Dental implant system for mounting a dental superstructure is disclosed. Enossal, gingival, transgingival sections plus implant head are integrated into a single-piece implant body. The enossal and gingival sections have geometries derived from diagnostic patient data and, thus, correspond geometrically precisely to the shape of the patient's jawbone and the drilled implant cavity, completely filling those portions of the cavity. The superstructure covers the entire surface of the implant head, filling out the rest of the cavity. The surface structure of the dental implant has no gaps in it and portions of it are textured so as to facilitate complete fusing of tissue to implant, thereby preventing formation of gum pockets. Sections of the dental implant are rotationally asymmetrical, so as to ensure proper location of the implant in the cavity and prevent rotation. The construction of the implant also prevents the occurrence of micro-movements.
