The invention concerns a method for manufacturing a bone superstructure (4) and a dental implant system with an implant (5) and a bone superstructure (4) to at least partly fill bone defects (2) in a jaw (1), whereby the bone superstructure (4) has a bone side (11) which is intended to extend opposite the bone which surrounds said bone defect (2) and a free side (10) onto which the gingiva (9) should connect, whereby this bone superstructure (4) has at least one recess (6) with a circular cross section extending between said bone side (11) and said free side (10), which recess (6) has a conical wall (8) and whereby the implant (5) is conical over at least a part (14) of its height, such that it can be mounted in the recess (6) in a substantially fitting manner.
