Stress-Reduced Restoration of Endodontically Treated Teeth Using Fiber-Reinforced Direct Composite Resin: A Case Series

Abstract

Background: Restoration of badly broken endodontically treated teeth (ETT) presents a significant challenge in dentistry. Traditional approaches typically involve posts, crowns, or indirect restorations. However, the use of fiber-reinforced composite resin (FRC) for direct restorations has gained traction due to its ability to provide structural support while maintaining a more conservative treatment approach. Objective: This case series aims to demonstrate the effectiveness of stress-reduced direct composite restorations using the "wallpapering technique" as an alternative to full-coverage indirect restorations, particularly in young patients under 18 years of age. Case Presentation: Three cases involving the restoration of anterior and posterior ETT were performed using a combination of continuous glass fiber (Interlig, Angelus), discontinuous short fiber-reinforced composite (EverX Posterior, GC), and nanohybrid composite resin (Tetric N Ceram, Ivoclar). These cases are still under follow up and the outcome after six months is presented in this report. Conclusion: The wallpapering technique, combined with FRC materials, provides a reliable and conservative approach for restoring badly broken ETT. It offers a functional, esthetic, and durable solution, particularly for patients who are not yet candidates for full-coverage restorations.
