Introduction: Y-TZP Zirconia is a ceramic used for dental implants because it has good biocompatibility and aesthet- ic properties, and it is affordable. Y-TZP formed from powder using uniaxial pressing with some added binder. The binders used are PVA, PEG and a combination of both. This combination reduce hardness and improve plasticity properties. Significantly increasing of the binder concentration and the surface roughness of the implant increases the porosity of the material as a place for the osseointegration process. Thus, the purpose of this study was to exam- ine the different effect of PVA-PEG binders on the surface roughness of Y-TZP zirconia. Methods: Twelve samples were divided into three treatment groups: 100% PVA, 100% PEG and 4% PVA-PEG added to Y-TZP powder at a ratio of 95:5 (wt.%). The mixture was pressed using a uniaxial pressing machine, sintered and measured: the data was then analyzed using one-way ANOVA and Post Hoc LSD. Results: The result of the ANOVA showed that there were significant differences in the surface roughness of the Y-TZP with three different binders (P<0.05). The average surface roughness of the three binders are as follows: PVA 100% (0.8025±0.23472), PEG 100% (1.2325±0.23866), 4% of PVA-PEG (1.3450±0.27695). The LSD showed that there was significant differences between PVA 100% and PEG 100% (P<0.05), PVA 100% and 4% PVA-PEG (P<0.05). There was no significant difference between PEG 100% and 4% PVA-PEG (P>0.05). Conclusion: 4% PVA-PEG binders combination has effects on the surface roughness of Y-TZP zirconia
