A sinterable and/or fusible ceramic mass is disclosed, having a long-term stable compound of crystalline phases of apatite, wollastonite, titanite and optionally cristobalite, which is stabilized by a glass phase, and a production process therefor. The ceramic mass can be obtained by sintering a mixture comprising at least the constituents SiO, CaO, PO, MgO, CaFand TiO, on their own or in combination with at least one alkali oxide, the alkali oxide being chosen from NaOand KO. The invention further relates to uses of the sintered material in the form of shaped articles for strengthening, cleaning, roughening or polishing surfaces of medical implants or as a final prosthesis.
