Described are a process and device for the production of individual tooth replacement parts, the control signals being generated by computer from measurements of the tooth imperfections. The device is characterized by a control unit (19) which controls the movement of the measurement beam (8) and the generation of three-dimensional images of mutually opposite areas on the upper and lower teeth by point-by-point scanning, a measurement store (22) for the storage, as a first data record, of the images of the lower and upper teeth in the form of individual measurement values corresponding to the measurement points, a pressure-sensitive tooth-impression film (27), a unit for the detection, in two dimensions, of areas of the tooth-impression film in which a given contact pressure is exceeded when a patient bites and the storage of these coordinates as a second data record, a processor unit (25) to determine areas in which the vertical components of the measurements, determined separately for the upper and lower teeth, have matching height components, allowing for the horizontal reference levels for the upper and lower teeth and the different measurement directions, and the storage of these two-dimensional data in a third data record, and electronic components for superimposing as closely as possible the second and third data records, the geometrical values of the second data record being inscribed in the first data record as completely as possible as regards their coordinates. |
