Abstract
The invention relates to a coating composition and an anchorage component for implants having a completely or partly coated surface. The coating comprises a filling material of highly porous spherical particles having a diameter from about 10 to about 200 .mu.m and a pore volume from about 25 to about 80% on the basis of solid calcium compounds and a resorbable binding agent (matrix).
Claims15
A resorbable coating composition for anchorage components for surgical implants, consisting of a dried resorbable filling material and a resorbable binding agent, wherein the filling material consists of porous spherical particles containing solid tricalcium phosphate or apatite and having a diameter from about 15 to 50 .mu.m and a pore volume from about 25 to about 80%, the pores of the spherical particles being filled with the resorbable binding agent.
A coating composition for anchorage components for surgical implants, consisting of a dried resorbable filling material and a resorbable binding agent, wherein the filling material consists of porous spherical particles containing solid tricalcium phosphate or apatite and having a diameter from about 15 to 50 .mu.m and a pore volume from about 25 to 80%, the pores of the spherical particles being filled with the binding agent and at least one additive which is a member selected from the group consisting of hemostypics, osteogenic substances, antibiotics, vaso-active substances and hormones acting on bone.
An anchorage component for surgical implants having a fully or partly coated surface, with a coating composition consisting of a dried resorbable filling material and a resorbable binding agent, wherein the filling material consists of porous spherical particles containing solid tricalcium phosphate or apatite and having a diameter from about 15 to 50 .mu.m and a pore volume from about 25 to about 80%, the pores of the spherical particles being filled with the binding agent and additional reinforcing material.
A method of filling in a defect in a bone which consists of anchoring in the bone a surgical implant having an anchorage component which has a fully or partly coated surface, with a coating composition which consists of a dried resorbable filling material and a resorbable binding agent, wherein the filling material consists of porous spherical particles containing solid tricalcium phosphate or apatite and having a diameter from about 15 to 50 .mu.m and a pore volume from about 25 to about 80%, the pores of the spherical particles being filled with the binding agent.
