Micro Mega Hero Shaper Classic Rotary Assorted

Description

Using HERO Shaper for orthograde treatment has never been quicker and simpler. Conditions such as irreversible pulp pathology, pulpitis and necrosis are easily managed using the HERO Shaper® rotary nickel -titanium instruments at low speed.

HERO Shaper files, with their pronounced tapers, are designed for use with the crown-down technique to progressively remove constraints and flare the canal. The coronal third is prepared using .06 taper HERO Shaper files and the apical third is prepared using .04 taper HERO Shaper files. The varying helical pitch and length of the cutting portion of the files provide them with an excellent combination of efficiency and flexibility.

Yellow sequence

Difficult canals, severely curved, possibly with significant hypercalcification, making any first penetration tricky with the finest hand files. Speed 300 to 600 rpm

Red sequence

Canals of average difficulty with moderate curvature and/or more hypercalcification, making first penetration with a No.10 K file harde to achieve. Speed 300 to 600 rpm

Blue sequence

Easy canal preparation, low curvature, orifice and canal large enough to allow a No.15 K file to reach the Apex. Speed 300 to 600 rpm

Key Features

• Avoids screwing effects: the helical angle of the cutting edges varies from the tip to the shank.
• The new pitch also varies according to the taper: the more tapered an instrument is, the longer is its pitch
• The blade shows a triple helix cutting edge.
• The tip is inactive in order to follow the canal anatomy.
• Improved patient comfort.
• Time saving : 10 seconds of use per instrument for efficient shaping.
• Reduced operator fatigue.
• Less instruments to handle.
• Reproducible results.

Directions for Use

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.
