Operation
Disinfect or autoclave contaminated surfaces of the curing
light as well as light probes and anti-glare cones before
each use.
Furthermore, make sure that the stipulated light intensity
permits adequate polymerization. For this purpose, check
the light probe for contamination and damage as well as
the light intensity at regular intervals (e.g. with the Ivoclar
Vivadent radiometer “Bluephase Meter”).
Selecting the curing program and the curing time
The curing program and the curing time can be individually
set. Bluephase 20i is equipped with the following 4 curing
programs for the different indications. The desired curing
program is selected with the program selection buttons.
The display changes accordingly (see Indicators on the
handpiece). The device comes equipped with the following
preset programs:
Factory settings
TURBO 5 seconds
HIGH
10 seconds
(High Power)
LOW
10 seconds
(Low Power)
SOFT
15 seconds
(Soft start)
The intended curing time is selected
using the time selection buttons.
Users may choose between 5, 10, 15,
20 and 30 seconds.
Observe the Instructions for Use of the material applied
when selecting the curing time.
The curing recommendations for composite materials apply
to all shades and, if not mentioned otherwise in the Instruc-
tions for Use, to a maximum layer thickness of 2 mm. Gen-
erally, these recommendations apply to situations where
the emission window of the light probe is placed directly
over the material to be polymerized. Increasing the distance
between the light source and the material will require the
curing time to be extended accordingly. For instance, if the
distance to the material is 8 mm, the effective light output
is reduced by approx. 50%. In this case, the recommended
curing time has to be doubled.
1) The information provided herein applies to the light
probe 10>8 mm supplied in the delivery form.
2) The information regarding heat development and burn
hazard must be taken into consideration (see Safety
notes).
