Dental Implant Bone Grafting 

Dental bone grafting in San Antonio is offered by Dr. Jeffrey Wert at San Antonio Oral Surgery & Dental Implants. This surgical procedure allows us to help patients grow bone, restoring the functionality and aesthetic appearance of the jawbone.

Periodontal (gum) disease is the leading cause of bone loss in the oral cavity, though there are others such as infections, ill-fitting dentures and facial trauma. A 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. Your surgeon will discuss the options and make recommendations for your specific case. The following are the most common:

  • Autogenous bone graft – In this type of graft the bone is removed from elsewhere in the body and implanted in the mouth. Common donor sites for bone grafting include the iliac section of the pelvis, the chin and the posterior third molar areas of the jaw. If large amounts of bone need to be harvested, the hip or the shin bone (tibia) is generally used.

  • Allograft bone graft -  Allograft bone, like autogenous bone, is derived from humans; the difference is that allograft is harvested from an individual other than the one receiving the graft. Allograft bone is taken from carefully screened cadavers that have donated their bone so that it can be used for living people who are in need of it; it is typically sourced from a bone bank. The advantage is that a second procedure to harvest the patient's own bone can be avoided or lessened.

  • Xenograft – This is the use of bone, other than human origin. The common choices are bovine (cow) bone, porcine (pig) bone and equine (horse) bone. A xenograft is perfectly safe and has been used successfully for many years. Ample bone can be obtained and no secondary donor site is necessary.

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.

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.

What does bone grafting treatment involve?

Bone grafting is a fairly simple procedure which may 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:

  • 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 accellular cementum on the tooth which provides a foundation to allow periodontal attachment to occur. Tissue stimulating proteins help to 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.
  • Bone Morhpogenic Protein - A lab derived protein that induces or caused immature cells to become bone forming cells. These are used in sinus grafting and in large volume grafts, or where compromised healing could occur. 

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