ABSTRACT:
A pistol grip has twin abutments projecting in parallel relationship and spaced apart to straddle an orthodontic bracket attached to a tooth and to engage the tooth at opposite sides of the bracket. A swing handle pivoted to the pistol grip carries a pull wire extending between the abutments such pull wire has a loop for hooking a wing of the orthodontic bracket. The handle can be pulled toward the pistol grip to draw the pull wire toward the pistol grip for pressing the abutments against the tooth and simultaneously pulling the bracket off the tooth. During such pulling, constriction of the arch wire slot in the bracket is prevented by fitting in such slot a spacer hook of a tenaculum.
