Figure 32: Next, we syringe an initial layer of<br />

Vertise Flow into the preparation. As shown<br />

here, this composite contains a self-etching<br />

bonding agent that is activated by using a<br />

disposable brush to burnish the material into<br />

the dentin for 20 seconds. In reality, you end up<br />

removing most of the first layer from the prep<br />

while doing this, but the point is to get a very<br />

thin layer in close contact with the dentin.<br />

Figure 33: Here we are light-curing the initial<br />

layer of Vertise Flow for 20 seconds. The light<br />

curing actually stops the self-etching of the<br />

dentin that was taking place. Now that we have<br />

that layer bonded to the dentin, we can add 2<br />

mm layers of Vertise Flow, curing for 20 seconds<br />

between each increment. As we are just bonding<br />

composite to composite at this point, there is<br />

no need to use the brush or agitate the material<br />

any more. The process simply is to add some<br />

material, light cure and repeat. Most flowables<br />

won’t support their own weight, so you are<br />

better off placing them in smaller increments.<br />

Figure 34: I always slightly overbuild these<br />

types of small build-ups, or fillers. I want to be<br />

able to prep it back flush against the natural<br />

tooth, so that I don’t leave an undercut in the<br />

tooth. We receive far too many maxillary anterior<br />

impressions at the lab with multiple undercuts<br />

in the teeth where direct composites used to<br />

be. Not only does this cause the impression to<br />

distort, but it also creates weakened dies. It is<br />

my hope that a simplified build-up technique<br />

like this one with Vertise Flow will help more<br />

dentists invest the time needed to place and<br />

charge for these build-ups.<br />
