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.
