[Research and development for the CAD system of maxillofacial prosthesis].
OBJECTIVE
To establish a CAD system of maxillofacial prostheses.


METHODS
The maxillofacial prosthesis CAD system, which included mirror technique, boolean operation and use of FreeForm software, was introduced in detail by use of two clinical cases of auricular and orbital prostheses.


RESULTS
The CAD system of maxillofacial prosthesis was successfully established. The 3-D digital images of defected sides of two cases were quickly and conveniently obtained, which were symmetrical and harmoniously match to the deficient sides.


CONCLUSIONS
The established CAD technique is a useful system in maxillofacial area. It may be applied in clinic in future.
