SMILE TRANSFORMATION WITH

LITHIUM DISILICATE VENEERS

SANAH SAYED

Anterior teeth are important contributors to a beautiful and youth-
ful smile. Developmental defects, demineralization and caries can
disturb the harmony and surface texture of these teeth in turn affect-
ing smile and confidence of a person. Here I present a case of a 32
year old female who showed demineralization, discrepancy of shade,
irregular surface texture and previously placed proximal composite
resin on her anterior maxillary teeth.
On examination, we noted in addition to the above mentioned
findings she also lacked anterior guidance though canine guidance
was satisfactory. Such cases should be planned from a functional and
aesthetic viewpoint in order to ensure the long term success of the
restorations without disturbing the rest of the teeth.
After a detailed consultation, photographs and study models it
was decided to treat the case with 6 minimally invasive lithium di sil- FIG 1
icate veneers to alter shape, shade and surface texture.
Digital planning was done using power point and DTS Pro. The
lab used the planning as a reference while designing the restorations
in Exocad. We wanted to give her slightly longer central incisors
keeping lateral incisors marginally shorter and delicate outlines to
match her personality and make the smile more youthful and
appealing.

DENTOFACIAL AESTHETICS
Inter pupillary line was used as a reference and inter incisal line was
drawn along the maxillary incisal edges to ascertain maxillary cant
(if any). In this case there was no cant and the patient had a good
profile. The incisal display and position were also satisfactory. Our
eyes are extremely sensitive to a maxillary cant and most patients
notice it as a longer central incisor compared to its adjacent incisor.
Dental midline and facial midline were a match in this case how- FIG 2
ever a discrepancy of upto 2 mm is unnoticed in most cases as long
as the midlines are parallel.
The dynamic smile was gummy showing a couple of mms how-
ever she did not mind it and with a week in hand we could not have
addressed it.

DENTAL AESTHETICS
Young Anterior teeth are bright with abundant surface texture
which helps the scattering of light further increasing the value of
these teeth. In this case, the teeth looked dull and dark contributing
to a visual distress of highly chromatic teeth. In addition the
