Bone grafting is often closely associated with dental implants. In the majority of cases, the success of an implant 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. 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.

Reasons for bone grafts

Bone grafting is a highly successful procedure.  Bone grafting can increase the 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:

Restore Bone – Bone grafting helps restore the jaw foundation for  implants and tooth replacement.

Preservation – Bone grafting can be used to limit or prevent bone recession following a tooth extraction, or periodontal disease.

Oral Examination

Initially, Dr. Davidson will thoroughly examine the affected area in order to assess the general condition of the teeth and gums. If periodontal disease is present or the adjacent teeth are in poor condition, these factors will be fully addressed before the bone grafting procedure can begin. 

What Does Bone Grafting Involve?

There are several types of bone grafts. Dr. Davidson will discuss the pros and cons of each type for your mouth.

Allograft Bone Graft - Human donor bone or synthetic bone is used in this type of graft.

Xenograft - Cow bone is used in this type of graft.

Autogenous Bone Graft - Harvested from the patient’s own body (usually from the posterior part of the lower jaw or the chin). 

The new bone takes several months to harden and fuse with the existing bone. Supplementing the jaw with bone will result in greater bone mass to help support and anchor the implant(s).

On occasion, a synthetic membrane may be used to cover the new bone. This membrane 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. Davidson will prescribe medications to help eliminate or reduce infection, discomfort and swelling.
