Zusammenfassung:	A system comprises a memory comprising instructions for detecting one or more defects in a customized dental appliance manufactured via direct fabrication, and a processing device. Execution of the instructions causes the processing device to determine an area of the one or more images of the customized dental appliance to be compared with a digital model of the customized dental appliance, compare the area of one or more images of the customized dental appliance with the digital model of the customized dental appliance, determine a difference between a representation of the customized dental appliance in the area of the one or more images and the digital model of the customized dental appliance at a region of the customized dental appliance, and responsive to determining that the difference satisfies a defect criterion, determine that the customized dental appliance has a manufacturing defect at the region associated with the difference.
