Work Instruction for the Locator® Retentive System - Camlog

appropriate impression material (e.g.
polyether or silicone) to ensure that the
impression caps will remain securely in the
impression.
In the dental lab:
The matching analog is selected as described
in the diagram "In the dental lab: Selection
of matching analogs" on page 7, and
inserted into the impression caps in the
impression. Fabricate the master cast and
ensure the fixation of the defined position
and occlusal height of the denture and
occlusal plane.
After the master cast is finished, place the
white block-out spacer (supplied with the
male processing package) over the functional
areas of the Locator ® analogs to prevent
acrylic from penetrating into the retention
housing.
Mount the retention housing with the black
processing replacement male over the
previously inserted block-out spacer until
pressure is felt. The black processing replacement
male will ensure both secure seating
for the retention housing and resilience.
Undercuts between the retention housing
and surrounding tissue which the blockout
spacer does not reach must be blocked
out. Do not allow any acrylic to enter
the retention housing during preparation!
Do cure the retention housings into the relieved
denture base.
After the denture has been finished and
polished, remove the black processing replacement
males as described in "Insertion of
the replacement males" on page 8, and
exchange them with the matching replacement
males.
Insert the finished denture and check the
occlusion.
7.3.3 Adjusting an existing denture
with Locator ® components in the
dentist’s office
Locator ® components can also be incorporated
into an existing full denture in the dentist's
office. Locator ® abutments of matched
diameters and gingival heights are inserted in
the manner described in 7.1 "Locator ® abutment
insertion" on page 6.
Locator ® abutments must be secured
during insertion in the mouth to prevent
aspiration (e.g. with dental floss).
Locator ® abutments with 3.3 mm diameter
are tightened with a torque of
20 Ncm. Abutments with 3.8, 4.3, and
5.0 mm diameters are tightened with a
torque of 30 Ncm. The abutments must
be retightened after 5 minutes with the
respective torque.
Place the white block-out spacer (supplied
with the male processing package) over the
functional areas of the Locator ® abutments
to prevent acrylic from penetrating into the
retention housings.
Mount the retention housings with the black
processing replacement males over the
previously inserted block-out spacer until
pressure is felt.
The black processing replacement male will
ensure both secure seating for the retention
housing and resilience.
Undercuts between the retention housing
and surrounding tissue which the blockout
spacer does not reach must be blocked
out. Do not allow any acrylic to enter
the retention housing during preparation!
