Abstract
An articulator that can be recalibrated easily in the field. The articulator has left and right condyle elements that resemble barbells, with an inner sphere, an outer sphere, and a shaft connecting the inner and outer spheres together. In the preferred embodiment, the outer spheres are releasably fixed to the lower frame member by clamping members, and the inner spheres are pivotably mounted to the upper frame member. To calibrate the articulator, the clamping members are loosened, an alignment fixture is installed to ensure that the articulator is in proper alignment, and then the clamping members are tightened into position, fixing the outer spheres in the properly-aligned position.
