Veneers
If possible, the preparation should be entirely located in the enamel,
either in the form of a simple incisal reduction without incisal over-
lap or conventional preparation with incisal, chamfer-type incisal
overlap. make sure that the incisal preparation margin is not located
in the area of the abrasion surfaces. the extent of the incisal reduc-
tion depends on the desired translucency of the incisal area to be
built up. the more transparent the incisal edge of the intended
veneer, the more pronounced the incisal reduction should be. the
incisal edge should be reduced by at least 1.0 mm. By preparing ori-
entation grooves using a depth marker, controlled enamel reduction
can be achieved. the minimum preparation thickness is approx.
0.6–1.0 mm, depending on the preparation technique selected.
Elimination of the proximal contacts is not required. discoloured
teeth may require more preparation. In the cervical area, prepare a
chamfer.
