When a patient loses a tooth, the bone around that tooth begins to deteriorate and shrink away, limiting surrounding tooth function and ability for future tooth replacement options. A bone graft is a surgical procedure that replaces missing bone with an artificial, synthetic, or natural substitute. The graft provides a sub-structure for your body to regenerate its own bone in the area. Bone grafting is often performed to ensure that a patient will have sufficient bone for future replacement of missing teeth. Without sufficient bone structure, options such as implants may not be possible. Also, sufficient bone is necessary for fit and retention in dentures and partial dentures and other dental services.
