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.

The viewing device for the interior of a mouth of a patient includes a penetrating ray emitter adapted to take a view of an inner portion located under an outer surface of an organ arranged in the mouth. There is a pair of augmented-reality glasses having an optical glass through which a user of the pair of glasses can see the interior of the mouth and a viewing camera adapted to take an image of what the user sees through the optical glass. A central unit correlates first images corresponding to those taken by the viewing camera with second images corresponding to those taken by the penetrating-ray emitter.

A device for bleaching a part of the human body has a wave-current generator, a plurality of electrodes and a conductive gel. The conductive gel is maintained in contact with the part of the body. An active product is cooperative with the gel so as to be activated under the presence of light or heat. A conductive circuit and a resistor define poles of the electrodes on the container of the conductive gel and the part of the body. The photosensitive bleaching product is activated by applying photonic energy of a wavelength of 400 to 500 nanometers.

After the shape of the zone of implantation in the mouth is obtained by direct impression, micro-sensing or optical impression, a prosthesis or a mold for making a prosthesis is automatically machined by machine tool at a work center with the assistance of a calculator or computer which takes into consideration the shape obtained, the material or materials which are to be shaped, and other parameters such as thicknesses and the like which are essential to the proper shape and configuration of the prosthesis which is thus fabricated. The prosthesis can be a crown, bridge or part or assembly of both.

Method of producing a dental prosthesis

A method and apparatus for taking impressions of a portion of the body which utilizes the projection of a grid of sinusoidal profile onto the body portion of which the impression is to be taken. The projections are phase-shifted and resulting images are memorized and from the memorized images, the variations in intensity resulting from the phase-shift at each given point can be ascertained to enable the configuration of the region to be calculated.

Process and apparatus for taking a medical cast

A method of making a dental prosthesis in which data representing standard tooth shapes and sizes, relationships between teeth and adjacent and occlusive teeth and characteristics for securing a prosthesis to a prepared site, and machining instructions for shaping a blank to the configuration of a dental prosthesis for direct implantation are stored in a computer memory. After preparing a site in the mouth of a patient to receive a dental prosthesis, the dental surgeon projects optically a grating upon said site in the mouth of the patient and generates an interference pattern representing a holistic impression of said site and its relationship to adjacent structures. The interference pattern is converted into data along x,y,z coordinates in a cartesian coordinate system representing machining of a blank to fit said site and matching data obtained by comparing the impression with the computer standards are used to select a best-fit shape and size. A machine tool is numerically controlled with the x,y,z coordinate data and x,y,z coordinate data from the match made by the computer and representing the shape and size of the prosthesis to totally and three-dimensionally fabricate said prosthesis in said machine tool.

Dental prostheses, such as crowns, inlays or dentures are produced automatically based upon an optical impression taken of the oral region wtih nontraumatic radiation. The reflected waves are transformed into numerical data which is used directly to operate a numerically controlled machine in the fabrication process. The process is pertinent to other medical applications as well.
