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.

Abstract: Disclosed herein are aqueous dental coating compositions and methods for enhancing contrast of intraoral surfaces for 3-dimensional digital scanning. The compositions include: an aqueous solvent system; a water soluble polymer present at no greater than 5 wt. %, based on the total weight of the aqueous dental coating composition; hydrophilic particles; and hydrophobic particles, wherein the aqueous dental coating composition is a dispersion or a dispersion of the hydrophilic particles and hydrophobic particles in the aqueous solvent system can be formed by shaking the composition for 30 seconds.

Abstract: Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.
