Normal Operation; Direct Restorative Mode - Loop Clk01 Gebrauchsanweisung

4.2 NORMAL OPERATION

Loop has two operational modes for curing dental materials: Direct Restorative and Tack.
™
Direct Restorative is the default mode, and it can be used with the closed-loop either ON or OFF. See sections 4.1.2
and 4.1.3 for instructions on these features.
Tack is used to deliver a short burst of light (1,000 mW/cm
adhesives. After completing a tack cycle, the handpiece immediately returns to the last-used Direct Restorative Idle
screen.
NOTE: For curing bleached shades (e.g. bleached shade M1) and extra light surfaces, it is recommended to touch
the lens directly on the surface immediately after the top layer is hardened. This allows the unit to recognize a
bleached shade and adjust the delivered energy accordingly.

4.2.1 Direct Restorative Mode

Refer to sections 4.2.2 and 4.2.3 for information on curing with closed-loop ON or OFF
Direct Restorative mode can be operated in cycle times of 3, 5, 10, 15 or 20 seconds (depending on the selected
irradiance). The factory preset time is 20 seconds. To change the time setting, press the Select button. See the dental
material manufacturer's Instructions for Use when selecting the cure time.
The Direct Restorative mode can be operated with irradiance levels of 1,000, 2,000, or 3,000 mW/cm
preset irradiance level is 1,000 mW/cm
There are two commonly used settings that can be quickly accessed by pressing and holding the Select button.
Press and hold the Select button to quickly jump between two available preset irradiance and duration presets.
Preset 1: 20 seconds, 1,000 mW/cm
Direct Restorative mode recommended technique:
1. Set the cure duration longer for deeper fillings, darker shades, or for specific materials.
2. Press the Start/Stop button to initiate the cure cycle.
3. Position the lens of the handpiece within 3 to 4mm of the center of the targeted surface
during the cure cycle.
4. When closed-loop is ON, if the lens is positioned too far away, it will enter AutoStart (refer to Section 4.1.3 "Curing
with Closed-Loop ON"). In this situation, move the lens closer to the surface (3 to 4mm) allowing the cure cycle to
automatically start.
5. When closed-loop is ON, once the cure cycle is in process, Loop™ will actively adjust irradiance at the targeted
surface regardless of the distance from the target until the maximum distance (approximately 8 to 10mm) is
exceeded or the lens is moved over the gingiva.
6. Once the surface of the material is hardened, resting the lens directly on the surface ensures the most accurate
cure.
NOTE:
• When closed-loop is ON if the lens is moved too far from the tooth or onto other tissues, Loop
Auto Start and automatically pause until returned to proper position over a tooth surface. Auto Start will
be on for a limited time before canceling.
• During a cure, if any button is pressed, the cure cycle will be cancelled, and the handpiece will return to the
Idle screen.
• If the restoration area is greater than 6mm across, the operator can pull the lens away from the tooth for
more surface coverage. This may initiate an automatic addition of time to the cure cycle.
Refer to Section 2 "Safety" for details on safety.
