Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a mold body providing for a customized fit with at least one tooth of the patient. The mold body includes a facial portion forming a facial surface corresponding with a facial surface of the tooth, and a separate lingual portion forming a lingual surface corresponding with a lingual surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth.

Abstract: A 3D imaging apparatus with enhanced depth of field to obtain electronic images of an object for use in generating a 3D digital model of the object. The apparatus includes a housing having mirrors positioned to receive an image from an object external to the housing and provide the image to an image sensor. The optical path between the object and the image sensor includes an aperture element having apertures for providing the image along multiple optical channels with a lens positioned within each of the optical channels. The depth of field of the apparatus includes the housing, allowing placement of the housing directly on the object when obtaining images of it.

Abstract: Methods for estimating and predicting tooth wear based upon a single 3D digital model of teeth. The 3D digital model is segmented to identify individual teeth within the model. A digital model of a tooth is selected from the segmented model, and its original shape is predicted. The digital model is compared with the predicted original shape to estimate wear areas. A mapping function based upon values relating to tooth wear can also be applied to the selected digital model to predict wear of the tooth.

Abstract: Methods for aligning a digital 3D model of teeth represented by a 3D mesh to a desired orientation within a 3D coordinate system. The method includes receiving the 3D mesh in random alignment and changing an orientation of the 3D mesh to align the digital 3D model of teeth with a desired axis in the 3D coordinate system. The methods can also detect a gum line in the digital 3D model to remove the gingiva from the model.

Abstract: Three-dimensional test objects provide for assessment of a 3D scanner over a range of scales, frequencies, and/or depths. The test objects may include a substrate having a substantially planar top surface and a plurality of surface features. In some examples, the surface features include a plurality of wedges projecting above the plane of the top surface and extending radially outward from an origin to form a three dimensional star pattern. The shape of the surface features may be periodic or non-periodic. In other examples, the depth of the surface features is decoupled from their lateral frequency.
