Bone Grafting and Sinus Lifts in Sunnyvale

Bone Grafting and Sinus LiftsBone loss can occur as a result of loss or extraction of teeth, or if there has been severe gum disease. In the first year after a tooth is lost, 25% of the bone where the tooth is missing is reabsorbed into the body. This bone loss is continued, and can be accelerated by denture wearing and gum disease.

Bone grafting and sinus lifts for dental implants

For certain procedures such as dental implants and dental bridges, it can be necessary to augment the jawbone. Bone grafting and sinus lifts are commonly used techniques for preparing a site for dental implants, as implants require sufficient bone height in order to be fully integrated for maximum support.

Our periodontist, Dr. Scott Dault, takes care of our patients’ bone augmentation needs. A periodontist is a specialist with several years extra training in dental implants and bone and gum treatment and is the most equipped to treat patients for bone loss.

Bone Grafting

Bone Graft (Socket Preservation)

A bone graft consists of human, bovine or synthetic bone tissue that is placed on the bone needing augmentation. Dr. Dault assesses which graft material will work best for the patient. In general, he has found that bone graft material of human origin as well as certain synthetic materials work best.

The bone graft adds to the existing bone as well as stimulating the bone to grow more bone.

Bone grafts and Dental Implants

Bone grafts are performed using local anesthesia. Once the bone graft has fully integrated with the bone the implant can be placed. This can take about three months.  If you only need a minor graft, the bone graft can be placed at the same time as placing the implant.

Sinus Lifts

Sinus Lifts

A sinus lift is done when there is not enough depth of bone in upper jaw to accommodate and support a dental implant or when the sinus is too close to the jaw for implants to be placed.

There are various reasons for an enlarged sinus. Sinuses can become enlarged with age or some people have inherently large sinuses. In cases where the upper back teeth have come out, sinuses tend to expand. The upper jaw also has naturally less bone than the lower jaw, especially in the area of the back teeth.

Bone can be lost through gum disease or when teeth are lost. Once teeth are gone the jawbone underneath loses the stimulus of the chewing teeth and the bone reabsorbs back into the body.

A sinus lift is performed by gently lifting the membrane separating the sinus from your jaw. Bone graft material is then packed into the space left by the sinus. Usually several millimeters of bone is added. Once the new bone has fully integrated with your jawbone the implant can be placed.
