Sažetak
Aim of this study was to evaluate surface roughness of Cerec 2 ceramic inlays after polishing with four different techniques. Twenty ceramic inlays were fabricated using Cerec 2 CAD/CIM method (Siemens AG, Germany) from the Cerec VITA MARK II ceramic blocs (Vita Zahnfabrik, Germany) and cemented on prepared extracted teeth. Inlays were divided in four groups of 5 specimens and polished with four different techniques: 1. Sof-lex discs (3M, USA) ; 2. Hawe brushes (Hawe Neos Dental, Switzerland) ; 3. Hawe brushes and diamond paste Diabrill (Oralia Dental GmbH, Germany) and 4. Rubber cups (Vivadent Liechtenstein). Roughness examination was performed with Perthometer Perthen S8P 4.5 (Feinprüf Perthen GmbH, Germany). Statistical analysis was performed using ANOVA with Tukey HSD test. Results revealed significant statistical difference for Rz, Ra, Rk, Rpk values for Sof-lex discs (Rz= 2.89ľm ; Ra=0.50ľm ; Rk=1.38ľm ; Rpk=0.445ľm). Also Ra values revealed significant differences for rubber cups with diamond paste vs Hawe brushes (Ra=1.11ľm). Rvk values for all techniques were not statistically significant (Rvk 1=1.137 m ; Rvk 2=2.37 m ; Rvk 3=2.40 m ; Rvk 4=1.948). It could be concluded that smallest surface roughness was achieved with Sof-lex discs polishing system. All other methods are clinically acceptable.
