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.

A process for three-dimensional determination of the relative movement between the jaws, said process comprising steps of affixing at least one reference element to the teeth of the lower jaw and at least one reference element to the teeth of the upper jaw, with one of said reference elements comprising at least four spatially staggered reference marks arranged in three dimensions and with the other of said reference elements comprising at least three spatially staggered reference marks; optically detecting the position of each reference mark in relation to each of the other reference marks along at least two viewing axes, and determining the relative movement of the jaws from the change in the mutual position of the reference marks.
