A method includes identifying one or more images of a mold of a dental arch, identifying a digital model corresponding to the mold of the dental arch, providing the one or more images and the digital model as input into a trained machine learning model, receiving, from the trained machine learning model, output, and determining, based on the output, whether the mold matches the digital model.

Dynamic thermoforming of dental appliances

A method includes identifying first geometry of a first mold associated with a first dental arch and a second geometry of a second mold associated with a second dental arch. The method further includes determining, based on the first geometry and the second geometry that the first mold and the second mold are to be used for simultaneous forming of a first dental appliance and a second dental appliance on a plate in a dental appliance manufacturing system. The method further includes causing, based on the first geometry and the second geometry, one or more portions of the dental appliance manufacturing system to be configured to form the first dental appliance and the second dental appliance.

A system includes a heating section configured to heat a sheet of plastic to generate a heated sheet of plastic. The system includes a plate configured to secure a mold associated with a dental arch of a patient. The plate includes a locking mechanism. The mold includes feature configured to interface with the locking mechanism. The system further includes a thermoforming chamber configured to thermoform the heated sheet of plastic to the mold that is secured to the plate via an interface of the locking mechanism with the feature to generate a thermoformed sheet of plastic. The locking mechanism is configured to extend through the mold and overlap an upper surface of the mold to lock the mold in a z-direction that is orthogonal to a plane defined by the plate. The system further includes a cutting tool configured to trim an aligner from the thermoformed sheet of plastic.
