Technique for post-core removal from a crown and a new post-core fabrication

Area of Science:

• Restorative Dentistry
• Prosthodontics
• Dental Materials

Background:

• Post-and-core restorations are common in endodontically treated teeth.
• Cemented posts can be challenging to remove without damaging the crown.
• Restoration failure may necessitate replacement, impacting cost and patient treatment.

Purpose of the Study:

• To present a method for removing cemented posts while preserving the integrity of the crown.
• To describe the process of fabricating a replacement post-core assembly.
• To demonstrate the feasibility of reusing the original crown after post removal.

Main Methods:

• A technique for the non-destructive removal of cemented posts from crowns was developed.
• A new post-core assembly was fabricated to fit the prepared canal space.
• The original crown was prepared and cemented onto the new post-core assembly.

Main Results:

• Successful removal of cemented posts was achieved without compromising the crown.
• The fabrication of a custom replacement post-core assembly was demonstrated.
• The original crown was effectively reused, maintaining its fit and aesthetics.

Conclusions:

• This method offers a viable approach for salvaging crowns with failed or problematic post-core restorations.
• It provides a cost-effective and conservative alternative to complete crown replacement.
• The technique facilitates the preservation of natural tooth structure and existing restorations.
