Abstract: A typodont having one or more removable teeth which may be simultaneously locked in place by a single locking ring. The typodont includes a jaw member having one or more openings for receiving the shanks of the individual removable teeth and a parabolic arch-shaped groove cut in the jaw member which is in communication with each of the openings. The removable teeth each have a notch which is cut in the shank of the tooth with the notch being in alignment with the groove when the tooth is inserted in a jaw member opening. A locking ring having a locking portion which is shaped like the jaw member groove can be placed into the groove so that the locking portion will engage each of the notches in the shanks, thereby locking the removable teeth into place.
