Abstract: An example removable dental appliance includes an appliance body configured to at least partially surround a plurality of teeth of a dental arch of a patient. The appliance body includes a shell shaped to engage a tooth in an initial position and a gingival ridge extending from a mesial interproximal region along a gingival edge of the shell to a distal interproximal region. The gingival ridge is configured to engage a lingual or labial surface of the tooth below a height of contour of the tooth to enable the appliance body to apply a force vector at a contact point on the tooth to cause movement of the tooth toward a desired position of the tooth when the removable dental appliance is worn by the patient.

Abstract: Techniques are described for automating the design of dental restoration appliances using neural networks. An example computing device receives transform information associated with a current dental anatomy of a dental restoration patient, provides the transform information associated with the current dental anatomy of the dental restoration patient as input to a neural network trained with transform information indicating placement of a dental appliance component with respect to one or more teeth of corresponding dental anatomies, the dental appliance being used for dental restoration treatment for the one or more teeth, and executes the neural network using the input to produce placement information for the dental appliance component with respect to the current dental anatomy of the dental restoration patient.

Abstract: The present disclosure provides a method of making a ceramic article. The method includes (a) obtaining a photopolymerizable slurry or sol including a plurality of ceramic particles distributed in the photopolymerizable slurry or sol and (b) selectively polymerizing the photopolymerizable slurry or sol using actinic radiation and continuous movement of a build substrate through the photopolymerizable slurry or sol to form a gelled article. The method also includes (c) extracting solvent from the gelled article to form an aerogel article or a xerogel article; (d) heat treating the aerogel article or the xerogel article to form a porous ceramic article; and (e) sintering the porous ceramic article to form a sintered ceramic article. The sintered ceramic article exhibits a particular density. Further, additive manufactured ceramic articles are provided that exhibit a particular density, opacity, or both. Preferably, all cross-sectional portions of an interior of the ceramic article having selected dimensions are free of a frequency analysis signal maxima larger than a background signal.

Abstract: A tool for forming a dental restoration includes a mold body configured to provide a customized fit with at least one tooth of a patient. In some examples, the mold body defines an aperture configured to align with a portion of a surface of a tooth. The aperture is sufficiently large to allow placement and flow of restorative material over the desired portion of the surface of the tooth to be restored. The mold body is configured to combine with the at least one tooth of the patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored.

Abstract: A tool for forming a dental restoration includes a mold body configured to combine with a tooth of a patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth. In some examples, the portion of desired tooth structure defines an interproximal surface of the tooth. The mold body may include, in some examples, a base member configured to provide a customized fit with at least one tooth of the patient to attach the mold body to the at least one tooth, and an interproximal member extending from the base member and configured to be disposed between adjacent teeth of the patient when the base member is fit over the at least one tooth. The interproximal member defines a surface of the mold cavity.

Abstract: In some examples, a tool for forming a dental restoration comprises a preformed mold body configured to provide a patient-specific, customized fit with at least one tooth to be restored of a patient. The mold body is configured to align with a portion of a surface of the at least one tooth, and is configured to combine with the at least one tooth to define a mold cavity encompassing at least a portion of desired tooth structure of the at least one tooth to be restored of the patient. The portion of desired tooth structure defines a transition from a supragingival surface of the at least one tooth to a subgingival surface of the at least one tooth.

Abstract: Various embodiments of an orthodontic appliance and method of forming such appliance are disclosed. In one or more embodiments, the orthodontic appliance can include an arch member including an arch member body and an arch member coupling connected to the body. The orthodontic appliance can also include an anchor including an anchor coupling and a base adapted to connect the anchor to a surface of a tooth. The arch member coupling can be releasably connectable to the anchor coupling, and the anchor can be adapted for displacement relative to the arch member body when the anchor is connected to the surface of the tooth and the arch member coupling is connected to the anchor coupling.
