Clinical Feature
1. Decay is noted on the distal surface
of the right mandibular 2 nd bicuspid
(Fig. 2).
2. The decay is accessed and removed
with the Great White #2 bur (SSWhite)
(Fig. 3).
3. The conservative cavity preparation
is complete. The tooth is matrixed
and subsequently wedged (Fig. 4).
4. The preparation is bonded with a 7 th
generation adhesive (Fig. 5).
5. The bonding agent is light-cured with
the Fusion 5 (Dentlight) (Fig. 6).
6. The cavity is restored with composite
resin as the interproximal contact is
made with the CCI (Contact Curing
Instrument, Hu-Friedy) (Fig. 7).
7. The occlusal surface is pre-shaped
with the “Duckhead” instrument
(Hu-Friedy) prior to curing of the
surface layer (Fig. 8).
8. Final surface polishing (Fig. 9).
9. The completed restoration
(Fig. 10). DA
