What it covers
This lecture focuses on the complex challenge of removing non-visible broken instruments located beyond severe canal curvatures, exceeding 30 degrees. Dr. Terauchi presents advanced ultrasonic instrumentation strategies specifically developed to navigate and access fractured files in anatomically demanding situations.
Two preparation techniques are compared—180-degree and 90-degree approaches—detailing the scenarios in which each method offers optimal visibility and access. The lecture outlines critical steps for conservative dentin removal, tip positioning, and the precise manipulation of ultrasonic energy to safely dislodge fragments embedded deep within curved canals.
By mastering these advanced techniques, clinicians can significantly improve their success rate in fractured instrument retrieval while preserving tooth structure and minimizing iatrogenic damage.
In particular, this lecture covers the following topics:
- 180° vs. 90° canal preparation techniques for fractured file access
- Strategic removal of broken files beyond severe (>30°) canal curves
- Step-by-step application of ultrasonic tips in curved canal anatomy
- Clinical tips to optimize visualization, access, and dentin preservation
