| 摘要 | A fiber-reinforced composite material fro dental restorations, wherein the reinforcing glass fibers comprise a radiopacity-imparting agent, and are therefore inherently radiopaque. Preferably, the glass fibers comprise tantalum oxide, in an amount from about 5 to 60 percent by weight of the total glass composition and most preferably from about 10 to about 25 percent by weight of the total glass composition. The radiopaque fiber-reinforced composite is particularly useful as a structural component for bridges or a tooth restoration after endodontic treatment. | ||||||
