  • Title: Implant-supported obturator overdenture for extensive maxillary resection patient: a clinical report.
    Author: Leles CR, Leles JL, de Paula Souza C, Martins RR, Mendonça EF.
    Journal: J Prosthodont; 2010 Apr; 19(3):240-4. PubMed ID: 20040025.
    Abstract:
    This clinical report presents an implant-retained obturator overdenture solution for a Prosthodontic Diagnostic Index Class IV maxillectomy patient with a large oronasal communication and severe facial asymmetry, loss of upper lip and midfacial support, severe impairment of mastication, deglutition, phonetics, and speech intelligibility. Due to insufficient bone support to provide satisfactory zygomaticus implant anchorage, conventional implants were placed in the body of the left zygomatic arch and in the right maxillary tuberosity. Using a modified impression technique, a cobalt-chromium alloy framework with three overdenture attachments was constructed to retain a complete maxillary obturator. Patient-reported functional and quality of life measure outcomes were dramatically improved after treatment and at the two-year follow-up.
