The Impact of Brushing Simulation on the Surface Roughness and Color Changes of Coated 3D-Printed Temporary Crown Resin Material

Objective: to assess the surface roughness and color stability of coated 3d printed temporary crown resin material before and after brushing simulation.Materials and methods: 3D printed nano filled ceramic specimens have been printed using Asiga printer in the following dimension (10mm diameter and 2mm in thickness). The Optiglaze material was used for the tested specimens. The study has two main different group, first group control and the second group is the coated group. Surface roughness and color change was assessed before and after brushing simulation. All data were analysed using one-way anovaStatplus software.Result: Although there was a significant reduction in surface roughness compared to the control group, no notable differences were observed within the groups themselves. Brushing did not affect the surface condition in either group, and no noticeable color changes were detected in either the control or coated samples.Conclusion: The recent study suggests applying a glaze layer to temporary crown materials to enhance their surface characteristics.<br>
