36 I I industry report _ composite resin and adapted in such a way that it created a pre- liminaryoutlineoftheproximalcontours(Fig.8). Subsequently, a further layer of composite was added (Fig. 9). This was followed by a layer of Dentin Shade A2 (Fig. 10), which served to optimise the shade adjustment. Next, a layer of Enamel Shade A2 (Fig. 11) was placed and the build-up was completed with Trans Opal. Figure 12 demonstrates the building up of the com- posite materials to create the final tooth shape, which also simplified morphological contouring during the finishing procedure. For finishing, an EVA tip handpiece was used. This handpiece per- forms oscillating movements. Owing to the fine tip, completely non-traumatic finishing was en- sured, particularly along the transition between the filling material and sulcus. The fine reduc- tion, which was achieved by means of suitable grit size (the green or blue ring is used for pre- polishing),enablestargetedfinishing.Therefore, over-contouring of the composite restoration was not necessary. The surface was finished exclusively with an EVA tip and subsequently polished with a pre-polisher and high-gloss polishers (Astropol, Ivoclar Vivadent). Polishing brushes (Astrobrush, Ivoclar Vivadent) were used to finish the surface with a final high-gloss sheen. In tooth 11, a matrix band was used to shape the proximal surface (Fig. 13). The band also served to protect tooth 21 from the etching gel that was applied immediately afterwards. The wedge was placed with tension in order to establish a perfect separation of the teeth. The intention was to reduce the diastema sub- stantially. The primary composite increments were applied according to the protocol des- cribed above. The final layers were also placed based on the previously mentioned criteria. Also, in this case, Trans Opal material was used to complete the build-up (Fig. 14). After polish- ing the restoration to a high lustre, a slight colour discrepancy due to the dryness of the superficial enamel portion was recognisable. The interdental papilla was still slightly com- pressed owing to the wedge (Fig. 15). The final photograph (Fig. 16), which was taken one week after placement of the restoration, shows a completely healthy papilla and virtually invisible composite restorations with lifelike opalescence._ Fig. 13_A matrix band has been inserted in the interdental space between teeth 11 and 21; etching gel has already been applied.
