case_images: It was observed that the metal cores of the anterior maxillary incisors were properly adapted and all the restored teeth had a satisfactory preparation design (Figure 2).

case_images: The soft tissue displacement was performed with gingival retraction cords (Ultrapak, Ultradent Products Inc., South Jordan, Utah, USA) because the patient gingival biotype showed a satisfactory thickness (Figure 3), minimizing the risks of irreversible gingival recessions.

case_images: After the all-ceramic restorations were finalized (Figure 9), their inner surface was etched with 10% hydrofluoride acid gel (Dentsply, Petropolis, Rio de Janeiro, Brazil) for 20 seconds according to the manufacturer's instructions (Figure 10).

case_images: Next, silane was applied on the etched surface for 60 seconds (Figure 11); then its excess was removed by air jets, so the restorations were prepared for cementation step.
