I 35 industry report _ composite resin I cosmeticdentistry 1_2010 composed demonstrated that the optical incisal edge effects described above were particularly eye-catching in this case. Moreover, the bluish- whitish line extended far into the interproximal area. The challenge was to create a highly aes- thetic restoration. We strove to achieve this by means of a slight reduction of the diastema and the application of opalescent effects. Following, I describe the way improved restorative results can be achieved if an opalescent material is also available (IPS Empress Direct Trans Opal, Ivoclar Vivadent). The incisal view of the teeth shows the undu- lating contour of the incisal edge (Fig. 2). As sec- ondary decay was diagnosed, the old fillings were completely removed (Figs. 3 & 4). A per- forated, one-sided diamond abrasive strip was used to bevel the preparation margin (Fig. 5). Thus, minimally invasive roughening and bevel- ling of the enamel surface were ensured in the equi-gingival cervical region. Following etching with phosphoric acid and conditioning with ExciTEbondingagent(IvoclarVivadent),amatrix band was placed (Fig. 6). The band was slid into the sulcus along the proximal tooth surface and secured with a transparent wedge from the palatal side (Fig. 7). The anaemic appearance of the surrounding gingiva indicated that non- traumatic compression of the tissue had been achieved. In the palatal view, the size-1 wedge is clearlyvisible.Owingtothepressureitexerts,the interdental space was slightly enlarged. The ma- trix band was secured once in an optimum posi- tion. Then the first layer of composite material (IPS Empress Direct Dentin Shade A3) was placed Fig. 4_Defects viewed from the vestibular aspect.
