A position localizer device for oral, dental and maxillofacial prostheses has a single body with a longitudinal axis and includes a portion having a body in the form of an irregular polyhedron, on whose upper polygonal side a portion is fixed in the form of a spherical body and on whose lower polygonal side there is a connection element for coupling with the interface of a respective element to be positioned. The polyhedric body, the spherical body and the connection element of the device are positioned coaxial with the axis of the body of the localizer device. A localizer according to the invention offers the advantage of obtaining a perfect adherence between the scanned surfaces and the surfaces of the device and the perfect coupling of the scanned surfaces with the mathematical model present in the database.
