  • Title: Mandibular implant-retained overdenture: a clinical trial of two anchorage systems.
    Author: Menicucci G, Lorenzetti M, Pera P, Preti G.
    Journal: Int J Oral Maxillofac Implants; 1998; 13(6):851-6. PubMed ID: 9857597.
    Abstract:
    This in-vivo study aimed to investigate the load on the working-side implant and on the edentulous distal mucosa of the nonworking side in a mandibular implant-retained overdenture (MIR-OVD) anchored to 2 implants by either a ball- or a clips-and-bar attachment. Three female patients were provided with duplicate dentures anchored in the 2 ways. Strain on the implant was investigated using a strain-gauged abutment, and load on the mucosa was measured using a suitably placed load cell. Ball attachments appeared to provide greater stability to the MIR-OVD, since load was more evenly distributed onto the distal mucosa of both sides. When the MIR-OVD was bar-anchored, axial load on the working-side abutment increased.
