    The present invention relates to a dental partial denture having at least one surface for forming a occlusal surface of a posterior tooth.
    Dentistry is increasingly causing problems today. 5 Teeth grinding or bruxism and / or clenching of the teeth cause wear and abrasion of the teeth and especially of the lateral or molar teeth in many patients. Teeth grinding or bruxism and the clenching of the teeth is usually unconscious and often at night and over a longer period of time, which can lead to a significant malposition that overloads the periodontium and additionally the temporomandibular joint, the masticatory muscles but also other muscle groups. which need to be strained to stabilize the head damages. This can lead to severe pain syndromes and ear whistles or tinnitus. Other common symptoms include dizziness, blurred vision and nausea. The 15 pain syndromes are referred to in German literature as craniomandibular dysfunction.
    In the prior art, it is known to use the so-called splint therapy to stop the teeth grinding during the night. For this purpose, between the 20 shaved so already damaged by ablation teeth of the upper and lower jaw rails prepared appropriately inserted, which correct the already occurred malposition again. However, this is only possible overnight, so that the actual cause and the actual problem can not be resolved. 27/02/2013 11:29 ( / 29 R488 P.006 / 032 25 27/02 2013 11:23 FAX +43 5522 73359 Hofmann & Fechner @ 0007/0032 • 0 · · · 0 0 0 0 0 0 0 0 • · · 0 0 0 0 00 0 0 00 0 # 000 0 0 # 000 · 0000 00 0 ··· 0 0 · Π · 0 0 «00 000 00 I 00 2
    The abrasion in the area of the lateral or molar teeth is particularly strong. Here, the original occlusal surfaces are already more or less completely eradicated in many patients. 5 It is already known in the prior art to replace the already missing by abrasion parts of the posterior teeth by means of generic dental partial dentures by putting the dental partial dentures on the side teeth and thus creates an overall higher posterior tooth. The dental partial dentures form at least u.a. a surface for forming the occlusal surface of the 10 posterior tooth. In the prior art, the dental partial dentures required for this purpose are manufactured individually by the dental technician by hand. Particularly complex here is the creation of a nature of at least close coming surface design of the chewing surface, so the recollection of existing in the natural tooth hump and fissures of occlusal surface. In the prior art, the dental partial dentures are made by the dental technician made of metal, such as e.g. Gold, made of ceramics but also of plastic.
    The object of the invention is to provide dental partial dentures of the abovementioned type, ie dental partial dentures for posterior teeth, which can be used particularly simply and inexpensively to remedy the above-mentioned damage.
    For this purpose, it is provided according to the invention that the dental partial denture comprises a composite material, wherein the composite material 25 contains at least one organic binder, preferably methacrylate, and, preferably inorganic, solid particles as a filler.
    The invention is thus based on the basic knowledge that with the said composite material, a relatively inexpensive manufacturable and especially 30 universally replaceable partial denture can be created, which has at least one surface for forming a chewing surface of a posterior tooth. The said composite material convinces in use by its for the 27/02/2013 11:29 V.19.

    Field of application excellent physical properties but also by its easy applicability to the respective abrasion-damaged posterior tooth. It has surprisingly been found that dental partial dentures according to the invention with the said composite material and 5 are permanently stable so that they permanently withstand the occurring in the lateral or molar region during chewing, very high forces. By dental partial dentures according to the invention, which, as described in more detail below, are particularly easy to apply, it is possible to quickly but then permanently fix the abovementioned, caused by abrasion of the posterior teeth problems in the application.
    Particularly preferred embodiments of the invention provide that the dental partial dentures are prefabricated, ie prefabricated, partial dentures. These prefabricated products have at least one surface for forming the chewing surface of the posterior tooth. In addition, they can also have more or less long side walls. They may be in the form of a hollow crown, in which the side walls enclose a cavity of the hollow crown and are formed for reaching down to the gums of the patient. These hollow crowns are used in particular when only one tooth stump is left of the posterior tooth or the other
    The posterior tooth can only be placed on an artificially implanted implant. By contrast, if the side teeth to be supplied are shortened by the abrasion only in their vertical extension, then the dental partial dentures can also be designed shell-like. With these trays, if they are present, then the sidewalls will not reach the gums. The optionally present side walls are thus provided or formed in these cases at most incomplete to descend to the gums of the patient. The more than flat shell-like structures formed dental partial dentures, in which the side walls do not reach down to the gums, can also be referred to as onlay or overlay. The composite material is also often referred to as composite. 27/02/2013 11:30 4/29 R488 P.008 / 032 27/02 2013 11:24 FAX +43 5522 73359 Hofmann & Fechner 12) 0009/0032 ·· «· · ············································································· # ·· t · · fl · · · · · · · ······ §§ ♦ 4
    It has been recognized that it is sufficient to provide for the treatment of the posterior teeth sets with appropriately prefabricated dental partial dentures. Such a set can each have at least one prefabricated, ie prefabricated, dental partial denture for each posterior tooth in three different 5 sizes in order to be able to treat or veneer more or less, all or at least most natural tooth forms occurring in the patient.
    In order to form the surface for forming the chewing surface of the posterior tooth of the dental prosthesis as close to natural as possible to a natural tooth, preferred variants provide that the surface has humps and fissures running between the humps for the formation of the occlusal surface. The arrangement of the humps and fissures is favorably oriented to the natural models. To make the dental partial denture for daily chewing 15 particularly durable and stable, see particularly preferred
    Embodiments of the invention that at least the surface for forming the occlusal surface of the dental partial denture at least partially, preferably completely, is formed by a layer having fused solid particles together. This merging could also be referred to as sintering 20. This can be realized only for the surface for forming the occlusal surface or for the entire outwardly facing surface of the dental partial denture. It is particularly preferred in this context that the layer is formed exclusively of solid particles fused together. The layer of fused solid particles 25 may conveniently be formed as a continuous melt layer. The solid particles fused together are advantageously completely melted during the production of said layer, so that in the cured layer the solid particles are no longer individually recognizable. If, as provided in preferred embodiments and as discussed below, the solid particles are glass or a mixture of different types of glass, said layer forms one, preferably 27/02/2013 11:30 2 / .29 R488 P .009 / 032 27/02 2013 11:25 FAX +43 5522 73359 Hofmann & Fechner @ 0010/0032 * · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·································· , glazed surface, which makes the latter particularly stable and durable.
    Particularly preferred variants of the invention provide that at least the surface for forming the occlusal surface, preferably the entire outwardly facing surface of the dental partial denture, is at least partially laser-treated. Thus, a method can be provided in which at least the surface for forming the occlusal surface, preferably the entire outwardly facing surface of the dental partial denture, is treated by means of laser irradiation. In the case of this laser irradiation, it is preferable to burn off the organic binder in the region of the surface mentioned and to melt and melt together the solid particles, so that the result is preferably a continuous melt layer which at least substantially, but preferably completely, results in and / or 15 completely melted solid particles is formed.
    The dental partial dentures according to the invention are preferably designed radiopaque. In order to create an antibacterial surface in the area of the chewing surface, particularly preferred variants of the invention provide that at least 20 has the surface for forming the chewing surface zinc and / or fluorine components in the solid particles. Overall, an inorganic surface can be formed therefrom in which no organic material, that is to say no organic binder, is also present. In particular, it is favorable if the solid particles of the filler comprise or consist of glass, preferably a mixture of different types of glass. The types of glass can be silanized and differ both in their color and in their composition. For example, it is conceivable to use barium glasses or strontium glasses or mixtures thereof. Generally, it may be surface-treated SiO 2. To a high strength of
    To achieve Zahnfrontverblendungskörpers, it is convenient, the solid particles of the filler in a dense as possible packing in the dental front facing body 271/2/2013 11:25 FAX +43 5522 73359 Hofmann &; Fechner @ 0011/0032 • · · · · · »· · # 9 · · · * · «ft 99 99 M9 99 9 99 6 to be arranged. For this purpose, it is favorable if the filler has solid particles with mutually different particle sizes. Generally speaking, preferred embodiments provide that the particle sizes of the solid particles of the filler are in a range between 0.01 μm and 50 μm. In order to achieve the highest possible packing density, but especially the small grain sizes are important because they fill the spaces between the larger grains. In this sense, it is advantageous if the filler has solid particles with particle sizes between 0.01 pm and 3 pm. In terms of strength, the aim is also to achieve the highest possible degree of filling of the composite material of the toothed facing body. The proportion of the solid particles of the filler in the composite material should therefore be as high as possible.
    Preferred embodiments provide in this context that the volume fraction of the solid particles in the composite material is at least 78%. Preferably, this volume fraction of the solid particles is outside the optionally present layer with the melted or melted
    Solid particles ranging between 78% and 85%. In the layer from or with ver-resp. of melted solid particles, this volume fraction of the material of the solid particles is of course still higher and goes against or reaches 100%. For the sake of completeness, it should be noted that the solid particles, apart from the possibly present layer in which they are fused or merged, are incorporated in the composite material in the organic binder and held together by this.
    As organic binders, preferred embodiments of the invention use methacrylate-based binders. These may consist of methacrylate or methacrylate, preferably as a main component having.
    As a composite material for the production of the dental partial denture, e.g. the product sold under the name REF 2061 by Indigodental 30 GmbH & Co. KG, in Pinneberg, Germany. This product contains triethylene glycol dimethacrylate, urethane dimethacrylate, Bis-GMA and 27/02/2013 11:32 7/29 N .. R488 P.011 / 032 27/02 2013 11:26 FAX +43 5522 73359
    Hofmann & Fectiner @ 0012/0032 • ethoxylated bisphenol A dimethacrylate. As an organic binder, e.g. the product REF 2050 of this company can be used.
    An important task when fitting the dental partial dentures to the posterior teeth is to design the coloring of the partial denture in such a way that it is adapted to the conditions in the patient's mouth and above all to match the color of the remaining natural tooth substance. Preferred embodiments of the invention provide that the dental partial denture standardized has a color that approximates the color of natural enamel 10. It is particularly preferred in this sense that the dental partial denture for visible light is translucent or translucent, that is not opaque. One idea is to make the color matching by using a respective suitably colored fastening material, which is arranged during the attachment of the dental partial denture between this and the tooth 15 or tooth stump and through the translucent partial denture, and so the final, outwardly noticeable color of the whole construction coins. Investigations have shown that the partial dentures favorably have a translucency of 28% to 39% and / or an L value of 59 to 69 and / or an a value of -0.35 to -3.2 and / or a b Value from -0.4 to -6.95 20. The translucency is the translucency, ie the reciprocal property of opacity. The values mentioned relate to a measurement in accordance with DIN 6174. The Lab color space is also known in the prior art. It is constructed on the basis of the counter color theory and allows the colorimetric determination of color measures and color distances in the approximately uniform CIELAB color space. The determination of the L value, the a value and the b value is likewise carried out in accordance with the specifications of DIN 6174. In application of the counter color theory, green and red are located opposite one another on the a axis. The b-axis corresponds to the opposite colors blue and yellow. The L-axis is perpendicular to this plane and reflects the brightness.
    Conveniently, the same composite material is used as the fastening material, from which also the dental partial denture, apart from the FAX +43 5522 73359 11:32 l! R488 P 012/032 30 27/02 2013 11:27 FAX Hofmann & Fechner ®0013 / 0032 • · · · · · · · ·
    8 optionally existing fused or molten or sintered layer is formed. As dyes, in particular for coloring the attachment material, e.g. organic pigments and / or inorganic whiteners such as TI02 can be used. 5
    Due to their high strength, the dental front facing bodies can be made relatively thin. Preferred variants provide that the dental partial denture in the region of the surface for forming the chewing surface of the posterior tooth has a thickness between 0.3 mm and 0.6 mm. The thickness of the dental partial denture in the region of the side walls is favorably between 0.1 mm and 0.25 mm.
    For application of the dental partial denture, the user can use this prefabricated product by first, as far as necessary, the tooth to be veneered or its tooth stump 15, as far as necessary processed or zuschleift as far as necessary in a previously known manner and with a etches suitable etchant to etch away the smear layer caused by drilling or grinding and expose the tubules. Suitable etchants or etch gels are e.g. 15-37% phosphoric acids or the product REF2052 of the company already mentioned above. On the etched side tooth 20 is then preferably a bonding agent so applied a so-called bonding. It is also conceivable to use already finished mixtures of etchant and adhesion promoter. In general, the adhesion promoters or the bonding may be low molecular weight methacrylates. Monomers may also be used which have a hydrophilic or hydrophobic end, e.g. 25 methacrylated polyacrylic acids. As adhesion promoters, e.g. the products designated REF 2050 and REF 2051 of the above-mentioned Indigodental GmbH & Co KG can be used. The product REF2051 is a BIS-GMA based methacrylate. The fastening material can then be applied to the layer of adhesion promoter. Due to the amount of attachment material, the height of the dental partial denture can be adjusted above the shaved posterior tooth. The more fastening material is introduced under the dental partial denture or in its cavity, the larger 27/02/2013 11:33

Between the fastening material, which is preferably the same material as the composite material, and the dental partial denture, a layer of adhesion promoter 5 is preferably applied once again. By coloring the mounting material and / or the
    Adhesion promoter is favorably, as already stated, the color design of the overall structure and thus controlled the color appearance of the fully applied dental partial denture. The mounting material is conveniently in a pasty form. As is known per se, an LED lamp which is mentioned below again or the like can be used to cure the fastening material. The shrinking process occurring during curing of the fastening material can be compensated or absorbed by the bonding agent. By a correspondingly high degree of filling, ie a correspondingly high volume fraction of solid particles in the fastening material or in the composite material, however, a relatively low shrinkage generally occurs during curing.
    To assist the user, e.g. The dentist, apart from his normal equipment, to provide all the tools needed for the treatment, 20 provides a preferred embodiment of the invention, a set with a plurality of prefabricated, in particular different sized and / or differently shaped, dental partial dentures according to the invention. The set may additionally, preferably, liquid or pasty, mounting material and optionally have different colors for coloring the mounting material with. Just as well, it is of course possible to provide several already colored, preferably liquid or pasty, fastening materials in a set. The set can also include suitable etchants and / or adhesion promoters or bonding with. This ultimately makes it possible for the user or dentist to select from the dental partial dentures made available to him from the set that size 30 which comes closest to the natural situation on the posterior tooth tooth or tooth stump to be treated. The remainder of the adjustment can then be made by working or grinding this partial denture in situ. 27/02/2013 11:34 lil ί 29R488 P.014 / 032 27/02 2013 11:28 FAX +43 5522 73359 Hofmann & Fechner @ 0015/0032

Furthermore, the dentist, if present, choose the appropriate color or the appropriately prepared mounting material, with which he attached the dental partial denture on the posterior teeth 5 and its tooth stump, preferably adheres, so that the desired color of the then on the posterior tooth or its tooth stump attached partial denture is achieved.
    A method for producing dental partial dentures according to the invention from the 10 e.g. Commercially available and initially mentioned composite material can provide the following steps:
    First of all, the composite material or composite, with the organic binder and the solid particles, can be filled into cartridges 15 for preparation and heated to about 100 ° C., whereby the material can be softened for subsequent further processing. The composite material can then be pressurized at 80 to 100 bars. Specifically pretreated in this manner, the composite material is injected into a, preferably at least one sided, light-transparent tooth shape. The tooth forms e.g. can be made of glass and chrome steel. To cure the composite material in the tooth form, the composite material can be heated to about 130 ° Celsius and thermally cured for about 15 minutes at this temperature. In addition, preferably, at least for part of this time, e.g. 25 during the first 10 of these 15 minutes, also curing by application of light through the light transparent areas of the tooth shape carried out. This can e.g. be carried out with a suitable LED light. A suitable LED light is e.g. characterized by a wavelength of 450 nanometers (nm) to 480 nm. With the light treatment, the illuminated surfaces can be improved in their properties by polymerization shrinkage. As a result, the solid particles are brought closer together on the illuminated surfaces. During curing, the compound is compounded 27/02/2013 11:34 11/29 R488 P. 015/032 27/02 2013 11:29 FAX +43 5522 73359 Hofmann & Fechner ®0016 / 0032 • · · · · · · · · · · · · · · · · · · · · · · I ··································
    Material in the tooth mold preferably maintained under a pressure between 80 to 100 bar, resulting in a good compression of the entire material in the tooth form. In support of the described thermal cure, thermal initiators suitable as additives may be used, e.g. 5 benzopinacol or 2,2'-dialkylbenzopinacol or suitable photoinitiators, e.g. Benzophenone, benzoin or derivatives thereof are used. Thereafter, the dental partial dentures, preferably gradually, cooled and removed from the tooth shape. The dental partial dentures can be placed in a container with nitrogen atmosphere to avoid oxidation of the organic binder 10. Particularly favorable variants then provide that laser light processing takes place at least on the surface later forming the chewing surface or on the entire, outwardly facing surface of the dental partial denture. The laser light can penetrate, for example, 80 microns deep into the material. In the laser processing of the facial surfaces, the organic binder on the treated surface of the partial dental prosthesis is removed and the solid particles are fused together and then, upon completion of the laser treatment, form a continuous cured enamel layer as the surface of the dental partial denture. This hardened or vitrified melt layer can be detected in a section through the dental front veneering body and preferably has thicknesses of between 20 and 40 micrometers (pm). Subsequently, cutting or reworking, such as Grinding or other smoothing of the dental partial denture done. Further features and details of preferred embodiments of the

The situation is shown in each case before the dental partial dentures 1 are placed on the posterior teeth 3 to be restored. The difference between the embodiment as a hollow crown 10 and as a shell 13 or as an onlay or overlay lies substantially in the presence and / or in the length of the side walls 12. In the case of the hollow crown 10, its side walls 12 extend to the gums when fully applied of the patient, while in the variant in which the dental partial denture 1 is designed as a shell 13, in the finished applied form, as shown in Fig. 1, between the side walls 12 and the gum still a piece 25 of the original posterior tooth 3 out.

The much larger design of the cavity 11 has the advantage that one has relatively much leeway in the correct alignment of the dental partial denture 1 and this is not mandatory from the position of the implant 15 18 mandatory. This may cause errors in the orientation of the
    Implant 18 can be corrected in a simple manner. Analogously, the procedure is also favorable if tooth stumps are supplied by means of hollow crowns 10, as shown in FIG. 4. Again, the cavity 11 is conveniently a lot larger than the remaining tooth stump. 20
    FIG. 13 also shows an enlarged and schematized section through the composite material 4 and the layer 7, which is arranged peripherally and forms the surface, of fused solid particles 6 of a dental partial denture 1. Here, too, the volume ratios are not reproduced exactly , it is easy to see how the solid particles 6 are embedded in the organic binder 5. The layer 7 of molten solid particles 6 is desirably free of binder 5. It can be made well visible in reality in a corresponding section through a corresponding dental partial denture 1. 27/02/2013 11:37 16/29 No .: R488 P.020 / 032 30 27/02 2013 11:32 FAX +43 5522 73359 Hofmann & Fechner ®0021 / 0032 * · · ♦ · ···········································································

    In the following, it will be explained by way of example how the dental partial dentures 1 according to the invention are applied to side teeth 3 to be treated correspondingly, that is to say they can be attached. In a first variant, the side teeth 3 to be supplied are first prepared according to the prior art and etched by means of etchant.
    Subsequently, the adhesion promoter 15 or the bonding is applied to the side teeth 3 thus prepared. The matrix bands 14, which are shown in FIG. 4 and are known per se, can then be fitted around the posterior teeth 3 to be supplied. With the aid of the matrix bands 14, the interdental and buccal and lingual tooth forms can then be reconstructed in a plurality of layers consisting of fastening material 16. Instead of, as known in the prior art, to model the occlusal area, that is to say the occlusal surface, by hand, the dental partial dentures 1 according to the invention are provided basally with adhesion promoter and applied to the fastening material. The fastening material can then be fixed by means of a polymerization lamp, with which the dental partial dentures 1 are fixed on the respective side tooth 3. The fastening material 16 then lies in a kind of sandwich position, such as e.g. in Fig. 5, between the prefabricated dental partial denture 1 and the posterior tooth 3. After curing of the
    Fixing material 16, the matrix bands 14 can be removed. If necessary, the reconstruction thus created can be finished with rotating grinders or the like, as they are known for dental supplies. The occlusions so the correct edition in the bite position of the 25 chewing surfaces forming surface 2 can then reoccluded, so be processed by grinding final, as far as this is necessary and until the desired Kontaktpunlcte are achieved. This can be monitored or colored by means of ordinary contact point films as known in the art.
    Another type of application of the dental partial dentures 1 on the posterior teeth 3 to be veneered provides that initially, as is known, by means of P.021 / 032 17/29 27/02/2013 11:38 no .: R488 30 27 / 02 2013 11:32 FAX +43 5522 73359 Hofmann & Fechner @ 0022/0032 M ····· MM ·· «······ ··· ···································· I ···· ·· Mt M · ·· 17
    Impression or similar models of pre-treatment situation in the upper and lower jaw are made. These upper and lower jaw models can then be articulated in an articulator in accordance with the skull in a manner known in the art. The situation in the articulator can then be adjusted by adjusting the articulated upper and lower jaw models relative to each other, as is to be achieved in the patient with the use of the dental partial dentures 1 at the end of the treatment. This creates gaps in the articulator between the upper and lower jaw models, which reflect the tooth substance lost by abrasion of the natural posterior teeth 10 3. It can now be in the area of
    Posterior teeth bite splints in a manner known per se, e.g. be created from plastic, which fill these gaps between the upper and lower jaw model and the corresponding side teeth 3. These bite splints thus produced may be applied to the abraded posterior teeth 3 for testing in the patient and there for a period of time, e.g. a week to test whether initially with the bite splints the desired new position of upper and lower jaw is actually achieved relative to each other. If this test indicates that a readjustment is still necessary, the bite splints can be correspondingly, e.g. by sectioning, reworked until the optimal position in the patient's mouth is achieved.
    If a corresponding revision of the bite splints is carried out, a corresponding readjustment of the position of the upper and lower jaw model relative to one another takes place in the articulator as far as necessary by means of the revised bite splints. If the position of upper and lower jaw model is finally achieved relative to one another in the articulator, the interspaces between the upper and lower jaw model articulated in the articulation are, if appropriate after removal of the occlusal splints, poured out in the region of the posterior teeth 3 by silicone, in order thus for both posterior teeth areas To produce bite registration body.
    These are then shaped so that when the patient bites on them with the 30 posterior teeth, the patient's upper jaw and lower jaw will move into position relative to each other, as at the end of the treatment, according to the finished 27/02/2013 11:39 18 / 29 wr. : R488 P.022 / 032 27/02 2013 11:33 FAX +43 5522 73359 Hofmann & Fechner @ 0023/0032 ·········································································· ··············· M ····· · ·

    Application of the dental partial dentures 1 according to the invention to the naturally existing posterior teeth 3 is to be achieved.
    The bite registration bodies produced in this way can subsequently be used in different ways and for the application of the dental partial dentures 1 on the posterior teeth 3.
    In one of these uses it is provided that the corresponding Bissregistrierkörper is arranged in the articulator between the upper jaw and lower jaw model 10 on one side between the corresponding side teeth. On the other hand, prostheses are then created on the posterior teeth of the upper and lower jaw model to be treated, first with the fastening material 16 and then resting on it with the partial dental prosthesis 1, which after its completion and, if appropriate, corresponding grinding then at 15 patients at the appropriate location on the respective Side tooth 3 only need to be glued on. The exact height of the dental partial dentures 1 on the respective side teeth 3 can be adjusted by appropriate opening and closing of the articulator. In this case, the compression of the not yet solidified fastening material 16 can come from the cavities 10 of the respective dental partial denture 1. This can then be sanded off after hardening of the fastening material 16, however. The curing of the fastening material is carried out in accordance with LED light, as described above. If one side has been completed accordingly, the bite registration body can be removed in order then to process the other side accordingly. In this variant, the dental partial dentures 1 can be used in their prefabricated form so that on the corresponding articulated upper and lower jaw models by the dental technician first for each patient situation by relining the respective partial denture 1 with the appropriate amounts of mounting material 16 exactly 30 matching prostheses be created by the dentist in the mouth of the patient only on the posterior teeth 3 and if necessary must be ground for Reokklusion. 27/02/2013 11:39 19/29 No.: R488 P.023 / 032 27/02 2013 11:34 FAX +43 5522 73359 Hofmann & Fechner 00024/0032 »» ·· # »t ··« · # · ♦ · «··· • ···················································································· · ♦ · · · ff ·· ffffff ffff · ·· 19
    Another variant of the application of the prefabricated dental partial dentures 1 according to the invention provides that one of the Bissregistrierkörper manufactured as described above are arranged directly on one side in the patient's mouth between the 5 corresponding side teeth 3 of upper and lower jaw and on the other side to be supplied to the side teeth 3, optionally after an etching of the teeth, first by means of adhesion promoter 15 and mounting material 16 and resting thereon by means of the prefabricated dental partial dentures 1 are constructed. The dentist realized in this variant 10 ultimately the same procedure, as previously described by the dental technician on the articulator, only in this variant just directly in the mouth of the patient. The exact alignment of the dental partial denture 1 can in turn be achieved by simply biting, since it is predetermined by the Bissregistrierkörper. The curing of the mounting material 16 is again by means of LED lamp. After curing, again in situ, if necessary, finishing can be carried out by means of grinding for re-occlusion.
    The first and the last-mentioned embodiment variant have the advantage that the application of the prefabricated dental partial dentures 1 in the mouth of the patient 20 can be performed directly and cost-effectively in a single session by the dentist directly.
    In summary, it should be noted that the dental partial dentures according to the invention allow a very rapid and cost-effective user-friendly handling 25 and have excellent processing properties. These are u.a. also the easy and quick polishability and the low shrinkage during the curing process due to the high degree of filling of solid particles. The dental partial dentures 1 according to the invention have an excellent abrasion behavior and very good physical properties. By the above-mentioned zinc and fluorine components in the solid particles 6 in addition, an antibacterial effect of the surfaces can be achieved.
