FIELD: medicine.SUBSTANCE: group of inventions relate to medical equipment, is intended for application in manufacturing fully detachable dental prostheses and includes versions of sets of dental prosthetic impression trays. In accordance with first version set of dental prosthetic impression trays contains upper and lower trays. Upper tray is made in size for placement in patient's oral cavity after placement of material for obtaining first impression of patient's gum in it. Lower tray contains first component and a pair of second components. First component is made in size for placement in patient's oral cavity after placement of material for obtaining second impression of patient's gum on it, with first component being curved relative to central part with formation of right end part and left end part. Pair of second components is reversibly connected to first component, with right part of said pair of second components being connected with right end part of first component, left part of said pair of second components being connected with left end part of first component. Size of lower tray corresponds to size of pair of second components, connected with first component. Pair of second components is detachable from first component after obtaining second impression with upper tray, containing first impression and first component of lower tray, containing second impression, being adapted for joint introduction into oral cavity for measuring jaw ratio, such as vertical distance and central ratio. Clearance, formed between upper tray, containing first impression, and first component of lower tray, containing second impression, is made in size for introduction of material for registration of bite in order to determine bite.EFFECT: inventions make it possible to reduce procedure duration and number of patient's visits to dentist for dental prosthesis manufacturing, with provision of good dental prosthesis fitting for patient.23 cl, 5 dwgГруппа изобретений относится к ме
