Shape coronally with SX
Use SX to improve coronal access and reduce early resistance before middle-third shaping. Irrigate thoroughly after the file is withdrawn.
SX300 RPM3.0 NcmPT Technique
TransformX™ PT is designed for clinicians who prefer a progressive taper workflow. The sequence supports coronal shaping, controlled middle-third preparation, and selected apical finishing while preserving the principles of irrigation and patency.
Clinical Problem
Section titled “Clinical Problem”Progressive Taper Control
Progressive taper systems can prepare efficiently, but they require disciplined staging. If the coronal and middle thirds are not managed clearly, apical files may carry unnecessary load.
The PT technique works best when each file has a defined purpose: coronal shaping, middle-third preparation, and apical finishing only after irrigation and recapitulation confirm that the canal remains negotiable.
Clinical Risks & Consequences
Section titled “Clinical Risks & Consequences”| Risk factor | Clinical consequence |
|---|---|
| Rushing coronal shapingInsufficient early enlargement | More resistance as files progress toward working length |
| Skipping recapitulationPatency not reconfirmed between files | Debris packing, ledging, or loss of working length |
| Over-selecting final file sizeApical finishing not matched to anatomy | Unnecessary dentin removal or apical transportation |
| Excessive apical pressureFile pushed beyond canal response | Higher torsional stress and reduced procedural control |
TransformX™ Solution
Section titled “TransformX™ Solution”The PT workflow uses a progressive sequence to create space coronally, then shape toward working length with repeated irrigation checks before final apical selection.

Prepare the middle third
Use S1 and S2 in sequence, irrigating and recapitulating between files so the canal remains open and the file is not asked to push through packed debris.
S1S23
Finish apically by anatomy
Select F1, F2, or F3 according to apical anatomy and clinical indication. Use controlled advancement and stop when the preparation objective has been reached.
F1 / F2 / F3Key Features
Section titled “Key Features”Progressive Sequence
Each file prepares the pathway for the next stage, reducing abrupt engagement during apical progression.
Avatar Tip Guidance
Tip geometry supports centred preparation and controlled termination as the sequence reaches the apical third.
Familiar Motor Settings
300 RPM and 3.0 Ncm give a simple reference point for clinicians using progressive taper workflows.
Clinical Benefits
Section titled “Clinical Benefits”Clear file purpose from coronal shaping to apical finishing.
Reduced risk of packing debris ahead of the sequence.
Improved control when choosing final apical file size.
A familiar progressive taper pathway for PT-style clinicians.
Where It Fits
Section titled “Where It Fits”Use the PT technique when the clinician wants a progressive taper approach with familiar handling and a clearly staged route from coronal shaping to apical finishing.
