Abstract: Disclosed herein is a dental model articulator. The dental model articulator includes: a pair of base members (3) to which dental models (2) are fastened; and an upper fastening means (5) and a lower fastening means (6) to which the respective base members are removably fastened, and which are rotatably coupled to each other by a rotating shaft. A fastening hole (8) is formed through the end of each of the base members. An insert rod (9) is provided on each of the upper fastening means and the lower fastening means and is fitted into the fastening hole of the corresponding base member. Each of the upper fastening means and the lower fastening means includes an auxiliary fastening means (10) for pushing the corresponding base member so that pressure is applied to the base member toward the insert rod, thus increasing a base member fastening force.
