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