    Reference SL Articulator and Face Bow Systems Eccentric articulator programming Program set Reference SL 06-231310 (complete program set) Composed of: 06-231321 TCI insert- black (straight, retrusive open) 06-231322 TCI insert- white (straight) 06-231323 TCI insert- yellow (curve A – slight curve)
  • Page 38 Instruction Manual Programming eccentric movement tracks into the Reference SL articulator is carried out with the Reference SL program set. Programming can be based on an average value or, preferably, on individually ascertained mandibular joint data (CADIAX), but can also be based on other data, including therapeutic crite- ria.
  • Page 39 Reference SL Articulator and Face Bow Systems To adjust the angle, first loosen the condylar housing fixing screw. Set the desired value on the scale, then tighten the screw again. Fixing and adjusting the TCI insert: Simply pull out the old insert from the groove and slide in the new insert.

The protrusion stop is attached to the condylar element of the articulator from the outside and closed by clicking it in over the articulator axis. The beveled front of the stop always points in- wards, in order to also allow for asymmetric po- sitions.
