Teeth are anchored into the jaw in an area of the bone called the alveolar ridge. The alveolar ridge bone surrounds tooth roots to secure teeth and allows for normal tooth use such as chewing.nnWithout enough alveolar ridge bone, the jaw cannot support either natural teeth or dental implants. There are many reasons why you may have lost bone in your jaw. For example, you may have had either a tooth knocked out and bone was lost with the tooth, or you may have periodontal (gum) disease. For whatever reason, you may not have enough bone in your jaws to anchor your natural teeth or to support the successful placement of dental implants.nnIf you have lost alveolar ridge bone, and need to re-grow the bone to place dental implants, your surgeon may recommend that you have bone graft surgery. INFUSE Bone Graft may be an option.
