Bone Grafting
Periodontal disease is the highest 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 effective way to encourage natural bone growth and replace loss bone tissue. Bone grafting is a flexible and predictable procedure which fulfills a various of functions.
For dental implant, a bone graft may be required to create a stable base to halt the progression of gum disease making a smile more aesthetically pleasing.
There are several types of dental bone grafts. The following are the most common:
Reasons for bone grafting
There are a many variety of reasons why bone grafting may be the best option for restoring the jaw bone.
Dental implants – Implants are the favored to replace missing teeth because it allows for restoring full functionality to the mouth; however, the implants needs to be firmly attached to the jawbone to be effective. If the jawbone lacks the crucial quality or quantity of bone, bone grafting can strengthen and thicken the implant site.
Sinus lift – A sinus lift helps elevate the sinus membrane and the grafting bone onto the sinus floor making sure that implants is securely placed.
Ridge augmentation – Ridges in the bone can happen due to trauma, injury, birth defects or severe periodontal disease. The bone graft's job is to fill in the ridge and help the jawbone become a uniformed shape.
Nerve re-positioning - If the inferior alveolar nerve needs movement to allow for the placement of implants, bone grafting procedure may be needed. The inferior alveolar nerve controls the feeling and sensation in the lower chin and lip.
What does bone grafting treatment involve?
Bone grafting is a adequately simple procedure which may require under local anesthetic; nonetheless if bigger amounts of bone area need to be grafted, general anesthetic may be required.
To begin for insertion, the grafting material needs to be prepared or harvested. A small incision is made in the gum tissue and then gently separated from the bone. The bone grafting material is then put at the desired site.
The bone regeneration process may be assisted by:
The gum is sewed in place and a follow up appointment will need to be made within 10 days to assess progress. Bone grafting is a very successful treatment and a good base for further periodontal restorations.

There are several types of dental bone grafts. The following are the most common:
- Autogenous bone graft – In this graft the bone is removed from using another part of the body and then implanted in the mouth. The donor sites for bone grafting are usually the iliac section of the pelvis, the posterior third molar areas of the jaw, and the chin. If the patient needs bigger amounts of bone to be harvested, the hip or the shin bone (tibia) is generally used.
- Allograft – Synthetic bones can be created in the labs and used in the bone grafting procedure. Bones can also be obtained from a bone bank (cadaver bone).
- Xenograft – This is the implement of bovine (cow) bone. This is a safe procedure and has been used successfully for many years. Ample bone can be obtained and no secondary donor site is necessary.

The bone regeneration process may be assisted by:
- Gum/bone tissue regeneration – A thin barrier (membrane) is put below the gum line over the grafting material. The barrier makes enough space for healthy tissue to grow and isolates the faster growing gum tissue from the slower growing fibers. This means the bone cells can move to the protected area and naturally grow.
- Tissue stimulating proteins – Enamel matrix proteins happens during natural tooth development. Emdogain is a matrix protein product which is commonly placed on the affected site before the gum is sewed. It resolves the formation of accellular cementum on the tooth which gives a foundation to allow periodontal attachment to happen. Tissue stimulating proteins help to build areas affected by periodontal defects.
- Platelet-rich growth factors –A high concentration liquid of platelet can be utilized to build a blood clot at the site of a wound. PRGF has been recently discovered that it can also stimulates the growth of bone – which means a denser graft in a smaller time period.
