Abstract: A method of automated defect detection of a dental appliance comprises receiving a plurality of images of the dental appliance, and processing the plurality of images by a processing device to determine one or more defect estimations. The method comprises processing one or more sets of defect estimations to determine one or more defect classifications, wherein each set of the one or more sets comprises the one or more defect estimations associated with a subset of the plurality of images. The method comprises determining whether the dental appliance has a defect based on the one or more defect classifications associated with the one or more sets of defect estimations.
