Publication number: 20250221796Abstract: Methods for automatically removing collisions between digital mesh objects and moving digital mesh objects between spatial arrangements. The collisions are removed from a set of digital mesh objects using a perturbation method or a mesh deformation method. After removing the collisions, the digital mesh objects are output in a state without collisions between them. The digital mesh objects can be moved between initial and final states based upon motion constraints of the mesh objects and interpolated states of them between the initial and final states. Based upon the constraints and interpolated states, a number of states for movement of the set of digital mesh objects is determined either collectively for the set or individually for each mesh object. The states can be used as digital setups for dental or orthodontic treatment planning.Type: ApplicationFiled: March 26, 2025Publication date: July 10, 2025Inventors: Alexandra R. Cunliffe, Benjamin D. Zimmer, Guruprasad Somasundaram, Deepti Pachauri, Jonathan D. Gandrud, Arash Sangari, Shawna L. Thomas, Nancy M. Amato
