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 structuralcomponent for bridges or a tooth restoration after endodontic treatment.
Matériau composite à fibres pour restauration dentaire. Les fibres de verre de renforcement comprennent un agent d'opacité aux rayons X et sont, par conséquent, opaques à ce rayonnement de façon inhérente. De préférence, les fibres de verre sont constituées d'oxyde de tantale dans une quantité d'environ 5 à 60 % en poids de la composition totale en verre (préférablement d'environ 10 à 25 % en poids de la composition totale en verre). Ce composite est particulièrement utile comme composant structurel pour les ponts ou la restauration dentaire après un traitement endodontique.
