A time-saving workflow

Bulk fill composites have paved the way for new strategies in dental composite technology. The demand for systems that are ever easier to use and yet offer the same reliable properties continues to grow. Ivoclar Vivadent is now introducing a new bulk-fill composite in a flowable consistency that offers dentin-like translucency levels and allows applications in increments of up to 4 mm.

Given its flowable consistency, Tetric EvoFlow Bulk Fill facilitates the restoration procedure for Class I and Class II cavities and reduces chairtime. The new flowable bulk fill material follows the introduction of the mouldable Tetric EvoCeram Bulk Fill composite four years ago and enables dental professionals to improve the efficiency of their day-to-day restorative care without cutting corners on quality. 

In essence, Tetric EvoFlow Bulk Fill is based on the chemistry of Tetric EvoCeram Bulk Fill and, just like the latter, it can be cured in large single increments of up to 4 mm, while requiring only short light exposure times. These advantages are due to the Ivocerin light initiator, which Ivoclar Vivadent developed. As an additional advantage, Tetric EvoFlow Bulk Fill features a low, dentin-like translucency and, as a result, is capable of effectively masking dark discoloured dentin areas including amalgam stainings to provide light and natural-looking restorations. The material gains its dentin-like translucency from the Aessencio technology developed by Ivoclar Vivadent. With this technology, the apparent contradiction between high curing depth, short curing times and low translucency has been successfully resolved.

Tetric EvoFlow Bulk Fill is suitable for applications in Class I and II restorations and should be covered with a layer of load-bearing composite such as Tetric EvoCeram Bulk Fill. A covering layer is not required for restorations in deciduous teeth. Given its dentin-like translucency, the flowable Tetric EvoFlow Bulk Fill is the ideal companion for Tetric EvoCeram Bulk Fill, which features an enamel-like translucency. Shades IVA, IVB and IVW are ideally suited for combined applications with Tetric EvoCeram Bulk Fill.

First clinical case

In the course of a dental check-up, four carious lesions were detected underneath existing fillings in the first quadrant (Fig. 1). The patient preferred these lesions to be restored with a direct, minimally invasive procedure in a single appointment. Following the removal of the old filling materialand secondary caries, a rubber dam was applied and the enamel margins were prepared in such a fashion as to ensure optimum enamel adhesion. The intention was to use Tetric EvoFlow Bulk Fill to mask the stained areas, some of which were severely discoloured. Garrison Composi Tight and Composi Tight 3D XR matrix systems were placed. After etching the enamel with phosphoric acid (Total Etch) for 30 seconds and the dentin for 15 seconds, Adhese Universal was dispensed from a VivaPen, scrubbed into the tooth surface for 20 seconds and then dispersed with compressed air (Figs 3 and 4). Adhese Universal should be dispersed until motion of the adhesive layer can no longer be detected. Next, the adhesive was light-cured for 10 seconds using a Bluephase Style curing light.

After that, Tetric EvoFlow Bulk Fill IVA was applied into the cavity (Figs 6 and 7). In the process of being polymerized, the adhesive's translucency decreases to a dentin-like level, as can be seen in Figure 8. I applied a single increment of Tetric EvoCeram Bulk Fill to contour the occlusal relief. This allowed me to cover the flowable material and achieve a restoration that is occlusally stable (Fig. 9). Each increment was light-cured for 10 seconds.

The restorations were finished using diamond burs and polishing discs. After adjusting the occlusal height and removing mediotrusive interferences, I polished the restorations to a high gloss using OptraPol (Figs 10 and 11).

Second clinical case

In this case, too, Tetric EvoFlow Bulk Fill enabled me to attain natural-looking restorations. Three amalgam fillings were replaced with Tetric EvoFlow Bulk Fill IVA and Tetric EvoCeram Bulk Fill IVA (Figs 12 and 13). Again, the material's translucency decreases as it polymerizes (Figs 14 and 15). The effect of the Aessencio technology ensured that the amalgam stained areas were again successfully masked. As before, Tetric EvoCeram Bulk Fill wasused for the covering layer (Fig. 16).

Third clinical case

Especially convenient is the application of Tetric EvoFlow Bulk Fill after an endodontic treatment because it features self-levelling capabilities and a dentin-like translucency (Figs 17, 18 and 19). Substantial amounts of time can be saved due to the possibility of applying increments of up to 4-mm.

Conclusion

Deep cavities can be restored with only two increments if the flowable Tetric EvoFlow Bulk Fill is used in combination with the sculptable Tetric EvoCeram Bulk Fill. For the first time, dentin-like 4-mm-thick layers can be cured with short exposure times due to the Aessencio technology and the Ivocerin light initiator. Discoloured dentin areas can be reliably reconstructed to achieve an esthetic restoration using the materials from Ivoclar Vivadent's Bulk Fill portfolio. Tetric EvoFlow Bulk Fill is the ideal companion for Tetric EvoCeram Bulk Fill.
