FLEXIBILITY OF THE RETENTIVE ARM OF ACETAL RESIN CLASP VERSUS CAST CLASPS- AN IN VITRO STUDY

Abstract

Restoration of esthetics is an important factor to consider in the fabrication of a removable partial denture (RPD) . 1 Several types of polymers and metal alloys have been used in RPD construction. Frequently, RPD clasps made from the same alloy as the metal framework. The most common alloys used for clasps are cobalt-chromium (Co-Cr) alloy and gold and titanium alloys, although these may be unesthetic. 2 Some strategies can be used to optimize aesthetic results in RPDs, such as attachment systems 3 RPD with a rotational path of insertion, 4 aesthetic clasp designs 5
