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.
