[Study on computer aided design system of anterior prosthesis in terms of artificial neural network].
OBJECTIVE
This study was to develop computer aided design system of anterior prosthesis, which can improve information communication among doctors, technicians, patients and raise anterior prosthesis cosmetic effect.


METHODS
Digital camera was used for image capture; Space field method, neighboring field average method, midst value filter method, and image average method were used for image pre-process; sample teeth were constructed; anterior prosthesis were automatically designed through tooth feature extraction.


RESULTS
86 patients were prosthetically designed through this CAD system with excellent results.


CONCLUSIONS
This system implemented anterior prosthesis CAD rapidly, guided clinical application and promoted information process in the field of prosthetics.
