Abstract: 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.

Abstract: A system includes a memory device and a processing device operatively coupled to the memory device. The processing device determines two or more adjacent teeth in a virtual model, determines a characteristic of the teeth indicative of a spatial relationship between the teeth, determines that the characteristic satisfies a criterion for a virtual filler, and determines a geometry of the virtual filler based on the spatial relationship between the teeth.

Abstract: Two or more adjacent teeth in a virtual model are determined. The two or more adjacent teeth include a first tooth adjacent to a second tooth in the virtual model. The virtual filler is inserted in the virtual model between the first tooth and the second tooth. Points in the virtual model are selected. The points and the virtual filler are transformed into a voxel volume. A geometry of an updated virtual filler is determined by transforming a surface of the voxel volume into a polygonal mesh.

Abstract: A processing device determines two or more adjacent teeth in a virtual model, the two or more adjacent teeth include a first tooth adjacent to a second tooth in the virtual model. The processing device inserts a first virtual filler in the virtual model between the first tooth and the second tooth. The processing device selects points in the virtual model. A processing device transforms the plurality of points into a voxel volume comprising a plurality of voxels. A processing device performs a smoothing operation on the voxel volume. A processing device subsequent to performing the smoothing operation on the voxel volume, determines a geometry of an updated virtual filler by transforming a surface of the smoothed voxel volume into a polygonal mesh.

Abstract: A method includes manufacturing an orthodontic aligner and assessing a quality of the orthodontic aligner. Assessing the quality of the orthodontic aligner comprises receiving a digital representation of the orthodontic aligner, and analyzing the digital representation of the orthodontic aligner to identify a quality-related property of the orthodontic aligner. The analyzing comprises comparing the digital representation of the orthodontic aligner with data based on a digital model associated with the orthodontic aligner and calculating one or more difference between a feature determined from the data and a feature of the digital representation of the orthodontic aligner. Assessing the quality of the orthodontic aligner further includes determining, based on the quality-related property, that the orthodontic aligner comprises a possible manufacturing flaw, and classifying the orthodontic aligner as requiring further inspection by a technician based on determining that the orthodontic aligner comprises the possible manufacturing flaw.

Abstract: A method of manufacturing and analyzing a quality of an orthodontic aligner is described. An orthodontic aligner is manufactured by printing a mold associated with a dental arch of a patient based on a digital model of the mold, forming an orthodontic aligner over the mold, and trimming the orthodontic aligner. A quality of the orthodontic aligner is then assessed by imaging the orthodontic aligner to generate a first digital representation of the orthodontic aligner, comparing the first digital representation of the orthodontic aligner to a digital file associated with the orthodontic aligner, determining whether a cutline variation is detected between the orthodontic aligner and the digital file, and determining whether there is a manufacturing defect of the orthodontic aligner based on whether the cutline variation exceeds a cutline variation threshold.
