And evaluate clinic in each restorations: permanency, stable, resistense abrasion and integration marginal. The result shows of the restoration with resin was a exict the 80% ¡n clase I, 60 % in clase II (OD-OM), and 55% in clase II (MOD). The restorations with amalgam was exict of'100% ¡n clase I, clase II (OD-OM) and 95% ¡n clase II (MOD). Was necessary Sustitution 4, the each 20 restorations with resin clase I; 8 of each 20 restorations with resin clase II (OD-OM) and 9 at 20 restorations with resin clase II (MOD) in compara-tion with restorations with amalgams clase I and clase II, was do not necesited of sustitution in the 100% of cases clinics treated. The restorations with resin in cavities small (Clase I) was to much duration significative, in comparative with restorations of resin in cavities extra large (clase II).
