Abstract
A system includes an orientation determination system comprising a camera where the camera is configured to capture an image of an orientation feature of a physical dental model of a dental arch of a customer with material thermoformed thereon. The orientation determination system is configured to identify an offset of the physical dental model with respect to a fixture plate during positioning or before or after the physical dental model is positioned on the fixture plate by determining an actual orientation of the physical dental model based on the orientation feature. The system also includes a laser trimming system configured to cut the material along a trim line based on the identified offset while the fixture plate is moved about at least two axes to produce a dental aligner specific to the customer and being configured to reposition one or more teeth of the customer.
