Abstract

Ceramic filler compositions of customized shapes (Figures 1-30) according to the present invention, include ceramic and glass-ceramic particles having a customized shape which provides mechanical locking within a resin matrix giving significantly improved fracture toughness performance for a resin/glass or ceramic composite system. The material has particular application as a tooth filling material with significantly improved wear resistance. The wide range of unique-shaped filler particles are produced using wet chemistry methods according to the invention of preparing the ceramic particles for use in a resin matrix composite material. Such composite materials have a very wide application, especially as a dental composite filling material for restoring a tooth.

Claims (9)

1. A filled dental material having improved mechanical properties comprising:
a resin matrix and a filler component;
wherein said filler component comprises from about to about 35 percent by weight of ceramic particles having a preselected shape;
said preselected shape selected from the group consisting of spheres, doughnuts, multi-dimples, hollow spheres, nuggets, rods, fibers, and mixtures thereof;
wherein the filled dental material is improved due to mechanical interlocking of the ceramic particles within the matrix.
2. A filled dental material as in claim 1, wherein said multi-dimpled shaped particles are porous.
3. A filled dental material as in claim 1, wherein said multi-dimpled shaped particles are solid.
4. A filler material for a dental restorative composition comprising:
a plurality of ceramic particles having a preselected shape selected from the group consisting of spheres, doughnuts, multi-dimples, hollow spheres, nuggets, rods, fibbers, and mixtures thereof
5. A filler material as in claim 9, wherein said filler is produced by wet chemical synthesis of a material selected from the group consisting of zirconium, silica, barium, titanium, strontium, alumina, mullite or mixtures thereof.
6. A filler as in claim 5, wherein said filler i5 a mixture of silica and from about 3 to about 40 percent by weight of ZrO2.
7. A filler as in claim 5, wherein said filler is a mixture of silica and from about 10 to about 80 percent by weight of BaO.
8. A filler as in claim 5, wherein said filler is a mixture of silica and from about 3 to about 40 percent by weight of TiO2.
9. A filler as in claim 5, wherein said filler is a mixture of silica and from about 10 to about 80 percent by weight of SrO:
