A metal pillar for dental implants, preferably for maxillary implants that can comprise an inclined frustoconical support base, comprises an upper segment and a lower base, the latter in turn comprising a threaded shank forming a body that is solidly connected to the upper segment of the metal pillar in order to secure the same to the maxillary implant. The upper segment comprises an upper opening in the form of a shaft ending internally in a hexagonal mortise for the insertion of the corresponding wrench. The lower base also comprises a frustoconical support base, from which the threaded shank extends, having an inclination matching that of the frustoconical support base of the maxillary implant. The threaded segment of the shank includes different helix ends for determining different axial clamping position in relation to the maxillary implant. |
