Removing Fiber Posts
Post removal with safety and predictability.
Due to the growing demand of cosmetic interventions in the dental practice, new metal free retention systems have been developed. These fiber posts are similar to natural teeth in color. However, when retreatment is inevitable, removing non metal posts can be an obstacle to performing a new endodontic intervention. The use of ultrasonic tips to remove fiber posts can considerably reduce the treatment duration and avoid common mistakes related to this procedure.
Step-by-Step Fiber Post Removal
1 – Remove the crown using a high speed turbine with a regular bur;
2 – Isolate the treatment area with a rubber dam;
3 – Abrade the resin core using a high speed turbine with a diamond bur;
4 – Abrade the post inside the canal using a high speed turbine with a long round diamond bur;
5 – Using a diamond coated ultrasonic tip, typically the E3D or the E6D, abrade the remainder of the fiber post, keeping the power setting between 30% and 40%;
6 – During the procedure, keep the instruments in the same angle as the post;
7 – After locating the root canal or the restorative material, remove the Gutta-Percha and shape the canal with the appropriate rotary instruments.
1. Reduce the coronal portion.
2. Fiber post inside the resin cement.
3. Reduce the post inside the canal using a round bur.
4. Reduce the remaining of the fiber post using a diamond coated ultrasonic tip.
