INSTRUCTIONS FOR SETTING ADJUSTMENTS

The "AL" articulator (48400) is a semi-adjustable, arcon articulator with adjustment settings for Bennett Angle and condylar inclination.

You will need to mount magnetic SPLITEX® plates (46100) onto the articulator prior to using the unit for the first time. (see separate instructions). Axis-related models can then be mounted to the articulator by using a "buffer plate" in between the magnetic plates and the quick-setting plaster that will hold the models.

"AL" adjustment ranges:

Bennett Angle: -5º to 30º

Condylar Inclination: -20º to 60º

Accomplishing settings and movements:

Lateral movement for replication of excursions can be achieved by unlocking the centric condyle lock in front of either condylar housing to allow the condyle balls freedom of movement along the condylar pathways.

Condylar inclination setting adjustments can be made by loosening the lower allen screws at the rear of the upper arm of the articulator. Then turn the condylar housing to the appropriate inclination setting (lining up the front of the triangular point with the correct hash mark), and relock the screw heads.

Bennett Angle setting adjustments can be made by loosening the allen screw on top of either condylar housing, and turning the dial until the white indicator line matches up with the desired setting. Then relock the screw.
