title: The sinus lift procedure: an alternative to the maxillary subperiosteal implant.
abstract: Technical advances now allow implants to be placed when pneumatization of the sinus has left insufficient bone to engage an endosseus implant. Augmenting material, such as a mixture of resorbable hydroxylapatite and demineralized freeze-dried bone, is grafted into the sinus cavity. This creates a new alveolar ridge to support endosseous implants.
