3D-printed strong hybrid materials with low shrinkage for dental restoration

Composites Science and Technology 2021 Volume 213, Article 108902

Flowable photocurable resins can be printed effectively by stereolithographic 3D printing for dental applications; however, the 3D-printed objects’ mechanical properties cannot meet the requirements for the dental restorative materials. In this study, a strong customized crown for tooth repair was first prepared via direct ink writing 3D printing from a high-viscosity hybrid paste of acrylic monomer and multi-scale inorganic particles. The results showed that the hybrid resin-based composites (RBCs) could be printed successfully and smoothly through a metal nozzle with a gradually shrinking channel. The theoretical simulation of finite element methods was consistent with the experiment results. The printed objects…
