Polyvision - Automatic assistant with intelligent anti-glare protection
Bluephase PowerCure features a fully automated "polyvision" assistant for safe polymerization.
This feature enables the curing light to automatically sense if the handpiece is inadvertently
moved from its position during the curing procedure. To prevent any associated reduction in the
amount of energy being transferred, the device will start to vibrate to alert the user to the
improper use and will automatically extend the curing time by 10%. If the handpiece is significantly shifted away
from its initial position (e.g. out of the oral cavity), the light will automatically switch off so that the curing process
can be restarted and carried out correctly.
In addition, polyvision also acts as intelligent anti-glare protection. Polyvision ensures that the curing light cannot be
used outside the mouth. The light can only be activated once the light guide is positioned directly over the material
to be polymerized. This protects the operator and patient from being blinded by the light.
If a protective sleeve is used, this function is not available. Contamination of the light guide may affect the
functionalities of the polyvision assistant. T he automatic assistant is there to support the user. It does not obviate
the need for monitoring by the user. If you do not want to use the assistant, you can deactivate it at any time by long
pressing (> 2 seconds) the Time or Program selection button. The symbol on the handpiece (see 3. 1 Indicators on the
handpiece) then disappears.
Measuring the light intensity
We recommend checking the light intensity emitted by the curing light at regular intervals using the integrated
radiometer in order to be sure that the materials are adequately cured and the composite fillings are of a high and
lasting quality (see 3. 1 Start-Up).
Cure Memory function
The last settings used, together with the combination of curing program and curing time, are automatically saved.
Start/Stop
The light is switched on by means of the Start/Stop button. It is recommended that the emission window of the light
guide is placed directly on the material to be polymerized. Once the selected curing time has elapsed, the curing
program is automatically terminated. If desired, the light can be switched off before the set curing time has elapsed
by pressing the Start/Stop button again.
Acoustic signals
Acoustic signals can be heard for the following functions:
– Start (Stop)
– Every 10 seconds
– Curing time and program change
– Insert battery
– Error message (when anti-glare protection is activated or curing cycle aborted)
– Error message when attempting to activate the 3sCure program during the 30-second waiting time that follows
after the program has been used twice in succession.
Light intensity
The light intensity is maintained at a consistent level during operation. If the supplied 10>9 mm light guide is used,
the light intensity has been calibrated to 1,200 mW/cm
In the Turbo program, the light intensity is calibrated to 2,000 mW/cm
the light intensity is calibrated to 3,000 mW/cm
influences the emitted light intensity.
When focussing light guides (10>9 mm) or Pin-Point light guides (6>2 mm) are used, the diameter of the light entry
is larger than the diameter of the light emission window. The incident blue light is therefore concentrated over a
smaller area. As a result, the emitted light intensity is increased.
Pin-Point light guides are suitable for spot-on polymerization, e.g. to tack veneers in place before removing excess
material. For complete polymerization, the light guide must be changed.
