[The application of three-dimensional model in the oral and maxillofacial surgery].

OBJECTIVE
To exploit the three-dimensional model technique and apply it in the oral and maxillofacial surgery.


METHODS
Using CT and rapid prototype technique to make three-dimentional model and used it for the therapy of the comminuted zygomatic features, jaw bone asymmetry, defects after tumor removal, and implantations.


RESULTS
By using three-dimensional models eight patients with comprehensive bone defects had good results.


CONCLUSIONS
Three-dimensional models can help surgeons in many ways for the therapy of the oral and maxillofacial deformities.
