Clasp dental attachments designed to be adapted around and/or rest on and surround natural tooth abutments, which are usually an integral component of an overlay partial denture (i.e., overdenture). These clasps typically have three components: an occlusal rest, a bracing, and a supporting arm; dental clasps are typically metal flexible castings or wires. Custom-made and preformed overdenture clasps made of synthetic thermoplastic (e.g., polymer) materials are also available but less frequently used.
