A dental implant system having a dental implant, an abutment and a threaded screw is provided. The abutment has a guiding and lock structure and the dental implant has a complementary guiding and lock structure, for associating the abutment to the dental implant, with each guiding and lock structure having an anti-rotational structure. Threaded engagement of the threaded screw to a threaded section of the dental implant is not possible, when the anti-rotational structure of the abutment is held in an intermediate position on the anti-rotational structure of the dental implant, which intermediate position is a position where the longitudinal axes of the guiding and lock structures of the abutment and of the dental implant are coaxial with one another.
