Fabrication of a maxillofacial prosthesis using a computer-aided design and manufacturing system.
J Prosthodont. 2004 Sep; 13(3):179-83.JP

Abstract

PURPOSE

Maxillofacial prostheses are usually fabricated on the basis of impressions made with dental-impression material. The extent to which the prosthesis reproduces normal facial morphology depends on the clinical judgment of the individual fabricating the prosthesis. This paper describes a computer-aided design and manufacturing (CAD/CAM) system for the fabrication of maxillofacial prostheses. This system will provide a more consistently accurate reproduction of facial morphology.

MATERIALS AND METHODS

Facial measurements were taken using a non-contact three-dimensional laser morphological measurement system. The measurements were sent to a computer numerical controlled (CNC) milling machine to generate a cast of the patient's face for the fabrication of prosthesis.

RESULTS

Facial contours were measured using a laser. This method minimizes patient discomfort and avoids soft tissue distortion by impression material. Moreover, the digital data obtained is easy to store and transmit, and mirror-images can be readily generated by computer processing.

CONCLUSION

This method offers an objective, quantified approach for fabricating maxillofacial prostheses.
