Abstract: Dental crowns and methods of making the same. The dental crown may include a metal shell shaped to cover a portion of a tooth of a patient; a coating retention metal layer diffusion bonded to the metal shell, wherein an interface between the coating retention layer and the metal shell comprises a plurality of interstitial regions; and a composition on the coating retention layer and within the plurality of the interstitial regions to bond the coating composition to the metal shell.

Abstract: Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.

Abstract: A method of applying a two-part dental sealant is described comprising providing a syringe device (1) comprising a cartridge (10) including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle (17) comprising a static mixer and an outlet at one end of the cartridge and a plunger (20) at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.
