SEITE 7 - 148 x 210 mm - 3100021788/01 - SCHWARZ - 20-052 (kn)
Remove the light guide by turning slightly and pulling
it out of the handpiece.
Positioning the Light Guide
Rotate the light guide into the desired position for
polymerization.
To make full use of the light intensity provided, place
the light guide as close to the filling as possible.
Avoid directly contacting the filling material.
- Keep the light guide clean at all times to obtain full
light intensity.
- Damaged light guides substantially reduce
the light intensity and must be replaced
immediately! Sharp edges may cause serious
injury!
Testing of Light Intensity
Depending on the layer thickness of the filling material
being cured, it is possible to check the function of the
curing light using curing disks for composites:
Place the curing disk on a mixing pad.
Fill your preferred composite into a bore of the curing
disk at least twice as deep as the recommended
layer thickness of your composite.
Cure the composite in the curing disk for the time
recommended by the composite manufacturer.
Scrape off soft material from the bottom of the cured
material with a plastic spatula.
The solid thickness of the cured material in the curing
disk divided by two is the layer thickness which can
be properly cured.
If you have doubts about the correct function of your
curing light, clean the light guide and the protection
glass in the light guide mounting hole and ensure
proper fit of the light guide in the handpiece and
repeat the intensity test.
If you have still doubts about the correct function of
your curing light, contact 3M service.
The curing disk must only be used to test the
function of the curing light! For clinical depth of
cure, please refer to the Instructions for Use of
the filling material.
Commonly available devices for measuring light intensity
can also be used; their measurement values should not
be regarded as absolute values. When such devices
are used, we recommend recording the intensity of the
curing light before its first use and measuring it again at
regular intervals so that any decrease in light intensity
can be detected. The light intensity testing unit in
an Elipar DeepCure-S base station has a device for
measuring intensity on a percentage basis.
Recommended Cure Techniques with 3M Adhesi-
ves
• Rotate the light guide into the desired position for
polymerization.
• A barrier sleeve may be used. Note that sleeve can
impact power and irradiance of a curing light. It is
critical to ensure the sleeve is powder free and the
seam is not over the tip of the light guide and that the
sleeve fits well. Intermediate level disinfection (ma-
nual disinfection with ready-to-use disinfectant wipes)
is indicated when a sleeve is used, otherwise the light
guide should undergo high level disinfection (manual
disinfection using disinfectant bath, see "Reproces-
sing the Light Guide").
