Improving Surface Properties of PEEK for Dental Applications by Using Piranha Solution

Background. “Polyetheretherketone (PEEK)” is a biocompatible, high-strength polymer that well-suited for use in dental applications due to its unique properties. However, achieving good adhesion between PEEK and hydrophilic materials such as adhesives or cement can be challenging. Also, this hydrophobicity may affect the of an implant material. Surface treatment conditioning often necessary improve surface The piranha solution choice explored purpose. Methods. disks 10 mm diameter 2 thickness were used study. Those samples divided into five groups (each group has samples). first control group, which no acid was used; second undergoes sulfuric treatment. remaining three treated with Piranha solution; each different concentration (1 : 3, 1 5, 7 hydrogen peroxide acid, respectively). period 60 s all groups. Wettability roughness tests done In statistical analysis, Shapiro–Wilk test check assumption normality determine significance among groups; one-way analysis variance employed. Subsequently, multiple comparisons, Tukey’s honestly significant difference post hoc performed. Results. showed higher wettability compared acid. Additionally, 3) resulted greater improvement lower 5 7), while highest roughness. Conclusion. results study suggest effective method improving characteristics applications, especially material, increase
