Abstract
A process and apparatus for three-dimensional determination of the relative movement between the upper and lower human jaws by affixing at least one reference element to each of the jaws, one of the reference elements having four spatially staggered reference marks and the other having at least three spatially staggered reference marks. The position of each reference marks is optically detected along at least two viewing axes. The relative movement of the jaws is then determined from the change in the mutual position of the reference marks.
