Bone Grafting

Bone grafting is frequently used in connection with dental restorations such as bridge work and dental implants. The height, depth, and width of the jawbone at the implant site can, in the majority of cases, make or break the success of a restoration treatment. The implant(s) cannot be supported on an unstable foundation when the jawbone has retreated or has undergone severe damage, and bone grafting is generally advised for the future rehabilitation.


Jaw bone volume is primarily influenced by a number of factors, including:


  • Periodontal disease – Periodontal disease can harm the jaw bone that supports the teeth and leave it permanently deformed. Affected areas get worse over time, eventually causing the teeth to become unstable.
  • Tooth extraction – According to research, patients who have had a tooth extracted lose between 40 and 60 percent of the bone around the extraction site over the course of the next three years. A “bone defect” is what happens when bone is lost.
  • Infections and injuries – The bone may recede as a result of dental damage, as well as additional physical harm brought on by a hit to the jaw. The jaw bone may also retreat as a result of infections.

Causes for Bone Graft

Most of the time, dental bone grafting is a very successful procedure. Additionally, it is a better option than missing teeth, unhealthy teeth, or deformed teeth. Bone grafting can fill up gaps and flaws in the bone and expand the jawbone’s height or width.


The health and stability of the teeth can be improved by bone grafting in essentially two different ways:


  • Jaw stabilization – For restorative or implant surgery, bone grafting stabilizes and aids in restoring the jaw’s structural base. Additionally, deformities can be fixed, and bone remodelling can add to the support provided.


  • Preservation – Following a tooth extraction, periodontal disease, or other invasive procedures, bone grafting can slow or stop bone recession.

Oral Assessment

In order to determine the overall health of the teeth and gums, the periodontist will first do a comprehensive examination of the afflicted region. Before the bone grafting operation can start, periodontal disease and damaged neighboring teeth will be completely treated. Additionally, the periodontist will advise panoramic x-rays to determine the exact depth and width of the existing bone. 


A CAT scan can sometimes be advised to assess the state of the bones. Depending on these findings, the periodontist may further provide local anesthesia and probe into the gum to ascertain what sort and how much bone is necessary.

What Happens During Bone Grafting?

Dental Bone grafts can be of many sorts. The ideal kind will be chosen for your specific situation by our periodontist. 


  • Autogenous Bone Graft.  extracted from the patient’s body (usually from the posterior part of the lower jaw or the chin). Since it leads in the most predictable outcomes, this procedure is generally preferred.
  • Allograft Bone Grafting.  In this kind of transplant, cadaver or synthetic bone is employed.
  • Xenograft. These grafts are made from cow bone.


It can sometimes take many months to finish the bone grafts surgery. The affected spot is normally filled with bone that has been taken from your own body (or, in rare cases, from a “bone bank”). The migration of cells will result in strong attachment and cell development, and this bone will merge with the old bone. Increased bone mass from adding bone to the jaw will support and anchor the implant by increasing bone mass (s).


The periodontist will use local anesthesia throughout the procedure to numb the grafting and extraction sites. The new bone will be fixed into place after a tiny incision is made to prepare the area. Occasionally, the new bone may be covered with a synthetic membrane. This barrier promotes the formation of new bone while preventing bacterial and soft tissue invasions. You won’t need to spend the night following the procedure, and you’ll get thorough post-op care instructions. The periodontist will recommend medicines to aid with swelling, pain, and infection control.
