Mandible - The two axis of movement should pass through the first molar

zygomatic bone:

The zygomatic bone acts as an integration place for the influences of the occipital bone, the sphenoid bone and the facial skull. A longitudinal rotational axis runs from posterior to anterior and from lateral to medial, and a vertical axis goes through the frontal process. The frontal process moves anterior lateral.

The maxillary process moves externally and anterior.

Intraosseous adaptation of the zygomatic bone to a global expansion and retraction of the skull.

mandible:

The two axis of movement should pass through the first molar. The condylar processus move posterior medial, the angles move lateral, anterior and caudal. The tip of the chin moves posterior.

Intraosseous adaptation of the mandible to a global expansion and retraction of the skull.
