Abstract

A surface mapping and generating device which has devices for the process and/or cost optimization, in particular raw material recovery devices, an automatic control of the intensity of a used laser light, devices for carrying out a calibrating procedure by evaluating overlap errors at matching points, devices for archiving especially three-dimensional data of the jaw and/or for modeling the bite position of the upper and the lower jaws, devices for the optimized preparation of at least one dental stump for the production and placement of a dental prosthesis thereon and/or devices for taking into consideration the bite position of the upper and lower jaws. It can be provided that the devices for the process and/or cost optimization are designed to ensure that two half frames showing different positions or views are evaluated, whereby preferably a pulsed laser for exposure purposes is included and/or that an image recording device, in particular a CCD chip, is arranged so as to ensure that lines, taking into account the Scheimpflug angle, are located perpendicular to the direction of travel of a measuring table. Methods according to the present invention use such devices and functio…
