[Acid etching of prefabricated porcelain veneers].
The aim of the present work is to study on standard porcelain teeth the acid concentration to produce the micromechanic retention with the cemented resin and then to enamel. Teeth were beater-up following the described technique, the application of two different types of etch solutions: hydrochloric acid and fluorhidric acid, in a lack of application time between 10 to 20 minutes. With the purpose of determine the type of etch solution that produce the best amount of micropores in standed porcelain laminates veneers we can conclude that: to the internal etched of the standard porcelain laminates veneer, the utilization of fluorhidric acid is the most convenient, also is necessary the previons stand blaster with aluminum oxide of 25 um to increase the retentive capacity over the etch surface.
