This advanced microsurgical workshop introduces clinicians to the bone window technique—an innovative and biologically respectful approach to apical surgery. Designed to enhance healing and preserve cortical bone integrity, this method represents a significant evolution in modern endodontic microsurgery.

Participants will learn step-by-step protocols for precise bone window creation, atraumatic handling, and repositioning, all performed under magnification. Drs. Kim and Kratchman will demonstrate how this technique improves surgical access, visibility, and postoperative outcomes.

The course integrates microsurgical principles, flap design, root-end management, and the use of contemporary biomaterials. Through hands-on training, attendees will develop the skills necessary to perform predictable, minimally invasive apical surgery with improved clinical success and patient-centered outcomes.

Instrument separation remains one of the most challenging complications in endodontic treatment. This intensive workshop provides a structured and practical approach to managing fractured files, focusing on when, why, and how to attempt retrieval safely and effectively.

Participants will explore the full decision-making spectrum—from bypassing to removal—based on canal anatomy, fragment location, and risk assessment. Frank Sterzer will demonstrate modern retrieval techniques using ultrasonic systems, and enhanced visualization under magnification.

The hands-on component allows clinicians to practice retrieval protocols in realistic scenarios, improving precision, confidence, and clinical judgment. Emphasis is placed not only on technical execution but also on preventing instrument separation and minimizing iatrogenic damage.

By the end of the session, participants will be equipped with a clear, evidence-based framework for managing one of endodontics’ most stressful complications.
