Method and system for enhanced orthodontic trearment plenning
First Claim
1. A method for quickly arriving at a virtual pre-set-up of the orthodontic treatment plan for a patient, based up on the user specified parameters, using virtual 3D dentition model of a patient, and a global reference system, comprising the steps of:
- a. activating the controlled tipping filter;
b. creating the occlusal surface of the upper and lower jaw by using the indicated reference teeth of the malocclusion or of any other reference stage;
c. creating the arch form spline for the reference jaw by using the indicated reference teeth under consideration of the offset value of the AP-position of the front as well as of the desired symmetrical characteristic;
d. determining the relative transversal position of the incisal contact points by using the standardized offset value (midline);
e. aligning on arch form spline. (horizontal correction of the position of the teeth) usage of eventually standardized fixed interproximal distances;
f. aligning on the Occlusual Surface under consideration of potential offset values for the vertical position of the teeth;
g. aligning again on arch form spline in order to correct interferences with the vertical alignment;
h. making the mesiodistal shift of the lateral segments in order to keep the sagittal position of the first molars e.g. under consideration of a possibly standardized offset value; and
i. adjusting of possibly created interproximal gaps or intersections in the front by the equal distribution of all created gaps or intersections on the individual interproximal space between the teeth on the left and the right half of the jaw.

Abstract
A method and system are disclosed for quickly arriving at a pre-set-up for the orthodontic treatment of a patient based up on the user specified parameters; and thereafter enabling the user in interactively arriving at a final, desired treatment set-up for the patient. Several sub-operations are disclosed for arriving at the orthodontic pre-set-up. These sub-operations can be arranged in a specific sequence for realizing the orthodontic treatment pre-set-up for a patient. According to another aspect of the invention, a global reference system is disclosed that enables consistent treatment planning. The global reference system prevents unintended tooth displacements caused as side effects to the desired tooth displacements.
