The alveolar crest is the most coronal portion, or the top, of the alveolar process. It is an extension of both the mandible and maxilla and holds the tooth sockets. The alveolar crest is often the first portion of the alveolar process that is damaged by periodontal disease and is therefore the first bone that is lost. The loss of bone at the alveolar crest can prevent a dental implant from achieving long-term success as the bone will not have the density or stability required to support the implant or prosthesis. For patients who have suffered a significant amount of alveolar bone resorption, an alveolar bone graft will be required to build-up the alveolar crest. This type of bone graft will not only provide the tissue required for implant osseointegration but will also add strength and density for the support of implant hardware. To assist in the preservation of the natural alveolar bone, good dental hygiene should be consistently maintained.
