Bone grafting is the process of taking bone tissue from another area of the body of the patient or using special bone grafting material so that it can be transplanted into the jaw bone. This procedure is used to promote bone formation and wound healing. These results are possible because the bone tissue can totally regenerate for as long that it is provided with the right conditions to grow. We, at Clackamas Implant & Oral Surgery Center, mainly utilize this procedure when the jawbone of our patient for dental implants has deteriorated significantly. This technique is also relied upon to repair broken bones due to bone loss.
Benefits of Bone Grafting in Dentistry
Not many people know that missing teeth does not only affect their teeth and gums but their jawbones as well. The jawbone tends to deteriorate because of tooth loss since it has lost its function. It is estimated that the bone loses up to 60% of its volume after three years of undergoing tooth extraction and it continues to lose at least 0.25% every year. Bone grafting procedure greatly benefits people who suffer from bone loss due to loss of teeth.
If this procedure is not available, patients who want to experience the natural feel and look of dental implants but have deteriorated jaw bone cannot have implants. Those who suffer from injury or surgery defects or bone loss because of periodontal disease can also greatly benefit from the results of bone grafting. Moreover, bone graft can improve the function of implants, crowns, and dentures.
Bone Grafts for Dental Implants
Three of the most common types and tissue sources of bone grafting that are most commonly used to prepare the jawbone for dental implants include autograft, allografts, and xenograft. Autograft or autogenous bone grafting involves taking a bone from the patient who is receiving the graft himself. The bone is usually harvested from other areas and transplanted to the jawbone. This grafting greatly lessens the risk of graft rejection since the tissue to be grafted comes from the body of the patient himself. Allograft is also obtained from humans, but not from the same patient who will be undergoing the bone graft procedure. Allograft bone is usually sourced from a bone bank. Xenografts, on the other hand, come from non-human sources like bovine.
What Happens During Bone Grafting for Dental Implants
During the bone graft procedure, a piece of bone, sourced from the body of the patient or other sources, is transplanted into the jawbone to promote bone growth. After this process, the patient needs to wait for a couple of months until the transplanted bone results in a new bone that is strong and steady enough to support dental implants. Once the jawbone is ready, the metal implants are inserted into the jawbone and given several months again to heal. Once healed, metal posts would then be placed to the dental implant. These metal posts are where replacement teeth would be inserted after the gums have healed.
