Protrusive Adjustments
The inclination of the protrusive condy-
lar path can be adjusted by loosening
the protrusive adjustment lockscrew.
The protrusive condylar path inclination
scale is below the protrusive adjustment
lockscrew and is calibrated in incre-
ments of 5 degrees (fig. 8).
Immediate Side Shift Adjustment
The medial fossa wall can be displaced
straight medially by means of the imme-
diate side shift adjustment. The scale for
the immediate side shift adjustment is
lateral to the adjustment lock screw on
top of the fossa (fig. 9). The scale is a
Vernier scale calibrated in .2 millimeter
increments. The scale reads medialward
from its lateral extremity.The index in fig.
10 indicates an immediate side shift set-
ting which is more than 0 but less than 1
full millimeter. By reading the Vernier
scale on the lower portion of the scale
medialward from the index it can be
determined that the immediate side shift
is .6 of a millimeter since it is the third
graduation that lines up with a millimeter
graduation on the upper portion of the
scale.
Progressive Side Shift Adjustment
The angle of inclination of the medial
fossa wall to the sagittal plane be
adjusted by loosening the progressive
side shift adjustment lockscrew and
moving the insert from 5 to 15 degrees.
The scale for the progressive side shift
adjustment is anterior to the adjustment
lockscrew and is calibrated in 5 degree
increments. (fig. 11).
