An implantation material comprising a polymeric base of a polyacrylate, a polymethacrylate, a copolymer of an acrylate and a methacrylate or a mixture thereof and 5-35% by weight of resorbable tricalcium phosphate of a particle size of 50-300 .mu.m and an available pore volume of less than 0.1 ml/g.
A composition for use in preparing an implantation material comprising 10-50 wt.% of resorbable tricalcium phosphate of a particle size of 50-300 .mu.m and an available pore volume of less than 0.1 ml/g and 50-90 wt.% of prepolymer particles of a polyacrylate, a polymethacrylate, a copolymer of an acrylate and a methacrylate or a mixture thereof.
A composition for use in preparing an implantation material comprising 10-60 wt.% of resorbable tricalcium phosphate of a particle size of 50-300 .mu.m with an available pore volume of less than 0.1 ml/g and 40-90 wt.% of an acrylic or methacrylic monomer.
