Removing Threaded Posts
Remove posts in a fast, efficient and safe way
During endodontic retreatment, the removal of a threaded metal post can be a difficult procedure which carries the risk of perforation and fracture of the tooth. Ultrasonic vibration breaks the bond between the post and the canal walls, facilitating its removal. There are many advantages of using ultrasonics for this procedure, including speed, conservation of tooth structure, and minimizing risk of tooth fracture.
Step-by-Step Threaded Posts Removal
1 – Using a transmetal or diamond bur, abrade the coronary portion of the post until the cement line is visible (high speed turbine with water cooling).
2 – After the cement line is visible, use the E8 ultrasonic tip (60% power and water cooling on) to break/remove the cement around the metal post.
3 – Next, place the E9 ultrasonic tip sidewards to the post and apply a counterclockwise vibration (70% power and water cooling on) in order to brake the cement and pull out the post.
1. Reduce the coronal portion.
2. Exposed Threaded Post.
3. Counterclockwise vibration with sidewards placed E9 insert.
4. Repeat step 3 until the post is removed.

“Since I started to use Helse ultrasonic tips, it was clear to me that I was dealing with innovative and excellent products for Endodontics. Cost wise they are a great deal, and the clinical results are outstanding.”
