When a patient moves from protrusion back to maximum intercuspation (MIP), what is the resulting relationship of the teeth?

Maximum intercuspation (MIP) is defined as the position of maximum interdigitation of the teeth, characterized by a cusp-to-fossa (or cusp-to-marginal ridge) relationship. When the mandible returns from a protrusive position to MIP, the teeth settle into this cusp-to-fossa occlusal relationship. In protrusion, the teeth may be in an edge-to-edge or cusp-to-cusp relationship, but at MIP they are in cusp-to-fossa.
