| Abstract | Introduction: A 3D printing UDMA consists of different chemical compositions from hard relining materials.As a result, repairing or relining 3D printing UDMA denture base has been questioned in clinical practice. Objective:This study aimed to compare the shear bond strength between 3D printing UDMA denture base and PMMA denturebase material bond with hard relining materials. Materials and Methods: A total of forty denture base specimens,26 mm in diameter and 10 mm in thickness, were prepared for heat cured PMMA (Vertex?) and UDMA (Optiprint?).They were relined with Unifast trad and Tokuyama rebased II, then thermocycled (5 ?C / 55 ?C, 2 c/min) for 5,000cycles. A shear bond strength test (MPa) was performed on a universal testing machine. Data were statisticallyanalyzed using a two-way ANOVA analysis, followed by Post hoc Tukey's test (p < .05). Result: Two-way ANOVAshowed significant differences in the shear bond strength values (p < .05). In addition, Vertex? showed the highestshear bond strength value when relined with Unifast trad? (16.39 ? 3.22 MPa), followed by relined with Tokuyamarebase II? (7.81 ? 2.63 MPa). Optiprint? showed the lowest shear bond strength value when relined with Unifast trad?(4.63 ? 2.13 MPa). Conclusion: The two different denture base types have demonstrated that shear bond strengthvalues are corresponded to various relining materials. |
