the patient; if we get her approval,
we can move to the next step and
create the final veneers.
Once approval has been ob-
tained from the patient, we pro-
ceed to print the final Geller
master model and duplicate the
matrices with the special Shera
Refractory material. Since this is
Fig 25 a no-prep case, we will make ul-
tra-thin refractory veneers using
Style Ceramic from Ivoclar Viva-
dent. For the model, we used the
new Smokey White resin from
Shera.
Apply a thin layer of material
over the entire surface where the
ceramic will be applied. Place the
refractory beads on the substrate
as illustrated, at an angle of ap-

proximately 45 degrees. Use the
firing program described in the
photograph. New generations of
ceramics are now available. The
biggest advantage is that these ce-
ramic powders have the smallest
shrinkage ever and also a structure
devoid of porosity. In addition, the
ceramics contain oxapatite crys-
tals, and has the ability to recre-
ate the natural appearance of the
tooth thanks to a very high degree
of reflected incident light. Crystals
