title: A locking endurance test for hinged sections of removable partial dentures.
abstract: In this study an apparatus is described that will open and close a hinged section of a removable partial denture. A metal framework based on a "swinglock" type of hinge and latch design was constructed. An electric motor provided the drive for the opening and closing mechanism, which when operated set the device in motion. The device and results of a test run of 12,000 opening and closing operations are discussed.
