Etching step of the not-prepared enamel surface using 3M ESPE™ Scotchbond™ Universal Etchant for 20 seconds. It’s mandatory to protect the neighboring teeth to avoid the over etching. Matrix or teflon are good options to obtain an adequate isolation.

Bonding step: multiple layers (2-3) of the bonding agent ensure a great resin interdigitation into the etched enamel, which is also increased by a gentle air blow before the polymerization.

Final result. The finishing and polishing system is mandatory to improve the aesthetic, thus realizing a smooth and gloss surface. The use of one single layer of Filtek Universal Restorative leads to an aesthetic and functional restoration, meeting the expectations of both the clinician and the patient.



Conclusions



The finishing and polishing system is mandatory to improve the aesthetics and morphology roughness and gloss surface. The teeth present a good aesthetic, transitions lines and the secondary anatomy gives appreciable aesthetics.
