Abstract: A dental articulator for use with a dental stone comprising; a lower jaw member and an upper jaw member mounted to the lower jaw member. One of said jaw members is provided with a pivot post and a key member and the other jaw member defines a apertre which fits around the pivot post and a key way which selectively receives the key member for positioning the jaw members in a selected fixed positional relationship. A plurality of slots are formed in each jaw member to give the jaw member flex in the vertical and lateral direction and serrations are formed in the end of each jaw member to prevent rotation out of the dental stone. A dowel holding rod with associated dowel pins mounted thereto is mounted to the ends of each jaw member for mounting in selective jaw casts in one embodiment of the invention.
