Effect of various materials on retentive force of C-Clasp

Partially edentulous clinical scenarios have been on the rise when compared to completely edentulous cases in the last fifty years. Retention for the partial dentures has been derived from conventional Co-Cr clasp assemblies. These clasp assemblies have compromised aesthetics. In this study an attempt has been made to develop aesthetically superior flexible resin clasps with adequate retention.We can derive that flexible resin clasp assemblies have a significantly lower mean peak load of dislodgement when compared to that of Co-Cr Clasp assemblies. However the mean peak load of dislodgement of all the flexible resin materials is above the acceptable range of retentive force which enables them to be successfully incorporated into partial dentures along with favorable aesthetics.
