This study compares the fracture resistance of endodontically treated teeth restored with different fiber posts. Customized glass fiber posts and SFRC-relined fiber posts show promising biomechanical efficiency for dental restorations.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Restorative Dentistry
Background:
- Endodontically treated teeth have reduced fracture resistance due to structural loss.
- Fiber posts are used to restore these teeth, but their comparative efficacy is unclear.
- Short fiber-reinforced composite (SFRC) can improve fiber post adaptation.
Purpose of the Study:
- To compare the fracture resistance of endodontically treated teeth restored with prefabricated carbon fiber posts, customized glass fiber posts, and SFRC-relined fiber posts.
Main Methods:
- 30 extracted single-rooted human teeth underwent endodontic treatment and post space preparation.
- Teeth were randomly assigned to three groups: prefabricated carbon fiber posts, customized glass fiber posts, or SFRC-relined fiber posts.
- Specimens were restored and tested for fracture resistance using a universal testing machine with a compressive load.
Main Results:
- Data collection and analysis are scheduled for completion by May 2026.
- No specimens have been tested as of April 2025.
Conclusions:
- The study is expected to provide comparative biomechanical evidence on fiber post systems.
- Findings may assist clinicians in choosing optimal restorative strategies for endodontically treated teeth.
