Abstract: A system for repositioning teeth comprises a plurality of individual appliances. The appliances are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from a initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The system of appliances is usually configured at the outset of treatment so that the patient may progress through treatment without the need to have the treating professional perform each successive step in the procedure.

Abstract: Systems and methods are disclosed to prepare a malocclusion treatment plan by selecting a tooth treatment pattern from a library of predetermined tooth treatment patterns; and generating the malocclusion treatment plan implementing the selected tooth treatment pattern.

Abstract: The present invention provides methods and systems of repositioning teeth for use in orthodontic treatment, with particular applicability to removable elastic repositioning appliances. Such appliances may be challenged by traditional tooth movements which intrude the crown of the tooth or present tooth positions which reduce available points of purchase. These challenges may be overcome with a series of tooth movements in which a tooth is translated in a “root-first” position. The movements may take advantage of the inherent characteristics of elastic repositioning appliances in translating a tooth from a first position to a desired position along a gingival plane.
