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 function correspondingly. In addition, the invention also makes available a patient data archiving system which comprises a chip card and/or decentralized data storage systems especially for dental data.

Claims

1. A device for mapping a surface of a jaw model, said device comprising:

a template for adjusting said jaw model to be mapped, wherein said template comprises different adjustment contours, said adjustment contours being suitably placed on a material from which said template is made, and wherein said different adjustment contours are adapted such that jaw models of different diameters may be adjusted.

2. The device as set forth in claim 1, wherein said template is made of transparent plexiglass.

5. The device of claim 1, wherein said adjust contours are engraved into said material from which said template is made.

3. A method for mapping a surface of a jaw model, said method comprising:

adjusting a jaw model to be mapped with a template, wherein said template comprises different adjustment contours, said adjustment contours being suitably placed on a material from which said template is made, and wherein said different adjustment contours are adapted such that jaw models of different diameters may be adjusted.

4. The method as set forth in claim 3, wherein said template is made of transparent plexiglass.

6. The method of claim 3, wherein said adjust contours are engraved into said material from which said template is made.

7. A device for mapping a surface of a jaw model, said device comprising:

a template adapted to adjust said jaw model to be mapped, wherein said template is situated above a rotating plate adapted to receive said jaw model, wherein said template is comprised of a transparent material comprising a plurality of adjustment contours engraved therein, wherein each of said plurality of adjustment contours comprises a different size, and wherein each of said plurality of contours is adapted to position a jaw model in a correct position for scanning based on a diameter of said jaw model.
