<p>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 (18, 20); each bracket has a base (22, 24) and arms of nonuniform cross section to encourage localized flexure of the brackets. Each base (22, 24) of the brackets supports a sphere (26, 28) to be positioned within a respective mounting (38, 40) attached to each cast. Each of the spheres (26, 28) may include at least a partially circumferential groove (64, 66) for distributing by capillary action or wicking an adhesive intermediate the sphere and the engaged cavity (42, 44) 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 (18, 20) forming the articulator.</p> |
