What is Bone Grafting?
An autogenous bone graft involves transplanting your own bone to replace tissue that has disappeared. Bone is taken from the lower jaw or the patient’s chin and is transferred to the recipient site where there is a bone deficit. This procedure is applicable when the alveolar process is deformed, that is when its width or height is reduced, and the tooth implantation procedure is not possible.
Reasons leading to bone loss:
- tooth loss – if there is no tooth performing its function in the alveolar, the destruction process begins in its place;
- periodontal disease – dental plaque as well as calculus lead to the multiplication of pathogenic microorganisms, which leads to the destruction of bone tissue around the tooth, and may even contribute to its loss;
- injury – the injured person loses a tooth, as well as the surrounding tissue;
- using removable dentures – when using removable dentures, bone tissue atrophy inevitably progresses.
When is bone grafting performed?
Our highly skilled dentist, Dr. Van de Vyver, utilizing an innovative cone beam computed tomography (CBCT), assesses the quality and volume of the bone base. If the dimensions are not sufficient, one solution is to perform a bone graft. The transplant can be completed in any place of the alveolar process using modern surgical methods.
Is it worth it?
If the bone tissue is deformed due to tooth loss and implantation is planned, this method provides outstanding results in bone reconstruction. A less complicated approach, such as guided bone regeneration, in which bone substitutes are used, can often be circumvented. But there are cases where an autogenous bone grafting is required.
What can I expect during a Bone Grafting procedure?
Due to its duration (the procedure lasts from 1.5 to 3 hours), bone grafting is performed under intravenous sedation or, if applicable, under the use of local anesthesia. So the patient is relaxed, and the procedure is painless. First, the doctor cuts the soft tissues to see and evaluate the bone, then takes the bone block from the previously selected and delaminated area, moves it to the recipient site, and attaches the sample with special screws. If required, the grafted bone is covered with bone substitute material and a membrane. The wounds are then stitched.
What is happening at the site where the bone was taken?
At the site where the bone was taken for a transplant, a clot forms, and new bone begins to form. About 70% of the bone volume is regenerated. If a large fragment has been collected, the newly formed bone loss is filled with bone substitutes in order to restore as much of the lost tissue as possible. If necessary, bone fragments can be retrieved from the same site after seven to nine months.
What happens after the treatment?
After the surgery, the anesthesia stops working, and the patient may feel slight pain. Tissue swelling will appear, typically the greatest on the third day after the surgery. After the bone grafting procedure, Dr. Van de Vyver prescribes an antibiotic to protect the wound from infection and appropriate painkillers to ease any pain and discomfort. In seven to ten days, the patient should follow-up to have the stitches removed. The implant can be installed after about four months following the bone grafting procedure, and the abutment can be installed after another four months.
After bone grafting, you should avoid smoking as it worsens the outcome of the surgery. A few days following the treatment, you should limit your activities, avoid sports and sauna.
As with other procedures involving surgical intervention, contraindications to bone grafting exist, which may include:
- heavy smoking habits;
- Uncontrolled and untreated diabetes;
- chronic diseases of connective tissue that disturb the blood supply to the tissues.
