and the maxillary sinuses, whichare on either side of your nose. To make space for the bone, the sinus membranehas to be moved upward, or "lifted."

Why it is done???

 

as age advances the distance between the ridge(bone) & sinus decreases (thinning)A sinus lift is done when there is notenough bone in the upper jaw, or the sinuses are too close to the jaw, fordental implants to be placed. There are several reasons for this:

·                              backteeth, or molars the first ones to appear in the oral cavity may be lost earlyas their exposure to trauma by food,aerated drinks,sweets is more.such earlytooth loss also leads to loss of bone surrounding these teeth which may preventdirect implant to be placed due to lack of bone.

·                              Bonemay have been lost because of diabetes,infections of gums ,herditary causes.

·                              Onceteeth are gone, bone begins to be resorbed (absorbed back into the body). Ifteeth have been missing for a long time, there often is not enough bone left toplace implants.

·                               Theshape and the size of this sinus varies among individuals. 

 

Preparation & Procedures

 

The bone used in a sinus lift may come fromyour own body (autogenous bone) or from a cadaver (allogeneic bone). Syntheticmaterials, which can stimulate bone formation, also are used sometimes. If yourown bone will be used in the sinus lift, it will be taken from other areas ofyour mouth or body. In some cases, the surgeon removes bone from your hip .

You may need ct scans,denta scan X-rays takenbefore your sinus lift so the dentist can study the anatomy of your jaw andsinus. You also may need a special type of computed tomography (CT) scan toaccurately measure the height and width of your existing bone and to evaluatethe health of your sinus.

operative procedure

after the normal local anaesthesia ,the surgeon will cut the gum tissue near your premolars and molars. Thetissue is raised, exposing the bone. A small, oval window is opened in thebone. The membrane lining the sinus on the other side of the window separatesyour sinus from your jaw. This membrane is gently pushed up and away from yourjaw. Granules of bone-graft material are then packed into the space . Theamount of bone used will vary, but usually several millimeters of bone is addedabove the jaw.

Once the bone is placed, the tissue is closed with sutures . if some amount of bone height is available prior tosurgery implants can be placed at the same time under direct vision.in othercircumstances where there is no bone Your implants will be placed four to ninemonths later, depending on the graft material that was used. This allows timefor the grafted material to reorganize with  bone.Your probably will be asked to return a fewmore times to make sure the area is healing properly.After a sinus lift, you need to wait severalmonths for the bony material to harden and integrate with your jaw. Once thishappens, the implants will be placed.
