Abstract
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, 150, 160, 170, 180, 190), a hollow implant pin (50), and an implant flange (31) lying therebetween. The cavity zones (67, 62) of the implant post (23, 150, 160, 170, 180, 190) and of the implant pin (50) transition into each other. The center lines (69, 63) include an angle of 60 to 86 angular degrees. An attachment element (5) can be arranged on the implant post (23, 150, 160, 170, 180, 190) in a rotationally fixed manner by means of an assembly joint (140), which forms an interface (141, 145). The attachment element (5) is a cap-type element. At least some areas of the implant flange (31) have a supporting enveloping surface (37). The attachment element (5) has an interface geometry (146), which can be mounted on the interface geometry (142) of the superstructure support (20) in an interlocking and/or frictional manner at least in some areas. By means of the invention, a superstructure support (20) for the prosthetic tooth replacement is improved in such a way that the interface between the im…
