Abstract
A dental material having (a) at least one radically polymerizable monomer, (b) at least one radiopaque filler, (c) at least one inorganic filler, (d) at least one composite filler, and (e) at least one initiator for the radical polymerization, wherein the monomer (a) comprises at least one urethane (meth)acrylate, at least one radically polymerizable bisphenol A derivative, optionally at least one polycyclic aliphatic dimethacrylate, optionally at least one monomer which does not fall into one of the groups (a-1) to (a-3) and (a-5), and optionally at least one chain regulator (a-5). The dental material allows the fabrication of esthetically pleasing restorations with only one material.
Claims16
A dental material that comprises
- (a) 5 to 40% by weight of at least one radically polymerizable monomer,
- (b) at least one radiopaque filler comprising 1 to 30% by weight ytterbium trifluoride particles having an average particle size of <25 nm, wherein the average particle size is the number-averaged D50 value,
- (c) 20 to 90% by weight of at least one inorganic filler,
- (d) 5 to 60% by weight of at least one composite filler and
- (e) 0.005 to 3.0% by weight of at least one initiator for the radical polymerization,
- in each case in relation to the total mass of the dental material
- wherein the dental material comprises as monomer (a)
- (a-1) at least one urethane (meth)acrylate,
- (a-2) at least one radically polymerizable bisphenol A derivative,
- (a-3) optionally at least one polycyclic aliphatic dimethacrylate,
- (a-4) optionally at least one monomer which does not fall into one of the groups (a-1) to (a-3) and (a-5), and
- (a-5) optionally at least one chain regulator.
