Definitions
- the invention relates to a polymerizable, dental composite material comprising (i) 40 to 90% by weight of at least one inorganic filler component comprising at least one dental glass with an average particle size d 50 of 0.5 to 10 ⁇ m, in particular 0.7 to 7.5 ⁇ m and optionally at least one amorphous metal oxide, (ii) 10 to 60% by weight of at least one urethane (alkyl) acrylate of the formula I, in particular a mixture of at least two different urethane (alkyl) acrylates, in particular urethane (meth) acrylates, (iii) 0.01 to 15% by weight of at least one di-, tri-, tetra- or multi-functional monomer that is not a urethane (alkyl) acrylate, in particular not a urethane (meth) acrylate, and (iv) 0 , 01 to 10% by weight of at least one initiator, an initiator system and optionally stabilizers and optionally pigments, the
- dental composites which can be used universally for a direct adhesive restoration as well as for the extraoral production of indirect dentures.
- inorganic-organic hybrid materials with larger proportions of inorganic fillers, such as dental glass and / or mineral nano-agglomerates, are basically suitable for this.
- the microfiller composites with prepolymer fillers introduced in the 1980s are not suitable for use in the posterior region (classes I and II) due to their limited material load capacity (flexural strength).
- the object of the invention was to provide a dental composite material which is suitable for the production of dental filling materials as well as for the production of larger blocks of material, in particular of geometric shaped bodies such as milling blocks.
- the composite material should have very good values for the fracture toughness, which represents a measure of the force required to propagate cracks in a material.
- a further object was to provide a dental composite material which has a homogeneous, monochrome coloration before and after the polymerization. It should not only be possible in the production of dental filling materials but also a homogeneous, monochrome coloration for larger blocks of material. Furthermore, it should be possible to produce polychrome, i.e. multi-colored blocks of material with a defined coloring.
- a dental composite material should be provided that shows sufficient flow properties in the unpolymerized state and can nevertheless be converted into a polymerized state with excellent mechanical properties by means of UV radiation or visible light.
- a dental composite material is also to be provided that, in the polymerized state, exhibits little shrinkage, even when larger blocks of material are produced.
- the composite material should not develop cracks or pores during curing, even in the case of large-volume material blocks.
- the subject of the invention is a composite material according to claim 1, a polymerized composite material according to claims 11 and 12 and the use according to claim 14, preferred embodiments are explained in the dependent claims and in detail in the description.
- the particle size distribution can, depending on the desired filler content, be rather broad for a high packing density and excellent mechanical properties, or it can also be designed rather narrow for specific applications.
- the mean value of the particle size distribution can be in the range from 0.5 ⁇ m to 10 ⁇ m, preferably in a range from 0.7 ⁇ m to 7.5 ⁇ m.
- the particle size distribution can be based on a content of 5 to 75% by weight of a dental glass with a particle size distribution of d50 of a dental glass fraction in the range from 0.7 to 2.0 ⁇ m, in particular 1.2 to 2.0 ⁇ m (micrometers) be adjusted to the overall composition, preferably with d 50 of 1.8 ⁇ m with plus / minus 0.25 ⁇ m, particularly preferably d 99 less than or equal to 20 ⁇ m or d 99 less than or equal to 10 ⁇ m.
- further dental glass fractions with deviating smaller and / or larger particle size distributions can be added in order to optimally match the packing density.
- the coordinated packing density enables optimal setting of the mechanical properties and reduced shrinkage.

- Legend w distance between the center of the two holes and the opposite edge of the specimen
- B width of the entire test specimen
- I 2 distance between the center of the two holes, which are arranged symmetrically to the plane of the crack +/- 0.005w;
- the pins and holes should have a smooth surface and a loose fit to avoid friction.
- K Ic [P / h ⁇ W 0 ' 5 ] f (a i / W)
- the specimens are then attached in a universal test machine (Zwick / Roell) with metallic pins that are passed through the holes.
- the test specimen is then subjected to a defined tensile force (P) via the pins until it breaks at a speed of 1 mm / min.
- the tensile force (P), the thickness (B) and the width (W) as well as the crack length a i , the fracture toughness K Ic are calculated using the following formula.
