A dental material using nano material that will serve as reinforcement and will enhance mechanical properties with minimal sacrifice in other properties including processability of a dental material. The dental material may be used as a filling, restorative, cement, liner, adhesive or primer. This is achieved by combining several polymerizable monomers and/or oligomers, a polymerization initiator, at least one hyperbranched additive and at least one of an electrospun nanofiber, an electrospun nanosphere or a hyperbranched macromolecule. The hyperbranched additive may be hyperbranched molecules, dendridic molecules (such as dendrimers). In a preferred embodiment a caged silica (such as POSS) is used for a caged macromolecule. The material may also include nanoclay or traditional composite fillers. The material may optionally include accelerators (such as DEHPT), cross linkers or pigment |
