Abstract: A system for manufacturing an orthodontic appliance. A scanner for creating a numerical three-dimensional initial reference model of at least a part of a patient's arch including one or more teeth. An image acquisition device for acquiring at least one two-dimensional updated image of the arch. The image acquisition device is positioned and oriented in space, relative to the teeth, under actual acquisition conditions. A computer for creating a numerical three-dimensional objective reference model, corresponding to a desired positioning, at a time point of a treatment, of the teeth, and deforming the initial reference model by moving one or more teeth of the initial reference model, to obtain an updated reference model corresponding to the positioning of the teeth on the two-dimensional updated image. A device for manufacturing an orthodontic appliance, based on a comparison, executed by the computer, between the updated reference model and the objective reference model.

Abstract: A method for adjusting/monitoring an orthodontic appliance worn by a patient. Creating a numerical three-dimensional reference model of at least a part of a patient's arch. Creating a numerical three-dimensional reference model of the teeth of the at least a part of the patient's arch. Acquiring at least one updated image, under actual acquisition conditions, and searching, by deformation of the initial reference model, for an updated reference model corresponding to the positioning of the teeth during the acquisition of the updated image. Determining, depending a comparison model corresponding to an anticipated positioning of the teeth, a comparison model. Comparing the updated reference model with the comparison model. If comparison leads to an unsatisfactory result, creation of a replacement orthodontic appliance, by modification of the orthodontic appliance worn or by creation of a new orthodontic appliance, the replacement orthodontic appliance being configured accordingly.

Abstract: A method for optimizing initial discriminating information extracted from a two-dimensional image of the patient dental arches, referred to as “acquired image”, by a three-dimensional digital reference model of at least one portion of a patient arch, the method including the steps: C1. assessing quality of the initial discriminating information and quality threshold, filtering to keep only the initial discriminating information that has quality higher than the quality threshold, and defining “the discriminating information to be tested” as the initial discriminating information selected; C2. testing consistency between the discriminating information to be tested and reference model; C3. assessing test result and, in accordance with the assessment: adding discriminating information that was not kept to the discriminating information to be tested and/or deleting discriminating information from the discriminating information to be tested, and then returning to step C2. or; defining the optimal discriminating information as the discriminating information to be tested.

Abstract: A method for predicting a future dental situation for a patient. Acquiring historical data including at least: previous time point and context parameter values. Acquiring at a time point all the data related to the current dental situation, including at least: the current time point, context parameter values at the current time point, statistical analysis of the historical data and the current data, so as to predict, at a future time point, at least one future dental situation for the current patient. Depending on the future dental situation, (re)evaluation of the benefit of an orthodontic treatment. Steps may include creating a three-dimensional digital reference model, acquiring at least one two-dimensional image, analysing each updated image and creation, searching, for each updated image, and collecting data relative to the updated reference model and relative to the orthodontic appliance.
