Selecting the Right One-Shade Flowable

With OMNICHROMA, the single-shade family of composites, restorations will look esthetically pleasing, withstand the wear and tear of life, and look just as natural as the day of the restoration even after 6 months, 1 year, and longer.

I have been using Tokuyama Dental products for the past 14 years. In June 2018, I  began incorporating OMNICHROMA into my practice 8 months before it was publicly launched. Tokuyama’s team asked if I wanted to be one of the first to try its new composite and provide my honest opinion on OMNICHROMA’s handling and use. It was a great honor, as well as a nice surprise, to see how well the composite blended with the surrounding tooth structure. A few years later, Tokuyama introduced a flowable version of OMNICHROMA as well as the most recent addition, a flowable bulk fill.

When selecting restorative products, I like to check the handling, the working time, how easily the tooth can be finished and polished and, most importantly, the shade matching — how well it blends naturally with the tooth.

For this first case, a patient presented with a large and shallow Class I. After removing all the decay and prepping the tooth surface, I placed and light cured OMNICHROMA Flow (A). In the 6-month recall image (B), note how the tooth shade has held up perfectly, and the patient is extremely satisfied with the result.

For my second case, when deciding which flowable to use, I considered both the size and depth of the cavity preparation. For this deeper case, I chose OMNICHROMA Flow BULK. It has a lower viscosity and is a bit runnier with a 3.5 mm depth of cure in contrast to OMNICHROMA Flow’s standard 2 mm. Because this second case is much deeper, using a composite with a higher flow allowed me to get into all the nooks and crannies, and bulk-fill the entire area without worrying about voids or poor cavity adaptation (C and D).

I usually don’t need any special techniques to achieve excellent results with the OMNICHROMA flowables. However, I would recommend ensuring a clean and neat cavity preparation without leaving any superficial caries and stains that could interfere with the shade matching. By not fully cleaning the preparation, the composite may pick up the darkness or stain in the tooth and potentially drop in value. Luckily, Tokuyama thought of this possibility and created OMNICHROMA BLOCKER and OMNICHROMA BLOCKER Flow — a supplemental opaquing material that can be applied in a layer as thin as 0.5 mm to mask staining and block out any darkness.

Additionally, when using any of the OMNICHROMA composites, I like to create a wide bevel on the enamel surface so the composite can blend well with the existing enamel. Finally, I use a flame-shaped diamond bur to carve natural-looking occlusal anatomy.

My patients never leave my office without seeing before-and-after images of their restorations to ensure complete and total satisfaction. With the help of Tokuyama Dental’s family of OMNICHROMA flowable single-shade composites, I can guarantee just that!
