A dental composite material includes a hardenable resin matrix and a filler component. The filler component includes (a) a first plurality of preferably glass particles having an average particle size of from about 1 to about 10 micrometers; (b) a second plurality of preferably glass particles having an average particle size of from about 0.1 to about 1 micrometers; and, (c) a plurality of filler particles having an average particle size of from about 0.01 to about 0.04 micrometers. A method according to the invention includes compacting a dental composite material into a prepared tooth cavity, wherein the material has a packability index above about 300 g/mm .

Dental composite restorative material and method of restoring a tooth

This invention relates to a novel composition for use in dental flosses or tapes. More particularly, it relates to novel compositions containing a base polymer, a block copolymer and a nonmigrating compatibilizer or plasticizer that, in combination in a blend, result in a floss or dental tape having good breaking strength, elongation, tenacity, nick resistance and gentleness to the gums.

Process of making a tubular dental hygiene device

A method and material for forming translucent wear resistant dental enamel and the dental enamel material formed which has an opacity less than 50 percent and a localized wear volume loss of less than 0.025 mm,. The dental enamel material is formed from a polymerizable matrix and a filler. The material for forming translucent wear resistant dental enamel having an opacity less than 50 percent, a localized wear volume loss of less than 0.025 mm,and a localized extended wear volume loss of less than 0.04 mm,, comprises a polymerizable matrix forming liquid and inorganic filler particles. The liquid comprises polymerizable material having a first refractive index. The filler comprising a first plurality of particles having a second refractive index. The first plurality of particles being formed from a low and a high median particle size plurality of particles. The low median particle size plurality of particles having a median particle size between 0.1 and 1.0 micrometers. The high median particle size plurality of particles having a median particle size between 1 and 10 micrometers. The first refractive index being within 5 percent of said second refractive index. More preferably the low median particle size plurality of particles have a median particle size between 0.3 and 0.7 micrometers, and said high median particle size plurality of particles have a median particle size between 1 and 2 micrometers. More preferably the filler further comprises a second plurality of filler particles having an average particle size of from about 0.01 to about 0.04 micrometers.

Translucent wear resistant dental enamel material and method

A dental floss formed from a single hollow monofilament in the shape of a flattened tube. The monofilament is formed of a blend that includes a base polymer, a block copolymer and a compatibilizer.
