Bone and sinus grafting are surgical procedures used to fix or replace bone in the mouth that has been damaged or lost. Patients who have lost a lot of bone because of periodontal disease, an injury, or taking out a tooth may need these procedures.

There are several reasons why someone may need a bone or sinus graft:

• To support dental implants: To succeed, there must be enough healthy bone in the jaw to keep them. If there is not enough bone, a bone graft can be used to build the bone to a sufficient level.
• To repair bone loss: Bone loss can occur due to various factors, such as gum disease, injury, or infection. A bone graft can help to rebuild the lost bone and restore the structure and function of the mouth.
• To fill in gaps or defects: A sinus lift, or sinus graft, is a procedure that is used to add bone to the upper jaw, near the molars and premolars. This procedure is often necessary when the sinuses are too close to the jawbone to place dental implants.
