“…In contrast, a study by Yu et al [38] showed increased FS and FT at 5.3 wt.% and 7.9 wt.% loadings of GL/UHMWPE fibers. Additionally, a study by Mathew et al [52] demonstrated statistically higher FS at 10 wt.% loadings of hydrogen plasma-treated polypropylene fibers. The other studies either claimed no effect on FS [29] or reported enhanced FM, SH, or CS at elevated filler loading levels [43,44,50].…”

“…All of these studies used nano-sized particles, except for Al-Bakri et al [35], in which 1.5 µm sized glass fillers were used. Glass fibers and other types of polymeric fibers were of also interest to investigators [31,32,34,[37][38][39][40][41]51,52]. There was less of an inclination towards the use of minerals such as mica, borax, boric acid, and colemanite as reinforcing agents in denture base resin [43,53].…”

Influence of Reinforcing Agents on the Mechanical Properties of Denture Base Resin: A Systematic Review

et al. 2021

Knowledge about the influence of fillers in denture base resin is vague. This systematic review aimed to report the reinforcing effect of fillers on the mechanical properties of denture base resin by following PRISMA guidelines. Two electronic databases (Pubmed/Medline & Web of Science) were searched for articles using the keywords: fibers in denture base, fillers in denture base, and reinforcement of denture base. Laboratory studies complying with the inclusion criteria were reviewed according to the set protocol. The established focus question was: “Do reinforcing fillers positively influence the mechanical properties of polymethyl methacrylate (PMMA) heat polymerized denture base material?” A total of twenty-nine relevant papers qualified for final inclusion. Of these, 24 were determined to have a moderate risk of bias. Micron or nano-sized metal/metal oxides particles and glass fibers were the frequently used reinforcing agents. The trend of evaluating fractural strength (FS) was common. Most of the studies limited the use of reinforcing agents up to 5 wt.%. FS, fracture toughness (FT), and impact strength (IS) tend to increase if the fillers are chemically bonded and well-dispersed in denture base resin. Though fillers with a higher elastic modulus increase the hardness of the reinforced denture base resin, they compromise other mechanical properties. Well-dispersed lower filler loading PMMA denture base resin can enhance the FS, FT, and other related mechanical properties.

“…Mathew et al 14 suggested that among the PPF reinforced test group (3, 6, and 12 mm length of the fiber and 2.5, 5, and 10 wt%), a 6 mm long fiber reinforced in 2.5 wt% resulted in the best flexural strength value. In addition, Mathew et al 13 suggested that fiber weight percentage, fiber length, and adhesion between fiber and matrix play an important role in flexural characteristics of the hydrogen plasma‑treated PPF‑reinforced PMMA polymer. In the present study, 5 wt% added PPF supports the study conducted by Mathew et al that the addition of PPF 5 and 10 wt% is required to get better mechanical properties coupled with an easy and cost‑effective reinforcing procedure.…”

“…PPF is widely used in surgery because of low density, high strength, and high biocompatible. 13 In addition, they enable the natural looking and biocompatible strengthening properties of PMMA. 4 In the literature, limited studies focused on strengthening of PMMA with PPF.…”

“…4 In the literature, limited studies focused on strengthening of PMMA with PPF. 13,14 The influence of PPF addition into the PMMA on the physical properties of denture base resin is still exactly unknown. Therefore, the purpose of this study was to evaluate the effect of addition of different ratios of PPF into denture base materials on impact strength, water sorption, and cytotoxicity of denture base resin.…”

Aim: Polymethyl methacrylate is the common material used as a denture base. Ease of application, stability in the oral environment are its advantages; however, its mechanical properties should be enhanced. This study aimed to evaluate the effect of different ratios of polypropylene fiber (PPF) in addition to denture base materials on impact strength, water sorption, and cytotoxicity. Materials and Methods: Heat-cure acrylic resin specimens were prepared according to the manufacturer’s instruction by adding PPFs of 6 mm length in different ratios (1, 3, 5, 10, and 20 wt%). In order to determine the impact strength, specimens were subjected to a Charpy impact test machine after being kept in distilled water at 37°C for 48 h. A span of 40 mm was adjusted and a 0.5 J pendulum was used. The fractured surface of specimens was also analyzed using a scanning electron microscope. In addition, mouse fibroblast cells and agar diffusion tests were used for cytotoxicity determination. The results were analyzed using the Kruskal–Wallis and the Mann–Whitney U tests for determining impact strength, and Kruskal–Wallis and Tukey’s range tests were performed for determining water sorption values ( P = 0.05). Results: 5 wt% PPF group exhibited the highest water sorption and impact strength values, and the difference was statistically significant ( P < .05). On the other hand, no cytotoxic effects were determined in PPF added groups. Furthermore, increased fiber concentration caused less water sorption. Conclusion: Addition of PPFs in acrylic resin increased the impact strength and decreased water sorption without any cytotoxic effects.

A review of the fabrication methods and mechanical behavior of continuous thermoplastic polymer fiber–thermoplastic polymer matrix composites

et al. 2022

View full text Add to dashboard Cite

Thermoplastic polymer fiber-thermoplastic polymer matrix composites (PPCs or PRFPs), often recognized as self-reinforced or single polymer composites, are potential candidates for future advanced polymer composites because of various advantages (e.g., recyclability, formability, low-cost, ultra-lightweight, environmental friendliness, etc.). The manufacturability and mechanical behavior of these composites compared to conventional carbon-/glass-/aramid-fiberreinforced polymers is of great interest to the composites community, but there are a limited number of studies in this area. To this end, this paper reviewed fabrication methods with different processing parameters and mechanical behavior of uni-/multi-directional thermoplastic PPCs featuring continuous thermoplastic Lisa D. Fring and Madhusudhan R. Pallak contributed equally to this study.
