Objective: The implant material that is often used is Ti-6Al-4V (grade 5 titanium). One of the requirements for successful implant placement is osseointegration which is a structural and functional relationship between the bone and the implant surface. To improve the osseointegration of the implant, modifications can be made to the implant surface, one of which is sandblasting which serves to make the implant surface rough enough to increase mechanical interlocking which allows better cell attachment. But on the other hand, this technique can reduce the endurance of the implant so it increases the possibility of fracture of the implant. Aim: The aim of the study is to determine the changes in the properties of Ti-6Al-4V after being sandblasted with 50μm AL2O3. 16 Ti-6Al-4V implants that had been blasted with 50μm AL2O3 and 16 Ti-6Al-4V implants without sandblast were given dynamic treatment with a pressure of 100 N for 2 million times, with a frequency of 15 Hz and then tested with a compressive test. Result: There was a significant average difference between the two groups as indicated by the results in the group without surface treatment (1682 N) and in the group that was sandblasted with 50 μm Al2O3 (815 N). Conclusion: Sandblasting using 50μm Al2O3 can reduce the endurance of Ti-6Al-4V implants because microcracks left by Al2O3 on the implant surface can lead to fracture initiation.
