Bone grafting is often closely associated with dental restorations such as bridge work and dental implants. In the majority of cases, the success of a restoration procedure can hinge on the height, depth, and width of the jawbone at the implant site. When the jawbone has receded or sustained significant damage, the implant(s) cannot be supported on this unstable foundation and bone grafting is usually recommended for the ensuing restoration.
There are several major factors that affect jaw bone volume:
Periodontal Disease – Periodontal disease can affect and permanently damage the jaw bone that supports the teeth. Affected areas progressively worsen until the teeth become unstable.
Tooth Extraction – Studies have shown that patients who have experienced a tooth extraction subsequently lose 40-60% of the bone surrounding the extraction site during the following three years. Loss of bone results in what is called a “bone defect”.
Injuries and Infections – Dental injuries and other physical injuries resulting from a blow to the jaw can cause the bone to recede. Infections can also cause the jaw bone to recede in a similar way.
Reasons for bone grafts
Bone grafting is a highly successful procedure in most cases. It is also a preferable alternative to having missing teeth, diseased teeth, or tooth deformities. Bone grafting can increase the height or width of the jawbone and fill in voids and defects in the bone.
There are essentially two basic ways in which bone grafting can positively impact the health and stability of the teeth:
Jaw Stabilization – Bone grafting stabilizes and helps restore the jaw foundation for restorative or implant surgery. Deformities can also be corrected and the restructuring of the bone can provide added support.
Preservation – Bone grafting can be used to limit or prevent bone recession following a tooth extraction, periodontal disease, or other invasive processes.
What Does Bone Grafting Involve?
The bone grafting procedure can often take several months to complete. Artificial or modified natural bone is added to the affected site. This bone will fuse with the existing bone and the migration of cells will cause firm adhesion and cell growth. Supplementing the jaw with bone will result in greater bone mass to help support and anchor the implant(s), we well as improve the bone recession associated with tooth loss.
During the surgery, Dr. Prilutsky will numb the grafting and extraction sites using local anesthetic. A small incision may be made to prepare the site for the new bone and it will be anchored into place. On occasion, a synthetic may be used to cover the new bone. This barrier prevents soft tissue and bacterial invasions, and encourages new bone growth. The surgery does not require an overnight stay, and you will be provided with comprehensive instructions for your post-operative care. Dr. Prilutsky will prescribe medications to help manage infection, discomfort and swelling.
