    专利说明:

    The invention relates to a blank for producing a dental element (eg a dental model or a dental replacement part) having a first side, a second side and at least one main holding surface spaced from the second side for holding the blank on a holding device, wherein the blank has a standard holding thickness between the main holding surface and the rear side.
    Such a blank according to the prior art is apparent from the Fig. 1 a to 2c, which are described in detail below.
    Fig. 1 a shows a holding device 3 for a blank 1,2, as it has been manufactured for some time by the Applicant, offered and sold. Such a holding device has a substantially C-shaped carrier 12, on which the drive motors 13 and 14 are arranged. On the support 12, the outer retaining ring 11 is rotatably mounted. In turn, the inner retaining ring 10 is rotatably mounted on this outer retaining ring 11. In the inner retaining ring 10 can be clamped on the clamping device 6 and its clamping parts 7 of the blank 1.2, wherein the clamping parts 7 in Fig. 1 a are in a passive position P. In Fig. 1 a is indicated by the arrows on a sectional axis, wherein the corresponding section is shown in Fig. 1b. It can be seen that the blank is 1,2 inserted into the inner retaining ring 10 and rests on a clamping surface 8. The blank 1,2 has a first side (corresponding to a front side V) and a second side (corresponding to a rear side R).
    In order to hold the blank 1.2 to the holding device 3, the clamping parts 7 are rotated about the clamping bolt 15 of the clamping device 6 as shown in FIGS. 2a and 2b, whereby the clamping parts 7 reach a clamping position K. In this clamping position K, the blank 1, 2 is clamped over the main holding surfaces Ki formed on the blank 1, 2 and the rear side (R) between the clamping surfaces 8 and the clamping parts 7 of the clamping device 6. The blank 1,2 has a standard holding thickness D-1 between its rear side (R) and each main holding surface K-i. In a preferred embodiment, this standard holding thickness Di is 10 mm. In Fig. 2c, the holding device 3 together with clamped blank 1.2 is shown in a 3D view. There are also the axes of rotation for the two retaining rings 10 and 11 can be seen.
    These known from the prior art blanks are processed in holding devices in a time-tested manner, whereby dental spare parts are manufactured.
    The object of the present invention is to provide a comparison with the prior art modified or improved blank. In particular, the blank should be more versatile. In addition, the work should be simplified for a user. Furthermore, the workload should be reduced. Especially should be possible with as few steps, the production of several dental elements.
    This is achieved by a blank having the features of claim 1. According to the invention, the blank has at least one auxiliary holding surface spaced from the second side for holding the blank to a holding device, wherein the blank has a special holding thickness between the at least one auxiliary holding surface and the second side, wherein the standard holding thickness is greater than the special -Haltedicke. This makes it possible that in one and the same holding device either a single blank is clamped over the at least one main holding surface or two blanks are simultaneously clamped in the same holding device via the respective narrower auxiliary holding surfaces. As a result, dental elements can be worked out from two different blanks after a single fastening operation, without having to perform a re-tightening or a new tightening between them. In general, the at least one narrower special holding thickness thus facilitates the holding of two such blanks in one and the same holding device.
    Protection is also sought for a set according to claim 12. Accordingly, it is provided that the special holding thickness of the first blank and the special holding thickness of the second blank adds the standard holding thickness results. This allows for a
    Holding device provided two mutually different blanks, but still fit into an unchanged fixture. For example, it may thus be provided that special holding thickness of a blank is about 7 mm, while the special holding thickness of the other blank is about 3 mm, so that the overall standard holding thickness results again when two blank are clamped corresponding to each other , For a simple mass production, however, it is preferably provided that the standard holding thickness is twice as large as the special holding thickness. In a specific embodiment, this means, for example, that the special holding thickness is always 5 mm. Of course, larger or smaller millimeter dimensions are possible as long as sufficient support is guaranteed and the blanks can be clamped in the fixture. For a simple attachment of the blank to the holding device is preferably provided that a plurality, preferably three, main holding surfaces regularly, preferably in each case by 120 °, spaced from each other formed on the blank. Furthermore, it is advantageous if a plurality, preferably three, auxiliary holding surfaces are formed on the blank regularly, preferably at 120 ° from each other. In order to ensure sufficient space for holding on the blank, it is preferably provided that the main holding surface and the auxiliary holding surface are spaced from each other formed on the blank. It can be provided that the plurality of main holding surfaces and the plurality of auxiliary holding surfaces from each other regularly, preferably in each case by 60 °, spaced formed on the blank.
    In itself, the shape of the blank is arbitrary. Thus, the blank can, for example, be cuboid, jaw-shaped, diced or formed in a similar manner. Particularly preferably, however, it is provided that the blank is disc-shaped and has the substantially planar first side, the substantially planar second side parallel to the first side and a substantially perpendicular to the second side and the first side oriented peripheral surface.
    In principle, the main holding surface and also the auxiliary holding surface can be formed, arranged and aligned as desired on the blank, as long as these surfaces mate with the corresponding mating surfaces of the clamping device. In the case of a disc-shaped blank, however, it is preferably provided that the at least one main holding surface and the at least one auxiliary holding surface are aligned parallel to the first side and to the second side. Preferably, the standard holding thickness and the special holding thickness are each measured parallel to the peripheral surface.
    If the blank is disc-shaped, it is particularly preferred that the peripheral surface is substantially circular-cylinder-jacket-shaped. Of course, deviations from the circular cylinder jacket shape can be given in some areas. In particular, it is provided in particular that the at least one main holding surface and the at least one auxiliary holding surface are formed in the form of recesses in the first side and peripheral surface. Preferably, the peripheral surface of the blank in the area outside the recesses is formed entirely circular cylinder jacket-shaped.
    However, the invention relates not only to a concrete blank, but also to an arrangement with two blanks and a holding device for holding the two blanks, wherein the two blanks each have a front side formed as a first side and a second side designed as a back.
    Such a holding or clamping of two blanks in a workbench insert (holding device) is described in DE 10 2010 061 116 A1, and in particular from FIG. 9.1 d. The two clamped blanks abut each other via a contact surface. The disadvantage is that these blanks are clamped over a large part of the front and rear sides in the work table insert. Thus, only a small protruding area is even editable.
    It is therefore another object of the present invention to provide an arrangement which enables simple and effective machining of two clamped blanks.
    This is achieved by an arrangement having the features of claim 11. Accordingly, it is provided that in the clamped state, the two blanks with the rear sides facing each other and substantially the entire front sides of the blanks are accessible. As a result, it is no longer necessary to re-clamp or otherwise use the blanks in order to work out the desired dental elements from as far as possible the entire blank. "Essentially the complete front pages" means that (seen in a plan view) at least 80%, preferably at least 90%, particularly preferably at least 95%, of the front sides are freely accessible in the clamped state for a processing device.
    In such an arrangement, the holding of the two blanks can be done in any way, as long as the two front sides are completely accessible. Preferably, however, it is provided that both blanks have at least one auxiliary holding surface spaced from the rear side for holding the blank on a holding device, wherein the blank has a special holding thickness between the at least one auxiliary holding surface and the rear side and wherein the standard holding thickness is twice as large how the special holding thicknesses are. For a simple clamping of the two blanks is preferably provided that the holding device has at least one, preferably three, clamping device, wherein the blanks are clamped on their auxiliary holding surfaces of de clamping device on the holding device. In a concrete embodiment, it is further provided that - in the case of several clamping devices - each clamping device has a movable clamping part and a clamping surface, wherein in the clamped state, an auxiliary holding surface of a blank rests on the clamping surface and abuts an auxiliary holding surface of the other blank on the clamping part. Of course, the same jig can also clamp a single blank over the main support surface and the back.
    In principle, it is possible that the clamping device is suitable to clamp different thickness blanks. Thus, the clamping device can have mutually adjustable clamping parts and clamping surfaces. Preferably, however, it is provided for a simple design that the movable clamping part and the clamping surface of the clamping device to each other have a substantially invariable, preferably the standard holding thickness corresponding distance. Thus, both a blank and two blank can be clamped in one and the same, simple clamping device. For ease of manufacture, storage and use is preferably provided that the two blanks are identical.
    Basically, the blanks do not have to touch each other when clamped over their backs. For a simple hold without any intermediate piece but is preferably provided that the blanks in the clamped state over the mutually facing backs partially or completely abut each other.
    According to a further preferred embodiment, such an arrangement also has a processing device for processing the two blanks clamped in the holding device, wherein both blanks can be processed by the processing device via the substantially completely accessible front sides. Thus, the processing device and the holding device are relatively movable relative to each other, that both front sides are machined.
    Protection is also desired for a method of clamping two blanks of the invention on a fixture. In this case, the steps of inserting a first blank into the holding device, the first blank resting on at least one auxiliary holding surface on a clamping surface of a clamping device of the holding device, inserting the second blank in the holding device, wherein the blanks face each other with their respective backs and at least an auxiliary holding surface of the second blank is aligned with the at least one auxiliary holding surface of the first blank and moving the clamping part of the clamping device of the holding device from a passive position to a clamping position, so that in the clamping position, the clamping part rests against the at least one auxiliary holding surface of the second blank and both blanks are clamped or clamped together on the respective auxiliary holding surfaces between clamping part and clamping surface of the clamping device of the holding device.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:

    13a to 16c an alternative embodiment of a holding device with one or two clamped blanks.
    FIGS. 1 a to 2 c, which show the prior art, have already been discussed in more detail in the introduction to the description.
    In Fig. 3a in a side view of the substantially circular cylindrical shell-shaped peripheral surface U of a blank 1.2 is shown. In this circular cylinder jacket-shaped peripheral surface U more recesses 4 are present. Through these recesses 4 parallel main retaining surfaces K-i and auxiliary retaining surfaces K2 are formed on the blank 1,2 to the front V and R back. In addition, at the same time, a part of the second side (corresponding to the rear side R) also forms counter-holding surfaces G (see FIG. 3g). The main holding surfaces Ki in the region of the recesses 4 and the rear side R are each spaced from each other by the standard holding thickness D-ι. In the area of the auxiliary holding surfaces K2, the blank 1,2 has the special holding thickness D2 as the distance to the rear side R. The special holding thickness D2 is smaller, preferably half as large as the standard holding thickness D-ι. FIGS. 3b to 3g again show the same components or surfaces. FIGS. 3 a to 3 g also show the at least one positioning groove 16, by way of which the blanks 1, 2 are clamped at a suitable point in the holding device 3. This also guarantees that when clamping two blanks 1, 2, the auxiliary holding surfaces K 2 of the two blanks 1, 2 are correctly positioned relative to each other - that is, axially opposite one another. Alternatively, it is also possible to realize a positioning via the position bores 19 formed in the rear side R.
    Fig. 4a shows a holding device 3, which has an inner retaining ring 10, an outer retaining ring 11, a preferably C-shaped support 12 and two drive motors 13 and 14 for the two retaining rings 10 and 11. In the inner retaining ring 10 are - as shown in Fig. 4b - the two blanks 1 and 2 used. The first blank 1 rests on the clamping surfaces 8 of the clamping device 6 via its auxiliary holding surfaces K2. The tensioning device 6 is formed by the clamping surfaces 8, the clamping parts 7 and the clamping bolt 15. In Figs. 4a and 4b, the clamping parts 7 are still in the passive position P.
    In contrast, the clamping parts 7 were pivoted about the clamping bolt 15 in the clamping position K according to FIGS. 5a to 5c. As a result, the clamping parts 7 rest on the auxiliary holding surfaces K2 of the second blank 2. Since the first blank 1 according to FIGS. 4b and 5b already bears against the clamping surface 8 of the inner retaining ring 10, both blanks 1 and 2 are clamped simultaneously by the tensioning device 6 on the holding device 3. Because the special holding thickness D2 of the two
    Blanks 1 and 2 added the standard holding thickness Di result, can - in the same manner as a single blank 1.2 is clamped over the main holding surfaces Ki and the back R - both blanks 1 and 2 are clamped on the respective auxiliary holding surfaces K2. Thus, without having to make a change to the holding device 3, a more efficient use can be made by two blanks 1 and 2 are clamped simultaneously. Between the processing of the two blanks 1 and 2 must be done by no re-clamping.
    In order to simplify the processing of the blanks 1 and 2 for a dental technician, the blanks 1, 2 according to FIGS. 6a to 6g can be pre-machined or pre-routed. In particular, blanks 1, 2 (blocks) are formed so that the remaining geometry is modeled on a bit. This has the advantage that it is no longer necessary to cut the complete block. The cutouts 17 thus no longer need to be incorporated by a device at the dental technician, but are already delivered with cutouts 17. The bit-shaped inner region of this blank 1, 2 is connected to the outer region by connecting webs 18.
    7a shows an arrangement 5 with a holding device 3, two blanks 1 and 2 clamped in the holding device 3 and a processing device 9. This processing device 9 can have a spindle, as shown in FIG. 7b. At the front of the spindle, a milling cutter or the like may be arranged to machine the individual blanks 1 and 2 successively from the front side V, respectively. For this, the inner retaining ring 10 can rotate at least by 180 °, preferably complete 360 °, about an axis. From this Fig. 7b is also clearly visible that in the clamped state, the complete front side V of the blanks 1 and 2 is substantially completely accessible. As a result, unnecessary re-clamping is prevented and a complete working out of the dental elements E of two blanks 1 and 2 is feasible without intervening work by a dental technician would be necessary.
    8a and 8b show two blanks 1 and 2, wherein from the second blank 2 already a only schematically indicated dental element E is worked out. This dental element E is still connected via the webs 18 with the remaining area of the blank 2. In a later sequence, this dental element E is then removed from the second blank 2 by a dental technician or by special devices. Dental elements E can be, for example, crowns, bridges, or the like. Dental models are preferably produced from these blanks in order subsequently to perform teeth movement simulations. Also carrier models for dentures can be produced. The blanks 1 and 2 may, for example, zircon, metal, gypsum or plastic. It is again apparent from FIG. 8b that the special holding thicknesses D2 in the area of the auxiliary holding surfaces K2 together give rise to the standard fillet thickness D-1.
    The embodiments shown and described above are all suitable to be used in a specific embodiment of the applicant. Of course, however, the present invention can be used mutatis mutandis in each flattening device, which is explained in more detail by the following embodiments.
    FIGS. 9a and 9b show two blanks 1 and 2 which rest against one another via their respective rear sides R. Such simple, cylindrical blanks 1 and 2 can be clamped in an arrangement according to the invention and processed over both substantially completely accessible front sides V.
    The same applies to the blanks 1 and 2 according to FIGS. 10 a and 10 b, these blanks 1 and 2 each having a bevelled surface 20.
    11 a and 11 b show blanks 1 and 2, each with a continuous, peripheral gradation 21st
    Such a gradation 21 is also present in the blanks according to FIGS. 12a to 12c. One difference, however, lies in the fact that blanks 1 and 2 do not abut each other over their backs R over the entire surface, but contact each other directly only in a peripheral region (edge region).
    An alternative embodiment of a tensioning device 6 is shown in FIGS. 13a to 16c. Thus, all these representations have in common that the tensioning device 6 has an annular, one-piece clamping part 7, a plurality of clamping bolts 15 in the form of screws and the (inner) retaining ring 10 formed clamping surfaces 8.
    In order to clamp a single blank 1, according to FIG. 13c, the blank 1 is first placed on the clamping surface 8 via the step 21. Thereafter, the annular clamping part 7 is applied to the opposite side of the blank 1. Thereafter, the clamping bolts 15 are inserted into corresponding recesses in the clamping part 7. At the clamping bolt 15, an external thread is formed in each case, which engages in a corresponding manner formed in the retaining ring 10 internal thread. By screwing in this clamping bolt 15, the clamping member 7 presses against the blank 1, whereby the blank is clamped between clamping part 7 and clamping surface 8 and thus tightened or held.
    In a similar manner, two blanks 1 and 2 are clamped to a holding device 3 as shown in FIGS. 14a to 14c. Since in this clamping device 6 - in contrast to the clamping device 6 according to the first embodiment - the distance between clamping part 7 and clamping surface 8 in the clamping position K is variable, also an arrangement 5 is provided, in which substantially the entire front sides V of both blanks 1 and 2 are accessible to a processing device 9. This is especially possible because the blanks 1 and 2 are clamped or clamped only on their peripheral areas on the holding device 3 (this also applies to the first embodiment).
    In Fig. 15c shows that the retaining ring 10 additionally has an intermediate piece 22 which forms the clamping surface 8.
    In FIGS. 16a to 16c, two blanks 1 and 2 are clamped in such a holding device 3. For this purpose, a second, lower annular clamping part 7 is provided. In this case, a tensioning bolt 15 suitable internal thread may be formed in this lower clamping part 7. But it is also possible that the lower clamping part 7 via two "coming from below" and from there screwed to the retaining ring 10 clamping bolt 15 with the retaining ring 10 is connectable. In Fig. 16a is indicated by the dashed lines that more than two blanks 1 and 2 can be held in a holding device 3. For example, two separate, spaced and smaller (in this case approximately semicircular) blanks 1 can be clamped in "one plane". As a result, it is also possible that the second blank 2 can be processed by the processing device 9 at least partially via its rear side R. This is also possible if previously a sufficient range was already released by processing the first blank 1, which allows access to the back R of the second blank 2.
