METHOD OF COMPARING VIRTUAL MODELS OF TOOTH ROWS Russian patent published in 2009 - IPC A61C9/00 A61C13/00 A61C3/00 G06F19/00 

Abstract RU 2373893 C1

FIELD: medicine.

SUBSTANCE: invention relates to medicine, and namely - to dentistry. Method consists in the following: made are physical models of tooth rows and occlusive registrate, which is obtained by sealing of teeth during jaw lock. Surface of tooth rows of physical models is scanned, double-sided scanning of occlusive registrate is carried out, forming in such way complex digital model of occlusive registrate and virtually formed complex digital model of occlusive registrate and surfaces of models of tooth rows are compared.

EFFECT: invention can be applied for manufacturing tooth prosthesis by computer methods with application of programming technology CAD/CAM.
