Patent ID: 7972434

Claim:
A medical implant comprising: at least one of: (i) a non-cured ceramic material comprising: at least one silicate with Ca as the main cation with a resorption rate less or equal to that of bone in-growth rate, the at least one silicate being the main binding phase in a cured material; at least one second binding phase based on phosphates and/or sulphates in an amount of less than 20 weight-% of the main binding phase, the at least one second binding phase comprising a soluble glass; and optionally, additives selected from the group consisting of an inert phase, additives that make a cured material radiopaque, and mixtures thereof, wherein, the at least one Ca-silicate is present in an amount of greater than 50 weight-% of the ceramic material; and (ii) a cured chemically bonded ceramic material having for high-strength bioelements used as a resorbable or partly resorbable biomaterial, the cured ceramic material comprising: a main binding phase comprising at least one silicate with Ca as a main cation with a resorption rate less or equal to that of bone in-growth rate, at least one second phase based on phosphates and/or sulphates in an amount of less than 20 weight-% of the main binding phase, the at least one phase comprising soluble glass, and optionally, additives selected from the group consisting of an inert phase, additives that make the material radiopaque, and mixtures thereof, wherein, the at least one Ca-silicate is present in an amount more than 50 weight-% of the cured ceramic material.
