“…The bond between the prosthesis and liner begins with the dissolution of the resin by the solvent, swelling of surface layers, and evaporation of the solvent. The liner monomers diffuse, penetrate the resin pores, and form an interpenetrating polymeric network [51]. The larger the surface swelling, the deeper the porous layer and, as a consequence, the better the adhesion between the liner and denture base.…”

Purpose. The objective of this systematic review is to compare results concerning the properties of adhesion, roughness, and hardness of dental liners obtained in the last ten years. Methods. Searches on the databases LILACS, PubMed/Medline, Web of Science, and Cochrane Database of Systematic Reviews were supplemented with manual searches conducted between February and April of 2018. The inclusion criteria included experimental in vitro and in vivo, clinical, and laboratory studies on resilient and/or hard liners, assessment of hardness, roughness, and/or adhesion to the denture base, and physical/mechanical changes resulting from the disinfection process and changes in liners’ composition or application. Results. A total of 406 articles were identified and, from those, 44 are discussed. Twenty-four studies examined the bond strength, 13 surface roughness, and 19 the hardness. Of these 44 studies, 12 evaluated more than one property. Different substances were used in the attempt to improve adhesion. Considering roughness and hardness, the benefits of sealants have been tested, and the changes resulting from antimicrobial agents’ incorporation have been assessed. Conclusion. Adhesion to the prosthesis base is improved with surface treatments. Rough surfaces and changes in hardness compromise the material’s serviceability.

“…The results of the meta‐analysis indicated that for silicone‐based liners subjected to tensile test, chemical agents are more effective than the other surface treatments. While most of the reviewed literature reported that chemical agents were more effective than the other surface treatments, a few studies reported that it was ineffective or provided similar outcomes to other procedures . Gundogdu et al reported that chemical agents were more effective than sandblasting, laser, and control groups to increase tensile bond strength of silicone‐based resilient lining material to PMMA.…”

“…Sarac et al and Akin et al reported that CA increased the tensile bond strength of silicone‐based resilient lining material to PMMA. Osathananda and Wiwatwarrapan reported that in silicone‐based resilient lining material subjected to shear test, chemical agents were more effective than resilient lining chemicals, and in acrylic‐based resilient lining material, chemical agents were more effective than MMA. Chemical agents cause denture base resin irregularities that can facilitate mechanical locking of the resilient lining material, thereby improving the bond strength between the denture base and the resilient lining material …”

The efficacy of surface treatments varies depending on the resilient lining materials and the test type. More successful results can be achieved by selecting the appropriate surface treatment according to the type of the resilient lining material to increase the bond strength. In particular, when used alone, laser appears to be more effective. Chemical agents and laser are the most effective surface treatments for both silicone- and acrylic-based liners. Moreover, new studies are required to determine the efficacy of CoJet. These findings should help clinicians select a suitable surface treatment to increase the bond strength of resilient lining materials to denture base materials.

“…In addition, MMA, MF, and MA molecules have the methyl ester group, which increases their ability to soften PMMA 6. The MF, MA, and MF-MA mixture increased the bond strength of repaired acrylic denture base and acrylic denture base relined with rebasing material 78. Thus, it is hypothesized that MF-MA mixture would result in higher tensile bond strength between acrylic denture teeth and auto-polymerized acrylic resin compared with using MMA liquid.…”

“…In addition, other studies have been conducted for investigating the surface treatment of acrylic denture base and reline resin with methyl formate-methyl acetate (MF-MA). These studies have shown that MF-MA significantly enhanced the bond strength between acrylic denture base and reline resin 89…”

PURPOSEThis study evaluated the effect of chemical surface treatment using methyl formate-methyl acetate (MF-MA) solution on the tensile bond strength between acrylic denture teeth and auto-polymerized acrylic resin.MATERIALS AND METHODSSeventy maxillary central incisor acrylic denture teeth for each of three different brands (Yamahachi New Ace; Major Dent; Cosmo HXL) were embedded with incisal edge downwards in auto-polymerized resin in polyethylene pipes and ground with silicone carbide paper on their ridge lap surfaces. The teeth of each brand were divided into seven groups (n=10): no surface treatment (control group), MF-MA solution at a ratio of 25:75 (v/v) for 15 seconds, 30 seconds, 60 seconds, 120 seconds, 180 seconds, and MMA for 180 seconds. Auto-polymerized acrylic resin (Unifast Trad) was applied to the ground surface and polymerized in a pressure cooker. A tensile strength test was performed with a universal testing machine. Statistical analysis of the results was performed using two-way analysis of variance (ANOVA) and post-hoc Dunnett T3 test (α=.05).RESULTSThe surface treatment groups had significantly higher mean tensile bond strengths compared with the control group (P<.05) when compared within the same brand. Among the surface treatment groups of each brand, there were no significantly different tensile bond strengths between the MF-MA groups and the MMA 180 second group (P>.05), except for the Yamahachi New Ace MF-MA 180-second group (P<.05).CONCLUSION15-second MF-MA solution can be an alternative chemical surface treatment for repairing a denture base and rebonding acrylic denture teeth with auto-polymerized acrylic resin, for both conventional and cross-linked teeth.
