Abstract: A tooth post made of composite material includes a central core (3) made of a resin matrix wherein are embedded fibers (5) which give the post (1) its main mechanical properties. The central core (3) is wrapped in a sheath (6) consisting of at least one layer of fiber (7) made of radio-opaque material.

Abstract: The present invention relates to a tooth prothesis made of composite material and to a process for fabricating said prothesis. The prothesis is characterized in that it is comprised of a central core (3), made of at least one bunch of fibers (5), for example glass fibers, the core being wrapped by a sheath (7) comprised of at least one layer of oriented, isotropic or non isotropic fibers (8a, 8b, 8c) , the fibers (5) of the central core (3) and the fibers of the sheath (7) being embedded in a curable resin, the fibers (8a, 8b, 8c) of the sheath (7) being oriented in a given angle with respect to the longitudinal axis (yy') of the prothesis (1), so as to adjust to desired respective values the longitudinal and transverse traction resistance of the prothesis (1).
