Cast and wrought wire clasps for removable partial dentures
Cosmetic dentures are used popularly nowadays, removable partial dentures usually consist of replacement teeth attached to pink or gum-colored plastic bases. A partial denture may have a metal framework and clasps that connect to your teeth, or they can have other connectors that are more natural looking.
A set of guidelines for the selection of cast and wrought-wire clasps for removable partial dentures suggested that combinations of clasp material and undercut that would exert the maximum retentive force without deformation were the most effective, as published in the International Dental Journal. The results provide valid guidelines for the use of combinations of clasp material and undercut that would exert the maximum retentive force without deformation for both short (premolar) as well as long (molar) clasps, for wrought and cast clasps.
