Defect detection of molds for orthodontic aligners

A system for analyzing a quality of a fabricated mold for an orthodontic aligner, the system comprising:

• a processor and memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to:
• receive a digital representation of the fabricated mold for the orthodontic aligner, the digital representation having been generated based on imaging of the fabricated mold;
• analyze the digital representation of the fabricated mold to identify a quality-related property of the fabricated mold;
• determine, based on the quality-related property, that the fabricated mold comprises a defect;
• and
• classify the fabricated mold as having the defect.

A quality control system comprising:

• an image capture device configured to generate a digital representation of a fabricated mold for an orthodontic aligner;
• a light source configured to illuminate the fabricated mold in a manner that enhances an image quality of the digital representation of the fabricated mold;
• and
• a computing device to:
• analyze a quality-related property of the digital representation of the fabricated mold;
• determine, based on the quality-related property, that the fabricated mold comprises a defect;
• and
• classify the fabricated mold as defective based on determining that the fabricated mold comprises the defect.

A non-transitory computer readable medium comprising instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving, by a processor, a digital representation of a fabricated mold for an orthodontic aligner, the digital representation having been generated based on imaging of the fabricated mold;
• analyzing, by the processor, the digital representation of the fabricated mold to identify a quality-related property of the fabricated mold;
• determining, based on the quality-related property, that the fabricated mold comprises a defect;
• and
• classifying, by the processor, the fabricated mold as defective based on determining that the fabricated mold comprises the defect.
