Abstract

The purpose of this study was to evaluate retentive force of cobalt- chromium (Co-Cr) and nano-gold (AuNps) reinforced flexible clasps in Kennedy class I removable partial denture (RPD). Acrylic model represented Kennedy class I partially edentulous maxillary arch was fabricated and prepared for RPD fabrication. Traditional Co-Cr RPDs with gingivally approaching retentive clasp arm, thermopress flexible polymeric and AuNps reinforced thermopress flexible polymeric RPDs with circumferential retentive clasp arm were fabricated. Retentive force of RPDs were evaluated. The flexible polyamide and reinforced flexible RPDs revealed better preservation of retentive force rather than Co-Cr RPDs that showed a decrease in magnitudes after repetitive cycles.
