The Jones Jig is a simple, but effective appliance for distalizing upper molars. It may be used for bilateral or unilateral corrections. The mainframe is inserted into the buccal tube and ligated. The superelastic coil spring is slid onto the mainframe wire and secured by the sliding eyelet tube. Force is obtained by compressing the spring and ligating the eyelet to the bicuspid bracket. Anchorage support is provided with a Nance appliance.
