Bone Grafting

Austin Bone Grafting

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 in Anderson Mill 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.

Bone grafts include using either your own bone, synthetic graft materials, or donor graft material.

Reasons for Bone Grafting

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.

What Does Bone Grafting Involve?                                

Bone grafting is a fairly simple procedure that can be performed under local anesthetic.

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:

Gum/bone tissue regeneration – A thin barrier (membrane) is placed below the gum line over the grafting material.  This barrier creates enough space for healthy tissue to grow and separates the faster-growing gum tissue from the slower growing fibers.  This means that bone cells can migrate to the protected area and grow naturally.

Tissue stimulating proteins – Enamel matrix proteins occur during natural tooth development.  Emdogain is a matrix protein product which is usually placed on the affected site before the gum is sutured.  It mediates the formation of acellular cementum on the tooth which provides a foundation to allow periodontal attachment to occur.  Tissue stimulating proteins help create lost support in areas affected by periodontal defects.

Platelet-rich growth factors – A high platelet concentration liquid can be used to create a blood clot at the site of a wound.  It has recently been discovered that PRGF also stimulates bone growth – meaning a denser graft in a shorter time period.

The gum is sutured in place and a follow-up appointment will need to be made within 10-14 days to assess progress. Bone grafting is a highly successful treatment and a good base for further periodontal restorations.

If you have any questions about bone grafting, please ask your dentist.
