Patent ID: 7744370

Claim:
A dental device for insertion of a crown, consisting essentially of: a substantially planar elongated base layer having a marking portion and a resistance testing portion, separated by a frangible joint, the base layer having opposed first and second surfaces, wherein said marking portion and said resistance testing portion each have a longitudinally opposed end located opposite the frangible joint and a common longitudinal axis traversing the ends and the frangible joint, said marking portion and said resistance testing portion being substantially symmetrically configured about the frangible joint located at the approximate midpoint of the base layer; and a first marking layer formed from a transferable medium coated on the first surface of the marking portion of the base layer, the first marking layer being adapted for positioning against an upper surface of an occlusally reduced tooth to mark raised regions of the upper surface, the resistance testing portion being adapted for positioning between the occlusally reduced tooth and a vertically opposed tooth following marking of the raised regions, the resistance testing portion being adapted for frictionally engaging the occlusally reduced tooth and the vertically opposed tooth in order to measure the degree of occlusal reduction of the occlusally reduced tooth.
