The invention relates to a superstructure support (20) as part of a prosthetic tooth replacement (1) between an implant body (10) and a superstructure, comprising a hollow implant post (23), a hollow implant pin (50), and an implant flange (31) lying therebetween. The cavity zones (67, 62) of the implant post (23) and of the implant pin (50) transition into each other. The cavity zones have respective center lines (69, 63), which include an angle of 60 to 86 angular degrees. The cavity zone (62) of the implant pin (50) has a screw head seat surface (65) that widens toward the implant flange. At least some areas of the implant flange form a supporting enveloping surface (37), which is oriented toward the implant post (23) and the outer edge (33) of which spans a reference plane (38), which is perpendicularly intersected by the center line (69) of the post-side cavity zone (67). The center lines of the implant post (23) and of the implant pin (50) intersect or cross below the reference plane (38). By means of the invention, a superstructure support (20) for the prosthetic tooth replacement is improved in such a way that a secure and lasting screwed connection to the implant body is ensured.
