Definitions

• the invention relates to an adhesion promoter between a synthetic or mixed from natural minerals oxide ceramic, consisting of one or more metal oxides such as zirconia, alumina or spinel ceramic, and a applied thereto veneering material, such as silicate, Verblendkomposite or veneering, especially for dental purposes.
• natural minerals oxide ceramic consisting of one or more metal oxides such as zirconia, alumina or spinel ceramic
• veneering material such as silicate, Verblendkomposite or veneering, especially for dental purposes.
• the invention also encompasses a method for the use of the adhesion promoter in order to produce such a composite material, as well as a kit for the production and application of the adhesion promoter.
• Oxide ceramics are known to be used for the production of highly resilient dental crowns and bridges, it being necessary for the aesthetic design of such prosthetic frameworks the relatively opaque oxide ceramic surface with a tooth-colored dental ceramics, hereinafter called veneering ceramics called (in the form of silicate ceramics, or as Feldspatkeramik or glass ceramic , made of the main components feldspar and quartz).
• veneering ceramics in the form of silicate ceramics, or as Feldspatkeramik or glass ceramic , made of the main components feldspar and quartz.
• the veneering can be done with tooth-colored veneering composite or veneering resin.
• the framework is first milled out with diamond-coated instruments from a pre-sintered oxide ceramic block. This part is about 20% larger in volume than the later framework to be veneered. In the subsequent sintering firing (1250 ° C to 1600 ° C), the framework shrinks to the actual fit.
• the veneering ceramic is applied to this prefabricated and now densely sintered oxide ceramic part and also sintered (850 ° C to 1000 ° C).
• the aim is that the expansion coefficients of both ceramics are identical as possible.
• the expansion coefficient of the veneering ceramic is slightly smaller than that of the framework ceramic, so that during sintering and the subsequent cooling process, the veneering ceramic is shrunk onto the oxide ceramic in the mechanical composite (eg Eichner, Kappert: Zahnêtêt and their processing, volume 2, materials and their clinical processing, Thieme Verlag).
• No. 4,364,731 A describes a method by which a silicon dioxide layer is applied by means of a high-frequency magnetron sputtering apparatus.
• a method is described in DD 276 453, in which a silicate-chromium oxide layer is applied by a sol-gel solution and solidified by a subsequent annealing process (320 ° C, 2-8 min).
• the veneering material is not applied directly to the prefabricated body of densely sintered oxide ceramic, but it is first a passable body made of not yet densely sintered oxide ceramic or their starting materials.
• the base body may be pre-sintered at lower temperatures, but not, as before, densely sintered.
• a primer is applied as a solution or as a sol (slip), which penetrates into the surface of not yet densely sintered body (depending on the use up to 10 ⁇ depth).
• the adhesion promoter consists of a mixture of feldspar and quartz particles in pure and / or processed form, such as silicate ceramics in the mixing ratio of 95:05 to 10:90, and of a suitable dispersant (dispersant), for example water.
• the treated surface of the base body is dried (for example by ambient air or heating) or cured or polymerized.
• the veneering material for example, silicate ceramic or veneering plastic
• the veneering material is applied in a manner known per se to the now densely sintered basic body, in the surface of which the said adhesion promoter previously acted in accordance with the invention.
• the diffused feldspar and quartz particles are incorporated into the oxide ceramic framework.
• a veneering ceramic feldspar ceramic
• a veneering ceramic feldspar ceramic
• the ceramic structures of the veneering ceramic being formed on the one hand become;
• metal-oxygen-silicon bonds between the firmly anchored metal oxides in the oxide ceramic matrix and the silicate in the feldspar ceramic or quartz. Similar to the clinically proven combination of dental alloys and veneering ceramic over decades, this reaction guarantees an additional optimal chemical bond between oxide and veneering ceramics.
• the known methods for increasing the bond strength could not allow such a chemical bond and were therefore on the purely mechanical bond strength of the described shrinkage limited.
• the improved bond between the oxide ceramic and the veneering material not only works with the use of veneering ceramics (silicate ceramics), but also for other veneering materials, in particular veneering composites or plastics.
• adhesion promoters of the type described for the final solution or sol application.
• a kit would be useful with which the starting materials and, if necessary, utensils and instruments are provided for application.
• such a kit could at least consist of:
• At least one container containing a veneering material such as silicate ceramics, for example feldspar,
• At least one container with a dispersant such as water
• An oxide ceramic body pre-sintered at temperatures in the range between 600 ° C. and 900 ° C. (95% ZrO 2 , 5% Y 2 O 3 ) with the dimensions 2 ⁇ 15 ⁇ 15 mm is replaced by a sol consisting of 7.5 g of feldspar, 2 5 g of quartz and 100 ml of distilled water, applied. The application is made by means of a soft brush.
• the sol (water with the solid particles) diffuses into the near-surface region of the oxide ceramic.
• the feldspar and Quartz particles remain there while the water has evaporated after 1 minute.
• the final sintering of the oxide ceramic body After the action and drying of the sol takes place at about 1600 ° C, the final sintering of the oxide ceramic body.
• the veneering ceramic (Zirox) is applied in a layer thickness of 1 mm and sintered as usual in the process at a temperature of 930 ° C.
• a force is exerted by means of pressure shear stress, which leads to a correspondingly high load to the fact that the plastic cylinder is replaced with the Verblendkeramik of the oxide ceramic, however, so that the break always takes place in the veneering ceramic.
• One part of the veneering ceramic remains on the oxide ceramic, the other part on the sheared plastic cylinder.
• the mean value of the measured composite values was 25 MPa.
• the sol (water with the solid particles) diffuses into the near-surface region of the oxide ceramic.
• the feldspar and quartz particles remain there while the water evaporates after 1 minute.
• the final sintering of the oxide ceramic body takes place at about 1450 ° C.

• This silane is used to repair plastic field flakes.
• an optimal chemical Feldspatkeramik plastic composite is made possible.
• the proposal according to the invention additionally achieves a chemical bonding of oxide and veneering ceramic or oxide ceramic and veneering plastic. Under load, the fracture always takes place in the weakest link (in this case, a cohesive failure in the veneering ceramic or a cohesive fracture in the veneering resin), whereas without the procedure according to the invention, the weakest link in the composite combination is the oxide ceramic veneering ceramic interface, with an adhesive fracture behavior.
