Figure 1: A 20-year-old patient presented for dental treatment
for aesthetic reasons due to a diastema between his maxillary
central incisors.

Figure 2: The intraoral view shows the positions of the anterior
teeth and their morphology in more detail.

Figure 3: We established that the four maxillary incisors would
need to be treated if we were to achieve a satisfactory result.

Figure 4: As a treatment method, we selected the production of
indirect restorations on a silicone model. This has advantages over
the use of prefabricated facets, as producing them in-house allows
for customisation and achievement of a better marginal seal.

such as the low relative cost, the possibility of personalising
the tooth shape, the reduced thickness of the cement layer
and the improved marginal seal.
The use of a mock-up, the basis for which was produced
in this case with Die Silicone (Voco) (Figure 4), is
advantageous for the simple and quick fabrication of indirect
restorations. The corresponding shade for the restorative was
selected right in the first treatment session.
This was done by applying a small quantity of each of the
possible shades to the vestibular surface of one of the teeth
to be restored and curing it. After comparing the shades, we
decided on A1 (Figure 5).

therefore to lengthen the maxillary incisors.
Light-curing was followed by finishing and polishing with
rubber polishers (Figure 7). We then photographed the
model and superimposed the image with a photo of the
patient smiling in order to check whether the size and
alignment of the teeth had been successful (Figures 8 and
9).
The veneers were adapted directly to the patient's teeth
(Figures 10-13). A considerable advantage of this technique
is the possibility of checking whether the result will satisfy the
expectations before the treatment is completed. Trying in the
restorations also allows the patient to see the result and
request any changes to be made.
Once the marginal seal had been checked and the patient
was happy with the aesthetics achieved, preparations were
made for placing the indirect veneers. We chose the
adhesive Futurabond U (Voco) in combination with the
flowable composite Grandioso Flow (Voco) in shade A1 for
the luting.

Restoration
The restorative material was applied to the silicone model
with a metal spatula for production of the actual mock-up
and thus also for the veneers (Figure 6). During this step, it is
important to try to stick to the planning specifications
compiled based on the photo analysis. The aim was
