Removing Cast Posts

Ultrasonics allow you to remove cast posts in a fast, efficient and safe way.

During endodontic retreatment, the removal of a cast metal post can be a difficult procedure which carries 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.

E8

E8 – Scouter

The E8 – Scouter has excellent durability. It is used primarily for uncovering a canal orifice or removing cement from metal posts. 

  Ideal 30% Max 50%

E12

E12 – Post Removal

The E12 is recommended for post removal. 

  Ideal 80% Max 100%

Step-by-Step Cast Post Removal

Protocol 1

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 – In case of monoblock casting, use the bur to split it in two separate posts.

3 – After the cement line is visible, use the E8 ultrasonic tip (30% power and water cooling on) to break/remove the cement around the metal post.

4 – Next, place the E12 ultrasonic tip in the most cervical portion of the post and apply vibration (80% power and water cooling on) in order to brake the cement and pull out the post.

Protocol 2

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 – In case of monoblock casting, use the bur to split it in two separate posts.

3 – After the cement line is visible, use the E8 ultrasonic tip (30% power and water cooling on) to break/remove the cement around the metal post.

4 – Next, use the SIUS technique (Simultaneous and Integrated Ultrasonic System), placing two E12 ultrasonic tips in the most cervical portion of the post – place them opposite to each other – and applying vibration (80% power and water cooling on) in order to brake the cement and pull out the post.

Dr Albert Goerig Quote

“I have Helse dental technology ultrasonic tips since they first came out and have found them highly effective, well-designed, reasonably priced and of excellent quality. I especially love them in my apical surgeries.  I would highly recommend this product.”
