[Construction of the digital models of masseter and temporal muscles with three-dimensional laser scanning].
OBJECTIVE
To explore a new method for establishing digital models of the masseter and temporal muscles and superficial soft tissue using three-dimensional laser scanning technique.


METHODS
One adult male cadaveric head without malformation was dissected to expose the superficial portion of the masseter and temporalis. Multiple aspects of the sample were scanned with three-dimensional laser scanning system, and the point clouds of the masseter and temporal muscles were generated. The specimen was scanned again after the masseter and temporal muscles had been removed. The digital model of the muscles was reconstructed with the point clouds using Geomagic software, and the morphology of the muscle model was observed and measured.


RESULTS
The 3-D digital models of the masseter and temporal muscles with the anatomical characteristics were reconstructed based on the point clouds using Geomagic 8.0 software.


CONCLUSIONS
The digital model of the muscles can vividly demonstrate the muscle contours, which provides a basis for morphological study and biomechanical analysis of the muscles.
