title: The claspless partial denture.
abstract: 1. A simple design for partial dentures has been presented using cobalt samarium (Co5Sm) magnets as both retention and reciprocation units. 2. The magnets are totally enclosed within a thin veneer such as hard dental gold so that the magnet alloy is completely isolated from the oral and tissue fluids. 3. The magnets are arranged in attracting pairs, one member is cemented into a standing abutment tooth while the other member is processed into the denture base directly opposite. 4. Retention is positive, inconspicuous, and oral hygiene problems are minimized.
