Reconstruction of advanced mandibular resorption with both subperiosteal and root-form implants

A combination implant reconstruction using both subperiosteal and endosseous root-form implants for advanced mandibular resorption is presented. In theory and practice, physiologic endosseous implant support should prevent further resorption in the mandibular symphysis region. Three patients' post-treatment outcomes demonstrate a complete return of mandibular oral function. The greater risk of mandibular fracture, which is associated with other treatment options (multiple root-form implants or transmandibular implants), is avoided with this treatment approach. With follow-up periods ranging from 6 months to 28 months the three patients are satisfied with comfort, function, and appearance. A long-term follow-up study is planned for future publication.
