摘要:
Nano-particles of calcium and phosphorous compounds are made in a highly pure generally amorphous state by spray drying a weak acid solution of said compound and evaporating the liquid from the atomized spray in a heated column followed by collection of the precipitated particles. Hydroxy apetite (HA) particles formed by such apparatus and methods are examples of particle manufacture useful in bone and dental therapies.

The present invention relates to a process for the preparation of a full-ceramic dental restoration, comprising heat pressing of a tooth coloured pressing glass on a fully or partially supporting structure of yttria doped tetragonal zirconia (YT/P), comprised of yttria doped tetragonal zirconia ceramic having a grain size, as measured by the linear intercept method, of less than 0.6 μm, wherein the pressing glass has a thermal expansion coefficient (TEC) of between 9.0 and 1.0 μm/m.K measured in the range of from 25 to 500° C.) and wherein the pressing glass has a pressing temperature of between 750 and 1000° C. In a further aspect, the invention relates to a full-ceramic dental restoration, comprising a fully or partially supporting structure of yttria doped tetragonal zirconia (YTZP) and a heat pressed tooth coloured pressing glass. which restoration is modelled to be in occlusal contact with opposing teeth and in mesio-distal contact with neighbouring teeth.
摘要:
A chemically bonded ceramic material based on calcium aluminate hydrate with additives of primarily calcium titanate, but also chemically similar compounds. The material is a biocompatible material for implants, particularly for orthopaedic and dental applications. The material possesses the properties required for an orthopaedic biocement. It cures through reaction with water and develops its strength within a short period of time, has good workability prior to curing, is shape stable, has a low heat generation during curing, and is friendly to adjacent tissues.
摘要:
A system for a chemically bonded ceramic material (CBC), comprising a composite biomaterial for preferably dental and/or orthopaedic applications. The CBC-system includes a binding (chemical cement) and inert phases with specified geometry providing the biomaterial defect tolerance through an improved fracture toughness. The invention also relates to the powdered materials and the hydration liquid, respectively, as well as the formed ceramic material.
