Abstract: Methods and systems for generating multiple dental treatment plans. A digital model representing an initial tooth position of the patient's teeth and a comprehensive final tooth position for the patient's teeth may be accessed. The comprehensive final tooth position may represent an ideal tooth position. Numerical functions representing treatment targets may be determined based on a set of treatment preferences and treatment details. A single numerical merit function may be generated by calculating a weighted sum of the numerical functions. A solution vector may be determined by minimizing the single numerical merit function subject to numerical limits, where the numerical limits are based on the set of treatment preferences and treatment details and the comprehensive final tooth position. The solution vector may be mapped to the treatment plan, wherein the treatment plan includes a final tooth position that is different from the comprehensive final tooth position.

Abstract: Orthodontic and/or dental treatment planning methods and apparatuses. In particular, described herein are methods of generating a plurality of potential treatment plan variations for the concurrent and interactive review of the treatment plan variations. Treatment settings may be determined based on initial tooth positions and may be arranged in a hierarchy of treatment settings. Each of the plurality of treatment plans may be generated based on a set of treatment settings from the hierarchy of treatment settings. Also described herein are orthodontic and/or dental treatment planning methods and apparatuses that present the plurality of treatment plans to the user to allow a user to select a treatment plan from a plurality of different treatment plans.
