Bone grafting for dental implants can be performed in each of our office locations including Ann Arbor, Plymouth, Adrian, and Dexter, MI.
What is bone grafting?
Bone grafting is an oral surgery procedure that enables us to promote new bone growth where the jaw bone may be sparse or of poor quality due to atrophy. In most cases, the bone structure in the jaw weakens over time if missing teeth aren’t replaced promptly. This often leads to poor bone quality and degeneration, making the jaw unsuitable for the placement of dental implants. Lack of bone to support dental implants can be treated with a bone grafting procedure. Bone grafting can restore missing bone to provide proper jaw bone shape and volume for the placement of healthy and aesthetically pleasing dental implants. The specialized training of our oral surgeons uniquely qualifies them to perform these grafting procedures. Depending on the type of reconstruction required, bone grafting may use bone from the patient’s own jaw or from a tissue bank. Most bone deficits can be successfully treated with grafting. There are several types of grafting procedures available depending on what type of bone restoration is needed:
- Socket preservation
- Sinus grafting (sinus lift)
- Onlay grafting
Having the right amount of bone to support the implant is critical to the success of the treatment. When a tooth is removed, normal healing and disuse of the area will lead to shrinkage of the bone in the immediate vicinity of the extracted tooth or teeth. Socket preservation preserves and restores the normal bone shape that surrounds the tooth to be extracted. The procedure involves filling the socket with bone granules immediately after the tooth is removed. This bone is usually from a tissue bank and is completely replaced by your own bone in about four months. The end result is the maintenance of the normal anatomy of the bone that, in turn, will provide a better site for implant placement. If you are anticipating having an implant to replace a tooth that you are about to have extracted, socket preservation is often recommended. This is a simple procedure that our doctors can perform for you and does not prolong treatment or recovery time.
If you are missing upper molars, it may be necessary to build up the bone in the sinus area. The maxillary sinuses gradually enlarge over time and encroach upon the roots of the upper molar and bicuspid teeth. To provide enough bone to support implants, a sinus graft or sinus lift procedure may be recommended. This graft lifts up the sinus membrane allowing the bone to be placed adjacent to the sinus floor directly above the implant sites. This bone is allowed to heal for about four months before placing the implants. In some cases, the implant may be placed at the same time as the sinus graft. This is a common procedure and can be performed either under local anesthesia or intravenous sedation to enable implant placement in the upper back jaw region.
When bone is lost due to trauma, infection, or shrinkage due to denture use, onlay or block grafting is often used to restore the bone before implant placement. The block refers to the shape of bone used. Unlike the sinus graft that uses granular bone from a tissue bank, this bone may be obtained from the lower jaw of the patient. The bone is then transferred to the site to be reconstructed and secured in place. Four months of healing is allowed before implant placement. The donor site heals well and does not weaken or change the shape of the jaw or face. Large defects may require the collection of bone from more than one area of the jaw or, in situations where there is extensive bone loss, it may be necessary to harvest bone from the hip. Our oral surgeons have the training and experience to perform all types of grafting procedures to facilitate your implant treatment.
Dr. Fear, Dr. Lopez, Dr. Fasi, or Dr. Sanker will complete a thorough oral examination and X-ray evaluation of your gums, teeth, and jaws to determine if you need a bone grafting procedure. They will discuss your options for jaw bone repair so that you are fully informed on which bone grafting technique will provide you the best possible outcome. Each bone graft option has its own set of benefits and risks, which is why we work closely with our patients to develop a plan for jaw bone repair that will restore both aesthetics and oral function to the mouth.
