Abstract
A front body or plate for disposition in front of an arch wire is connected to a fork for disposition behind the arch wire by a crosstie forming a mounting that can be slid lengthwise of the arch wire to enable the fork to embrace the body of a tooth bracket behind the arch wire. A saddle projecting from the front body opposite the fork projects rearward to form a socket engageable with the arch wire by movement transversely of the arch wire. The prong of the fork nearer the rearward projection of the saddle may be shorter than the prong of the fork farther from the rearward projection to facilitate installation of the mounting.
