A dental composition comprising a polymerizable acidic compound of the following formula (I): 

Dental composition

A method of forming a dental composite includes photopolymerizing a dental composition. The dental composition includes a free-radically polymerizable (meth)acrylate resin, 75 percent by weight or greater of filler particles, and about 0.005 percent to about 5 percent by weight of at least one polymerizable stable radical. The photopolymerizing forms the dental composite such that the dental composite has a flexural modulus of about 9500 MPa or greater and the polymerizable stable radical reduces shrinkage stress of the dental composite caused by the photopolymerizing by 10% or greater. A method of forming a dental composite composition includes combining a free-radically polymerizable (meth)acrylate resin, 75 percent by weight or greater of filler particles, and about 0.005 percent to about 5 percent by weight of at least one polymerizable stable radical to form the dental composite composition.

Methods of forming dental composites and compositions for reduced shrinkage stress

Described is a stable, two-component low viscosity composite that is capable to achieve excellent adaptation to walls/substrates due to its intrinsic flow ability and is also capable of rapid viscosity increasing and being manipulated prior to cure by light upon mixing of such a two-paste composite due to one distinguished reaction promoting partial network formation thus to allow a practitioner further manipulate a firm composite. Upon a completed manipulation by the practitioner, such a mixed material should be readily cured into final solid form by using conventional curing light.
