TEETH PROSTHESIS, METHOD OF MANUFACTURE THEREOF AND KIT USEFUL FOR THE MANUFACTURE OF THE TEETH PROSTHESIS

摘要

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 connection bar comprises at least one distinct machined portion that is sized and shaped to contact a corresponding machined member inside of the housing of the first member. The invention further relates to a method for the manufacture of such a prosthesis and to a kit comprising prefabricated parts useful for the manufacture of the latter. Such method and kit allow an easy manufacture of teeth prosthesis which are otherwise long and difficult to make.
