Fig. 01 The patient presented with a failing composite restoration on tooth No. 13 and primary caries on tooth No. 12.

Fig. 02 Restoration removal and caries excavation were performed on both teeth.

Fig. 03 A single-component adhesive (Adhese Universal) was scrubbed into the tooth surface for at least 20 seconds to tooth No. 12.

Fig. 04 The adhesive was light cured with a LED curing light (Bluephase Style) for 10 seconds.

Fig. 05 A direct composite (Tetric EvoFlow A2) was placed in the preparation.

Fig. 06 The composite material was contoured

Fig. 07 Approximal polishing with Sof-Lex Discs (3M ESPE) was performed.

Fig. 08 A sectional matrix system was placed to isolated tooth No. 13.

Fig. 09 The enamel preparation of tooth No. 13 was etched for 15 seconds.

Fig. 10 The entire cavity preparation was etched for an additional 15 seconds.

Fig. 11 The etchant was rinsed and the tooth air dried.

Fig. 12 Adhese Universal was scrubbed into the mesial cavity of tooth No. 13 for at least 20 seconds.

Fig. 13 Adhese Universal was scrubbed into the distal cavity of tooth No. 13 for at least 20 seconds.

Fig. 14 The adhesive was dispersed with air until a glossy, immobile film layer resulted.

Fig. 15 The adhesive was light cured for 10 seconds.

Fig. 16 A flowable composite (Tetric EvoFlow A2) was applied to the preparation.

Fig. 17 A nano-hybrid composite material in shade A3 Dentin (IPS Empress Direct) was placed .

Fig. 18 The composite material was sculpted and contoured.

Fig. 19 Composite material in shade A2 Enamel (IPS Empress Direct) was applied to the preparation.

Fig. 20 The marginal ridges of tooth No. 13 were mesial and distal sculpted.

Fig. 21 The matrix was removed.

Fig. 22 Another layer of the composite in shade A2 Enamel (IPS Empress Direct) was placed to shape the occlusal area

Fig. 23 A contouring instrument (OptraSculpt Pad) was used to shape the composite material.

Fig. 24 Empress Direct Color in shades ochre and brown was applied to enhance the natural appearance of the restoration.

Fig. 25 The restoration was pre-polished with a polishing system (Astropol F).

Fig. 26 The restoration was then polished approximal with Sof-Lex Discs.

Fig. 27 Clinical situation before removing the rubber dam.

Fig. 28 The occlusion was checked.

Fig. 29 Adjustments were made to correct the patient’s occlusion.

Fig. 30 The restoration was finally high-gloss polished with an additional polishing system (OptraPol Next Generation).

Fig. 31 The restoration was finally high-gloss polished with an additional polishing system (Astrobrush).

Fig. 32 The occlusion was verified.
