<P>PROBLEM TO BE SOLVED: To provide a dental restorative composite having self-healing capabilities to repair discontinuities in the composite. <P>SOLUTION: The dental restorative composite includes a microsphere that encapsulates a monomer. When a fracture occurs, the microsphere is ruptured and the monomer fills the fracture. Depending on the monomer present in the microsphere, the monomer is polymerized by a polymerization initiator or by an olefin metathesis catalyst present in the dental restorative composite. The self-healing dental restorative composite provides high resistance to fracture, and thus remains substantially intact for a relatively long period of time, and preserving the remedial integrity of the dental repair or reconstruction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
