FIGS. 7-13 COURTESY OF DRS. MAURICIO JEGERLEHNER AND JORGE FLORES

a composite resin, a 3D restoration with
contours and anatomical landmarks of a
natural tooth is formed. This affects how
the light reflects back and is perceived by
the eye.
Remember the "perceived" shape, length,
and width of an anterior tooth is significantly
influenced by the specular reflections coming
from the surface morphology, heights of
contour and line angles of the buccal surface.9

Figs. 7-9: Apply dentin shade composite (here, Mosaic B1 from Ultradent) onto
the template and cut into the incisal uncured material to create a pattern of
slices to simulate dentinal lobes. Apply a translucent composite shade (here,
Gaenial Universal Flow from GC America) into the Uveneer template.

Creating an incisal
edge translucency
In some cases, more pronounced incisal
translucency is required. In such scenarios,
it is recommended to apply dentin shade on
the tooth, and before curing, create lobes
using an IPC or a cone-shaped instrument.
(Figs. 7-13)

Figs. 10-12: Press the template with the translucent composite in it with the uncured composite
that is on the tooth, then cure. Natural result with incisal translucency.

Conclusion
Dentists need to be open-minded to
new techniques while preserving the tooth
structure, use common sense and rely on
evidence-based dentistry. With new product
developments and advanced contemporary
composites, it's possible to create predictable
natural results every time while only using
one or two shades of composite. ■
