When there is loss of jaw bone, dental surgeons can restore it with the procedure called bone grafting. The bone loss may be a result of a periodontal disease, tooth removal, trauma, cyst, or long-term tooth loss. Though human body cannot grow new bone on its own, bone grafting can help with replacing missing bone, fill in pockets of bone loss and stimulate new bone growth. Bone grafting can be described as a procedure where person’s bone is grafted from one place to another.
Bone grafts are often necessary for dental implants, as they are used for additional support when natural bone has deteriorated. There are different types of grafts, and believe it or not a graft can be taken even from animals (usually from pigs). There are synthetic grafts as well.
Bone can be grafted with small specially shaped plates and blocks, or defects can be filled with very small blended pieces. Blended mix is used to fill irregular shapes, while plates and blocks are used where more shaped defect is needed to be filled. Special membrane is always placed oved, between graft and soft tissue, for securing proper healing.
Size and type of a graft depend on the case and what doctor thinks will work best. Once tooth is removed and implant is not placed right away the jaw bone usually shrinks and the result is often significant bone loss. This bone loss is not the person’s fault, it’s the natural resorption process that typically causes the bone to deteriorate. In order to have a dental implant placed, there needs to be more bone to anchor the implant. There are several ways to recompense the missing bone so that jaw would be able to accept the dental implant. These are called bone grafting techniques.
Socket grafting is bone added at the time of tooth removal. The tooth would be removed and the bone grafting material would be placed in the hole left after removing the tooth. After that four months of healing begins. When healing time passes, it is time for implant to be placed along with the crown and thereby allowing final restoration to take place.
If sinus lift procedure is necessary, additional artificial bone is placed under maxillary sinus, pushing it up and providing the area more bone surface. Implant can now easily fit and without any concerns about stability and longevity. Bone grafting is safe, routine procedure, made to provide enough amount of bone to place implants and fill defects. With very low risks, its success is improved constantly with new technology and researches.
