It holds short discrete fibers that are uniformly distributed and circumstances oriented. Acrylic tubs tend to be more expensive than fiberglass and have a deeper color layer that can be more durable than the relatively thin gel coat used on fiberglass tubs. 19 Effect of fiber content on elongation at break of CAB reinforced with various cellulose fibers. Fibers such as graphite and glass have excellent resistance to creep, while the same is not true for most resins. J Clin Diagn Res 20012;7(4):772-775. The transparent, reinforced composite polymeric fiber according to claim 2 wherein the first polymer and said second polymer have the same, or very nearly the same, refractive index. The need for renewable fiber reinforced composites has never been as prevalent as it currently is. When the fiber cannot be closely adapted to the teeth, the composite resin is thicker, decreasing the durability of the fiber-reinforced composite. But there are several disadvantages with this appliance such as the need for a cast or a working model, decalcification of the abutment tooth, loosening because of breakage or dissolution of the luting agent, tendency to get embedded in the soft tissue and the possibility of metal allergy.
