“…These materials are classified as resin-based soft liner and silicone-based soft liner 3 and are composed by monomers and polymers associated with plasticizers 5,6 which provide softness to the relining material and comfort to the patient 7 . Despite this advantage, the failure on adhesion of resilient liners to denture bases is one of the most common problems in clinical practice 1,8,9 . This failure is related to several factors: the non-use of primer, the mechanical properties of acrylic resin 9,10 and relining materials, and the aging of relining materials, which are in a constant contact with saliva, water, and changes in temperature due to feeding 8 .…”

“…However, this increasing did not lead to statistical differences between groups. The authors assume that this fact probably occurred because of the conditioning effect on PMMA acrylic resin surface promoted by the solvents present in the primer composition, as Can et al 8 affirmed, facilitating the bonding of the resin-based soft liner to the PMMA acrylic resin. According to Mutluay et al 13 , the solvents increase the surface wettability, promote the cleaning of the surface, and dissolve unattached particles of PMMA acrylic resin surface.…”

Purpose:The aim of this study was to evaluate the effect of a surface treatment with Sofreliner primer on tensile bond strength of a resin-based soft liner (Coe-Soft) bonded to a polymethylmethacrylate (PMMA) resin before and after accelerated aging simulated by a thermocycling machine. Material and Methods: One hundred and twenty rectangular specimens of PMMA resin were fabricated with 10 × 10 mm² of cross-section and 40 mm of height. The resin-based soft liner was positioned between two PMMA resin specimens. The specimens were divided randomly into 6 groups (n = 10) according to the surface treatment and accelerated aging cycles (0, 500 and 1000). After accelerated aging, specimens were submitted to tensile bond strength test. The fractures were classified as adhesive, cohesive or both. Results: Most failures were classified as cohesive (p = 0.025) and there was an increase on the mean values of tensile bond strength for group with primer application regardless the cycles of accelerated aging, and also an increase along thermocycling periods. The scanning electronic microscopy was used to illustrate the types of failures and the effect of primer application on PMMA acrylic resin surface. Conclusion: The primer application associated with resin-based soft liners is clinically viable, once this treatment strategy provides a reliable adhesion.

“…Commonly used silicone liners can be RTV and heat cured. 6 Soft liners have several problems like loss or varying degree of softness, colonization with Candida albicans, staining, porosity, poor tear strength and lack of color stability. 7 One of the serious problems is the failure of adhesion between the soft liner and the denture base.…”

“…Silicon‐based relining materials present little or no chemical adhesion to acrylic resin since these materials possess different chemical natures. Thus, primers compatible with acrylic resin and silicone are commonly used . In the present study, the Sofreliner Primer group, the manufacturer's recommended treatment, presented greater adhesion after the storage in saline solution (Table ).…”

Purpose To investigate the influence of nonthermal plasma (NTP) treatment on the tensile bond strength between heat‐polymerized acrylic resin for ocular prostheses and silicone reliner, with and without the use of an adhesive primer. Materials and Methods One‐hundred and sixty‐four acrylic resin specimens were fabricated and randomly distributed into four groups according to the type of surface treatment: Sofreliner Primer, NTP, Sofreliner Primer + NTP, and NTP + Sofreliner Primer. Two specimens interposed with relining material (Sofreliner) formed one test sample to perform the tensile bond strength tests, before (initial) and after storage (final) in saline solution (37°C, 90 days, n = 10). Surface characterization was performed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The failure type was classified as cohesive, adhesive, or mixed. The data were analyzed statistically using the two‐way ANOVA and Tukey test, as well as the chi‐squared test (α = 0.05), Bonferroni correction (α = 0.005), and Spearman correlation coefficient (α = 0.05). Results The SEM and EDS analyses showed the presence of a thin, homogenous organic film in the groups treated with NTP. The NTP + Sofreliner Primer group presented the largest bond strength mean values in the initial period (p < 0.05). Sofreliner Primer and NTP + Sofreliner Primer groups presented the first and second largest tensile bond strength mean values in the final period (p < 0.05), respectively. NTP + Sofreliner Primer group also had the largest number of cohesive (70%, initial) and mixed (90%, final) failures. Conclusions The NTP treatment performed before the primer application enhanced the bond between the acrylic resin ocular prosthesis and the Sofreliner silicone‐based reliner, even after 90 days of immersion in saline solution.
