[Articulation theory--today].

The classic theory of articulation (Hanau's quintet and Thielemann's formula) was to be modified on the basis of more exact methods of registering the mandibular movements. In the course of protrusion, laterotrusion and mediotrusion, different factors determine direction and inclination of the individual functional dental facets. The laws of articulation are redefined with regard to laterotrusion.
