ABSTRACT OF THE DISCLOSURE The invention relates to a process for a three- dimensional determination of the relative movement between an upper jaw and a lower jaw and to a measuring arrangement for embodying this process. According to the invention, the at least two-dimensional determination of the relative movement between the upper jaw and the lower jaw occurs preferably in that, on the side of this jaw facing the optoelectric device in a two-dimensional determination of the movement at least two, and in a three-dimensional determination of the movement at least three or four spatially staggered reference marks are places on each jaw and in the latter case the mutual position the reference marks exhibit on each jaw and the position of the reference marks on one jaw relative to the reference marks on the other jaw, as well as the changes in these positions, are optically detected and from this, preferably by using a computer (computer-aided), the relative movement of both jaws is determined.
