  • Double dental implant that remains stable in the presence of periimplantitus
    Patent number: 11234797
    Abstract: An implant formed by two implants: an upper implant and a lower implant, the upper implant being removable. The implant differs from conventional implants in that the body of the implant has a second polished collar corresponding with the beginning of the lower implant. The two implants are connected by a screw located in the lower part of the upper implant of which it forms a part, the screw engaging with the thread of the lower implant. The connection between the two implants is circular, as it must allow anticlockwise rotation when removed.
