  • Patent number: 4197647
    Abstract: Curved dental pliers particularly suited for removing crowns and other dental prostheses are scissors-like or nut-cracker-like in action, the scissors-like pliers having a pair of fulcral projections to the rear of the pivot joint and the others having a fulcrum at the pivot. The fulcral projections locate a proper fulcral point and provide for proper orientation in the arc of removal. The pliers include interchangeable removable cushioning pads for gripping the dental work without damaging same. A support member for use in conjunction with the pliers provides a firm base for receiving the thrust of the fulcral projections.
