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.
