摘要：An orthodontic appliance is provided which applies a vibrational force to the tooth to be moved, rather than a continuous force as is the case with the usual prior art devices. The invention is predicated on the concept that when vibrational forces are applied to the tooth, there is little or no hyalinization and consequently more cellular activity giving rise to more oesteoclasts for bone resorption and more oesteoblasts for bone apposition. Moreover, the vibrational 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. In the assembly of the present invention, the vibrational effect is produced by a radio and speaker mounted on an orthodontic appliance, or directly on the tooth, in response to radio waves transmitted by an adjacent radio transmitter.
