Process and apparatuses for reproducing jaw movements

摘要

To reproduce jaw movements, electric distance measuring devices are fixed at the lower jaw and the upper jaw in the mouth of a patient to measure, with relative movements between upper and lower jaws, the distances between defined points of the two jaws and to supply the data to a memory. In accordance with the recorded measuring data a mobile portion of an articulator carrying a jaw model is so guided that it reproduces the recorded sequence of motion, the combinations of the measured distances between the defined points of lower jaw and upper jaw being repeated in the same way as in the measuring operation.
