Mechanical properties of 3D‐printed and milled composite resins for definitive restorations: An in vitro comparison of initial strength and fatigue behavior

Abstract

The clinical indications of the investigated novel 3D-printed composite resin should be limited to long-term provisional restorations. A cautious procedure for mixing the components is crucial before the 3D-printing process, since nonhomogeneous areas developed during the mixing could act as fracture origins.
