Preventative Maintenance of the Hanau Wide-
1. Use petrolatum (VaselineR or Model Release AgentR) to lubricate and protect the articulator.
This can be easily applied using a few cotton swabs.
2. Loosen the larger of the two lock nuts to the guide table. These are located on the underside of
anterior portion of the lower member of the articulator. Remove the guide table from the
3. Loosen the guide table in its cradle by turning the smaller of the two lock nuts on the bottom
of the table. This will free up the guide table so that it will move freely in the anterior-posterior
4. Apply the petrolatum with a dry cotton swab into the slot that is exposed on the underside of
the guide. With the table loosened, move it backward and forward in its guide to spread the
petrolatum and lubricate the entire surface.
5. Loosen the lateral wing lock nuts and apply the petrolatum liberally to the screw threads.
Move the lock nut backward and forward on the screw to spread the petrolatum and lubricate the
6. Lubricate the track under the lateral wing. Turn the end of the lock screw to move the wing up
and down in its guide to spread the petrolatum and lubricate the entire surface.
7. Apply the petrolatum to the ends of the lateral wings and any other area that moves against
another part. This lubricant will actually serve to prevent the corrosive effect of plaster against
bare metal surfaces.
8. Remove the mounting ring screws from the upper and lower members of the articulator.
Lubricate the hole and along the shaft of the mounting screws with a cotton swab. Note: These
mounting screws are not interchangeable. The longer one goes in the top, the shorter one in the
9. Use a cotton swab to lubricate the areas that will be covered by the mounting plates and the
incisal guide table.
10. Loosen the horizontal condylar guide lock nut on the upper member of the articulator. Apply
lubricant within the guide slot and track. Move the horizontal guide element backward and
forward to spread the lubricant.
11. Loosen the centric lock nut on the horizontal condylar guide on the upper member of the
articulator. Apply lubricant to the condylar ball and within the slot and track. Move the upper
member of the articulator backward and forward to spread the lubricant.
12. Loosen the lock nut on the lateral condylar guides on the upper member of the articulator.
With a thumb, push against the lock nut to lower the guide down enough to admit the tip of a
cotton tip applicator between the upper member of the articulator and the base of the guide.
Move the lateral guide clockwise and counterclockwise to spread the lubricant.
13. Loosen the lock nut on the incisal guide pin on the upper member of the articulator and
remove the guide pin. Lubricate the hole on the upper member of the articulator, the set screw,
and the guide pin itself. Replace the guide pin and set it at zero.
14. After each use and before the articulator is put away it must be thoroughly cleaned of all
gypsum products and can be easily protected by spraying it with vegetable oil. An easy way to
apply this is to use a spray can of PAMR, the same product you use to protect your frying pan.
The articulator should also be sprayed again prior to each use to freshen the protective coating.
