Definitions
- the invention relates to veneering ceramics for dental restorations, wherein the framework ceramic consists of yttrium-stabilized zirconium dioxide.
- the properties of the veneering ceramics are determined by the chemical composition, the crystal phases, the crystalline structure and the grain size of the starting material. The goal is to meet the high mechanical, chemical and aesthetic requirements of the veneering ceramics while at the same time reducing the manufacturing costs involved in the modeling of the veneering ceramics.
- the prior art is characterized by leucite-containing dental ceramics.
- the leucite content is in the range of 35 to 60% by weight.
- the flexural strength of the veneering ceramic with leucite crystals is about 80 MPa.
- the dental materials preferably contain apatite crystals.

- the veneering ceramic is provided with a formed during the crystallization thin glass layer.
- Lithium disilicate forms the main crystal phase of the veneering ceramic. It is desired, but not essential, that in addition to the lithium disilicate partially niobium oxide is crystallized out. Niobium oxide is not or only in small quantities incorporated into the structure of lithium disilicate. By means of controlled crystallization niobreiche phases are enriched in the immediate vicinity of the lithium disilicate.
- niobium oxide-rich glass phases allow a very high surface quality of the veneering ceramic, so that no separate glaze firing is required.
- the concentration of the individual color components should be at a maximum of 3.0 Ma. % lie.

- the fritted starting glasses are tempered for about four hours at 540 ⁇ 50 ° C and pulverized after cooling.
- the particle size used is between 0.3 ⁇ m and 30 ⁇ m.
- Crystallization of the veneering ceramic begins at a temperature of 760 ° C. In the temperature range from 760 ° C to 840 ° C occur in addition to lithium disilicate and the crystal phases lithium metasilicate and Christobalite. As the temperature increases, the crystal phases lithium metasilicate and Christobalite dissolve.

- the crystallization temperature of 900 ° C the X-ray diffractogram (XRD) is shown in FIG.
- FIG. 3 shows the microstructure of the veneering ceramic by means of scanning electron microscopy.
- the application of the veneering ceramic can be done either as a paste by brush or by spraying.
- spraying is preferred, it being possible to spray both monolayer and multilayer.
- Another method is given by the fact that the veneering ceramic is melted at a temperature of about 1000 ° C on the framework ceramic of yttrium-stabilized zirconia as a transparent glass.
- the melting of the glass can take place both via a ceramic furnace and through the use of a laser.
- the veneering ceramic applied to the yttrium-stabilized zirconium dioxide above the liquidus temperature serves as starting material for laser-induced crystallization in the veneering ceramic. Due to the defined use of the laser, it is possible to make the applied layers partly glassy or to subject them in certain areas of a targeted crystallization. A possible sequence for the crystallization by means of laser takes place according to FIG. 4.
