Abstract: Methods and systems are described that mark and/or correct margin lines and/or other features of dental sites. In one example a three-dimensional model of a dental site is generated from intraoral scan data of the dental site, the three-dimensional model comprising a representation of a preparation tooth. An image of the preparation tooth is received or generated, the image comprising a height map. Data from the image is processed using a trained machine learning model that has been trained to identify margin lines of preparation teeth, wherein the trained machine learning model outputs a probability map comprising, for each pixel in the image, a probability that the pixel depicts a margin line. The three-dimensional model of the dental site is then updated by marking the margin line on the representation of the preparation tooth based on the probability map.

Abstract: Abstract Method and apparatus for taking, using and displaying dental information including information extracted from three-dimensional (3D) volumetric models of a patient's dental arch. A 3D volumetric model may include surface (e.g., colour) information as well as information on internal structure, such as near-infrared (near-IR) transparency values for internal structures including enamel and dentin.

Abstract: Un procedimiento que comprende: mostrar un modelo (617) tridimensional (3D) de la arcada dental de un paciente; mostrar una ventana (1003, 1005) de visualización sobre al menos una porción del modelo 3D de la arcada dental del paciente, donde la visualización de la ventana (1003, 1005) de visualización sobre una porción del modelo 3D de la arcada dental del paciente comprende la visualización de un bucle (1401) a través del cual se puede ver la porción del modelo 3D de la arcada dental del paciente; recibir, de un usuario, un cambio en una posición relativa entre la ventana (1003, 1005) de visualización y el modelo (617) 3D del arco dental del paciente; identificar, a partir del modelo (617) 3D de la arcada dental del paciente y de una pluralidad de imágenes de la arcada dental del paciente tomadas desde diferentes ángulos y posiciones relativas a la arcada dental del paciente, una imagen del IR cercano (1005) tomada en un ángulo y posición que se aproxima a un ángulo y posición relativos entre la ventana (1003, 1005) de visualización relativa y el modelo 3D de la arcada dental del paciente; y mostrar la imagen (1005) identificada del IR cercano tomada en el ángulo y la posición que se aproxima al ángulo y la posición entre la ventana (1003) de visualización en relación con el modelo (617) 3D de la arcada dental del paciente.
