Endodontic Retreatment: From Complex Anatomy to Instrument Retrieval. Antonis Chaniotis Hands-On Workshop

Orthograde endodontic retreatment requires not only an in-depth understanding of root canal anatomy but also proficiency in specialised techniques for managing complex clinical situations.

This course focuses on a systematic approach to endodontic retreatment, from assessing the causes of persistent apical periodontitis and controlling intracanal infection to addressing the technical challenges encountered during retreatment.

What you will learn:

— Plan retreatment: Identify the causes of primary treatment failure and select an appropriate retreatment strategy.

— Negotiate complex canals: Locate and negotiate calcified and hidden canals, including MB2, and manage canals with severe curvature.

— Remove filling materials and posts: Explore techniques for removing different root canal filling materials and intracanal posts.

— Overcome iatrogenic obstacles: Bypass canal ledges, manage false canals and navigate complex root canal anatomy.

— Retrieve separated instruments: Learn ultrasonic, loop-based and other techniques for bypassing and retrieving separated instrument fragments.

The hands-on session will allow participants to consolidate their knowledge and practise key technical skills on training models under the instructor’s guidance. Participants will explore different approaches to negotiating complex root canals, re-establishing the original canal pathway, and bypassing or retrieving separated instrument fragments at different levels of the root canal.

2. Management of Calcified Root Canals

— Freehand techniques for locating and negotiating calcified root canals

— Planning and use of surgical guides for the management of calcified root canals.

3. Removal of Root Canal Filling Materials and Posts

— Techniques for removing root canal filling materials

— Removal of cast metal and fibre posts: clinical approaches and technical challenges.

4. Canal Ledges, False Canals and Complex Anatomy

— Bypassing iatrogenic canal ledges and managing false canals

— Management of canal splitting and internal root resorption.

5. Identification and Negotiation of Hidden and Severely Curved Canals

— Identification and negotiation of the second mesiobuccal canal (MB2) and other hidden canals

— Management of S-shaped canals, abrupt canal curvatures and root dilacerations.

6. Management of Separated Endodontic Instruments

— Prevention of instrument separation, with strategies for bypassing and retrieving separated fragments

— Wedging techniques, ultrasonic techniques, the tube-and-glue technique and loop techniques

— Management of separated instrument fragments in the coronal, middle and apical thirds of the root canal.
