Method of forming a dental coping

摘要

An automated method for forming a dental coping which comprises: scanning a three dimensional image of the die of the tooth or teeth to be restored; digitizing the scanned three dimensional image into digital information, storing the digital information in a computer; feeding the digital information from the computer into a computerized numerical control cutting machine; cutting out a section of material of metallic composition into a two dimensional configuration representing a two dimensional lay out of the scanned three dimensional image, adapting the cut out section of material over the die so that the material covers the die surface in close engagement therewith to form a single three dimensional structure having the shape of the die and heat treating the structure into a coping conforming in shape to the die.
