Set of components for dental prosthetic restoration, comprising a ceramic dental implant intended to be fitted in the upper jawbone or lower jawbone of a patient and extending along a first longitudinal axis (I-I) between a proximal end and a distal end, with an inner connection seat extending from the distal end in the direction of the proximal end, in which: - the inner connection seat has at least one portion of non-circular cross section, - the set comprises an internally threaded insert, configured in such a way as to be mounted in the portion of non-circular cross section of the inner connection seat of the dental implant by being rotationally indexed therein about the first longitudinal axis (I-I), - the set comprises a fixing piece with a first axial through-passage having a cross section of sufficient dimensions for the passage of a threaded element intended to cooperate by screwing with the internally threaded insert, configured to engage in a radial seat formed in the lateral wall of the inner connection seat of the dental implant in such a way as to form an axial abutment opposing an extraction of the internally threaded insert from the portion of non-circular cross section of the inner connection seat, - the set comprises a fixing screw having a screw head from which there extends a screw shank provided with a threaded portion intended to be received by screwing in said internally threaded insert, - the fixing piece extends between a first end, intended to engage in the inner connection seat of the dental implant, and a second end, characterized in that: - the set has a transfixed dental prosthesis core of ceramic comprising a second through-passage formed by first and second successive passage portions, said first passage portion extending from a proximal end of the transfixed dental prosthesis core along a second longitudinal axis (II-II), and said second passage portion continuing the first passage portion in such a way that the first and second passage portions form a non-zero angle between them, - the first passage portion of the transfixed dental prosthesis core has transverse dimensions permitting reception of the second end of the fixing piece and the screw head by axial penetration along the second longitudinal axis (II-II) from the proximal end of the transfixed dental prosthesis core, - the screw head and the second end of the fixing piece are configured so that a relative movement in translation of the fixing screw toward the proximal end of the dental implant along the first longitudinal axis (I-I) causes a radial expansion of the second end of the fixing piece, in order to retain the transfixed dental prosthesis core on the dental implant. -
