Impact of curing temperature on accuracy and physical properties of additively manufactured FDPs and bar specimens.

ABSTRACT: Additive manufacturing based on photopolymer resins requires additional light curing during postprocessing to achieve the final mechanical properties. The present in-vitro study aimed to evaluate the impact of the curing temperature during postprocessing on the fracture resistance and accuracy of both additively manufactured four-unit fixed dental prostheses (FDPs) and bar-shaped, ISO-conform specimens. All samples were fabricated by either additive manufacturing using two different light-curing resins or subtractive manufacturing using polymethyl methacrylate. Three different curing temperatures were evaluated (40 °C, 60 °C, 80 °C). All bars (n = 136) were subjected to a three-point bending test after 68 of them had been stored in water for 24 h. All bridges (n = 90) were analyzed for dim
