Imaging method for fabricating dental devices |
摘要 |
A method for fabricating a dental restoration is described which comprises the steps of obtaining a dental impression of a patient using dental impression material, filling the cavity defining the impression with a filler material distinguishable from the dental material defining the impression and allowing the materials to harden to a solid block, successively removing from the block thin layers and imaging each then remaining surface of the block after each successive layer is removed to define a contour of the filler material for each layer removed, each contour corresponding to a contour of the teeth, gums and palate of the patient at a corresponding known depth of the block, generating a three dimensional computer model of the teeth, gums and palate of the patient using the contours, and converting the model to a stereolithography file for producing a castable pattern of the model or machining a restoration corresponding to the model.
