Prosthesis, 2(3), 240–245. https://doi.org/10.3390/prosthesis20300212673-1592http://hdl.handle.net/11268/11233This article aimed to assess the marginal fit of methacrylate-oligomer-phosphine-oxide curable-resin provisional-fixed dental prostheses made by digital-light-processing (DLP) three-dimensional (3D) printing. A stainless-steel master model with two abutments was scanned, and five three-unit provisional bridges were designed and printed in VITA shade A3.5 curable resin in 50 μm-thick layers. The marginal fit of each abutment was measured at six points using a profile projector. A descriptive data analysis of the fit measurements was performed by descriptive and explorative processes with the SPSS software. The curable-resin provisional restorations made by DLP 3D printing reached values of 46.37 μm (SD: 29.58 μm), which were considered clinically acceptable, with values similar to polyethylene-methacrylate and polyether-ether-ketone provisional restorations.engAttribution 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/Prótesis dentaljournal article10.3390/prosthesis2030021open accessOdontologíaTecnología médica
