PT Technique Guide

This guide is for clinicians using the PT TransformX system, designed for those experienced with ProTaper Gold or ProTaper Next systems.

Prerequisites

• Established access cavity
• Working length determined
• Glide path confirmed to working length

Motor Settings

Step	File	Speed	Torque	Purpose
1	SX	300 RPM	3.0 Ncm	Coronal Shaping
2	S1, S2	300 RPM	3.0 Ncm	Middle Third Shaping
3	F1, F2, F3	300 RPM	3.0 Ncm	Apical Finishing

Step-by-Step Sequence

Step 1: Coronal Shaping

• Use SX at 300 RPM, 3.0 Ncm
• Create initial coronal flare
• Establish straight-line access to the mid-root
• Irrigate thoroughly

Step 2: Middle Third Shaping

• Use S1 at 300 RPM, 3.0 Ncm — shape to resistance
• Irrigate → Recapitulate → Re-irrigate
• Use S2 at 300 RPM, 3.0 Ncm — shape to working length
• Irrigate → Recapitulate → Re-irrigate

Step 3: Apical Finishing

• Use F1 at 300 RPM, 3.0 Ncm — to working length
• Select F2 or F3 based on apical anatomy
• Complete apical sizing

Key Points

1. Always irrigate between files
2. Recapitulate with a small hand file after each rotary
3. Re-irrigate before proceeding to the next file
4. Confirm patency throughout the procedure
5. Follow the progressive philosophy — each file prepares for the next

Avatar™ Tip Advantage

The Avatar tip design allows the file to:

• Follow the progressive shaping philosophy with enhanced control
• Maintain centred preparation through curvatures
• Reduce the risk of transportation
• Support controlled termination in the optimal apical zone

File Selection Guide

File	Tip Size	Taper	Use Case
SX	19	Progressive	Coronal flaring
S1	17	Progressive	Initial shaping
S2	20	Progressive	Full-length shaping
F1	20	.07	Small canals
F2	25	.08	Medium canals
F3	30	.09	Larger canals
