Removing metallic obstructions during endodontic retreatment can be challenging, especially with fractured instruments. Specialized devices offer successful management for fractured instruments, dowel posts, and silver cones, improving retreatment outcomes.

Area of Science:

  • Endodontics
  • Dental Materials Science

Background:

  • Metallic obstructions, including fractured instruments, posts, and silver cones, present significant challenges in endodontic retreatment.
  • Failure to remove these obstructions can compromise the success of retreatment procedures.

Purpose of the Study:

  • To critically review devices and techniques for the removal of metallic obstructions during endodontic retreatment.
  • To evaluate the success rates and challenges associated with removing various types of metallic obstructions.

Main Methods:

  • Review of literature on specialized devices such as the Masserannkit, Canal-Finder-System, and ultrasonic systems.
  • Analysis of techniques for removing fractured instruments, root posts, and silver cones.

Main Results:
