Abstract
A teeth prosthesis for an upper maxilla includes an infrastructure, a suprastructure, and an assembly for a removable attachment of the suprastructure with the infrastructure. The infrastructure includes at least three implants, one connection bar, and an assembly for removably fastening the connection bar with and against each head of the implants. The suprastructure includes a first member made of cast metal or alloy having an intrados provided with an opening giving access to a housing of such size and depth to allow the housing of the connection bar therein, a second member immovably attached with the first member, and a set of teeth immovably attached with the first member and the second member. The assembly includes two first fastening members, and a second fastening member. The invention is also directed to a method for the manufacture of such a teeth prosthesis and to a kit comprising prefabricated parts useful for the manufacture of the prosthesis.
