Evaluation of Fracture Resistance for Autopolymerizing Acrylic Resin Materials Reinforced with Glass Fiber Mesh, Metal Mesh and Metal Wire Materials: An <i>in Vitro</i> Study

Abstract

Statement of problem: Many processes have been applied to improve the fracture resistance of acrylic resin dentures by reinforcing them. The maximum goal of any denture repair is to restore the main strength of the denture and to avoid further fracture. Purpose: This study investigated the ability of self-curing acrylic resin to be strength and deflection of repaired acrylic resin joints reinforced with various reinforcement materials to resist fracture. Material and methods: Transverse strength of polymethyl methacrylate acrylic resin reinforced with glass fiber mesh, metal mesh, and metal wire was evaluated with a 3-point load test on 40 intact specimens (n = 10 for control group) (n = 10 per each reinforcement material group). Fractured joint margins were rounded, a 4-mm gap was placed between them, and then they were repaired with autopolymerizing acrylic resin and retested. Results: Transverse strength for the polymethyl methacrylate acrylic resin samples has showed fracture at the side of sample rather than in the middle area of reinforcement materials and some other samples showed bending statue rather than fracture. Conclusion: Reinforcement with glass fiber mesh, metal mesh, and metal wire produced transverse strength in the side area of resin denture base material rather than in the middle of reinforcement area with bending samples rather than fracture response.

Evaluation of flexural strength, impact strength, and surface microhardness of self-cured acrylic resin reinforced with silver-doped carbon nanotubes

“…Researchers have made numerous attempts to improve the mechanical performance of the self-cured PMMA resin [ 22 , 54 , 56 , 57 ]. The improvement of the mechanical properties of acrylic resin could be achieved through reinforcement with several fibers and nanoparticles [ 52 , 54 ].…”

Ergonomic Sports Mouthguards: A Narrative Literature Review and Future Perspectives

“…Nylon fibers possess polar amides that enable adjacent chains to form hydrogen bonds, which enhances their crystallinity, strength, and durability. The effectiveness of reinforcements using these fibers depends on their structural design and orientation, as well as the applied force and their interaction with the material to be reinforced for load transfer [39]. Moreover, one of the most successful methods to enhance the mechanical properties of acrylic resin is the incorporation of silica nanoparticles, which have significant effects on both mechanical and thermal aspects.…”

“…Moreover, one of the most successful methods to enhance the mechanical properties of acrylic resin is the incorporation of silica nanoparticles, which have significant effects on both mechanical and thermal aspects. Based on this, studies have been conducted where this structure was incorporated into polymers like acrylic resin and bisacrylic to fabricate temporary fixed prosthetic structures [39] and mucosa-supported and implant-supported complete arch dentures [39][40][41], resulting in improvements in the strength of the tested structures. With these positive results, a proposal was made by our research group to increase the absorption of impacts using this fiber as a reinforcement in customized mouthguards; this proposal is under development and an example is shown in Figure 4 below.…”
