Purpose: In the dental field, acrylic resin can be used to produce various orthodontic appliances. The manufacturing of orthodontic resin requires the insertion of dental wires. However, currently, no study has compared the mechanical properties when dental wires are inserted into the orthodontic resin. Methods: In this study, specimens measuring 3.3 mm×10 mm×65 mm were produced by inserting 0.7- and 0.9-mm wires. A dental wire was used to create a specimen with the following configurations: single wire, two wires bonded together, and two wires spaced 5 mm apart. The flexural strength, flexural modulus, proportional limit, and work of fracture of the fabricated specimens were measured using a universal testing machine. Results: The dental resin inserted with wires demonstrated increased mechanical properties including bending strength, elastic modulus, yield strength, and fracture energy. The bending strength of the fabricated orthodontic resin specimens increased as the diameter of the wire expanded. Conclusion: Thus, the insertion of dental wires into dental resin increased the strength of the manufactured orthodontic appliance.
