METHOD OF MANUFACTURE OF TOOTH SET-UP Russian patent published in 2021 - IPC A61C9/00 

FIELD: dentistry.

SUBSTANCE: invention relates orthopedic dentistry, particularly to methods of modeling the teeth of a patient. A method for manufacturing of the model of teeth is proposed characterized by stages of producing an impression of the oral cavity on the impression material with an impression spoon, scanning the impression, transferring a digital image of the impression and executing the model. At the stage of scanning the impression, the impression and the impression tray are placed into a volumetric scanning device made in form of paired short-focus cameras, a light grid is created on the surface of the impression with the specified coordinates Xi and Yi of each i^th point of intersection of the lines of the light grid, the planes of camera recording are superimposed on each other , the deviations ΔXi = Xi-Xi-1 and ΔYi = Yi-Yi-1 of each of the i^th points of intersection of the light grid lines for the sequences of shots received from each of the cameras are calculated and formed by the received values of isoline deviations, intermediate values of deviations are calculated, and a digital model of teeth is created, after receiving a digital image of the impression the image is inverted and a 3D model of the teeth is produced by layer-by-layer printing using a 3D printer.

EFFECT: invention improves quality of delivery of operative medical dental care to the patient.
