Abstract:
A dental article includes an external layer formed of a self-supporting hardenable preformed material having a dental article shape defined by an external layer surface. The external layer defines an interior volume. An interior material is disposed within the interior volume. The interior material is different than the external hardenable preformed material and the interior material has a yield stress value of 100 dyn/cm2 or greater.

Abstract:
Organic polymers for use in laminates including capacitors, wherein the polymer includes repeat units of the formula: wherein: each R 1 is independently H, an aryl group, Cl, Br, I, or an organic group that includes a crosslinkable group; each R 2 is independently H, an aryl group or R 4 ; each R 3 is independently H or methyl; each R 5 is independently an alkyl group, a halogen, or R 4 ; each R 4 is independently an organic group that includes at least one CN group and has a molecular weight of about 30 to about 200 per CN group; and n=0-3; with the proviso that at least one repeat unit in the polymer includes an R 4 .
Abstract:
Provided are methods of improving the wear resistance and aesthetic properties of dental articles though use of ceramics and microparticles, as well as dental articles having an abrasion resistant microparticle and ceramic coating thereon.
Abstract:
A method of using hardenable dental articles. The method can include placing a film (30) onto a dental structure (40) to cover at least a portion of the dental structure (40); providing a hardenable dental article (10); and applying the hardenable dental article (10) to the dental structure (40) covered by the film (30).
Abstract:
Curable dental compositions, dental articles, and methods of making or using such compositions or articles are described. In one embodiment, the curable dental restoration composition comprises a resin system comprising a free-radically polymerizable semi-crystalline resin having a molecular weight no greater than 2000 g/mole and at least 50 wt-% of nanocluster filler.
Abstract:
Provided are methods of improving the wear resistance and aesthetic properties of dental articles, as well as dental articles having an abrasion resistant ceramic/polymer hybrid coating thereon. The method for coating a dental article (20) comprises: providing a body comprising a mental substrate (30); priming at least a portion of a surface of the body; depositing a ceramic material on at least a portion of a surface of the body, wherein said depositing forms a ceramic layer (34) bonded directly to the surface: and depositing at least one hardenable composition comprising a polymerizable component on at least a portion of the ceramic layer, wherein depositing at least one hardenable composition forms a polymeric layer (36).
