Abstract:
Background: Dental implant materials have been developed over time and become an alternative to dental treatment. One of the materials, Ti-6Al-4V, is widely used. The pH saliva in the oral cavity can change due to various factors, thereby affecting the implants durability. This research was conducted to determine the durability of Ti-6Al-4V implants based on their effect on the oral environment.
Objective: To analyze change of compressive strength of Ti-6Al-4V in artificial saliva pH 6.5 and dynamic stress treatment.
Material and Methods: Laboratory experimental and analytic research was conducted with 27 Ti-6Al-4V implant samples, which were classified into 3 groups, each consisting of 9 samples, including those with no treatment, aquades solution, and artificial saliva with pH of 6.5. In the negative control group, the samples were treated dynamically, while the samples in the positive control group were not treated. Samples from the treatment group were subjected to a dynamic test in accordance with ISO 14801 standards while being immersed in artificial saliva with pH of 6.5. Thereafter, a compression test was conducted on each group. A one-way ANOVA test was used to analyze the comparison of the results.
Results: The results of data analysis using One-Way ANOVA found a significance value of less than 0.05 (Sig<0.05). This shows that there is no significant difference between each group and the average maximum compression value was T1<T3<T2.
Conclusion: There were no significant changes in compressive strength of Ti-6Al-4V after immersion test with artificial saliva pH 6.5 and dynamic treatment.
