Abstract

The dentistry field is in continuously developing, especially with three-dimensional (3D) printing technology. This study aims to analyze how resin 3D-printed denture bases affect the thermal conductivity, surface roughness, and surface hardness when carbon nanotubes (CNTs) are added at various weight percentages. 3D-printed denture base acrylic resin has been enhanced with CNTs. The samples were divided into three groups (0.5% and 0.7% of CNTs by weight, and a control group with no added CNTs). All samples underwent thermal conductivity, surface roughness, and surface hardness tests. In addition to conducting analyses using Fourier transforms, infrared spectroscopy, and field emission scanning electron microscopy, the data were analyzed using one-way analysis of variance (ANOVA) and multiple comparison tests. Incorporating CNTs into 3D-printed denture bases enhanced surface hardness, roughness, and heat conductivity compared to the control group. This improvement is directly correlated with the concentration of CNTs added. Integrating of CNTs enhances the material’s mechanical properties, specifically its thermal conductivity and surface hardness. However, it does not have a great impact on surface roughness. Therefore, caution must be taken when selecting the appropriate CNTs concentrations to be added to the 3D-printing resin to improve the material characteristics.
