摘要：
A dental tool having a processing section at one end which includes a longitudinally extending lateral face and a transversely extending front face having an abrasive working face located at a distance from the lateral face so as to permit forming a precise marginal edge around a tooth to permit precise positioning of a crown while avoiding deleterious working of the tooth region nearest the stump on which the crown is to be mounted.
