Abstract: The present invention provides a method of moving at least one tooth within a plurality of teeth. Pursuant to the method, one must determine the mass of the tooth and determine the initial position of the tooth.

After the expiration of the given period of time, the new position of the tooth is determined, and the Newtonian physics equations are calibrated by adjusting the equations to compensate difference between the actual position of the tooth as compared to the predicted position of the tooth under the previously calculated force.
