Abstract: Dental curing light systems capable of monitoring the degree of curing of polymerizable dental material. A monitoring light source delivers visible monitoring light at one or more different visible wavelengths and a visible light detector detects the monitoring light diffusely reflected by the polymerizable dental material. The monitoring light has a wavelength of maximum emission (λmax-mon) that does not effectively induce polymerization of the polymerizable dental material. Change in intensity of the monitoring light reflected from the polymerizable dental material is used to determine when a selected degree of curing is reached in the polymerizable dental material.

Abstract: The present disclosure provides a polymer bond abrasive article formed of a continuous photocured polymer matrix having abrasive particles retained therein. The photocured polymer matrix includes at least one of an optical brightener or a light absorber, and the polymer bond abrasive article has a three-dimensional shape. An abrasive tool is also provided, including the abrasive article affixed to a shaft or a pad. Further, a method of making the polymer bond abrasive article is provided, including a) obtaining a photocurable composition liquid dispersion; b) selectively curing a portion of the photocurable composition; and repeating steps a) and b) to form the polymer bond abrasive article. The dispersion contains at least one photocurable component; abrasive particles; a photoinitiator; and at least one of an optical brightener or a light absorber.

Abstract: Disclosed herein are non-aqueous compositions including: a flowable Part A including at least one resin and Reactant A; and a flowable Part B including at least one resin and Reactant B; wherein at least one of flowable Part A and flowable Part B further includes a free radically polymerizable resin; wherein at least one of flowable Part A and flowable Part B further includes a free radical initiator system; wherein flowable Part A and flowable Part B are capable of being mixed to provide a flowable mixed composition; wherein when flowable Part A and flowable Part B are mixed, Reactant A and Reactant B are capable of interacting to cause a non-free radical reaction within a first staging time to provide a first staged stable consistency for the mixed composition; wherein Reactant A comprises an acid and Reactant B comprises a base, and upon mixing flowable Part A and flowable Part B, the Reactant A acid is capable of reacting with the Reactant B base in an ionic acid-base reaction; and wherein the mixed composition having the first staged stable consistency is capable of forming a hardened dental composition upon initiation of free radical polymerization.

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.

Abstract: The present disclosure provides a composite material, a method of making and using the composite material and dental products made by hardening the composite material. The composite material includes a polymerizable component, ceramic fibers and nanoclusters. Each of the ceramic fibers of the composite material has a length and where the length of fifty percent of the ceramic fibers, based on a total number of the ceramic fibers, is at least 50 micrometers and the length of ninety percent of the ceramic fibers, based on the total number of the ceramic fibers, is no greater than 500 micrometers. The composite material can also include discrete non-fumed metal oxide nanoparticles. The composite material can be hardened to become any one of a dental restorative, a dental adhesive, a dental mill blank, a dental cement, a dental prostheses, an orthodontic device, an orthodontic adhesive, a dental casting material or a dental coating.

The dental composition further comprises inorganic metal oxide filler having a discrete or aggregate average particle size of at least 200 nm. The nanoparticles are present at a concentration to provide a refractive index differential between the cured polymerizable resin and inorganic metal oxide filler such that the contrast ratio of the dental composition is at least 40.
