Abstract

Purpose: To evaluate the influence of diode and Nd:YAG laser irradiations on the shear bond strength (SBS) between soft liner and different denture base materials.
Materials and Methods: 72 specimens (10x10x3mm) were prepared from CAD/CAM milled (IvoCad), 3D-printed (NextDent), polyamide (Flexi Ultra), and PMMA (Acrostone) (n=18 each). Each group was subdivided into 3 groups (n= 6) according to the surface irradiation: no surface irradiation (C), diode laser (L1) and Nd:YAG laser (L2). All specimens were bonded to soft relining material (Acrostone Soft relining). SBS test was performed using a Universal Testing Machine (UTM). Modes of failure were analyzed using a scanning electron microscope (SEM). Data was analyzed with Kolmogorov-Smirnov and Shapiro–Wilk, ANOVA, and post hoc Tukey, with a significant level set at 0.05.
Results: PMMA showed the highest significant SBS (0.807 ± 0.038), followed by IvoCad (0.477 ± 0.084), and the least significant SBS were shown with Flexi Ultra (0.326 ± 0.0.094) and NextDent (0.0.326±0.155). Insignificant changes were observed in IvoCad specimens by both L1 and L2 (p =1.000, 0.933 respectively). A mixed failure mode dominated all groups, except in PMMA (L1 and L2) subgroups, where a cohesive failure was observed, while adhesive failure was observed in Flexi Ultra and Nextdent (C and L1) subgroups.
Conclusions: Laser irradiation improved the SBS of 3D-printed denture resins, thermoplastic polyamide-nylon, and PMMA, while the milled resin was unaffected.
