[A preliminary study on maxillofacial prosthesis using structured light three-dimensional scanning and rapid prototyping technique].
OBJECTIVE
To evaluate application of three-dimensional reconstruction of the facial soft tissue by use of light three-dimensional scanning system and rapid prototyping and to lay a foundation for developing the computer aided design (CAD) and computer aided manufacture (CAM) system of the maxillofacial defect rehabilitation.


METHODS
The left and right facial profiles of a volunteer were scanned with the light three-dimensional scanning system that was a self-developed one. The complete point and cloud data were obtained by transforming the image data with the Surfcaq software. Then three-dimensional reconstruction was done via transforming the point and cloud data to Geomagic studio 7.0. The final three-dimensional reconstruction was achieved by way of putting the point and cloud data together with apex nasi, external point of the orbit, mention as the mark points. The image was imported into Magics RP to triangulate and created in the thickness of 2 mm. The three-dimensional resin model was fabricated by fused deposition modeling (FDM).


RESULTS
The three-dimensional image of the facial soft tissue of the volunteer was achieved. The three-dimensional resin model of the facial soft tissue of the volunteer was also obtained.


CONCLUSIONS
Light three-dimensional scanning system was feasible for three-dimensional reconstruction.
