Protocol |
Yellow Sequence |
| |
|
|
Difficult canals, severely curved, possibly with significant hypercalcification, making any first penetration tricky with the finest hand files. |
---------------------------------------------------------------------------------------------------------------------------- |
| |
| Red Sequence |
| |
|
| |
Canals of average difficulty with moderate curvature and/or more hypercalcification, making first penetration with a n°10 K file harde to achieve. |
| |
---------------------------------------------------------------------------------------------------------------------------- |
| |
| Blue Sequence |
| |
|
| |
Easy canal preparation, low curvature, orifice and canal large enough to allow a n°15 K file to reach the Apex. |
| |
---------------------------------------------------------------------------------------------------------------------------- |
| |
| Rotation speed: |
| The rotation speed must be 300 to 600 rpm. |
| |
| First penetration: |
|
The first penetration is performed with a conventional hand instrument (usually a n°10 K file-MMC n°10/21 mm). This is used to confirm the working length (WL), canal anatomy and diagnosis from the pre-operative X-ray. |
|
- |
Canal mineralisation and curvature will determine the treatment difficulty and thus the most suitable instrumentation sequence for the clinical case. |
| |
|
|
|
| Penetration levels: |
- |
.06 taper files are brought to 2/3 of the working length. 04 taper files are brought to WL.
An accurate determination of the working length between the passage of the .06 and .04 file is strongly recommended. |
|
| |
|
|
| Operating procedure: |
|
- |
HERO Shaper® is positioned at the canal entrance. The motor is started and maintained at constant speed whilst the file is working and until it is completely withdrawn from the canal. |
|
- |
The file is inserted to the desired working length with a short in and out movement using light pressure. |
- |
HERO Shaper® also allows circumferential filing to be achieved which permits the canal anatomy to be taken into account and in particular to shape lateral zones. |
| |
|
|
| Irrigation: |
|
It is important to thoroughly irrigate the canal between the passage of successive instruments. |
