Description

SIMULATING NATURAL MOVEMENT PATTERNS

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 an 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 a 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 that guide the double cone.

A vertical-sagittal one on the retrusion bar (red) and a horizontal-sagittal one on the joint disk (green).

The vertical-sagittal edge on the retrusion bar touches the inner cone (red) whereas the horizontal-sagittal edge guides along the apex of the double cone (green).

As a result, with lateral movements, the double cone is not only guided into a physiological, three-dimensional movement via the horizontal guide edge of the joint disk (green), but also via the vertical guide edge on the retrusion bar (red).

THE BENNETT MOVEMENT

The condyle moving on the non-working side is the mediotrusion condyle: during a lateral movement (mediotrusion) the moving condyle moves forward in a downward direction.

The condyle resting on the working side is the laterotrusion condyle: this side is used for chewing and the teeth are in occlusion. This condyle can rotate around the vertical axis and also move laterally.

The CA 3.0 allows virtually identical natural 3D simulation of the lateral and Bennett movement. Functional hyper-contacts are avoided.

DESIGN

Handy, light-weight, and robust aluminum construction. This design facilitates simple, physiological operation procedures. Heavily stressed elements such as the joint and vertical pin are made of stainless steel. The incisal plate is made of durable POM acrylic.
