Abstract: Multiple techniques for detecting defects in customized dental appliances are disclosed. In one technique, processing logic obtains one or more images of a customized dental appliance, obtains a digital model associated with the customized dental appliance, and performs segmentation on the one or more images to identify an area of the one or more images that comprises a representation of the customized dental appliance. Processing logic then registers the one or more images to the digital model, compares the area of the one or more images of the customized dental appliance with the digital model of the customized dental appliance, determines a difference between the area of the one or more images that comprises the representation of the customized dental appliance and the digital model of the customized dental appliance at a region, and determines whether the difference satisfies a defect criterion.

Abstract: A virtual filler is inserted in a virtual model of a dental site between a first tooth and a second tooth in the virtual model. One or more of the first tooth or the second tooth represent a natural tooth of a patient. Points of the first tooth, the second tooth 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 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: 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.
