Abstract: A system and method for determining a center of resistance of a tooth may include receiving a 3D digital representation of an initial arrangement and a final arrangement of a patient's teeth and determining a 3D treatment plan. The 3D treatment plan may include a plurality of 3D stages for rearranging the teeth from the initial arrangement toward the final arrangement. The method may also include determining, in accordance with the 3D treatment plan, an intended movement of the teeth for each of the stages and deriving, using a 3D resistance model, an applied force system for achieving the intended movement of the teeth for each of the stages. The method may also include deriving 3D geometries of oral appliances for the stages in response to the applied force system. Various other systems and methods are also disclosed.

Abstract: Systems and methods of simulating, modeling, and validating orthodontic treatment are disclosed. The method may include designing an orthodontic treatment system or force system, generative a displacement field between a first position of a patient's teeth and a second position, modeling the three-dimensional force-displacement model generated by the treatment system or force system, and validating the treatment system or force system. The methods disclosed herein may be iterated to optimize the orthodontic force system or treatment system.

Abstract: A system for generating aligner shapes may include one or more processors and memory comprising instructions that when executed by the one or more processors, causes the system to carry out a method. The method may include determining a desired force system for moving a tooth, generating a population of sets of degrees of freedom and contact surfaces, determining a force system for each of the sets in the population evaluating a cost function of each of the force systems compared to the desired force system, updating the population of sets of degrees of freedom and contact surfaces based on the cost function of each of the force systems, and repeating determining a force system, evaluating a cost function and updating the population until the determined force system for one of the sets matches the desired force system, to generate a final set of degrees of freedom and contact surfaces.

Abstract: Methods and apparatuses (including software) for optimizing dental treatment plans, including for optimizing the treatment plans using dental aligners. These methods and apparatuses may optimize a treatment plan by estimating a difference between a target set of tooth position and a predicted set of tooth positions using the treatment plan using a prediction network trained to use multiple translational and rotational directions for individual teeth as well as reaction forces on the individual teeth based on adjacent teeth.
