6.7 Personalized setup of anterior
guidance
For the fabrication of personlized incisal plates, Ivoclar Vivadent
offers a special transparent incisal plate. The plate is made of a
MMA-soluble plastic that bonds with the set-up resin (SR Ivolen).
Anterior guidance plates thus fabricated can always be exactly
repositioned in the Stratos 200.
Procedure
First, mount the transparent 0°
incisal plate. Then, position the
models of the patient for which
the anterior guidance should be
formed in the Stratos 200.
Subsequently, mix appropriate resin and spread it on the incisal
plate. Finally, simulate the registered masticatory movements
(protrusion, retrusion, laterotrusion) with the upper frame of the
Stratos 200. The pattern of movements will thus be scratched into
the resin by the incisal guide rod and recorded after polymeriza-
tion of the resin.
The forming of the natural facing should be done
from excursion to centric. Otherwise, the resin might
be forced out of the incisal plate. Make sure that no
vertical increase of occlusion occurs.
