  • Rubber dam clamp
    Patent number: 5713737
    Abstract: The rubber dam clamp is made of fiber-reinforced plastic. The dam clamp has a pair of gripping claws that are adapted to engage a tooth neck. A resilient bridge connects the gripping claws. A pair of open sockets are defined in an inside of the gripping claws between the bridge and the gripping claws. The sockets are adapted to receive the points of a rubber dam clamp forceps so that the dam clamp may be opened without the risk of the forceps being caught in the socket when the dam clamp is released and the forceps is to be removed therefrom.
