[Study of traction and effect of bonding agents on etched porcelain].

Abstract

Nowadays many authors suggest the use of porcelain laminate veneer that has come to play an important role in the solution of many esthetic and functional problems. At the moment, it is the alternative treatment to solve some cases with the least dental reduction, the highest fitting and a low cost. To evaluate the tractional resistance done on the porcelain veneer, in which acid etching and connecting agents were applied, I suggest: 1. The resistance of traction carried out on etched porcelain laminate to which an agent of silane join and a resin of connection were applied, was the one that had the best conduct. 2. The tractional resistance carried out on the laminate fronts where a treatment of only silane and resin of connection was applied, was greater where the treatment of silane was employed. 3. The etched with acid both in the adamantine surface and in that of well depurated porcelain, is an important factor to obtain a good retention.
