The final CAD scene. (A) details of the individual abutment in position: the technician will model the final zirconia crown over it; the dental technician can model the final crown on a library file. (B) CAD design of the final crown. The software is capable to automatically detect the margin line, because the final crown is modelled on the original CAD design of the individual hybrid abutment in the correct position, and not over a mesh. The technician can, anyway, modify the margin line, but this is not recommended because the software is able to detect it perfectly, better than the human eye
