  • the invention relates to a composition which is particularly suitable for restorative dentistry and in particular for improving surfaces of dental ceramic veneers.
  • Natural teeth are characterized by tooth enamel on the surface. This enamel is mechanically special. However, chemical attack can destroy the enamel. Enamel is predominantly composed of hydroxyapatite. This hydroxyapatite gives the tooth its typical appearance.
  • Stratification with different masses can lead to thermal stresses, which can be triggers for cracks or cracks, for example. These can occur immediately during manufacture or afterwards as so-called late jumps.
  • a composition which can reduce such stresses is described in EP 0847375.
  • Also admixture with the finished mass of hydroxyapatite as fine-grained particles is e-benso, as provided in US 4708652, provided (no ingredient in contrast to the composition of the invention).
  • the starting material contains no phosphate component (ie no calcium phosphate) and significantly less zirconium dioxide than the composition according to the invention.
  • Glaze masses are quick to apply, but are especially controversial in the case of allergic persons because of the release of interfering elements. In addition, many glaze masses are loosened or bitten away after a longer wearing time.
  • composition of the invention can be adjusted by modifiers aesthetically or mechanically or in other properties of the particular situation.
  • it has a calcium and phosphate content, which makes it similar to the natural enamel.
  • the object according to the invention is achieved by the glass ceramic, which by means of calcium phosphate comes much closer to the natural tooth in terms of its properties and at the same time can be used on several veneering ceramics due to the nature and composition.
  • the high solubility of hydroxyapatite which may be present in the composition of the invention, be lowered compared to the natural tooth.
  • the existing crystal phase can be out Hydroxylapatite or else consist of other calcium compounds. Danben may have leucite as another crystal phase.
  • the manufacturing process determines the nature and formation of the crystal phase.
  • Hydroxylapatite is widely used as a bioactive material, e.g. in the context of implants - EP 19816865.
  • hydroxlapatite it is crucial that hydroxlapatite can be present, but, as with natural tooth enamel, it is present as more or less bioinert material (gingiva is well accepted, but growth - eg of bone substance or damaging Bacterial colonies - not significantly promoted).
  • Blending dental materials are described in EP 1167311, EP 1170261 or EP 1329430, but these compositions all contain more than 50% SiO 2. Such compositions, especially with lithium disilicate, are often used as pressable masses for frameworks, e.g. US 6517623.
  • composition according to the invention contains no appreciable proportions of lithium disilicate.
  • the composition can also be overpressed by a veneer (not primarily a framework).
  • EP 1167311 requires a high ZnO content of 9-16%. This lowers the firing temperature.
  • the composition of the invention is to be fired at temperatures below 850 0 C, despite a significant ZrO 2 content, which increases the surface stability in order to ensure a broad application.
  • EP 1167311 are expected to provide smaller ZrO 2 contents.
  • Zirconium oxide has in the meantime proven itself particularly with dental framework materials and, due to its mechanical properties, in particular with stabilizers, has characterized the metal-free market (all-ceramic frameworks for long-span bridges).
  • the composition of the invention is characterized by:
  • ZrO 2 5-10 (with or without stabilizers, such as Y 2 O 3, CeO 2, or MgO)
  • Excipients e.g., pigments, property modifiers
  • this compound is compatible with many dental ceramic materials and can therefore be applied to many artificially produced ceramic teeth.
  • Lithium disilicate scaffolds as described in EP 1167311 are not a mandatory basis.
  • the composition should not have any appreciable proportions of lithium disilicate and should normally not be applied directly to substrates but as a last layer on veneers, in order to make them match the natural tooth enamel without, however, having the same life-time-degrading chemical solubility. However, if the last layer is to be applied directly to the dental framework for clinical or dental considerations, this is also possible.
  • the mass Due to the special design of the mass, it can be fired on a wide variety of masses. This includes in particular certain metal ceramic compositions and all-ceramic compositions with different thermal expansion coefficients and firing temperatures.
