OneStep® - Root Filling System

A safe and effective root filling system with natural gutta-percha - the gold standard for root canal filling for over 100 years.

Why use a OneStep® obturator?

OneStep® is the second generation of obturators from CMS Dental, developed for better working area and space during treatment - without a handle. The radiopaque plastic core (ISO #20 - 60) is surrounded by natural thermoplastic gutta-percha and works with both traditional hand files and all rotary file systems.

Technique overview

The obturator consists of a rigid core (carrier) uniformly coated with gutta-percha. Once heated, the gutta-percha becomes flowable while the carrier provides control and guidance during placement.

1. Select the Obturator - Choose a size matching the final shaping instrument and verify fit using a verifier.
2. Apply Sealer - Coat the canal walls lightly with endodontic sealer.
3. Heat the Obturator - Place the carrier in the designated oven until gutta-percha reaches optimal thermoplastic consistency.
4. Insert to Working Length - Deliver the obturator smoothly to full working length in one continuous motion.
5. Remove Handle & Condense - Cut the carrier at the orifice level and apply light vertical pressure to adapt the material coronally.

Key clinical advantages

Clinical considerations

• Ensure accurate working length and canal preparation before obturation.
• Avoid excessive sealer - gutta-percha provides the bulk of the fill.
• Use steady, controlled insertion to prevent stripping gutta-percha from the carrier.
