Bone Grafting

Bone grafting is a procedure which may be required either after tooth extraction, before dental implant placement (e.g. sinus lift), or during dental implant placement. The main purpose of bone grafting is to preserve or increase the amount of the bone that is present at the surgical site. Bone grafting is commonly completed after tooth extraction or during a sinus lift procedure. After the grafting material is placed it is resorbed by the body and replaced with your natural bone. This will either stabilize or slightly increase the level of bone.

After a tooth is removed and the extraction site is allowed to heal on its own, the vertical height of bone will naturally decrease due to alveolar bone resorption. By placing a bone graft we are able to stabilize the alveolar ridge (the bone that holds the teeth in place). This means that after the tooth extraction site heals the bone height should be similar to pre-extraction levels.

There are 3 types of bone graft material:

1. Autogenous. This comes from the patient.

2. Allograft. This comes from Cadaver.

3. Xenograft. This comes from Bovine, or Porcine.

It is important to mention that numerous steps are taken to eliminate the viral infectivity of the sample.
