Bone Grafting and Sinus Lifts in Newport Beach
When teeth or lost or extracted, or in the case of severe gum disease, bone loss in the jaws occurs. In the first year after a tooth is lost and left un-replaced, 25% of the bone where the tooth used to be is reabsorbed into the body. This bone loss continues and can be made worse by gum disease or wearing dentures.
Bone Grafting and Sinus Lifts for Dental Implants
For certain procedures such as dental implants and dental implant bridges, it may be necessary to augment the jawbone through bone grafting or sinus lifts, a technique to add bone to an expanded sinus cavity. These techniques prepare a site in the jaw for implants by ensuring there is sufficient bone volume. This permits the dental implants to become fully integrated into the jawbone.
As a prosthodontist who has completed a surgical fellowship in implant dentistry, Dr. Amini is an expert in oral rehabilitation procedures including bone grafting and sinus lifts. In his career, he has placed over 2000 implants and has performed many bone augmentation procedures. He uses high-quality materials in order to ensure a successful outcome.
A bone graft is human, bovine or synthetic bone tissue that is placed on a bone that needs augmentation (an increase in volume). Dr. Amini determines on a case-by-case basis which graft type will work best for you. The bone graft is added to the existing bone and it also stimulates the jawbone to grow more bone on its own.
As an effective bone grafting technique, Dr. Amini performs guided bone regeneration (GBR), which is the use of membranes to serve as barriers that allow new bone to be generated without interference from the cells of other tissues in the mouth. Titanium-reinforced membranes may be used to help to hold the shape of the bone while the bone graft material and jawbone work to grow new bone.
Dr. Amini is capable of performing complex grafting techniques that make use of the latest innovations in his field. He ensures that the bone graft materials he uses are of the highest quality and have solid studies and a good track record behind them before using them in his practice.
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 healing period varies from patient to patient and typically lasts three months. Dr. Amini usually can place the bone graft at the same time that he places the implant.
A sinus lift is done when there isn’t enough bone volume in the upper jaw to accommodate and support a dental implant or when the sinus is too close to the jaw for implants to be placed.
Bone can be lost through gum disease, or it can get reabsorbed back into the body after the loss of a tooth because the jawbone loses the stimulus of the chewing tooth.
Some patients have enlarged sinuses, which could have many causes. For instance, a patient’s sinus may have become enlarged with age, or a patient may have naturally enlarged 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.
A sinus lift is performed by gently lifting the membrane separating the sinus from the jaw. Bone graft material is then packed into the space left behind 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.
