However, examination of several well-preserved skulls and mandibles (see also Cluver, 1970) has shown that as retraction continues, the lateral horny pads on the lateral symphyseal surface pass behind the caniniform process, and that the pads on the dorsal dentary tables, on each side of the dorsal symphyseal surface (Fig. 45a), move up against the horn- covered areas on the palatines and surrounding portions of the maxilla (Fig. 46). The median palatal ridge of the premaxilla (Fig. 46) now fits neatly into the.
