Effect of Carbonated Beverages on the Flexural Strength of 3D Printing Resins

Objective: This study aims to provide meaningful information so that temporary restoration becomes a high-quality prosthesis when functioning in the oral cavity by comparing and evaluating the difference in flexural strength between carbonated and electrolyte drinks after printing resin, which is used as temporary teeth among photopolymerizable 3D printing resins, as instructed by the manufacturer.Methods: According to the manufacturerʼs manual for photopolymerizable 3D printing temporary dental resin, 70 specimens were produced, 10 specimens per group.After that, the flexural strength according to the elapsed time was measured and compared after immersion in water, carbonated drinks, and electrolyte drinks as control groups for 0, 24, and 48 h.Results: Compared to the flexural strength of the specimen measured after photopolymerization, the flexural strength measured after 24 hours and 48 hours of deposition decreased.There was no significant difference in flexural strength according to the deposition time of Power-Aid, an electrolyte drinks.However, Coca-Cola, a carbonated drinks, showed a significant difference in flexural strength according to deposition time.Conclusion: Among 3D printing resins, the resin used for temporary dentures shows a slight change in flexural strength when immersed in water, etc.However, there was no difference in the flexural strength between water and electrolyte drinks, but there was a difference in the flexural strength of carbonated drinks.Since frequent consumption of carbonated drinks while wearing temporary teeth in the mouth can affect the flexural strength, we intend to use this as basic data for oral care education.
