provided with a T-attachment mesially for prospective planning and fabricated using
translucent Ceramill Zolid.
After sintering, all anatomical frameworks were further characterised and glazed
using the Ceramill Stain & Glaze Kit. The degree of glaze was then customised in the
same way as with conventional build-up porcelain using silicone rubber polishers and
pumice or diamond paste (Fig 25).
In this case, the tertiary structure on teeth 24 and 25 was contoured fully anatomi-
cally reduced circumferentially. The crown framework on tooth 24 was also reduced
buccally to create space for a porcelain shoulder.
Because it has been possible to incorporate comparable material properties into Cera-
mill Zi and Ceramill Zolid, despite their different translucency, they can easily be used
together or separately to suit the individual requirements of the patient and enable a
much wider range of restoration options to be fabricated using the Ceramill CAD/CAM
system, as the author was able to demonstrate using the example of a single model
(Figs 26 to 28).
