Abstract: We investigated patterning with curable dental materials via micro/nano-molding as a screening trial. We used typical curable dental materials such as a composite resin (CR), acrylic resin, varnish, adhesive resin, restoration, sealer, cement, tooth desensitizer, and gypsum with either a cyclo-olefin polymer (COP) mold or polydimethylsiloxane (PDMS) mold that had holes, pillars, and grooves with 0.5 μm diameters and 1 μm heights. The COP mold was suitable for patterning of holes and grooves with Bondfill SB after 2 h curing, while PDMS mold was suitable for patterning of pillars with Bondfill SB at the 0.5 μm scale after 2 h curing. Most of the curable dental materials could be patterned using the COP or the PDMS mold. However, dental impression materials could not be patterned as required. In addition, the COP mold was suitable for many organic pillars, while the PDMS mold was suitable for inorganic pillars. Further, we achieved patterning on the curved surface of an artificial tooth with flowable CR using the COP thin film mold. We conclude that for the formation of uniform shaped patterns, it is important to cure within a suitable time and to select mold types depending on the type of curable dental material.
