Abstract
A dental composite or coating that comprises at least one photopolymerizable resin, at least one inorganic filler, a photoinitator, and at lease one interference platelet. The dental composite is able to adapt and match the color and shade of adjacent tooth structure in the cavity in which it is placed, without the need for conventional dyes and pigments, although it may be desirable to use dyes and pigments in a specific shade series.
Claims20
A curable dental composition comprising a photocurable resin, at least one filler, a photoinitiator and at least one interference platelet to form a translucent composite in a colored cavity surrounding said composite, wherein said translucent composite mimics the color of said surrounding cavity, wherein the at least one filler and the photocurable resin both have refractive indices and the difference between the refractive index of the filler and the refractive index of the photocurable resin after curing is not greater than 0.03.
A curable dental composition comprising a photocurable resin, at least one filler, a photoinitiator and at least one interference platelet to form a translucent composite in a colored cavity surrounding said composite, wherein said translucent composite mimics the color of said surrounding cavity, wherein the at least one interference platelet comprises between 100 and 1500 part per million of said curable dental composition, wherein the said filler comprises at least 50% silica, and wherein at least a portion of the silica has a primary particles size greater than 30 nm.
