“…21 Therefore, in clinical practice, the choice for an appropriate denture liner, especially long-term materials as well efficient chemical cleanser that does not interfere with the liner's properties is of paramount importance. 5 In this study results showed that immersion in water or soaking in cleansing solutions did not cause any significant changes between the differently processed soft liner specimens and also within the same soft liner (p > 0.05).…”

“…3 Dentures are used in an aqueous environment in the oral cavity and when not used, they are kept in water or in an aqueous cleansing solution. 4,5 When immersed in soaking solutions or placed in the oral cavity, soft denture liners undergo two processes: leaching out of plasticizers and other soluble materials, and sorption of water or salivary components. The fluctuation between these two processes affects the properties of the denture liner material.…”

This study aim to investigate the effect of denture cleansers and standblasting on tensile bond strength of soft denture liners after 3 and 6 mounths of immersion.For each of the liner materials, 70 test specimens were prepared according to test the requirements. Half of the 70 test specimens were sandblasted with 50 μm Al2O3 at 2 bar for 10 s. The resilient liner specimens were processed between 2 polymethyl methacrylate (PMMA) blocks. Before tensile testing, five of the liner specimens were kept in water or soaked in two cleansing solutions during 3 and 6 month. Bonding strength of the liners to PMMA was compared by tensile test with the use of universal testing machine at a crosshead speed of 50 mm/min. The mean value and standard deviation of the specimens were made by using a multifactorial analysis of variance (α=0.05). The type of failure was assessed visually.No significant difference was found between the groups for the tested conditions used (p>0.05). The most frequent failure mode was cohesive for Permaflex (P) specimens, adhesive for sandblasting groups, and a mixed type of failure was observed for GC Reline Soft (GC) material.The denture base cleaners affect the bond strength of PMMA/resilient liner. Permaflex and GC Reline Soft as resilient liners were found to have adequate adhesive values for clinical use.

This study aimed to evaluate the airborne-particle abrasion surface treatment effects on the tensile bond strength (TBS) between resilient denture liner and CAD/CAM or conventional heat polymerized poly (methyl methacrylate) (PMMA) acrylic denture resins. A total of 48 dumbbell-shaped specimens (70 mm in total length, and 12 mm and 7 mm in diameter at the thickest and thinnest section, respectively) were prepared from CAD/CAM and conventional acrylic resins. Before relining with denture liner, 12 specimens from each material were surface-treated by 110 µm Al2O3 airborne-particle abrasion, and the remaining specimens served as control (no treatment). Following relining, all the specimens were aged by thermal cycling (1000 cycles, 5–55 °C). The TBS of denture liner to acrylic denture resins was tested in a universal testing apparatus at a 5 mm/min crosshead speed. The debonded surfaces were visually examined for the failure modes. ANOVA and multiple comparisons posthoc analysis tests were applied to determine the significant difference in TBS between the study groups (α = 0.05). A significant difference in TBS was observed between the control and surface treated groups (p < 0.001) for both acrylic resins materials. However, there was no statistically significant difference in bond strength between the acrylic resins materials (p = 0.739). Surface treatment with airborne-particle abrasion demonstrated increased TBS of the soft denture liners to acrylic resins. The TBS of conventional and CAD/CAM acrylic resins to soft denture liners were not considerably different.
