Abstract: A dental appliance occlusal element includes a lower surface comprising one or more features configured to interface with a pick-and-place robot to cause the dental appliance occlusal element to be inserted into a hollow feature of a dental appliance. The dental appliance occlusal element further includes an upper surface configured to be disposed adjacent a distal inner surface of the hollow feature. The dental appliance occlusal element further includes one or more side surfaces configured to be disposed against one or more side inner surfaces of the hollow feature.

Abstract: Implementations describe systems and methods for manufacturing and performing quality assessment of dental appliances. In one embodiment, a method of manufacturing a dental appliance comprises receiving, at a holder, a feature of the dental appliance, the feature comprising a first surface having a first shape, wherein the holder holds the feature of the dental appliance at a reference position. The method further includes automatically placing an object against the feature at the reference position using a robot arm, wherein the object comprises a second surface having a second shape that mates with the first shape. The method further includes applying pressure to press the object against the feature of the dental appliance and bonding the object to the feature of the dental appliance while applying the pressure.
