Definitions
- the invention relates to a method according to the preamble of claim 1.
- Dental prosthetic reconstructions are to be understood as prosthetic tooth inlays, prosthetic tooth crowns and dental bridges, construction elements of all kinds, such as abutments (spacer sleeves) and all kinds of dental technology aids, in particular the framework structures that may still need to be veneered.
- tooth crowns After the tooth defect has been ground down, an imprint of the tooth, the tooth environment and the jaw is made, alternatively the surface of the cavity can also be recorded with computer assistance using stereophotogrammetric scanning devices or laser scanning.
- the desired inlay or crown outer shape is reconstructed using either the data of the tooth recorded and stored before the tooth defect was ground down, and then reconstructed directly from a corresponding block of material, for example a ceramic block, using a three-axis grinding machine , or on the basis of models made of plastic or plaster obtained from an impression of the still untreated tooth.
- Ceramic prostheses which are milled out of a ceramic blank, can - particularly in the tapered edge areas, which must be made extremely thin in order to achieve a seamless transition to the existing tooth - tend to break out due to the treatment. Traces of grinding - which are possible even with fine fibrillation - can lead to the formation of cracks and thus to further risk of breakage.
- US Pat. No. 5,106,303 describes a method in which ceramic powder is compacted or pre-mashed. From this pretreated block of material, the shape for the inlay or the crown is then copied and milled on an enlarged scale, so that the shrinkage which occurs during the subsequent sintering is compensated for and the denture obtained in the prepared cavity or on the prepared tooth stump fits.
- the advantage of this method lies in the fact that the material can be processed in the so-called green stage, which simplifies the processing, since the density and hardness of the material desired for use as dentures can only be achieved by post-sintering. Problems can arise with this method described in US Pat. No. 5,106,303, however, in that during post-smelting, which is carried out at a temperature of approximately 1500 ° C., the very thin marginal areas are deformed or become susceptible to breakage .
- the prosthetic reconstruction produced will have great strength and density with a low proportion. where X-ray opacity is given at the same time, the possibility of choosing the color scheme which is desirable for the overall aesthetic impression.
- oxide ceramics and also other hard materials mentioned above
- compacts produced by various consolidation processes - compacting or pre-sintering initially have a low density or strength and are easy to process in this so-called green state. If the shape and possibly also the work stump or the work pack are thus milled out of such a compact, this is advantageous in terms of work technology.
- the method according to the invention is also and especially advantageous for the production of abutments.
- Intermediate sintered abutments allow any form, however complex, to be prepared during the integration phase of the fixture installation (implant) and then to be sintered, so that - after insertion of the abutments - a direct integration of the crown or bridge is made possible. This is advantageous both from the point of view of labor economy as well as the duration of treatment and the aesthetic demands, which are particularly important when it comes to delicate pillar teeth.
- the material required for the work stump or the work pack is milled out of the compact in powder or chip form, and pressed into the work stump shape or packed around the presintered form of the reconstruction - in particular as a predetermined block shape - this is packed Material in the subsequent post-treatment, post-sintering, in which the required consolidation takes place, is only sintered together to a greater or lesser extent, which after sintering removes or detaches from the inlay or crown shape or from the finished sintered reconstruction or can be radiated or emitted.
- the mold can be provided as a release agent on the inside or on the outside with a thin layer of lacquer, which can be, for example, a zappon or a cellulose lacquer, before inserting the work stump or before packing become.
- lacquer which can be, for example, a zappon or a cellulose lacquer
- FIG. 1a to 1e show a production of an enlarged crown shape
- 2 shows a pretreated compact from which the crown shape and the material for a work stump ßzw. a working pack is produced
- FIG. 3 shows a crown shape sitting on a working stump, as well as a Zann crown obtained after the aftertreatment.
- FIGS. 1 a to 1 e show the production of an enlarged crown shape 2 - exemplary for the production of inlays, individual teeth, bridges, and reconstructions in general.
- a carious tooth 3 After a carious tooth 3 has been ground down, it presents itself as a tooth stump 4, from which an impression 4a is made, which is poured out with a casting material.
- the model 4b thus obtained (corresponds to the ground tooth 4) of the cavity or the tooth situation then serves as the basis for the formation of a wax or plastic model 5 for the crown.
- This wax model 5 is then scanned with a copy milling system 6 - for example via a laser distance device 7 (conventional, manual or optical scanning via a pantograph system or another corresponding system is also possible), the data are m in a computer 9 stored, processed and transferred to a milling spindle 8, enlarged according to the material to be used, which mills the image of the wax model 5, enlarged by the given enlargement factor, out of an oxide ceramic compact 10.
- the intermediate step of producing a wax or plastic model can be dispensed with, and the shape can be modeled directly with computer support. After milling the top of the crown shape 2 (FIG. 2), the inner shape is produced in the same way.
- an impression and the creation of a model can in principle also be dispensed with if the inlay outer shape, cavity shape or prepared teeth are detected directly in the patient's mouth by means of corresponding scanning devices.
- a compact 10 is shown in FIG. 2, which was compacted, for example, at room temperature at about 2000 bar. Chips 11, for example of a length of 2/10 mm, are milled out of the compact 10, for example zirconium oxide ceramic, to remove it.
- the crown shape 2 is produced in the manner described above with reference to FIGS.
- crown shape 2 and chips 11 are now pre-sintered, for zirconium oxide ceramics at approx. 1180 ° C. If necessary, crown shape 2 and chips 11 can also be worked out from a pre-sintered compact 10.
- the processing of the ceramics in the so-called Grünstadiu ⁇ , ⁇ .h. in the non-pre-sintered state, as well as the processing in the semi-sintered (pre-sintered) state, has the advantage over the methods that create the desired dental prosthesis shapes or reconstructions directly from the finished sintered work block that there are fewer micro cracks when processing the ceramic be incorporated into the surface and that the naturally high tool wear that occurs when processing the high-strength materials is reduced.
- the chips 11 are then mixed with water to form a thick paste - resulting in a work stump 12 - and the crown shape 2 is filled in.
- the water added to the chips 11 or the powder grains can contain different admixtures, for example the addition of about 1% acetic acid makes handling the pulp easier, and thixotropic behavior results. Mixing in alcohols, for example the stability or compactness of the mixture increases. The type and amount of the admixtures will therefore have to be provided depending on the desired or required property.
- the lacquer 13 burns without residue, with a minimal gap between the crown shape 2 and the die 12, so that the latter can be easily removed from the crown. Remove nenform 2, or - especially due to the porous consistency - can radiate.
- the crown shape 2 can also be ironed to a predetermined extent from the outside, in order to support the sintering shrinking process in a controlled manner.
- Work pack 14 lie.
- the crown shape 2 is then also coated from the outside with the separating lacquer layer, as described above.
- the work pack which may have been in the form of a block, is then finished together with the crown shape and the work stump which may be arranged therein.
- the sintering process can be controlled precisely using such a work pack, since the change in the external dimensions allows direct control of the shrinking process.
- other forms of reconstruction which may have no or only very small cavities, such as, for example, abutments, may optionally only be sintered packed in the work pack.
- the tooth crown 1 or the framework structure obtained in this way fits exactly onto the prepared tooth 4 (FIG. 1). If desired, it can be veneered in a known manner at approx. 700 DIS 1200 ° C with feldspar ceramic, glass ceramics or zirconium - containing veneering materials in powder form.
- the veneering material must be selected in accordance with the coefficient of thermal expansion of the crown or framework materials, the coefficient of thermal expansion of the veneering materials being in the corresponding range or entirely below it.
- Pretreatment Zirconia alumina not presintered, isostat pressed 30% 20% presintered at 1080 ° C 27% 16% 1100 ° C 26% 15%
- the stump or the work pack can also be formed in one piece, as long as it can be removed from or removed from the crown shape after the aftertreatment, if necessary by means of a separating agent applied therebetween, or even after the heat treatment - or can be emitted.
