Preparation of the aforementioned teeth was achieved with a <<pencil shape>> tip burr, wearing down 1 mm at all sides, and rounded borders. Restorations were adjusted, the tooth surface was etched for 15 seconds, and an adhesive layer was applied, polymerization was promoted during 10 seconds, and finally teeth were cemented with dual resin Figure 4. Restorations had previously been treated with hydrofluoric acid and silane application Figure 5.
