Process for the production of a tricalcium phosphate bone ceramic for use as bone implant, in particular for filling in cavities or for fixing bone fragments after fractures, and tricalcium phosphate ceramic moulding produced thereby
Process for the production of a tricalcium phosphate bone ceramic for use as bone implant, in particular for filling in cavities or for fixing bone fragments after fractures, and tricalcium phosphate ceramic moulding produced thereby
The invention relates to a process for the production of a tricalcium phosphate bone ceramic and to a tricalcium phosphate ceramic moulding produced thereby and having a micro- or macroporosity for increased uptake of an antiseptic, chemotherapeutic or broad-band microbiocide and having an outer coating for prolonged release of the active substance, where the micro- or macroporosity is obtained by adding to the ceramic part before the firing step, inorganic and/or organic micro- or macropore-forming substances such as sugars, ammonium bicarbonate and/or ammonium carbamate, calcium hydrogen phosphate and the like.
