ABSTRACT:
A hand held abrasive dental instrument for use in cutting the proximal aspect of a tooth's surface to create an interproximal space between abutting tooth surfaces. The instrument features a thin circular disc shaped abrasive cutting member provided with a coating of abrasive material over one of the circular surfaces of the disc which is rotatably mounted between abutting handle portions. The handle portions serve to provide means for convenient grasping of the instrument by the user in a manner which permits facile manipulation of the cutting disc between abutting teeth. The handle portions are constructed to automatically lock the disc against rotation when grasped in the normal operational mode so that effective cutting can be accomplished. However, upon releasing the grasping pressure, the disc may be rotated to position an unused portion of the abrasive coating for operative use.
