Abstract: A flexible mold and method of forming a base defining either a full base or quadrant base of a dental model is provided with a perimeter member for defining the side walls of the base and a shelf extending inwardly from the rear side wall for delineating a slot at the rear of the base, which slot is usable for adhering an arm of an articulator. The configuration of the slot and/or the rear side wall of the base is striated for better adherence with the attached articulator.

Abstract: An articulator for casts of a dental model correlates the casts with the condition to be redintegrated throughout a full range occlusal and masticatory registration. The articulator includes hinged mirror image flexible brackets; each bracket has a base and arms of nonuniform cross section to encourage localized flexure of the brackets. Each base of the brackets supports a sphere to be positioned within a respective mounting attached to each cast. Each of the spheres may include at least a partially circumferential groove for distributing by capillary action or wicking an adhesive intermediate the sphere and the engaged cavity to secure the articulator to the casts after alignment of the paired casts. Simulating and tracing the paths of natural occlusal and masticatory registration is effected by pivotal movement about the hinge line between the brackets and flexing of the brackets forming the articulator.

Abstract: An articulator for casts of a dental model correlates the casts with the condition to be redintegrated throughout a full range occlusal and masticatory registration. The articulator includes an hinged two part flexible element, each of which parts may be a mirror image of the other, or a one piece hinged flexible element having like opposing integrally connected parts. Each opposed end of either type of element supports a sphere to be positioned within a respective one of a cavity formed in each cast or in a respective mounting attached to each cast. Each of the spheres includes at least a partially circumferential groove for distributing by capillary action or wicking an adhesive intermediate the sphere and the engaged cavity to secure the articulator to the casts after alignment of the paired casts. Simulating and tracing the paths of natural occlusal and masticatory registration is effected by pivotal movement about the hinge line and flexing of the articulator.

Abstract: A mounting cooperatively associated with the rear face of each cast of a pair of dental model casts interconnects one of opposed parts of an articulator to secure the articulator to the dental model. Each mounting includes at least one cast insertable locking member supporting one element of a ball and socket joint which joint is disposed intermediate the respective cast and the articulator.

Abstract: A preformed dental model base, for use with an articulator, characterized by a flat bottom surface and a flat elevated upper platform surface spaced above other upper portions of the base.

Abstract: A flexible mold defining either a full base or a quadrant base of a dental model includes a perimeter member for defining the side walls of the base and a shelf extending inwardly from the rear side wall for delineating a slot at the rear of the base, which slot is useable for indexing an arm of an articulator to be attached to opposed ones of the bases. A variant of the mold permits the formation of a pedestal for supporting a matching tooth die. A method of removing the molded article from the mold is also disclosed and claimed.

Abstract: An articulator for casts of a dental model correlates the casts with the condition to be redintegrated throughout a full range of occlusal and masticatory registration. The articulator includes an hinged two part flexible element, each of which parts is a mirror image of the other, or a hinged one part flexible element having like opposing halves. Each opposed end of either type of element supports a sphere to be positioned within a respective one of a cavity formed in each cast and adhesively secured thereto after alignment of the paired casts. Simulation and tracing the paths of natural occlusal and masticatory registration is effected by pivotal movement about the hinge line and flexing of the articulator.The present application is a continuation-in-part application of a copending application entitled "DENTAL MODEL ARTICULATOR", Ser.
