1. An orthodontic appliance comprising:
- a bow element comprising an external oral arch bow and an internal oral arch bow adapted to be engaged with a band on a tooth to apply a force to the tooth to move the tooth in a predetermined direction in the mouth of a patient; and
an electric pulsating motor coupled to said bow element to exert a reciprocating force on said bow element to cause said bow element to exert a pulsating force on the tooth.

Abstract
An orthodontic appliance is provided which applies a pulsating force to the tooth to be moved, rather than a continuous force as in the case with the prior art devices. The invention is predicated on the concept that when pulsating forces are applied to the tooth, there is little or no hyalinization and consequently more cellular activity, giving rise to more oesteoclastic activity for bone resorption and more oesteoblastic activity for bone opposition. Moreover, the pulsational effect of the tooth on the adjacent periodontal membrane and bone tends to loosen their fibrous structure, and helps the tooth to find a path of least resistance through the bone.
