Kleinostheim, April 5, 2005 – In future, the synthetic bone regeneration material Cerasorb® , developed by curasan AG, will serve as a worldwide reference for beta-Tricalciumphosphate.

It is essential both for scientists and industry to be able to characterise analytically pure chemical substances in a manner that is conclusive. For this purpose, chemical analysts can refer to a range of catalogues and databases such as the files maintained by the ICDD (International Center of Diffraction Data, Pennsylvania, USA). Over 164,000 solid crystalline substances have already be catalogued. This data serves as a reference, allowing the precise analysis and comparison of substances within the same class.

The former reference for beta-Tricalciumphosphate was based on an analysis of the mineral “whitlockite”, which was catalogued in 1959.

With Cerasorb® , curasan AG has succeeded in producing a >= 99% pure-phase beta-TCP which meets the highest standards in terms of purity and quality. Analytical technology has advanced considerably since 1959, and therefore reassessment had become essential, particularly in view of the ever-growing demand for pure-phase biomaterials.

Therefore, the beta-Tricalciumphosphate Cerasorb® was measured and analysed in detail at the Dr. Ermrich X-ray centre (Reinheim/Odenwald). On account of the phase purity of >= 99%, the ICDD included the relevant data in its file as a reference for highest quality. Catalogued under PDF number #55-898, it will replace the old reference from 2005 onwards, thus setting the standard for all other beta-TCP compounds.

With regard to the medical use of Cerasorb®, the product's purity allows the biological regeneration process of the bone to take place without disturbances. The material is resorbed in a controlled way, i.e. simultaneously to the formation of new bone. With Cerasorb®, the physician can offer a predictable therapeutical process and the highest possible safety for the patient.
