Mechanical changes of sandblasted Ti-6al-4v using 100 μm Al2O3 after dynamic pressure treatment: In vitro study

Background: Implant materials have been developed in such a way to fulfill various requirements of mechanical properties, one of the methods to change mechanical properties of implant is the sandblasting method. Purpose: This study aimed to determine the changes in mechanical properties of Titanium 6 Alloy 4 Vanadium (Ti-6Al-4V) sandblasted using 100μm Al2O3 after dynamic stress treatment. Method: 32 Ti-6Al-4V implant samples divided into two groups, 16 samples of treatment group (PI) and 16 samples of control group (PII). The PI group is Ti-6Al-4V sandblasted by Al2O3 100 and the PII group is Ti-6Al-4V machined surface. Both groups of samples were given dynamic treatment as much as 2 million times and then performed a compression test. Results: The results of data analysis showed PII> PI and there was a significant difference (p<0.05) between the PI and PII groups. Conclusion: In conclusion, there's difference in mechanical properties of sandblasted Ti-6Al-4V using 100μm Al2O3 after dynamic pressure treatment.
