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.

-2. (canceled)
A method of evaluating an orthodontic treatment plan, the method comprising:
- generating an orthodontic treatment plan comprising a first stage and a second stage;
- generating a 3D model of the patient's teeth at the first stage;
- generating a 3D model of an orthodontic appliance at the second stage;
- receiving input comprising a stiffness matrix of the patient's teeth and a stiffness matrix of the orthodontic appliance;
- modeling mechanical interactions of the orthodontic appliance at the second stage with the patient's teeth at the first stage based at least in part on the stiffness matrix of the patient's teeth applied to the 3D model of the patient's teeth and the stiffness matrix of the orthodontic appliance applied to the 3D model of the orthodontic appliance;
- and
- modifying the orthodontic treatment plan based on the modeled mechanical interactions.
A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more computer processors, cause the one or more computer processors to perform operations comprising:
- generating an orthodontic treatment plan comprising a first stage and a second stage;
- generating a 3D model of the patient's teeth at the first stage;
- generating a 3D model of an orthodontic appliance at the second stage;
- receiving input comprising a stiffness matrix of the patient's teeth and a stiffness matrix of the orthodontic appliance;
- modeling mechanical interactions of the orthodontic appliance at the second stage with the patient's teeth at the first stage based at least in part on the stiffness matrix of the patient's teeth applied to the 3D model of the patient's teeth and the stiffness matrix of the orthodontic appliance applied to the 3D model of the orthodontic appliance;
- and
- modifying the orthodontic treatment plan based on the modeled mechanical interactions.
