R-Motion®
Thinner core and optimized tip for lower dentine stress with enhanced cyclic fatigue resistance (manufacturer data)
| File | Tip | Taper | Motion |
|---|---|---|---|
| R-Motion Glider | 0.15 | 3% variable (3% first 9mm then 6%) | Reciprocating |
| R-Motion Glider C | 0.15 | 3% variable | Reciprocating |
| R-Motion 20 | 0.20 | 4% | Reciprocating |
| R-Motion 25 | 0.25 | 6% | Reciprocating |
| R-Motion 30 | 0.30 | 4% | Reciprocating |
| R-Motion 40 | 0.40 | 4% | Reciprocating |
| R-Motion 50 | 0.50 | 4% | Reciprocating |
Most cases require only 2 instruments: Glider + one shaping file
Compatible with any endo motor offering reciprocating counterclockwise mode
FKG Rooter X3000/X4000 has auto-preset for R-Motion (F: auto, R: auto in REC mode)
Manufacturer reports improved cyclic fatigue resistance, flexibility, and reduced dentine stress vs standard reciprocating systems (internal lab data — exact figures not independently verified from accessible primary sources)
Heat-treated NiTi allows pre-bending for curved canal access
Electrochemical polishing provides smooth surface finish
Rounded triangular cross-section optimizes cutting efficiency and debris removal
Thinner core design reduces dentine stress during instrumentation
Obturation Techniques
Single cone, warm vertical, carrier-based & lateral compaction
