Severe Mandibular Atrophy Treated With a Subperiosteal Implant and Simultaneous Graft With rhBMP-2 and Mineralized Allograft: A Case Report

Abstract

A 71-year-old patient was successfully rehabilitated by means of a 3D model-derived, hydroxyapatite-coated titanium subperiosteal mandibular implant. The implant was specifically designed to allow bone augmentation. The deficient bone was simultaneously grafted with mineralized bone allograft and recombinant bone morphogenetic protein −2 (rhBMP–2). The 32-month postoperative cone beam computerized tomography follow-up showed vertical bone augmentation beneath the implant frame.
