  • Isolate the operating field with rubber dam
  • Ensure proper access cavity preparation

Instrument Preparation:

  • Select appropriate cannula size based on canal diameter
  • Choose suitable retrieval file length
  • Clean and sterilize all reusable components

6. Setup (Assembly)

Step 2: Assembly

  1. Attach the selected cannula to the universal adapter handle.
  2. Insert the retrieval file through the cannula.
  3. Ensure smooth movement of the file within the cannula.

7. Operating Procedure

Step 1: Assessment and Selection

  1. Confirm the location and length of the separated instrument using radiographs.
  2. Select the appropriate cannula size (should fit passively into the canal).
  3. Choose the correct retrieval file length.

Step 3: Insertion

  1. Gently insert the cannula into the root canal.
  2. Advance until the tip is just short of the separated instrument.
  3. Maintain a straight line of access.

Step 4: Engagement

  1. Advance the retrieval file through the cannula.
  2. Engage the file with the separated instrument using a clockwise rotation.
  3. Apply gentle pressure to ensure secure engagement.

Step 5: Retrieval

  1. Carefully withdraw the entire system (cannula + retrieval file + separated instrument).
  2. Maintain steady pressure and avoid sudden movements.
  3. If resistance is encountered, reassess the engagement.

8. User Tips for Success

For Different Instrument Types:

  • For Files: Engage in the flutes using clockwise rotation.
  • For Posts: Use the tip of the retrieval file to engage the post.
  • For Screws: Engage the threads carefully to avoid further separation.

For Challenging Cases:

  • Use sodium hypochlorite irrigation to lubricate the canal.
  • Consider using ultrasonic activation for better engagement.
  • In severely curved canals, consider alternative approaches.
