General Information: Artex® Type TR

Bennet Angles are adjustable from 0° to 20°. The condyle radius is milled to 19mm, and the condylar inclination is adjustable from 15°  to 60°. Condyles are held in their center of rotation by closing the centric locks. This unit provides the same adjustments as the TK, plus immediate sideshift adjustment (0 to 4mm), and protrusive (0 to 6mm) and retrusive (0 to -2mm) indication.

INSTRUCTIONS FOR USE

The "TR" articulator is a semi-adjustable non-arcon articulator with the additional functions of retrusion and protrusion.

The "TR" articulator features a bipartite condyle carrier which can be guided out of a fixed pivot in both directions, pro- and re-, i.e. forward and backward.

The centric position is ensured by the centric lock screw. When completely screwed in, it immobilizes the carrier in centric (zero-position). When screwed completely out, by means of a special allen wrench, the condylar path "falls" into retral position (as it is a non-arcon type, it goes forward). Retrusion is brought backward "by hand", and is then fixed by the jam screw. The centric lock screw fixes the condyles in quasi-zero either in retrusive or protrusive position which is very helpful within these eccentric positions for the handling of this instrument.

1. Principle of construction:

The condylar box is divided into two parts. If the centric screw is completely open, there will be space for condyle retrusion of up to 2 mm.

2. Centric screw:

If the centric lock screw is completely screwed in, the condyle is at zero position (centric). Loosening the jam screw allows protrusion of up to 6 mm.

3. Side effect:

Adjustment of inclination is effected by slot-and-key guidance.
