A dental articulator (5) capable of reproducing or analyzing a physiological occlusion status by implementing a pressure receiving function and a traction function capable of operating in all the motion directions equivalently provided by a jaw joint function of a living body with a teeth plaster model fitted between upper and lower jaw frames, comprising an occlusal plane table (8) having the same anteversion angle as the occlusal plane oblique angle of a living body; a bite analysis plate (9) on which average positions of a spew center (91) and a posterior motion axis (92) are set at a plurality of positions and they are sketched in pairs with the average positions of the spew center on one side and those of the posterior motion axis on the other side of the plate; an incisal guidance plate (56) in which an inverted conical slope for mapping front-and-rear, right-and-left inclinations of the cusp is cut to allow the tip of an incisal guide to slide; and a transform plate (1) which is fitted using a lower jaw frame (52) as a base, wherein the teeth plaster model (7) of a lower jaw is mounted on and fitted to the transform plate (1) to effect a shift operation, thereby reproducing a physiological occlusion status in conjunction with an intercuspal position and a posterior occlusion position of a living body. <IMAGE> |
