Özet
Background The objective of this study was to assess the effects of surface finishing procedure, 3D printer type, and accelerated UV-aging on the surface roughness (Ra), translucency parameter (TP00), and color change (Delta E-00) of a 3D-printed permanent photopolymer resin. Methods Specimens (1 mm thick and A2 color) were fabricated using a permanent photopolymer resin and three 3D printers (Prusa Medical One, Form4B, and Asiga Max UV). Two surface finishing procedures (mechanical polishing and glazing) were applied to the specimen surfaces. UV-aging was applied using repeated cycles of light exposure and water spray at controlled temperatures for a total of 300 h. The Ra values and color coordinates were measured before and after accelerated UV-aging. The TP(00 )and Delta E(00 )values were calculated. The Delta E(00 )data were analyzed using two-way ANOVA, and the Ra and TP(00 )data were analyzed using three-way repeated-measures ANOVA. Pairwise comparisons were performed using Bonferroni adjustment (alpha = 0.05). Results Surface roughness (Ra) was significantly influenced by the printer type, surface finishing procedure, and aging (P < 0.05). Mechanically polished groups showed higher Ra values, although all remained below the clinical threshold. TP(00 )values were affected by the printer type, surface finishing procedure, and UV-aging; mechanically polished specimens showed higher TP(00 )values and minor aging-related differences than glazed specimens in Medical One and Form4B groups. Delta E(00 )was influenced by both printer type and surface finishing, with all groups exhibiting Delta E(00 )values above the clinical acceptability threshold. However, the glazed Form4B group showed the smallest color change, indicating greater color stability. Conclusions The surface finishing procedure, 3D printer type, and accelerated UV-aging significantly influence the surface and optical properties of the tested 3D-printable permanent photopolymer resin.
