Dental model articulator

The articulators of the present invention provide relative manipulation of dental models for simulation of occlusal and masticatory movements of the mouth. The full arch articulator with a removable wall consists of four parts-a lower part, an upper part, a middle part, and a rear part. The lower part is comprised of a full arch box, a pair of female hinge assemblies, and an incisal guide plate. The full arch box has an open bottom and an insert at the top with a series of grooves. The upper part is comprised of a spherical inner surface, a spherically concaved area on the outer surface, a square box with an open top, a vertical support with sides of cylindrical halves, and an incisal pin hole. The middle part is snap-seated on top of the full arch box in the lower part. The rear part is comprised of a pair of extension arms to receive the upper part for connection and a male hinge bar which is connected to the lower part. The quadrant articulator with a detachable wall consists of two parts-an upper part and a lower part. The upper part is comprised of an elongated channeled surface, a deformable bracket, a snap-fit female hinge assembly, and a platform with a hole. The lower part is comprised of an elongated block with two rows of pin holes, two rows of struts, pin position indicators, a pair of model lifters, a tray positioning plate, a vertical stop pin holder, a snap-fit male hinge assembly, and a platform.
