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.

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: 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: Techniques are described for automating the design and manufacture a dental restoration appliance for restoring the dental anatomy of a patient. For example, a system processes a digital three-dimensional (3D) model of a future (desired) dental anatomy of a patient, the future dental anatomy representing an intended shape of at least one tooth of the patient. The system includes a landmark identifier configured to automatically compute, based on the digital 3D model of the future dental anatomy of the patient, one or more landmarks of the future dental anatomy of the patient. The system also includes a custom feature generator configured to automatically generate, based on the one or more landmarks, one or more custom appliance features for a dental appliance for restoring the at least one tooth of the patient. The system further includes a memory device configured to store a digital model of the dental appliance.

Abstract: A removable dental appliance may include an appliance body configured to at least partially surround a plurality of teeth of a dental arch of a patient. The appliance body may include a unitary material defining a shell shaped to receive at least one tooth of the patient and a spring member integrally formed with the shell. The spring member may be configured to receive an attachment. The attachment may be configured to affix to the at least one tooth. The spring member may be configured to apply a spring force to the attachment to cause at least one of a rotation, a translation, a tipping, a torqueing, an extrusion, or an intrusion of the at least one tooth toward a desired position of the tooth when the removable dental appliance is worn by the patient.
