Abstract

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.

To assess the tensile strength of tantalum oxide nanoparticles when used with 3D-printed denture-based resins before and after thermocycling.

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.

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).

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.
