    摘要： A method for training a neural network intended to analyze a dental situation of an updated patient. A historical learning database is created that relates to a dental body and to a spatial attribute associated with the dental body. The historical learning database includes more than 1,000 historical records, with each historical record relating to a respective historical patient. Each record including a set of historical images all depicting the dental body in the historical patient, called “historical dental body” and an item of spatial information including, for the historical patient, a set of values for the spatial attribute, called “historical spatial information.” The neural network is trained, by providing it with the sets of historical images as input and with the historical spatial information as output, with the spatial attribute defining an ordered sequence of variables in a three-dimensional reference frame.

    摘要： An orthodontic aligner includes a first plastic segment having a first shape that fits over a first portion of a dental arch of a patient, a second plastic segment having a second shape that fits over a second portion of the dental arch of the patient, and a connector that joins the first plastic segment to the second plastic segment. The connector is configured to be disposed along a lingual side of one or more additional teeth of the patient without exerting a clinically significant force on the one or more additional teeth. The connector spans a gap between the first plastic segment and the second plastic segment, the gap corresponding to the one or more additional teeth that are not to receive the clinically significant force. The connector includes a flexible material that will perform at least one of flex, move or change shape responsive to applied forces.

    摘要： A method for performing enamel replacement on a tooth in the mouth of a person, the method including: beginning an arch reformulation therapy (ART) process, selecting a tooth for an enamel replacement process to be performed on, identifying a surface of the tooth to have a dental composite material adhered to as part of the enamel replacement process, discluding multiple teeth during the ART process including the selected tooth, preparing the identified surface of the selected tooth for adherence of a dental composite material, the preparation including application of a preparation material to the surface of the tooth, and applying the dental composite material to the prepared surface.

    摘要： A dental appliance made of an olefin polymer is directly formed via rapid prototyping without the use of an intermediary physical mold. A polymer precursor solution includes one or more olefin-containing monomers and/or oligomers, an olefin polymerization catalyst, and a UV absorbing agent to limit penetration of the UV light through the polymer precursor solution. One or more reactions of the polymer precursor solution are modulated in response to UV light, and the polymer precursor solution may further include an inhibitor (quenching agent) configured to modulate those reactions. The polymer precursor solution can be deposited using UV-cured stereolithographic or 3D printing methods to form appliances exhibiting improved elongation at break characteristics and suitable stress resistance.

    摘要： The present disclosure provides computing device implemented methods, computing device readable medium, and molds for filling undercut areas of teeth relative to an axis of placement. Filling undercut areas of teeth relative to an axis of placement can include calculating an undercut area of a tooth relative to an axis of placement of part of a dental appliance over a number of teeth and a height of contour that is defined based on the axis of placement. Filling undercut areas of teeth relative to an axis of placement can also include filling in a part of the undercut area of the tooth with a virtual filler wherein the undercut is filled to within a threshold distance from the tooth that is defined relative to the axis of placement and the height of contour.

    摘要： The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, and providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.
