Abstract: A radiation curable composition including at least one radiation hardenable component, a photo-initiator, and a filler material having a population of particulates in an amount greater than or equal to 50% by weight of the printable composition. The population of particulates exhibits a median diameter (D50) of greater than or equal to 0.3 micrometer on a volume-average basis as determined using the Particle Size Test Method, and the radiation curable composition exhibits a viscosity of less than or equal to 150 Pa s when measured using the Viscosity Test Method. A method, apparatus, and systems for producing composite articles by selectively exposing a portion of the radiation curable composition to a source of actinic radiation to at least partially cure the exposed portion of the radiation curable composition, thereby forming a hardened layer, preferably by an additive manufacturing process such as stereophotolithography, are also described. The composite articles may include composite dental restorations.

Each of the ceramic fibers has a diameter and a length, the ceramic fibers having an arithmetic mean diameter of 0.3 micrometers to 5 micrometers, and the length of fifty percent of the ceramic fibers (based on a total number of the ceramic fibers) is at least 10 micrometers and the length of ninety percent of the ceramic fibers is no greater than 500 micrometers. The present disclosure also provides a method of making the composite material. The method includes obtaining components and admixing the components to form a composite material. Further, the present disclosure provides a method of using a composite material including placing a composite material near or on a tooth surface, changing the shape of the composite material near or on a tooth surface, and hardening the composite material. In addition, the present disclosure provides dental products and kits. Hardened composite materials can exhibit high strength.
