A position localizer device for oral, dental and maxillofacial prostheses, consisting of a single body with a longitudinal axis (4) and comprising a portion consisting of a body (3) in the form of an irregular polyhedron, on whose upper polygonal side (6) a portion is fixed in the form of a spherical body (2) and on whose lower polygonal side there is a connection element (18) for coupling with the interface of the respective element to be positioned. The polyhedric body (3), the spherical body (2) and the mentioned connection (18) of the device of the invention are positioned coaxial with said axis (4) of the body of the same localizer device (1). With respect to the known art considered above, the localizer of the invention offers the advantage of obtaining a perfect adherence between the surfaces scanned and the surfaces of the device itself and the perfect coupling of the scanned surfaces with the mathematical model present in the database.
