The posterior articulating assembly is characterized by a ball and socket joint and a pivot joint. The ball and socket joint has a socket member which is operably coupled to the pivot joint and a ball member which is operably coupled to a first teeth cast. The pivot joint has a pivot member operably coupled to a support member for joining the pivotal joint to a second teeth cast. The anterior incisal support assembly has an incisal pin operably joined to the first teeth cast and an incisal plate, which cooperates with the incisal pin, joined to the second teeth cast. The mold assembly has a plurality of molds each having an aperture in each of an anterior and posterior portion of the mold and an associated alignment protrusion, in close proximity to the aperture, for aligning joining members, to be cast into the first and second teeth casts, for connecting the first and second teeth casts to the ball member and the support member.
