The morphological reference plane and the maxillary occlusal plane. (a) Morphological reference plane; the bilateral arbitrary hinge positions and the inferior margin of the nasal wing. (b) Maxillary occlusal plane; the incisal edge of the maxillary central incisor to the distobuccal cusp on bilateral maxillary first molars. (c) The angle formed by the morphological reference plane and the maxillary occlusal plane.
