Background: Advancements in dentistry and incorporating 3D printing techniques have numerous benefits over traditional methods. However, the produced resins have shown a lack of good biocompatibility and insufficient mechanical properties. Tantalum oxide, on the other hand, exhibits biocompatibility, excellent physical and mechanical properties, and an antimicrobial effect.
Aim of the study: To assess the tensile strength of tantalum oxide nanoparticles when used with 3D-printed denture-based resins before and after thermocycling.
Materials and Methods: The materials tested in this study were laser-based stereolithography (an additive manufacturing process, SLA). Eighty samples were prepared from 3D-printed resin. The sample was divided into two groups (before and after thermocycling), and each group was subdivided into four subgroups.
Results: There was a statistically significant association between the used concentrations when tested before and after thermocycling, with a high statistical significance (p-value = 0.001). Additionally, there was a high statistical significance for the concentration before thermocycling in relation to after thermocycling with (p-value 0.001).
Conclusion: Using tantalum oxide improved the tensile strength of the 3D-printed resins by promoting characteristic osseointegration and enhancing its ability to promote osteoblast formation, proliferation, and integration into the bone.
