Great Taper: Recommended use

GT instruments are used in a rotating contra-angle with a high torque and a constant speed of (150-) 350 rpm, while employing light pressure. Each instrument is used for 5 to 10 seconds in a pecking motion: push forward - draw back - push forward etc. If the instrument does not proceed in the canal, pressure must not be increased but a smaller instrument must be tried.

Preparation is based on a crown-down technique where the coronal and mid-part of the canal are prepared with four crown-down instruments before apical preparation. Preparation is finished by coronal flaring, using one or more of the three flaring instruments. Always refer to the manufacturer's latest instructions and recommendations on the correct use of the instruments.
