Method for manufacturing an implant made of a hybrid material for filling bone defects, for bone regeneration and for bone tissue engineering, characterised in that it comprises the following steps: a) selecting a bioactive glass M based on SiO 2 and CaO, optionally containing P 2 O 5 and/or optionally doped with strontium, b) selecting a biodegradable polymer P which is soluble in at least one solvent S1 and insoluble in at least one solvent S different from the solvent S1, c) selecting microspheres of a porogenic agent A that have diameters and sizes that correspond to the diameters and sizes sought for the pores in the material forming the implant to be manufactured, this porogenic agent A being: - made of a polymer that is insoluble in the at least one solvent S1 and soluble in the at least one solvent S, the at least one solvent S wherein the material of the biodegradable polymer P is insoluble and the at least one solvent S wherein the material of the porogenic agent A is soluble being identical, d) introducing microspheres of the porogenic agent A into a mould that has the shape and the size sought for the implant, these microspheres forming a compact stack that corresponds to the shape and the size of the pores to be obtained in the implant material, and representing at least 60% by volume, preferably 70% by volume with respect to the total volume of the porogenic agent A-biodegradable polymer P-alkoxide precursors of the bioactive glass M mixture, e) introducing the biodegradable polymer P into the alkoxide precursors of the bioactive glass M, f) introducing the mixture obtained in step e) into the mould, g) gelling the mixture contained in the mould after step f), h) unmoulding the mixture obtained in step g), i) removing microspheres of porogenic agent A by washing with the solvent S. a) selecting a bioactive glass M based on SiO 2 and CaO, optionally containing P 2 O 5 and/or optionally doped with strontium, b) selecting a biodegradable polymer P which is soluble in at least one solvent S1 and insoluble in at least one solvent S different from the solvent S1, c) selecting microspheres of a porogenic agent A that have diameters and sizes that correspond to the diameters and sizes sought for the pores in the material forming the implant to be manufactured, this porogenic agent A being: - made of a polymer that is insoluble in the at least one solvent S1 and soluble in the at least one solvent S, the at least one solvent S wherein the material of the biodegradable polymer P is insoluble and the at least one solvent S wherein the material of the porogenic agent A is soluble being identical, - made of a polymer that is insoluble in the at least one solvent S1 and soluble in the at least one solvent S, the at least one solvent S wherein the material of the biodegradable polymer P is insoluble and the at least one solvent S wherein the material of the porogenic agent A is soluble being identical, d) introducing microspheres of the porogenic agent A into a mould that has the shape and the size sought for the implant, these microspheres forming a compact stack that corresponds to the shape and the size of the pores to be obtained in the implant material, and representing at least 60% by volume, preferably 70% by volume with respect to the total volume of the porogenic agent A-biodegradable polymer P-alkoxide precursors of the bioactive glass M mixture, e) introducing the biodegradable polymer P into the alkoxide precursors of the bioactive glass M, f) introducing the mixture obtained in step e) into the mould, g) gelling the mixture contained in the mould after step f), h) unmoulding the mixture obtained in step g), i) removing microspheres of porogenic agent A by washing with the solvent S.
