  • Reinforcing preform in the form of a meshed grid and composite material with preimpregnated fibers for a dental prosthesis, and method for producing the grid
    Patent number: 8597762
    Abstract: A preform made of composite material designed to be formed on a laboratory model and to be integrated in a base plate of a dental prosthesis. The preform comprises a grid formed by a meshing of weft threads and warp threads coated in an impregnating resin, the space between the meshes being exempt of fibers and resin, and determining a surface of free spaces of more than 25% of the total surface of the grid. The weft threads are fixed onto the warp threads at the nodes of the meshing to enable the preform to be handled and to be formed on a laboratory model, without the impregnating resin creeping into the spaces of the meshes.

  • Extractible anchoring post made from composite material
    Patent number: 8062035
    Abstract: A canal anchoring post formed by a single composite material comprising at least an organic matrix, particles and fibers. The particles and fibers are distributed in the organic matrix with respective volume proportions varying progressively and radially from the central longitudinal axis to the periphery of said post. In addition, the respective variations of the volume proportions of particles and fibers are opposite and the sum of the volume proportions of particles and fibers is radially constant from the central longitudinal axis to the periphery of said post.
