28 I I industry report _ composite restorations cosmeticdentistry 3_2011 After having moulded the gingival “arch”, which outlined the gingival margin of the veneer, the proximal portions were moulded in a sim- ilar fashion. As each layer was thinned out, the different shades and shapes blended well into each other (Fig. 7). Once the mamelon-type in- crement had been placed in the centre, the dis- colouration was completely masked. The A1 Dentin shade was used in both the proximal and central areas. To copy the appearance of the adjacent teeth, a translucent opalescent material was applied along the incisal edge. Finally, the entire com- posite build-up was covered with a layer of IPS Empress Direct B1 Enamel as indicated in the layering scheme (Figs. 8–10). _Finishing In order to reproduce the morphology and anatomy of natural teeth closely, just as much effort should be applied in finishing the restora- tion as in layering it. Following polymerisation, attention was paid to creating an optimal surface texture. First, the restoration was pre-contoured with fine-grit burs to remove possible composite excess. Fine-grit instruments provided the ad- vantage of allowing an optimal shape to be achieved in a controlled fashion. Moreover, the inadvertent creation of undesirable retentions or depressions was avoided. After pre-contouring the restoration, finishing and polishing were performed using the Astropol system (Ivoclar Vivadent; Fig. 11). _Conclusion With state-of-the-art composites such as IPS Empress Direct, natural-looking restorations can be created. Easy-to-use materials in combi- nation with individual layering schemes enable the employment of minimally invasive treat- ment procedures, even in cases in which indirect restorations would normally be indicated. By selecting a suitable restorative and following the treatment protocol described in this article, the three pillars of aesthetics can be taken in- to account in the restoration of anterior teeth (Figs. 12 & 13)._ Fig. 10_Application of the enamel layer (B1 Enamel).
