Patent ID: 7976308

Claim:
A dental wedge for tight placement into the interproximal space between adjacent teeth during dental reconstruction to hold a matrix band so that it conforms to an anatomical tooth surface of one of said teeth as a result of the device being wedged against the other of said teeth, the dental wedge having an elongate body with a proximal end and a distal end, the elongate body being generally triangular in cross-section and tapering from the proximal end to the distal end, the distal end defining an insertion portion, the elongate body further having a bottom surface, an inside surface and an outside surface opposite the inside surface, wherein the bottom surface and the inside surface define a first edge where they meet, the outside surface and the inside surface define a second edge where they meet, and the outside surface and the bottom surface define a third edge where they meet, the elongate body being curved in a horizontal plane along its entire length towards the inside surface such that the inside surface is adapted to hold the matrix band in conformance to the anatomical tooth surface, and the proximal end defining a terminal head portion adapted to being grasped by a suitable tool or implement to facilitate placement and removal of the dental wedge between said teeth, and wherein the inside surface is concave transversely to the elongate body entirely from the first edge to the second edge, and the outside surface is convex transversely to the elongated body entirely from the second edge to the third edge.
