Abstract:
1. A dental articulator, comprising: an upper component; a lower component; an incisal pin coupled to one of said upper and lower components; a joint movably coupling said upper and lower components to each other to effect movement simulation representing mandible movements; an incisal guide table mounted on the other of said upper and lower components, and having a plurality of inclined guide surfaces inclined as progressive steps relative to a reference plane and arranged into a plurality of progressive pairs of inclined guide surfaces, wherein each of said plurality of progressive pairs of inclined guide surfaces forms a V-shape having a common root with other progressive pairs of said plurality of inclined guide surfaces, said incisal guide table and said incisal pin being adjustably positioned relative to each other such that said incisal pin engages a selected portion of one of said plurality of inclined guide surfaces and moves thereacross during the movement simulation; wherein said selected portion of one of said plurality of inclined guide surfaces engaged by said incisal pin applies a supporting force to said incisal pin and which together with a line of application of greatest force component of the supporting force includes an angle corresponding to an angle of the protrusion and laterotrusion guide of a human denture.
