Dr. Arthur R. Volker's CE course
" Injection Molding: Engineering
Composite Success " explains how to use
create Class II restorations, close black
triangles and create mirrorlike finishes
and invisible margins. It's available 24/7

Using a diamond football bur, the matrix band
was trimmed from the facial following the scallop
of the gingival tissue, leaving 3-4 mm of the matrix
coronal to the tissue. This is an essential step to the
protocol, because it will help the heated compule
achieve backpressure for injection molding and will
allow adequate light-curing of the material (Fig. 6).
Next, the tooth surface was etched with 35%
Fig. 9
phosphoric acid to create microscopic roughness on
the enamel and dentin, facilitating micromechanical
retention of the bonding agent (Fig. 7). Two applications
of a fifth-generation bonding agent (Prime
& Bond NT, Dentsply) were applied and light-cured
after air-thinning (Fig. 8).
A heated flowable composite (Filtek Supreme
Fig. 10
Ultra Flowable, 3M) was placed in the most apical
aspect of the matrix without curing (Fig. 9). Subsequently,
a heated paste composite (A2B, Filtek
Supreme Ultra, 3M) was applied (Fig. 10). Excess
composite was removed with a microbrush (Fig. 11).
It is important to remove the flowable and paste
composite before curing to facilitate removal of the
matrix band and simplify shaping. The composite
was then polymerized (Fig. 12).
The matrix band was removed and the restoration
received additional light-curing from multiple
angles. A final cure was performed under a DeOx gel
