RESUMO

The surface characteristic of ceramic material is an important factor to predict its wear behavior. The surface roughness of two ceramics (Duceram Plus e Duceragold) was evaluated trough qualitative and quantitative methods after different treatments. 36 specimens were fabricated for the analysis utilizing a surface profiling instrument, and 24 for the SEM analysis. The results determined different behavior between the two ceramics evaluated due the treatment executed. The analysis utilizing a surface profiling instrument showed that the treatment using the EDENTA polishers was the most effective technique to provide the smoothest surface after trimming. All polishing techniques resulted in better surface properties when compared to the treatment glaze. The Duceragold ceramic presented lower roughness values in most treatments executed when compared to Duceram Plus. The perception trough the SEM analysis of significant differences between treatments or between the two ceramics was not achievable.
