accompanied by technological updates. Zhao et al. [159] used forces. The bending and compression resistance of the
DIW to produce high-precision crowns using multiscale crowned structure was superior to the corresponding values
and highly ordered HA frameworks. The smooth printing of of conventional specimens made by molding (Figure 5A).
“supergravity+” HA nanorod-enhanced hybrid resin-based Mai et al. [160] used PolyJet 3D printing to fabricate
composites was made possible by designing a nozzle with temporary crowns with photosensitive resin and showed
channels that gradually shrank in response to shear-induced that the crowns had better fit and higher marginal accuracy
