Abstract: An acquisition kit including: a mobile telephone; a mobile telephone holder including: —a spacer opening via an oral aperture, intended to be inserted into the user's mouth, and via an acquisition aperture, and —an adapter fastened to the spacer and defining, with the spacer, a chamber opening via the oral aperture and via an adapter aperture, the adapter including a base to which the mobile telephone is rigidly but removably attached in an acquisition position in which the objective lens of the mobile telephone has an at least partial view of the oral aperture, through the adapter aperture and the acquisition aperture, the oral aperture having a curvature about a vertical axis in the service position, the radius of the curvature being greater than 20 mm and less than 80 mm.

In the kit, the mobile telephone is clamped onto the base and the adapter includes a plate movably mounted on the base and on which the spacer is rigidly affixed.

Abstract: A dental retractor including: right, left, upper and lower flanges extending around a retractor opening and intended to rest, in a service position, on the right labial commissure, the left labial commissure, the central part of the upper lip and the central part of the lower lip respectively, of a user. The retractor including: a structure on which the flanges are attached. The retractor including: right and left handles rigidly attached to the right and left ends of the structure respectively, and/or to the right and left flanges respectively, shaped so as to extend outside the mouth of the user in the service position. The structure and/or the attachment of the flanges on the structure is/are shaped so that the horizontal closing force required to bring the right flange and the left flange 10 mm closer together is greater than 5 N.

Abstract: Method for evaluating a dental situation of a patient. The method having the following successive steps: 1) generating an initial model of at least one dental arch of the patient, preferably by means of a scanner; 2) splitting the initial model in order to define a tooth model for at least some of the teeth represented on the initial model and thereby to obtain a split model; 3) determining an initial support curve of the tooth models in the split model; 4) fixing each tooth model virtually on the initial support curve, preferably by computer; 5) modifying the split model by deformation of the initial support curve according to a deformed support curve, so as to obtain a first deformed model, in which the tooth models are aligned according to the deformed support curve; 6) presenting the first deformed model.

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.
