Abstract
An electronic impression tray can be used to obtain three-dimensional and temporal measurements in dentistry. There is a device having optical measurement sensor system, and an electronic system including a central management unit capable of collecting, storing and ordering the data obtained by the sensor systems distributed over all or part of the impression tray. An optical impression of all or part of a dental arch can be obtained with a single or multiple impressions. The tray includes a part having the shape of all or part of a dental arch, and the part can change by virtue of its ability to deform and/or a structure formed by multiple elements that are hinged to one another and/or reversibly assembled and secured to one another, such as to provide the optimal shape.
