TS4

TS4 – Rotary Endodontic File System

TS4 is a high-performance NiTi rotary endodontic file system engineered to deliver safe, flexible, and highly efficient root canal preparation. Developed using a specialized heat-treatment process, TS4 features a unique W-shaped cross-section that significantly reduces dentinal stress while enhancing elasticity, cutting efficiency, and resistance to cyclic fatigue.

Designed for clinicians who demand precision and adaptability, TS4 allows controlled canal shaping while preserving dentin integrity and respecting the natural canal anatomy.

🔬 Design Philosophy & Clinical Benefits

W-Shaped Cross Section

The distinctive W-shaped design, achieved through advanced heat treatment, minimizes contact stress on canal walls. This reduces the likelihood of micro-crack formation in dentin and improves safety during high-speed rotary instrumentation.

Enhanced Flexibility & Elasticity

TS4 exhibits outstanding flexibility and elasticity, allowing smooth navigation through curved canals while maintaining stable cutting performance even at higher rotational speeds.

Efficient Debris Management

With a smaller cross-sectional profile, especially at minimal taper levels, TS4 prevents excessive debris accumulation inside the canal, improving cleanliness and reducing procedural complications.

⚙️ File Sizes, Torque & Speed Parameters

TS4 offers multiple file configurations to address different clinical needs:

This range allows progressive shaping from glide path development to final canal enlargement.

🧠 Advanced Shaping Capability

• With a minimal 0.01 taper design, TS4 enables precise control and reduced canal stress.

• Through repeated controlled motion and extended instrumentation time, tapers of up to .08 can be achieved, allowing excellent adaptation to complex canal morphologies.

• Maintains canal centering while adapting naturally to canal shape.
