METHOD FOR MEASURING HUMAN MANDIBLE VOLUME SURFACE PARAMETERS

摘要

FIELD: medicine. ^ SUBSTANCE: method involves determining volume surface coordinates by applying automated measurement method without contact with technical vision stereo TV system. Reference points are marked with white paint on patient face in advance. The first chewing test resistant to spittle action is introduced. Movements of the points are recorded in making pictures during chewing test. The received pictures are used for determining the point coordinates. Then the second and the third test are introduced showing no resistance to spittle action. Taking pictures and reference points coordinates-measuring processes are repeated, and damped harmonic oscillation plots and their exponential components are built on the received coordinate data. Their reference point coordinates are sent to automated orthopedic articulator unit for reproducing mandible movements. ^ EFFECT: facilitated data acquisition process; high accuracy of measurements. ^ 7 dwg
