Articulation (dentistry)
In dentistry, articulation is the shifting of the rows of teeth against each other with tooth contact by sliding movements of the lower jaw. The shape of the sliding movements depends, among other things, on the position of the teeth, the shape of the cusps and the joint path in the jaw joint.
Articulation foils
With thin colored ribbons - articulation foils or occlusion foils - (approx. 12 µm thick), the contact points and the slideways of the teeth can be visualized and thus checked. For this purpose, closing and chewing movements are carried out with a film located between the teeth. With articulation foils in different colors, the chewing patterns during the closing and chewing movements are reproduced on the occlusal surfaces. Disturbing contacts and slideways can be sanded away at the colored areas in order to create a balanced articulation. In addition, a shimstock film without color coating is available for the final occlusion test. The film is characterized by high tear resistance and a thickness of only 8 µ. With normally closed rows of teeth, you should still be able to pull this foil through. With muscle tone, the foil is held in place by the teeth.
The term articulation is gradually being replaced in dentistry by the synonymous term dynamic occlusion (as opposed to static occlusion ).
