This abstract first appeared for US patent application 18890537 titled 'ORTHODONTIC APPLIANCE RETENTION-ACTIVATION SYSTEMS AND METHODS
Original Abstract Submitted
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.
