Theoretical Role of Adjunctive Implant Positional Support in Stress Distribution of Distal-Extension Mandibular Removable Partial Dentures

This preliminary study evaluated the adjunctive supporting role of diverse implant positions on stress distribution in a Class I removable partial denture (RPD) design. Nine three-dimensional finite element models were prepared to simulate mandibular RPD designs with three different loading conditions applied. Implantsupported designs demonstrated lower stress value concentrations and mucosal displacement.
