ABSTRACT:
Oral and extraoral prosthetic constructions of composite material with considerable fiber content, and in particular, jawbone anchored dental bridges of reinforced plastic, are made by the following method. A number of mutually retracted tubularly braided fibers (1), possibly in combination with continuous fiber strands, so-called roving, together constitute a fiber system which is packed in a tube, hose (2) or the like which is sealed and serves as outer packaging. A suitable matrix material, for example acrylic plastic, is injected into the hose for impregnation (wetting) of the enclosed fiber system, whereafter the hose (2) is removed. The fiber system is then polymerized to form a finished prosthesis blank in a mold. The prosthesis blank is then given suitable form and appearance by conventional after treatment.
