    • A crown-root reconstitution system and method of manufacturing a physiological dental securing peg in which a crown reconstituting material (3) is placed between a peg (1) and sound dentine walls (2a). The peg is formed of a composite material and includes high strength fibers (5) embedded parallel to one another, elongated in its axial direction, continuous from one end to the other end thereof. An epoxy resin matrix is formed, and a transverse modulus of elasticity of the order of magnitude of the average of that of the dentine in the amount of 18 GPa and a longitudinal compression-tensile strength and shear strength greater than corresponding average values for the dentine is provided by tensioning all of the fibers equally and pre-stressing all of the fibers in traction. The peg is manufactured by extruding the resin around a wick of continuous fibers which are all equally tensioned and pre-stressed in traction, allowing the resin to harden, cutting the ring of composite material after the resin is hardened, and machining the peg by slicing so as to obtain two coaxial cylindro-conical parts of different diameters, in line with each other, each comprising a cylindrical shank (6, 8) followed by a respective truncated part of a frustrum of a cone (7, 9) converging towards the apex of the peg.

    • A dental post includes a composite material such as long fibers embedded in a resin matrix, and is able to transmit visible radiation when it is lit by a dental lamp to ensure polymerization of a product for setting in a tooth's root canal. The post, which has a specific color determined at ambient temperature before insertion into said canal, and which contains at least one thermochromic substance able to provide said specific color, loses its color when in place in the canal. A method for forming the dental post and a kit including a plurality of dental posts and drills are also disclosed.
