Dentatus Profin PDX Anleitung - Instandhaltung Seite 6

The tip can be used in two different positions:
In position A, the tip is free to rotate to follow contours.
In position B, the tip is fixed in a position of convenien-
ce.
To change a fixed position, pull out the tip slightly, turn
and push it back into a new position. Mount the Profin
handpiece on your micromotor. Internal water or spray
should be turned off on the unit. External water con-
nection can be used with the sprayclip (optional). Spray
is under normal conditions not neccessary for cooling.
If spray is not connected, rinse the area from debris if
necessary with a 3-way syringe.
Rec. speed is 5000-10000 (max) rpm.
Reduction of overhangs and excess cements
Apply the tip on the material to be reduced or finished
in parallell to the tooth contour (1). Start the motor,
move the handpiece slowly up and down, or in and
out in order to remove debris (2). Change for a finer
diamond when the bulk of material has been reduced.
Finish with 30 or 15 micron tip and polish with the
plastic tips together with a polishing paste.
When cementing laminates on incisors, the excess
material in the palatinal concavity can easily and safely
be removed with a bent tip (3).
Adjustment of inlay margins
The margins can normally be finished together with
removal of excess luting material (4). The procedure
is similar to removal of overhangs. If inlays/onlays are
being made on adjacent teeth, finish each tooth after
cementation for easier access, and polish when all
have been cemented.
