Periodontal disease is the leading cause of bone loss in the oral cavity, though there are others such as ill-fitting dentures and facial trauma. The bone grafting procedure is an excellent way to replace lost bone tissue and encourage natural bone growth. Bone grafting is a versatile and predictable procedure which fulfills a wide variety of functions.
A bone graft may be required to create a stable base for dental implant placement, to halt the progression of gum disease, or to make the smile appear more aesthetically pleasing.
There are several types of dental bone grafts. The following are the most common:
There are a wide variety of reasons why bone grafting may be the best option for restoring the jaw bone.
Dental implants – Implants are the preferred replacement method for missing teeth because they restore full functionality to the mouth; however, implants need to be firmly anchored to the jawbone to be effective. If the jawbone lacks the necessary quality or quantity of bone, bone grafting can strengthen and thicken the implant site.
Sinus lift – A sinus lift entails elevating the sinus membrane and grafting bone onto the sinus floor so that implants can be securely placed.
Ridge augmentation – Ridges in the bone can occur due to trauma, injury, birth defects, or severe periodontal disease. The bone graft is used to fill in the ridge and make the jawbone a uniform shape.
Nerve repositioning - If the inferior alveolar nerve requires movement to allow for the placement of implants, a bone grafting procedure may be required. The inferior alveolar nerve allows feeling and sensation in the lower chin and lip.
Bone grafting is a fairly simple procedure that can be performed under local anesthetic; however, if large amounts of bone area need to be grafted, general anesthetic may be required.
Initially, the grafting material needs to either be harvested or prepared for insertion. A small incision is made in the gum tissue and then gently separated from the bone. The bone grafting material is then placed at the affected site.
The bone regeneration process may be aided by:
The gum is sutured in place and a follow-up appointment will need to be made within 10 days to assess progress. Bone grafting is a highly successful treatment and a good base for further periodontal restorations.
