Ma. Freilich et al., DEVELOPMENT AND CLINICAL-APPLICATIONS OF A LIGHT-POLYMERIZED FIBER-REINFORCED COMPOSITE, The Journal of prosthetic dentistry, 80(3), 1998, pp. 311-318
Statement of problem. After 30 pears of intermittent reports in the li
terature, the use of fiber reinforcement is just now experiencing rapi
d expansion in dentistry. Purpose. This article describes the developm
ent and use of a continuous, unidirectional fiber-reinforced composite
as a framework for the fabrication of fixed prostheses. Methods. By u
sing various matrix materials and fibers, a number of fiber-reinforced
composite formulations were evaluated with the goal of creating a sys
tem with optimized mechanical properties and handling characteristics.
Fiber-reinforced composite based on a light-polymerized BIS-GMA matri
x has been used clinically to make 2-phase prostheses comprised of ail
internal glass fiber-reinforced composite substructure covered by a p
articulate composite. The clinical and laboratory procedures required
for the fabrication and use of reinforced composite fixed prostheses a
re described for laboratory-fabricated complete or partial coverage fi
xed prosthesis and chairside prosthesis. Results. Although additional
clinical experience is needed, fiber-reinforced composite materials ca
n be used to make metal-free prostheses with excellent esthetic qualit
ies.
