RETREATY – Endodontics Kit

RETREATY – Endodontics Retreatment Kit

RETREATY is a specialized endodontic retreatment kit designed to address the growing demand for predictable, efficient, and minimally invasive root canal retreatment procedures. As retreatment therapies continue to increase compared to primary treatments, RETREATY was developed to enable precise endodontic disassembly while preserving the natural anatomy of the root canal system—following the principles of minimally invasive endodontics inspired by modern clinical philosophies.

The kit is engineered for non-surgical retreatment, allowing effective removal of gutta-percha obturation material without the use of solvents, improving safety, speed, and clinical control.

🔬 Kit Composition & Instrument Design

RETREATY includes a carefully sequenced set of rotary files, each designed for a specific phase of retreatment:

BULL – Coronal Gutta-Percha Remover

• Size: #25 / .07

• Specifically designed for coronal gutta-percha removal

• Gold heat-treated alloy, short file length, and optimized tip design

• Enables fast removal of obturation material without solvents

• Ideal for initial retreatment access during non-surgical procedures

SKINNY – Mid-Apical Debris Remover

• Size: #25 / .04

• Thin yet powerful design for controlled debris removal

• Silver-colored file used in the middle and apical thirds

• Preserves original canal anatomy

• Creates a reproducible pathway close to the apical terminus

SHAPY Series – Final Canal Shaping Files

SHAPY 1

• Size: #20 / .05

• Designed for deep shaping after patency is achieved

• Gold alloy provides excellent flexibility and unwinding resistance

• Establishes the initial final shaping form

SHAPY 2

• Size: #25 / .05

• First true shaper following patency

• Flexible gold alloy with high cutting efficiency

• Designed to follow the natural canal anatomy

SHAPY 3

• Size: #30 / .05

• Blue alloy for increased flexibility

• Optimized for apical shape enlargement

• Ensures maximum adaptation without altering the original canal path

⚙️ Operating Parameters

• Speed Range: 350–500 RPM

• Torque: 1.5 N·cm

• Cross Section: Optimized for retreatment efficiency

These parameters ensure controlled cutting action, reduced instrument stress, and safe retreatment performance.

🧭 Step-by-Step Instructions for Use

1. Review multiple horizontally angulated radiographs to assess root width, length, curvature, and canal anatomy.

2. Prepare coronal access to clearly identify each canal orifice.

3. Use BULL at the orifice level in clockwise or reciprocating motion to remove gutta-percha from the coronal third.

4. Introduce SKINNY in the middle third, advancing 1–3 mm with gentle in-and-out motion to remove remaining obturation material.

5. Use a K-file to electronically measure working length and establish patency passively.

6. Perform final shaping by sequentially using SHAPY 1, SHAPY 2, and SHAPY 3, adjusting the final canal size as required.
