Abstract: Orthodontic articles and polymerizable resin compositions are described. The orthodontic article comprises a cured composition comprising the reaction product of free-radically polymerizable resin comprising 30 to 70 wt. %, inclusive, of at least one urethane component, and 25 to 70 wt. %, inclusive, of reactive diluent(s) comprising at least one monofunctional (meth)acrylate monomer. The polymerizable resin comprises no greater than 35 wt. % of reactive diluent(s) having a high affinity for water. Reactive diluent(s) such as monofunctional (meth)acrylate monomers having a high affinity for water have low log P values.

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: An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a one-piece mold body providing for a customized fit with at least one tooth of the patient, the one-piece mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, and a distal proximal portion forming a distal proximal surface corresponding with a distal proximal 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. The occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of 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: Machine learning, or geometric deep learning, applied to various dental processes and 5 solutions. In particular, generative adversarial networks apply machine learning to smile design—finished smile, appliance rendering, scan cleanup, restoration appliance design, crown and bridges design, and virtual debonding. Vertex and edge classification apply machine learning to gum versus teeth detection, teeth type segmentation, and brackets and other orthodontic hardware. Regression applies machine learning to coordinate systems, diagnostics, case complexity, and 0 prediction of treatment duration. Automatic encoders and clustering apply machine learning to grouping of doctors, or technicians, and preferences.

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: The present disclosure provides a multiphoton imaging method. The method includes a) immersing a semi-submersible microscope objective in a liquid medium that is at least one of scattering or absorbing; b) directing laser light through the semi-submersible microscope objective and into the liquid medium in an image-wise manner under conditions such that multiphoton absorption by the multiphoton absorber occurs, and at least partial polymerization of the polymerizable compound occurs resulting in an article; and c) removing uncured polymerizable compound to clean the article. The liquid medium includes a polymerizable compound, a secondary component, and a multiphoton absorber. An article is also provided. The article includes a material defining one or more tortuous or arcuate channels, one or more internal architectural voids, one or more undercuts, one or more perforations, or combinations thereof, at least one of which exhibits a surface roughness of 1.0 micrometer Ra or less.

Abstract: The present disclosure provides a method of making an orthodontic article. The method includes (a) providing a photopolymerizable composition; (b) selectively curing the photopolymerizable composition using actinic radiation to form an article in the shape of an orthodontic article including a number of layers of at least one photopolymerized polymer; and (c) moving the article and thereby generating a mass inertial force in the uncured photopolymerizable composition. The article has a first surface, and no more than 75% of the first surface has a slope magnitude greater than 2.5 degrees. Orthodontic articles are also provided, including an orthodontic article that is prepared according to the method. Orthodontic articles having low extractable component content are further provided. The mass inertial force tends to form a coating layer of uncured photopolymerizable composition on the article, and curing the coating layer can form a surface having low slope magnitude. The low slope magnitude may be correlated to a low haze of the surface of the article.
