Abstract: A connector for orthodontic headgear includes a casing for a helical compression spring one end of which engages the head of a rod extending through the spring. The other end of the spring engages a sleeve supported in an aperture in the end of the casing. Such casing aperture has a straight chordal portion and the sleeve has axially spaced circumferential flanges with chordally truncated portions for enabling the sleeve to be moved axially relative to the casing flange when in one rotative position for adjusting the spring force and rotatively adjustable relative to the casing flange to hold the sleeve in a selected adjusted position. The connection is disconnectible by providing a metal clip securable to a headcap having legs engageable in grooves in the casing.

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.
