Bone Grafting

Bone Grafting Santa Monica - Type of Bone Grafts 

Jawbone loss can cause significant aesthetic changes and oral health issues. To help restore bone that has been lost as a result of tooth loss, gum disease, or trauma, our team of periodontists provides dental bone graft procedures at our Santa Monica office. This treatment restores bone tissue, rebuilding a strong foundation for restorative work such as dental implants or full mouth reconstruction. With over 40 years of combined experience, our periodontists are widely recognized as the top bone grafting specialists in Santa Monica and use multiple techniques for performing bone grafts to provide you with the unique results you need.

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:

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 surrounding area, the chin and the posterior third molar areas of the jaw. 

Allograft –  Bone can also be obtained from a bone bank (cadaver bone). Synthetic bone (manmade) can be created in the laboratory and used in the bone grafting procedure.

Xenograft – This is the implantation of bovine (cow) bone. A xenograft is perfectly safe and has been used successfully; ample bone can be obtained, and a secondary donor site is not 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.

Bony Pockets - Bony Pockets around the teeth can be regenerated with bone grafts.

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.

Sinus lift – A sinus lift entails elevating the sinus membrane and grafting bone onto the sinus floor so that implants can be securely placed.

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.

 

What does bone grafting treatment involve?

Bone grafting is a fairly simple procedure that can be performed under local anesthetic; however, if large amounts of bone need to be grafted, sedation 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 create lost support in areas affected by periodontal defects.

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.
