Fiber-Reinforced Composites in Fixed Prosthodontics: A Comprehensive Overview of Their Historical Development, Types, Techniques, and Longevity

Abstract

Background: Fiber-reinforced composites (FRCs) have emerged as transformative materials in restorative dentistry, particularly for managing partial edentulism through fixed partial dentures (FPDs). Their superior aesthetic, mechanical, and adhesive properties offer a minimally invasive alternative to traditional metal–ceramic restorations. Objective: This review aims to evaluate the historical evolution, clinical applications, technological advancements, and prospects of FRCs in prosthodontics, emphasizing their potential to deliver durable, aesthetic, and cost-effective treatment solutions. Methods: This narrative review follows the SANRA guidelines. A comprehensive literature search was conducted across PubMed, ScienceDirect, and Google Scholar for studies published between January 1995 and January 2025. Search terms included “fiber-reinforced composite”, “fixed prosthodontics”, “fixed partial dentures”, “adhesive restorations”, and “implant-supported restorations”. Only English-language studies addressing the clinical applications, mechanical properties, technological innovations, or survival outcomes of FRCs were included. Data were extracted from original research papers, systematic reviews, and narrative reviews. Results: Advancements in fiber architecture, resin matrices, and polymerization techniques have enhanced the strength, aesthetics, and longevity of FRC-based FPDs. Their high flexural strength, fatigue resistance, and compatibility with adhesive restorative techniques provide clinicians with versatile treatment options. Clinical studies demonstrate favorable survival rates and long-term success, positioning FRC FDPs as reliable alternatives to conventional restorations. Emerging technologies such as CAD/CAM and 3D printing further broaden their scope and precision. Conclusions: FRC FPDs have evolved from interim solutions to predictable, long-term restorations. With ongoing technological innovations and clinical validation, they are poised to become a mainstream treatment choice in prosthodontics. FRC FPDs offer a durable, aesthetic, and cost-effective solution aligned with minimally invasive dentistry, reducing tooth preparation while improving patient-centered outcomes.
