Abstract
An orthodontic appliance comprising an upper splint defining a set of tooth sockets for secure but removable retention to the upper set of teeth, a lower splint defining a set of tooth sockets for secure but removable retention to the lower set of teeth, and a pair of elastic linkages which connect the upper and lower splints so as to force the maxilla forward. A traction bow with two ends adapted for releasable connection to the lower splint is provided with a sub bar fixed to its frontal center, and a hook is provided on each side of the upper splint. An elastic linkage is removably connected between each of the hooks and a clasp on an end of the sub bar. The sub bar is substantially shorter in length from end to end than the main bowed bar of the traction bow.
