agent (Prime & Bond NT from Dentsply
Caulk) was applied on the mesial contact area
and halfway across the facial surface, then
light-cured (Fig. 7). Shade EA1 was added
to the mesial-facial (Fig. 8), built out to the
anticipated width of 8.46mm and contoured on
the facial with a gold Almore instrument and
smoothed with a #3 artist's brush (Tokuyama
Dental America) wetted with modeling resin
(Bisco). The restoration was then light-cured
for 20 seconds with an LED curing light (Valo
from Ultradent).
Estelite Omega was then added to the
lingual area of #9 and light-cured. The
width of #9 was checked with the digital
caliper and found to be slightly wider than
the 8.46mm ideal width. The large coarse
disc and finishing strips were used to obtain
the ideal width (Fig. 9) and generate a high
polish. The patient was moved to the upright
position and the midline was evaluated to be
completely straight up and down, preventing
the final restorations from having a midline
cant. The smooth surface and high polish on
the mesial of #9 will prevent composite from
#8 sticking to the restoration.7
Tef lon tape was then placed on the
restored tooth. Tooth #8 was acid-etched,
rinsed and coated with a bonding agent, as
was previously done to tooth #9. Estelite
Omega was added to the mesial-facial of
#8, then sculpted to match the contour of
#9. A slight space was left between the teeth
(space of a thin IPC) and then light-cured.
A clear Mylar/plastic strip was placed
between the teeth and composite was added
to the lingual of tooth #8. This composite
material was then sculpted into the contact
area with excess left on the lingual. The Mylar
strip was then pulled through to the facial.
There was a slight excess of composite on
the facial, which was then contoured with
a thin IPC (Cosmedent). The composite on
the lingual was sculpted so that the contact
area was even. The facial, lingual, incisal
and gingival embrasures were contoured
to have an even and symmetrical contact

area. The restoration was then light-cured
(Figs. 10-13, p. 68).
Observation of the teeth from the
occlusal view was essential to evaluate
facial contours and embrasures. A series of
Sof-Lex discs were used to create an even
and highly polished surface. Care was taken
to have the proximal line angles even and
well defined. The secondary anatomy was
created by the development depressions on
the facial surface. Drawing the proximal line
angles and a line in the middle of the tooth
