Purpose/Objectives: To present recent updates in technology and techniques in post removal.

Review: Post removal is usually indicated in 3 situations – failing endodontic treatment, teeth are non-restorable without post removal, or improvement of design, mechanics, or aesthetics of a new restoration. The following are the author’s recommendations. Preoperative – Two or three well angled radiographs; knowledge, respect and appreciation of tooth anatomy; knowledge of different post types (parallel, tapered, and threaded) Techniques – Remove all circumferential restorative material; use of piezoelectric ultrasonic is encouraged for this; the post removal system (PRS) is used to dome, thread and extract the post. The PRS has the advantage of removing non-threaded posts with the extractor pliers and removing threaded post because of it CCW threading design.

Author’s Conclusion: These instruments and techniques make post removal more predictable and simple.

Reviewer’s Comments: A good review of post removal basics.
