[The Optec hsp procedure. Concepts and laboratory fabrication].

Feldspatic porcelains are usually material in cosmetic dentistry, but they cannot be used without a reinforcement system. Aluminous or metallic frames produce a strong internal specular reflexion, which destroys the deep natural appearance of teeth. Inspired from glass ceramic industry, the concept of strengthening in Optec hsp is induced by a high level of micro-crystalline dispersion, spread in the material. Micro-crystals increase strength by division of stresses and improve the scattering of light as we observe in the natural tooth. The laboratory method is based on routine technics of porcelain building. No special equipment, or high temperature are necessary for producing, laminate veneers, inlays, onlays, crowns, and tree units anterior bridges.
