Apical fragment ejectors” are specialized dental instruments used in endodontic procedures, specifically during the removal of fractured or broken root canal instruments or fragments from the apical (tip) portion of the root canal.
In endodontic treatment, it’s not uncommon for instruments such as files or reamers to break within the root canal, particularly in cases of complex anatomy, calcified canals, or previous root canal treatment. When this occurs, it’s essential to remove the fragment to ensure successful completion of the root canal therapy and prevent complications such as infection or obstruction.
Apical fragment ejectors are designed to safely grasp and remove these broken fragments from the root canal. They typically consist of a slender, flexible shaft with a specialized tip or claw-like mechanism that can engage and securely grasp the fragment. Once the fragment is firmly held, the ejector allows for controlled retrieval of the fragment from the canal.
These instruments may come in various sizes and designs to accommodate different canal shapes and sizes. Additionally, some apical fragment ejectors may incorporate features such as adjustable grips or angulated tips to enhance maneuverability and facilitate access to difficult-to-reach areas within the root canal system.
