| مستخلص: | Purpose: This study aimed to propose and evaluate standardised polishing protocols for in vitro experiment using a custom-made apparatus under controlled force to create consistent surface roughness on titanium and zirconia disks. Methods: A total of 160 discs were manufactured with a diameter of 10mm, 80 titanium (Ti), and 80 zirconium oxide (Zr). Specimens were categorised into 2 groups: controlled force (CF) and without controlled force (WCF). Specimens in the CF group were polished with a custom apparatus incorporating a tension gauge on the Ti and Zr disc surfaces to achieve consistent roughness. The WCF was polished without the use of a tension gauge. Each group had 4 subgroups (10 disks in each): control/machined (C) with no polishing, rough (R), smooth (S) and very smooth (VS). The subgroups were processed using a sequence of diamond-impregnated polishing burs and polishing paste. Results: CF group showed consistent surface roughness and a gradual decrease in surface roughness. Control (Ra=6.5±0.03µm) in Ti and (Ra=5.4±0.04µm) in Zr; R (Ra=3.5± 0.06µm) in Ti and (Ra=3.2± 0.07 µm) in Zr; S (Ra=1.5±0.04µm) in Ti and (Ra=1.1±006µm) in Zr; VS (Ra=0.05± 0.002µm) in Ti and (Ra=0.02±0.005µm) in Zr. There were significant differences for R, S, and SV under CF and WCF in Ti and Zr surfaces. Conclusion: The specimens polished under control force produced significantly more uniform surface roughness than those polished without controlled force and were produced with a higher degree of consistency. |
