“…Techniques such as sandblasting, air abrasion, or laser treatment can be employed to create micro-roughness on the surface, improving adhesion and bonding strength. Plasma surface treatment involves exposing the polyamide denture base to a low-temperature plasma [14,15]. This treatment modifies the surface chemistry and topography, resulting in improved wettability and adhesion properties.…”

“…Stipho concluded that the highest transverse strength was found when the denture acrylic resin was enhanced by adding 1% glass fber before and after repair, and that the inclusion of higher than 5% glass fber content yielded no signifcant mechanical benefts [18]. Another study by Deb et al 2020 revealed that using glass fberreinforced autopolymerized acrylic resin as a repair material showed to have the highest fexural strength compared to unreinforced autopolymerized and light-cured acrylic resin [19]. Te E-glass fber has undergone extensive research, leading it to be widely recognized as one type of PMMA reinforcement.…”

The aim of this study was to analyze the effect of applying short E-glass fiber (SEG) and ultrahigh molecular weight polyethylene (UWPE) filler on the shear bond strength between the repaired surface of the rapid heat-cured and the reinforced autopolymerized acrylic resin. Fifty-six circular (15 × 3.3 mm2) rapid heat-cured resins were made and assigned equally to seven different groups. These were later bonded to fifty-six circular-reinforced autopolymerized acrylic resin specimens. Every test group included a control group, along with applying 1% and 2% SEG, 0.5% SEG/UWPE, 1% SEG/UWPE, and 1% and 2% UWPE. The universal testing machine was utilized to conduct the shear bond strength test. The repaired surface of these samples was assessed. Besides, the mode of failure was visualized under stereo microscope. The shear bond strength of all experimental groups was significantly higher than that of the control group. Group 3 with the addition of 1% SEG demonstrated the highest significance (12.86 MPa). The mode of failure for most of specimens was a mixed failure. Thus, it is indicated that enhancing the resin with 1% short E-glass fiber significantly improves the shear bond strength between repaired surface of the rapid heat-cured acrylic resin denture base and the reinforced autopolymerized acrylic resin.

Colonization of auto-polymerized acrylic resin by pathogenic Candida albicans is a common problem for denture users. In this study, zinc-modified phosphate-based glass was introduced into an auto-polymerized acrylic resin at concentrations of 3, 5, and 7 wt.%. The mechanical or physical properties (flexural strength, elastic modulus, microhardness, and contact angle), surface morphology of the resultant materials, and the antimicrobial effect on C. albicans were investigated. There were no statistical differences in the mechanical properties between the control and the zinc-modified phosphate-based glass samples (p > 0.05); however, the number of C. albicans colony-forming units was significantly lower in the control group (p < 0.05). Scanning electron microscopy revealed that C. albicans tended not to adhere to the zinc-modified-phosphate-based glass samples. Thus, the zinc-modified materials retained the advantageous mechanical properties of unaltered acrylic resins, while simultaneously exhibiting a strong antimicrobial effect in vitro.
