Influence of cleaning solutions and hydrothermal aging on the flexural strength and microhardness of resins for additively manufactured definitive fixed restorations
Resin type, cleaning solution, and aging condition affected the flexural strength and microhardness of AM resins intended for definitive restorations. Regardless of hydrothermal aging, AM-CR had the lowest flexural strength when the methyl ether solvent was used, while cleaning solution type did not affect the strength of AM-UA; AM-CR's strength was lower than AM-UA's with methyl ether. Regardless of hydrothermal aging, AM-CR and AM-UA had higher microhardness with ethanol and IPA than with methyl ether solvent. AM-CR had higher microhardness than AM-UA, regardless of cleaning solution. After hydrothermal aging, the microhardness of AM-CR decreased with the water-based solvent.
