Table 1

Conditioning sequences for tooth and restoration surfaces.

Composite veneers pretreatment
1	Sandblasting with 50 micron aluminum oxide particles (2.8 bar, 10 s, 1 cm)
2	Ultrasonic bath in ethanol (5 min)
3	Silane coupling agent application and evaporation (1 min)
4	Adhesive application (no photopolymerization)
5	Preheated resin composite application on the inner surface of the veneer
Enamel surface pretreatment
1	Pumice cleaning of teeth surfaces
2	Rinsing with water (1 min)
3	Application of Mylar strips around teeth to be conditioned
4	Phosphoric acid (38%) etching of enamel (30 s)
5	Rinsing with water (1 min)
6	Adhesive application (no photopolymerization)
