Abstract:
Objective: To obtain the data of the surfaces of stand ar d posterior teeth crowns with an improved measurement system, so as to lay the f oundation for fabrication of dental prosthesis with computer aided design and la ser solid forming technology. Methods: Standard posterior teeth models were measured with a numerical controlled miller and a new data col lection system by cutting and scanning layer by layer, and the 3 dimension (3 D) shape of the models was reconstructed by image processing with a special soft ware. Results: Data of image profile and 3D shape of sixte en posterior teeth crowns were obtained. Precise configuration was acquired.Conclusion: Data of image profile can be easily and clearly ob tained by the improved measurement system with no measuring blind spot.
