[Analysis of the mechanical properties of a material of temporary structures manufactured by direct method and provisional crowns made by 3D printing].

Unlabelled: The aim of this work is to study the mechanical properties of temporary composite crowns and temporary composite orthopedic structures manufactured by 3D printing.

Materials And Methods: For the two studied groups of samples: the original 3D-printed samples and the poured samples from a composite material of a certain shape, 8 samples were made and visually checked for the absence of porosity. The strength and elasticity were measured using the three-point bending method and the hardness was measured using the indentation method.
