About semi-adjustable articulators
A semi-adjustable articulator allows adjustment to simulate the movements of the lower jaw; the glossary names it a Class III articulator. A Class III instrument simulates the paths of the jaw joints by using averages or mechanical equivalents for all or part of the motion. It lets the casts be oriented relative to the joints, and it may be of arcon or nonarcon design.
An articulator is a mechanical device that simulates the movements of a patient's upper and lower jaws. Plaster casts of the teeth and gums are placed in it to reproduce the bite and the way the jaws meet. The FDA lists the articulator as a Class I device (21 CFR 872.3150).
The Glossary of Prosthodontic Terms sorts articulators into four classes by how much jaw movement they can reproduce. Class I is a simple holding instrument that accepts a single static registration; Class II allows horizontal as well as vertical motion but does not relate it to the jaw joints. Class IV, the fully adjustable articulator, accepts three-dimensional dynamic registrations.
How the types of articulator differ
- Semi-adjustable articulators — Adjustable to simulate jaw movement, where the simplest class only holds the casts in one static position.
- Disposable articulators — A small hinge made for a single case.
What to look at when choosing an articulator
Adjustment: the class tells how much movement the instrument can reproduce, from a single static position to recorded three-dimensional movement.
Arcon or nonarcon: an arcon articulator carries the condylar elements in its lower member and the condylar paths in its upper member, as in the jaw. In a nonarcon design the condylar element is part of the upper member.
Facebow: a facebow records how the upper arch sits relative to anatomic reference points and transfers that relationship to the articulator.
Mounting: casts attach to the upper and lower members through removable mounting plates of metal or resin.
