Dental compositions comprising a fatty mono(meth)acrylate

摘要

Presently described are dental compositions comprising one or more fatty mono(meth)acrylates, methods of use, dental articles, and methods of making dental compositions. It has been found that a relatively low concentration of a fatty mono(meth)acrylate can improve the handling characteristics of a dental composition by reducing the tendency of the composition to stick to a dental instrument and/or by reducing the tendency of a dental composition to string when being manipulated by a dental instrument. In one embodiment, a hardenable dental composition is described comprising a polymerizable resin composition comprising at least one multifunctional ethylenically unsaturated monomer; 0.2 to 10 wt-% of one or more fatty mono(meth)acrylate monomers; and at least 50 wt-% of inorganic oxide filler.

主权项

1. A method of making a dental composition comprising:
providing a hardenable dental composition comprising a polymerizable resin composition and at least 50 wt-% of inorganic oxide filler, wherein the dental composition exhibits tackiness or stringiness when manipulated with a dental instrument; and adding fatty mono(meth)acrylate monomers in an amount ranging from 0.2 to 10 wt-% of the hardenable dental composition, wherein the fatty mono(meth)acrylate monomer phase separates from the polymerizable resin composition such that the fatty mono(meth)acrylate forms microscopic domains such that the tackiness or stringiness is substantially reduced.
