Non-Arcon Dental Articulator

The Articulator CA 3.0 excels through its simple handling and precision. It was designed along the camper plane. It runs parallel to the occlusion plane, thus giving unambiguous and practical reference for daily work.

The temporomandibular joint – an overview

The temporomandibular joint is both a rotating and sliding joint with two types of movement: the rotation or hinged axis as well as the translational or sliding movement. The most common form of movement is a combination of both types of movement. A rotation with simultaneous translation – a rotary sliding. Interaction between the two temporomandibular joints allows rotational movement along axes other than the hinged axis. Three axes of movement can be determined.

A horizontal-transversal joint axis as simple hinged axis (green).
A vertical joint axis for the respective condyle on the side of lateral movement (blue). The condyle on the opposite side performs a downward and sliding movement forwards.
A horizontal-sagittal joint axis (black) for the respective condyle on the side of lateral movement, with simultaneous lateral movement of the joint head of the opposite side downwards and forwards.

The CA 3.0 joint is analog to the natural temporomandibular joint

The shape of the natural joint head is copied and simulated by the double cone in the Articulator CA 3.0. This avoids unphysiological, straight movement patterns in lateral and transverse motion sequences.

Simulating natural movement

The CA 3.0 is equipped with two guide edges which guide the double cone.
