Definitions
- the invention relates to blanks for the production of dentures made of zirconium oxide ceramic with an oxidic additive.
- the invention relates to blanks made of zirconium oxide ceramic, to which 0.1 to 0.50% by weight of at least one of the oxides of the elements aluminum, gallium, germanium, indium has been added, for the production of dentures, in particular crowns and bridges.
- ceramic prostheses in the dental field is a desirable goal, since ceramic materials are characterized by high strengths and, unlike metal prostheses, are already in the tooth shade or adopt them after firing. Due to the high tissue compatibility and the lower thermal conductivity compared to metals, ceramics are particularly suitable for dentures.
- EP-A-0 630 622 describes blanks based on zirconium oxide which, in addition to the constituents of hafnium and yttrium oxide which are unavoidable when zirconium oxide is used, contain up to 0.2% by weight of impurities.
- a disadvantage of impurities is the tendency of the ceramic to form glass or glass phases during the sintering process. Impurities therefore ultimately have a negative effect on the strength of the dental prosthesis made from these ceramics and should be avoided at all costs.
- the object of the invention is to provide blanks for the manufacture of unbreakable and precisely fitting dentures.
- blanks comprising ceramics based on zirconium oxide with an addition of 0.1 to 0.50% by weight of at least one of the oxides of the elements aluminum, gallium, germanium, indium are suitable for the production of complex dentures and filigree structures .
- the oxides of the elements mentioned above are preferably present in an amount as defined above with a homogeneous distribution and not, like the impurities, unevenly and with a varying concentration distribution. This homogeneous distribution can be achieved, for example, by co-precipitation as described in the exemplary embodiment of this invention.
- the grain shape of the particles is preferably equiaxial with an average grain diameter of less than 1 ⁇ m, particularly preferably less than 0.7 ⁇ m.
- Blanks according to the invention usually have a pore volume of 50 to 65%.
- the average pore size is usually in the range from 3 ⁇ m to 0.1 ⁇ m, the range from 2 ⁇ m to 0.2 ⁇ m being preferred.
- the blanks according to the invention comprise ceramics containing the components of the composition (1) described below:
- the sum of the% by weight of components (A) to (E) must add up to 100.
- Component (E) of the composition (1) means coloring oxides from elements from the group Pr, Er, Fe, Co, Ni, Ti, V, Cr, Cu, Mn, preferably Fe 2 O 3 , Er 2 O 3 or MnO 2 can be used.
- the blanks according to the invention moreover have a particularly high and uniformly distributed hardness and strength, which makes them outstandingly suitable for use in the production of high-quality dentures by machining blanks in the non-densely sintered state.
- Composition (1) according to the invention can be prepared by dissolving components (A) and (B) of composition (1) contained in commercially available zircon sand with HCl, mechanically separating the sparingly soluble impurities and combining them with oxychloride or treatment after treatment with HCl. Chlorides present additives (C) and (D) as an aqueous, strongly acidic solution.
- Coloring additives according to component (E) are then also added as chlorides, obtained by dissolving in HCl.
- the blanks according to the invention are made from the granules obtained in this way into the desired preform, for example by known pressing methods Brought cylinder. These compacts are debindered by a binder-dependent heat treatment and pre-sintered at a temperature between 850 ° C and 1000 ° C, preferably between 950 ° C and 995 ° C with a holding time of 0.5 to 2 hours.
- the blanks processed using customary methods are densely sintered, for example, at 1200 ° C. to 1650 ° C., particularly preferably 1350 ° C. to 1550 ° C.
- compositions which permit the generation of blanks which do not form any glass phases or glass portions during the dense sintering are therefore given to compositions which permit the generation of blanks which do not form any glass phases or glass portions during the dense sintering.
- the blanks according to the invention also have a preferred deviation from the linearity of the shrinkage per spatial direction, which is less than 0.05%, particularly preferably less than 0.01%.
- K critical stress intensity factor
- This factor is significantly lower for amorphous materials, such as glasses, than for purely crystalline systems (D. Munz / T. Fett: Mechanical behavior of ceramic materials, Springer-Verlag). This means that the strength of ceramics also drops when amorphous phases form at the grain boundaries.
- the ceramics which can preferably be used according to the invention therefore have, for example, a value for K, c of 5 to 10, preferably 8 to 10, determined in accordance with EN 843.
- the disclosed zirconium oxide ceramics can be used with particular advantage in the context of the process described in DE-199 38 144 for producing dentures with pre-sintered blanks.
- the invention therefore also relates to devices which contain at least one blank according to the invention.
- Devices are understood to mean, for example, open or closed blank holders.
- preforms obtained by using pressure are used in the manufacture of these preforms; chlorides are used in the examples.
- Production examples 1 and 2 zirconium oxide ceramics with aluminum oxide content
- the preforms are debindered by a heat treatment (heating rate: 4 K / min to 650 ° C., 1 h holding time) and pre-sintered to the blanks according to the invention at a temperature at 970 ° C. with a 0.5 h holding time.
- blanks produced according to manufacturing examples 1 and / or 2 are processed with a CAD / CAM system by milling or grinding and densely sintered under the following parameters, for example with the aid of a device from DE 199 04 534:
- Heating rate 10 K / min to final temperature: 1500 ° C holding time at final temperature: 2 h
