A prosthetic component (3) of a dental implant (1) and an abutment (2) for its screw retention are related to the parts of a dental implant. The prosthetic component (3) comprises a fastening base (6) with a through hole (7) for a prosthetic screw (5). The base (6) is made with a connecting socket in the form of an annular recess (8) around the hole for the screw (7). The supporting lateral surfaces of the recess (8) are conical in shape, mutually coaxial and diverge outward. The abutment (2) comprises a seat for the fastening base (6) of the component (3). The seat is made in the form of an annular projection (22) around a threaded hole (21) for the screw (5). The supporting lateral surfaces of the annular projection (22) are conical in shape, mutually coaxial and converge outward. The tightness of the screw connection of the prosthetic component (3) with the abutment (2) is increased. Increased rotational stability of the component (3) relative to the abutment (2). Prevented loosening of the screw (5). Increased reliability of the screw connection. As a result, the risk of inflammatory reactions is reduced. Reduced risk of implant rejection (1).
A prosthetic component (3) with a screw retention for a dental implant (1), comprising a fastening base (6) with a through hole (7) for a prosthetic screw (5), characterized in that the fastening base (6) is made with a connecting socket in the form of an annular recess (8) around the hole (7) for the prosthetic screw (5), limited by a wall of small diameter (9) and a wall of large diameter (10) with supporting side surfaces of a conical shape, which are mutually coaxial and diverge outward.
The abutment (2) for screw retention of the prosthetic component (3) of the dental implant (1), comprising a seat for the fastening base (6) of the said component (3) with a threaded hole (21) for the prosthetic screw (5), characterized in that the seat is made in the form of an annular protrusion (22) around the hole (21) for the prosthetic screw (5), wherein this protrusion (22) has external and internal supporting lateral surfaces of a conical shape, which are mutually coaxial and converge outward.
The abutment according to item 5, characterized in that the axes of rotation of the supporting lateral surfaces are coaxial with the longitudinal axis of the threaded hole (21) for the prosthetic screw (5).
The abutment according to item 5, characterized in that the annular projection (22) is made from the condition of a smaller height of its internal supporting lateral surface relative to the height of the external supporting lateral surface with the same taper value of the said surfaces.
The abutment according to item 5, characterized in that the annular projection (22) is made with an anti-rotation element (23).
