Purpose: The aim of the research was to achieve recipes of 3D - printing resins for provisional restorations that provide wide choice of shade colors. Methods: Three types of resins: White Resin?, Model Resin? and Dental LT Clear Resin? (FormlabsTM) were combined and mixed in different proportions. After the polymerization process the shade of each samplethe values: Color difference (??), Chroma, Value and Hue was measured using a color measuring device VITA Easyshade?. Results: The shades B1, B4 and C4 can be easily reproduced by the newly created resins for temporary restorations. The results about shades A4, B2, B3 and D4 deviate from the acceptable norm for color difference (???5.0). Conclusion: The created resins have limitations in reproducing of a greater variety of shades and the choice is limited up to seven primary colors. Only three of them find place within the tolerance of color deviation and are unnoticed to the untrained eye of the patient.
