What Happens During a Sinus Lift?

November 2nd, 2015 by

A sinus lift is a procedure done at the Dental Implant Group London, which aims to improve the structure of the upper jaw bone, particularly in the area where the molars and premolars are located. Also called sinus grafting or sinus augmentation, this procedure is done prior to a dental implant treatment – when the upper jaw bone area lacks sufficient structure to support the placement of the implants. The technique is called a “lift” because it involves moving the sinus membrane upward, to clear enough space for the placement of the bone material.

The material for the sinus lift may come from your own body. In this case, the bone may be harvested from your mouth or hip areas. Prior to the procedure, diagnostics such as X-rays and/or CT scans may be obtained to be enable the dentist to have a clearer view of your upper jawbone structure, and to see into the sinus area so that the existing bone’s width and height can be measured accurately.

During the procedure, the dentist or oral surgeon will make an incision in the gums where premolars and molars are located. The gum flap is lifted to expose the jawbone underneath, providing access to the sinus membrane, which will then be moved gently upward away from the jaw. The resulting space will be filled with the bone grafting material, and will then be secured in placed by stitching the gums closed. The bone material will be given enough time to integrate with the surrounding bone tissue before dental implants can be attached.
