Presentation Description/Abstract: The frustration and difficulties related with the removal of separated instruments are well known. The presented file retrieval technique has the approach to be as minimal invasive as possible and more predictable in terms of time management, costs and outcome.
A new troughing technique using sonic instead of ultrasonic reduces the time needed to expose the fractured instrument and minimizes the risk of a second fracture of the instrument as well as heat induced tissue damage.
A specially developed wire with higher tensile strength and reduced elongation as well as a new ball bearing tensioning mechanism allows to remove even ingrained files using a strict push and pull movement.
The device and technique will be described in detail and a step by step tutorial will be presented during this lecture. Several cases will be shown to show the possibilities of this file retrieval technique.

Learning Objectives:

  • Evaluate the risks and benefits of the retrieval of broken files.
  • Discuss the advantages of the presented technique.
  • Evaluate the clinical use of the presented modifications in the lasso technique.
