Method of identification of the positioning of references in the construction of orthodontic appliances; it contemplates the use of a single positioning body both for positioning the analogs and for guiding the fitting of miniscrews in the patient's mouth. The use of the positioning body as a positioning means of the analogs on the initial plaster mold is prior to the use as a reference guide for fitting the miniscrews in the patient's mouth. The positioning element is implemented starting from a virtual image obtained by digital scanning of a model of the arch or oral imprint and software overlapping of one or more CAT images (CBCT); said virtual image also containing one or more references for positioning virtual miniscrews, and wherein said virtual miniscrews also identify the position of the reference analogs on which the orthodontic appliance should be constructed.
