Adhesion characteristics of visible light-cured denture base material bonded to resilient lining materials

Effect of storage duration on tensile bond strength of acrylic or silicone-based soft denture liners to a processed denture base polymer

“…The present results are in agreement with those of others [7,9,20] who suggested that water storage reduced soft liner bond strength. A decrease in bond strength may result from swelling and stress built up at the bond interface, or of a change in the viscoelastic properties of the liner, rendering the material stiffer and thus better able to transmit external loads to the bond site.…”

Comparison of bond strength of auto polymerizing, heat cure soft denture liners with denture base resin — An In Vitro study

“…The result of bonding of Molloplast-B soft liner against un-polymerized denture base resin was in accordance with the study conducted by Amin et al (1981) [12] and Jagger (2002) [13]. It has been reported by Craig (1961) [14] and Khan et al (1989) [15] that the soft denture materials having a 10 pounds per inch (4.5 kg/cm 2 ) bond strength are acceptable for clinical use.…”

“…Molloplast-B against an already polymerized PMMA showed a higher bond strength than Mollosil against PMMA (15.72 kg/cm 2 or 0.157 kgf/mm 2 ). This value was higher than that observed by Bates et al (1965) [4] (13.6 kg/cm 2 ) and lower than that observed by Khan et al (1989) [15] (23.9 kg/cm 2 ). The fi ndings of this study were more or less in line with the bond strength conclusions of the study drawn by Kawano (1992) [5].…”

“…Bond strength Molloplast-B packed against denture base trevalon in an un-polymerized form was even greater than the bond strength of Molloplast-B bonded with an already polymerized trevalon using primo adhesive. Adequate adhesive value of soft lining material for clinical usage is considered to be 10 pounds per inch (4.5 kg/cm 2 ) [14,15]. Since the adhesive bond strength observed in this study was minimum 10.0 kg/cm 2 (0.100 kgf/mm 2 ), both the soft lining materials used are acceptable for clinical usage.…”

The Effect of Primer on Bond Strength of Silicone Prosthetic Elastomer to Polymethylmethacrylate: An in vitro Study

“…The liners used were tru-soft, molloplast-b, and esscheem. They concluded that all of the materials tested bond sufficiently to triad to be considered clinically acceptable [9]. ER Dootz, et al, compared phy sical properties of 11 soft denture lining materials as a function of accelerated aging.…”
