A dental crown composed of fiber mesh sheets of fiberglass, aramid, carbon or quartz fibers embedded within dentally acceptable resin. The combination of both materials synergistically add unsurpassed strength and enhanced cosmetic value to the dental crown for a much lower price due to the cheaper costs of the material and manufacturing process.

Provided herein are high performance dental restoration compositions, particularly two-part compositions having good self-cure times. Also provided herein are methods for restoring or filling a cavity in a tooth in an individual with the two-part dental restoration compositions. In particular, compositions provided herein are useful in restoring large cavities, including Class I and Class II cavities.

A dental self-adhesive resin cement is provided comprising a two-component system. A first catalyst component includes one or more acidic monomers. A second base component includes one or more basic fillers. The mixture of the first and second components is polymerizable and has an initial pH that is acidic immediately after mixing and a pH of at least about pH 8 after polymerization.

A composition comprising microcapsules functionalized with polymerizable functional groups on the surface of said microcapsules wherein the functional groups form covalent bonds with monomers in the continuous phase to enhance the mechanical properties of the composition.

An aqueous dental glass ionomer composition comprising (A) a reactive particulate glass, (B) a water-soluble polymer comprising acidic groups, which is reactive with the particulate glass in a cement reaction, (C) a water-soluble, hydrolysis-stable monomer having a single polymerizable double bond and optionally a carboxylic acid group or hydroxyl group; (D) a water-soluble, hydrolysis-stable polymerizable crosslinker having at least two polymerizable carbon-carbon double bonds; and (E) a polymerization initiator system.

The present invention provides a dental polymerizable composition that requires less discharging force, is easily formable, has low polymerization shrinkage stress during curing, and exhibits high stain resistance and surface gloss when cured. The present invention relates to a dental polymerizable composition including a (meth)acrylic block copolymer (A), a polymerizable monomer (B), and a polymerization initiator (C). The (meth)acrylic block copolymer (A) consists of a (meth)acrylic polymer block (a) having a curable functional group and a (meth)acrylic polymer block (b) having no curable functional group. The curable functional group has a partial structure represented by the following general formula (1):
