Systems, methods, and computer-readable media for identifying and facilitating review of outlier treatment plans. A method includes receiving an initial three-dimensional (3D) model of an initial arrangement of a patient’s teeth and generating a first final 3D model of a first final arrangement of the patient’s teeth based on the initial 3D model of the initial arrangement of the patient’s teeth. The method further includes comparing the first final arrangement of the patient’s teeth with a set of a plurality of final arrangements of teeth from previous treatment plans of past patients and determining whether the first final arrangement of the patient’s teeth satisfies one or more outlier criteria based on the comparing. Responsive to determining that the first final arrangement of the patient’s teeth satisfies the one or more outlier criteria, an orthodontic treatment plan comprising the first final 3D model of the first final arrangement of the patient’s teeth is classified as a clinical risk.

A unique CAD subtract body intended to create a design of a mating surface for a veneering overlay and a dental implant framework wherein the unique CAD subtract body is derived from a diagnostic wax-up surface model. The diagnostic wax-up surface model is created from at least one of scanning a diagnostic wax up or denture tooth set up, CAD models in a virtual set up, an intraoral scan of a diagnostic wax up or denture tooth set up taken in a patient's mouth, a CT scan or series of CT scans of a patient's mouth, a CT scan or series of CT scans with the use of a radiographic stent in a patient's mouth, and wherein the unique CAD subtract body can be used to create the tool path for the manufacturing of the veneering overlay and allows for the fabrication of a dental implant from at least one of a metallic material, a ceramic material, an acrylic material, a biocompatible material.

The invention relates to a single- or multi-unit dental restoration, which consists of a support structure and a veneer, which support structure is in particular made from oxide ceramics by means of additive manufacturing, particularly preferably by means of rapid prototyping, wherein the veneer is produced by pressing a ceramic material, such as a glass ceramic or composite material, which is more translucent than the support structure, characterized in that the veneer fills and/or penetrates recesses of the support structure (12) configured as a net or frame structure or as a reinforcement, wherein it is particularly provided that the recesses penetrate through the support structure (12).

The present invention relates to a computer implemented method for aligning a three-dimensional model (6) of a patient's dentition to an image of the face of the patient recorded by a camera (3), the image including the mouth opening, comprising: estimating the positioning of the camera (3) relative to the face of the patient during recording of the image to obtain an estimated positioning, retrieving the three-dimensional model (6) of the dentition of the patient, rendering a two-dimensional image (7) of the dentition of the patient using the virtual camera (8) processing the three-dimensional model (6) of the dentition at the estimated positioning, carrying out feature detection in a dentition area in the mouth opening of the image (1) of the patient recorded by the camera (3) and in the rendered image (7) by performing edge detection and/or a color-based tooth likelihood determination in the respective images and forming a detected feature image for the or each detected feature, calculating a measure of deviation between the detected feature images of the image taken by the camera (3) and the detected feature image of the rendered image, varying the positioning of the virtual camera (8) to a new estimated positioning and repeating the preceding three steps in an optimization process to minimize the deviation measure to determine the best fitting positioning of the virtual camera (8).

The invention relates to a method for producing a dental aid from a thermoplastic film or plate, wherein a digital three-dimensional working model is created in a computer-aided manner using a three-dimensional data set of at least one part of an upper jaw and/or lower jaw.
