Development and clinical applications of a light-polymerized fiber-reinforced composite

Statement of problem. After 30 pears of intermittent reports in the literature, the use of fiber reinforcement is just now experiencing rapid expansion in dentistry. Purpose. This article describes the development and use of a continuous, unidirectional fiber-reinforced composite as a framework for the fabrication of fixed prostheses. Methods. By using various matrix materials and fibers, a number of fiber-reinforced composite formulations were evaluated with the goal of creating a system with optimized mechanical properties and handling characteristics. Fiber-reinforced composite based on a light-polymerized BIS-GMA matrix has been used clinically to make 2-phase prostheses comprised of ail internal glass fiber-reinforced composite substructure covered by a particulate composite. The clinical and laboratory procedures required for the fabrication and use of reinforced composite fixed prostheses are described for laboratory-fabricated complete or partial coverage fixed prosthesis and chairside prosthesis. Results. Although additional clinical experience is needed, fiber-reinforced composite materials can be used to make metal-free prostheses with excellent esthetic qualities.
