ProTaper Ultimate™
Slider-Shaper-Finishers concept with dual heat treatments: Gold for standard sequence, Blue for auxiliary finishers in large canals

Slider-first glide path: Slider can often be used without prior K-file (67% of cases per Dentsply user study). If Slider does not easily reach terminus, use a small SS hand file first, establish WL/patency, then retry Slider (per IFU)
Only one Shaper needed for coronal 2/3 enlargement
Triple heat treatment: M-Wire (Slider), Gold (Shaper/F1-F3), Blue (FX/FXL)
Blue heat treatment on FX/FXL: dedicated for large straight canals
Manufacturer reports 32% faster glide path and shaping vs ProGlider + PTG up to F2 (product page bench data, not independent clinical validation)
Manufacturer reports F1: +13% flexibility, +75% cyclic fatigue resistance vs PTG F1 (fact file bench data)
Manufacturer reports F2: +30% flexibility, +30% cyclic fatigue resistance vs PTG F2 (fact file bench data)
Manufacturer reports higher unwinding resistance vs previous generations (fact file bench data; Diaconu 2024 supports improved cyclic fatigue vs PTG F2 in vitro, PMID 38667542)
Use outward brushing motion away from furcation in irregular canals, or light inward pecking to advance
Dedicated hand-use version available for all PTU files with same technical features
Compatible with ProTaper Ultimate Conform Fit GP points and absorbent points
For extremely curved canals: use single canal per file and consider manual files in apical region (per IFU)
Obturation Techniques
Single cone, warm vertical, carrier-based & lateral compaction
