case_images: A layer of flowable bulk-fill resin (SureFil SDR flow, DENTSPLY, Konstanz, Germany) was then applied at the base surface of both tooth preparations in single-layer increments until the dentin was completely full, leaving sufficient space (approximately 1 mm) to apply an enamel resin material (Figure 4).
case_images: Vestibular wall of tooth 36 has been restored with a layer of conventional high-refractive-index resin (UE1, Micerium S.P.A., Avegno, GE, Italy).

case_images: To complete the occlusal morphology of both teeth, a conventional stratification resin was selected (UE1, ENA HRi, Micerium S.P.A., Avegno, GE, Italy) that was applied in single-layer increments to complete the final anatomy of the lost enamel, after which it was light-cured for 40 sec (Figures 5 and 6).
case_images: The complete enamel has been restored with a conventional composite resin. Notice the correct anatomy achieved in both teeth.
