FIELD: medicine.
SUBSTANCE: invention relates to medicine, in particular to dentistry and is applicable in making stone models of jaws in treating patients sufferingfrom severe periodontal disease, parodontosis and other diseases characterised by disordered axes of teeth, including a fanlike divergence. Two narrow bands with one-side adhesive coating are applied for taking a palatal vault impression on the bed or a dental or alveolar process impression of the perforated tray on the bed. The perforated tray is coated with an impression material and introduced into the patient's oral cavity. After the impression material hardens, the tray is removed from the oral cavity and the stone model is poured. After cast is crystallised, the perforated tray is first removed from the stone model by extending the band ends brought out on an outer surface of the tray borders. That is followed by fragmental removal of the impression material from the stone model by cutting the impression material on the upper jaw model first along a projection of the alveolar processes and palatine suture; then transections are performed within the molars, premolars and canines on the models of the upper and lower jaws.
EFFECT: by separating the impression tray from the impression material to be fragmented, the method ensures preserving the dental integrity of the stone model when removed from the impression material and the tray.
