US Classification:

Abstract:
Disclosed methods and apparatus for removing a dental restoration from a tooth provide an aperture in the restoration and establish part of the restoration at the aperture as a shelf facing in the direction of the tooth. A force acting on the shelf relative to and away from the tooth is established at the provided aperture and the restoration is removed from the tooth with the force. In practice, the shelf may be established by undercutting the restoration at the aperture.
