A bendable castable abutment for the manufacture of a dental prosthesis framework, said castable abutment including: • a fixing base provided with a first complementary coupling configuration with part of a dental implant or of a dental implant analogue intended for coupling the fixing base to the dental implant or to the dental implant analogue, and provided with a through hole intended for placing a fixing screw of the castable abutment to the dental implant or to the dental implant analogue; • a hollow tubular wall made of castable material and connected to the fixing base, said tubular wall comprising a hollow tubular joint, made of an elastically deformable material, adjacent to the fixing base, made up of a succession of pairs of frustoconical rings joined in succession forming an accordion section, each pair of rings being made up of a first frustoconical ring with a base and a truncated cusp and a second frustoconical ring, each first frustoconical ring being joined at the base thereof to the base of a second frustoconical ring, defining in said joining an annular hinge, and being joined at the truncated cusp thereof to the truncated cusp of another second frustoconical ring, defining in said joining another annular hinge; said base of the first frustoconical rings and of the second frustoconical rings being of the same diameter and said truncated cusp of the first frustoconical rings and of the second frustoconical rings being of the same diameter; characterised in that • the height of the first frustoconical rings is different from the height of the second frustoconical rings; and • each first and second frustoconical rings is generated by deforming the tubular wall to generate tensions within the material. • a fixing base provided with a first complementary coupling configuration with part of a dental implant or of a dental implant analogue intended for coupling the fixing base to the dental implant or to the dental implant analogue, and provided with a through hole intended for placing a fixing screw of the castable abutment to the dental implant or to the dental implant analogue; • a hollow tubular wall made of castable material and connected to the fixing base, said tubular wall comprising a hollow tubular joint, made of an elastically deformable material, adjacent to the fixing base, made up of a succession of pairs of frustoconical rings joined in succession forming an accordion section, each pair of rings being made up of a first frustoconical ring with a base and a truncated cusp and a second frustoconical ring, each first frustoconical ring being joined at the base thereof to the base of a second frustoconical ring, defining in said joining an annular hinge, and being joined at the truncated cusp thereof to the truncated cusp of another second frustoconical ring, defining in said joining another annular hinge; said base of the first frustoconical rings and of the second frustoconical rings being of the same diameter and said truncated cusp of the first frustoconical rings and of the second frustoconical rings being of the same diameter; • the height of the first frustoconical rings is different from the height of the second frustoconical rings; and • each first and second frustoconical rings is generated by deforming the tubular wall to generate tensions within the material.
