Abstract: An orthodontic tool for placing and measuring bends or twists in orthodontic arch wires, or the like, in order to place potential torquing forces in the wire, comprises first and second engaging means for engaging an elongated wire on respective opposite surfaces of the wire, one of the engaging means carrying an indicator member with a scale thereon and the other of the engaging means carrying a pointer. When the two engaging means are placed together and twisted around the arch wire, the pointer will indicate the exact degree of twist being placed in the wire on the indicating scale. The engaging means may comprise pliers, keyed members, or the like. Preferably, the scale is interposed between the engaging means to provide a bending space between the engaging means to prevent weakening of the wire when it is twisted. Also disclosed is a tool for bending orthodontic arch wires to provide second order bends.

Abstract: An orthodontic threading tool comprises a handle portion having at one or both ends thereof a shank portion extending from the handle portion, a loop portion extending from the shank portion and a threading portion extending from the loop portion. The loop portion extends from the shank in the direction away from the longitudinal axis of the shank. The threading portion extends away from the loop portion such that at least part of the threading portion is located on the opposite side of the longitudinal axis of the shank from that of the loop portion. The threading portion has a curved or bent area defining a camming or bearing surface along which said threading portion is engageable with an arch wire or the like so as to permit a revolving action of the free end of the threading portion about the arch wire or the like. A hook member is provided at the free end of the threading portion for engaging an orthodontic thread, or the like.
