How are bone grafting & GBR procedures performed?
The following is one example of these procedures following tooth extraction.
1. The tooth is removed and the remaining tooth socket is thoroughly cleaned of all inflamed and infected
tissue.
2. An appropriate bone grafting material is carefully placed into the extraction socket.
3. GBR membrane is often placed over the grafted material.
4. Sutures placed into the gum tissue allow proper healing of the surrounding soft tissues.
Are bone grafting & GBR painful procedures?
These procedures are usually done in the doctor’s office under local anesthesia or local anesthesia with
I.V. sedation or occasionally general anesthesia. The procedures themselves are without pain.
Post-operatively, there will be some swelling and some mild to moderate discomfort, especially from other
procedures performed, such as tooth extraction, cyst removal, etc. Your doctor will prescribe an oral
analgesic to help relieve your discomfort. If a more invasive second procedure is required to obtain bone
(i.e. from your hip, chin area, etc.) then your post-operative discomfort will be increased but still
manageable.
What special care is required after my grafting procedure?
Generally, the same prudent care required after any dental surgical procedure will be sufficient following
jaw bone grafting & GBR. The area must be kept clean, often with the help of a prescribed mouth rinse. An
antibiotic, if prescribed by your doctor, must be taken. Antibiotics, however, are not always required.
Undue pressure over the grafted site must be avoided until the new bone is well on its way to being formed.
This means that previous dental prostheses, such as a removable full or partial denture, must be altered by
your dentist following the grafting procedure. And finally, brush and floss your teeth as you normally do.
However, avoid the gum tissues surrounding the bone graft until they are well healed (usually about six
weeks).
How successful are bone grafting & GBR?
Recent advances in technology have dramatically increased the success of these procedures, leading to bone
formation and resolution of the defect. However, depending upon the reason needed for these procedures,
success rates will vary. Also, different graft & GBR materials seem to affect the amount of new bone formed.
And finally, your own overall health will also help determine the degree to which new bone will form within
the grafted site.
Are there different types of bone grafts & GBR membranes?
Yes. Some grafts are taken from different parts of the patient’s own body (i.e. from the hip bone or chin).
Other grafts come from deceased human organ donors, from synthetic materials, and from highly purified bone
minerals. Likewise, there are different types of GBR membranes. Some are made from synthetic polymers and
must be removed during a second surgery several weeks or months later. Others are made from natural
materials and are gradually resorbed (melt away) by the body.
What type of grafts are used at your office?
We use Bio-Oss which is a safe, effective bone grafting material from specialty processed bovine sources.
Under the electron microscope, Bio-Oss looks very similar to human bone. Because of its similarity to human
bone, Bio-Oss is highly successful in helping new bone to form. In many cases, using Bio-Oss eliminates the
need for additional surgery to obtain your own bone as grafting material.
