“…This coincides with the findings of Mittal et al (2016), who found that the tensile bonding strength was greater between silicone-based soft liner and high impact acrylic than that with conventional acrylic. (6) For both acrylic materials, plasma treatment showed a non-significant change on microhardness, which coincides with the conclusion of Dos Santos et al (2016), that there was no effect on microhardness of acrylic denture resin when treated with plasma, making it an acceptable method for surface modification when compared to other treatments. (23) The results of FTIR analysis may provide an explanation for preservation of microhardness.…”

“…(5) Soft liners serve in restoring the fit of the denture base in a variety of other clinical situations, including dentures that oppose natural dentition, xerostomia, and bony undercuts. (6) However, they suffer from a serious shortcoming, which is their debonding from the denture base following prolonged use, which may create a favorable environment for the growth of bacteria, thereby speeding up the decomposition of the material. (7,8) Various methods of surface modification have been tested out to overcome the problem of debonding between acrylic resins and soft liners.…”

Background: The main drawback of soft lining materials was that they debonded from the denture base after a certain period of usage. Therefore, the purpose of this research was to determine the impact of oxygen and argon plasma treatment on the shear bonding strength of soft liners to two different kinds of denture base materials: conventional acrylic resin and high impact acrylic resin. Materials and Methods: Heat cure conventional and high impact acrylic blocks (40 for each group) were prepared. A soft liner connected the final test specimen of two blocks of each acrylic material. Shear bond strength (SBS) was assessed using universal testing machine. Additional blocks were also prepared for analyzing Vickers microhardness, contact angle, FTIR and AFM. The results were statistically analyzed using paired-sample T-test and independent-samples T-test (α=0.05). Results: The results showed a highly significant increase in SBS following plasma treatment with the highest mean value observed in plasma treated high impact acrylic specimen. Along with a significant rise in wettability, while microhardness was preserved. Conclusion: In conclusion, oxygen and argon plasma treatment was significantly effective in enhancing the SBS between soft liner and acrylic materials.

Background: Clinically, adhesion failure is the most critical problem because of the failure of the optimal bond between denture base and the soft liner. Objectives: This study was performed to assess the tensile bond strength of two temporary soft liners to different denture base resins. Materials and Methods: Forty-eight blocks with 16 samples each of heat-cured denture base resin of three different types were fabricated from custom-made stainless steel die after de-waxing mold space. Surface roughening of each acrylic resin specimens which bonds with soft liners was done by abrading the surface and to this temporary soft liners (Perma soft denture liner and Pro soft denture liner) were bonded. The universal testing machine was used to test the tensile strength of bonded space. The results were statistically analyzed using the Statistical Software IBM SPSS Statistics for Windows, version 20.0. (Armonk, NY, USA: IBM Corp.) using the Chi-square test, Post hoc Tukey's HSD, and two way ANOVA tests. Results: It was observed that Perma soft was prevalent over Pro-soft denture liner on the basis of tensile bond strength with all three different types of denture base resins. Trevalon HI and acrylic composite exhibited better bond strength results with both Perma soft and GC Pro-soft denture liner as compared to other types of denture base resins. Conclusion: Perma soft had a better bond strength compared to Pro-soft denture liner in bonding modified denture base and conventional resins.

“…One of the serious problems is the failure of adhesion between the soft liner and the denture base. Therefore, measurement of bond strength is very important (Mutluay and Ruyter, 2005), (Mittal et al, 2016).…”
