The invention relates to an adapter (1, 1′) for attaching a dental superstructure (50) to a dental implant (30). The adapter (1, 1′) comprises a coronal attachment portion (2, 2′) for attaching the adapter (1, 1′) to the dental superstructure (50), an apical attachment portion (4) for attaching the adapter (1, 1′) to the dental implant (30) and an intermediate portion (6) arranged between the coronal attachment portion (2, 2′) and the apical attachment portion (4). The apical attachment portion (4) is a protrusion defining an apical end portion of the adapter (1, 1′) and configured to be received in a corresponding recess (32) of the dental implant (30). The protrusion is rotationally symmetric, so that the adapter (1, 1′) is rotatable relative to the dental implant (30) in the state of attachment of the adapter (1, 1′) to the dental implant (30). Further, the invention relates to a dental assembly comprising the dental superstructure (50) and at least one such adapter (1, 1′).
