Superstructure (300) for a dental implant comprising a fixing section (30), comprising a cavity-shaped articulation basin with a spherical shape with a fixing surface (32), and a main section (31), being said superstructure (300) designed for attachment to a ball having a positive spherical shape of an osteointegrated dental implant through the fixation section (30), in which the main section (31) comprises a passage (110) for housing a sleeve (111) or a screw hole (55), in which part of said passage (110) or part of said screw hole (55) forms an opening in the fixing surface (32), so that there is a perpendicular distance between the center of the spherical cavity and the central axis of the passage (110) or the screw hole (55), and in which the superstructure (300) further comprises a fixing part (33) suitable for fixing the ball of a dental implant, creating therefore to a ball joint, and control means (34), the control means (34) being functionally connected to the fixing part (33), characterized by the fact that the control means (34) are suitable for activating the part (33) of fixation by manipulating the fixing part (33) to fix the fixing section (30) to the dental implant.Superestructura (300) para un implante dental que comprende una sección (30) de fijación, que comprende una cuenca de articulación en forma de cavidad con una forma esférica con una superficie (32) de fijación, y una sección principal (31), estando diseñada dicha superestructura (300) para su unión a una bola que tiene una forma esférica positiva de un implante dental osteointegrado a través de la sección (30) de fijación, en la que la sección principal (31) comprende un paso (110) para alojar un manguito (111) o un orificio (55) de tornillo, en la que parte de dicho paso (110) o parte de dicho orificio (55) de tornillo forma una abertura en la superficie (32) de fijación, de modo que existe una distancia perpendicular entre el centro de la cavidad esférica y el eje central del paso (110)
