Bone grafting is 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.
In order for Dental Implants to be successful, the jawbone must have enough bone to support them. Many patients do not have enough bone after experiencing tooth loss from Periodontal Disease, injury, trauma or a developmental imperfection.
Bone Grafting is the common procedure that adds bone to the jaw line, before implants can be placed and secured, and in other periodontal procedures involving natural teeth. This works for patients who may have a jaw that is too short, narrow or both.
There are several major factors that affect jaw bone volume:
Reasons for Bone Grafting:
In most cases, Bone Grafting is a highly successful procedure and a great 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 two basic ways in which this 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?
While there are several types of Bone Grafts available, we will determine the best type for your condition.
Autogenous Bone Graft – Harvested from the patient’s own body (usually from the posterior part of the lower jaw or the chin). This method is usually preferred because it produces the most predictable results.
Allograft Bone Graft – Cadaver or synthetic bone is used in this type of graft.
Xenograft – Cow bone is used in this type of graft.
Bone Grafting procedures can take several months to complete. Bone is typically harvested from your own body (or on rare occasions obtained from a “bone bank”) and 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).
During the surgery, the dentist will numb the grafting and extraction sites using local anesthetic. A small incision will be made to prepare the site for the new bone and it will be anchored into place. The surgery does not require an overnight stay, and the patient is provided with comprehensive instructions for your post-operative care.
We can also prescribe medications to help manage infection, discomfort and swelling for the patient.
