Abstract [eng] The main reason of insufficient accuracy of sur-faces reconstruction in previously created models of the human masticatory system is high irradiance dose for the investigative person during the computed tomography scanning. This article presents original modeling technique based on the data of two different scanning systems. In this work geometrical parameters of the bony structures and roots of the teeth were estimated using computed tomogra-phy, and teeth occlusal surfaces were scanned with three-dimensional optical scanner. It was found that using new hybrid scanning and modeling technique the minimal area of reconstructed elements decreased from 0.134×0.134 to 0.05×0.05 mm and effective irradiance dose decreased from 3.78 to 0.97 mSv in comparison with the technique, based only on computed tomography scanning. Hence, the new technique enabled 2.7 times increment of teeth occlu-sal surfaces reconstruction and retention of realistic spatial arrangement of system’s elements without an increment of irradiance effective dose for the investigative person.
