Bone grafting has become a routine procedure in my Charlotte NC practice. As a dentist practicing holistic techniques, I use bone grafting during tooth extractions to promote less contaminated healing. As an implant dentist,often times bone grafting procedures are needed to augment the bone level before an implant can be placed. There are different types of bone graft procedures used for augmentation.
All bone graft materials work the same. Once a graft is placed, the body will gradually replace the graft material with new bone. The only graft material that is not naturally replaced is bone taken from the patient. This is called autogenous bone. For example, bone may be taken from one part of the mouth (donor site) and placed into the site that needs it (recipient site). Autogenous bone remains in the body and blood vessels keep it alive. Autogenous bone is the best type of bone grafting material.
There are many sources for non-autogenous bone grafting materials, and they are divided into three categories:
• Allograft: a bone graft from the same species (another person)
• Xenograft: graft from different species (usually pigs or cows)
• Alloplast: synthetically derived bone (not human or animal)
Non-autogenous bone grafts are usually used to avoid doing a second surgery to retrieve from a donor site. All these graft materials undergo high-level testing and sterilization procedures.
