    The invention relates to a dental seat according to the preamble of claim 1. In particular, the invention relates to a module location suitable for the replacement of canines, canines and cheek teeth. Traditionally, teeth are patched by machining the tooth with a hand-held machining device with a rotating blade, a sand or soda blast nozzle, or a laser beam. The processing device makes a cavity in the dental crown, i.e. a pit that remains in the tooth after the caries, i.e. the softened hard tissue caused by the bacteria, has been removed. The cavity or crown grinding thus made is delimited by a mold and filled with the spot material once or in stages several times. The spot material is either cured by a chemical reaction or cured by intense ultraviolet light, or UV light. Disadvantages of such a spot can be uneven curing of the patch material or small air bubbles remaining in the material, varying breaking and compressive strength, microcracks in the tooth caused by shrinkage as the patch material cures, and joint leaks. Partially uncured material may also remain in place, which over time may cause an allergy to the person whose tooth has been patched.
    —The machined tooth and its counterparts can also be reproduced and a dental technician will place a spot or crown on the tooth. In this case, the patient has at least two visits to the clinic and the processed tooth must be protected in a temporary location, which requires a lot of work to do. The scanned tooth can also be imaged in the mouth from several different directions and made into a three-dimensional model of the tooth with a computer. After that, the milling robot works on a large blank or crown of a suitable size and color. On the latest devices, the place or crown is made with a 3D printer. In these methods = time is spent waiting for the final site to be completed and the equipment required is = complex and expensive.
    O 30 U.S. Pat. No. 5,098,800 A and U.S. Pat. The outer surface of the finished tooth site thus made and / or the volume of the site S generally contains a larger proportion of the site material than the prefabricated appendages 2 at opposite edges of the site. It is also known from the publications that the appendix placed in the cavity N 35 has an outwardly directed adhesion point on the surface corresponding to its chewing surface. It can be connected to a separate spring or tensioning device, which allows the edge of the appendage to be pressed firmly against the contact surface of the adjacent tooth.
    The external spring or clamping device and the gripping point are removed from the finished place.
    US 2003170593 A1 discloses a series of prefabricated tooth replacement blanks of different shapes and sizes.
    The shapes of the spot blanks are approximately in accordance with the basic classification of commonly used cheek and interdental cavities.
    The aim is to manually make the cavity to be patched in accordance with the corresponding classification.
    At the same time, a blank roughly resembling the cavity in question is selected from this series, with sufficient material removed from the surfaces and finally the shaped blank fits into the cavity.
    Finally, the gap between it and the blank can be quite wide from some edge point.
    The series thus becomes quite extensive so that a suitable blank can be found to be edited for cavities of different sizes and shapes.
    In the presented solution, problems also arise due to the variation of the base shape and depth of the cavity made in the tooth due to the removal of carious tooth tissue.
    In this case, the shaped blank can be partially sunk too deep into the cavity without being in contact with the opponent on its chewing surface.
    At the same time, a step is formed at the joint of the blank and the tooth on the chewing surface.
    It is not obstructed by small protruding protrusions at the bottom of the blanks.
    If the cavity extends to the edge of the tooth towards the adjacent tooth, the corresponding edge of the blank is obtained by stepwise grinding to finally fit into the cavity.
    The contact between the adjacent tooth and the patched tooth blank is not always sufficiently tight by this method.
    Therefore, when chewing the food threads, it is possible to press the gums of the area past the contact surface and the patient has to clean his gums separately after eating.
    The object of the present invention is to provide a dental site which does not have the above-mentioned drawbacks.
    It is a further object of the invention to provide a new = modular location which is different in structure and function from the known = solutions and which provides an efficient and inexpensive solution to most dental repair problems.
    In particular, the invention relates to a module location suitable for the O 30 positioning of canines, interdental and cheek teeth, the contact areas of which to the adjacent teeth are always made tight by the structure of the module position. & S The invention is characterized by what is set forth in the characterizing part of claim 1 2.
    According to the invention, the dental site is a module site which is assembled from N 35 - two or more modules.
    The modules and sub-chandeliers can be prefabricated in advance, which ensures that the module seats are of uniform quality.
    The modules may be made of any oral or medically acceptable material or mixtures thereof already in use. The filler may consist of one or more different types of fillers and / or dental prosthetic materials or mixtures thereof, the properties of which, such as wear resistance, tensile strength and thermal expansion, are compatible with the teeth. The modules produced in this way can be cured at high temperatures and pressures, leaving no internal stresses or partially uncured ingredients, so they cannot cause allergies even after years. The material selection of the module site, the shape of the modules and the final uniform structure of the module site consisting of modules are also essential for the invention.
    The modules of the dental seat according to the invention can be designed to be as healthy and intact as possible and to be sized so that the healthy dental crown needs to be ground as little as possible. After cementation, i.e. the attachment to the cavity, the module assembly assembled from the parts does not stress the adjacent crown part, whereby the resulting dental seat according to the invention withstands the bite stress well. Modules of different sizes and / or shapes can be combined with each other and thus their combinations can fill different types of cavities. Therefore, each cavity shape and / or size does not need its own unique module slot.
    —The dental position according to the invention also differs from the known dental filling methods in that the final modular position assembled from the parts and still integrated fits well into the cavity made in the tooth, always making tight contact with the adjacent teeth. The internal, mechanical structure of the module slot ensures tight contact with adjacent teeth.
    In the structure according to the invention, the module location is without a spring or tensioning device to be connected to the support tube extending outwards from the chewing surface. Tight contact with adjacent = teeth at the same time prevents the module slot from sinking too deep into the N tooth to be patched. In connection with the description of the figures, embodiments of the structure of the O 30 module slot according to the invention are shown in more detail. According to a preferred embodiment, one module of the E module slot has a support tube and an AN wedge arm supported by a thread of the support tube. When the wedge arm, which rests on the threaded support tube of the module slot, is rotated, its sharp tip S moves the modules of the module slot apart. In this case, the tip of the wedge arm remains 2 as part of the bite surface of the final module location. In the structure according to the invention, the wedge arm ensures that the gaps between the modules are filled with a flowable cementitious agent, such as an adhesive and / or a binder.
    According to a preferred embodiment, the adhesive and / or the binder enters the slots while the wedge arm acts as the piston axis of the filling syringe.
    The structure ensures that even the smallest joints in the module space are filled with cementing agent from the inside.
    Thus, the solution according to the invention is more efficient than when using an external, detachable - filling syringe, which does not always provide a continuous and air-bubble-free spray pressure on the cementitious agent.
    A detailed explanation of the solution of this embodiment is given in connection with the figures.
    According to the invention, it is advantageous that the tightness of the contacts on the neighboring teeth of the module site can be tested by rotating the wedge arm before the cementing step of the module site.
    In the cementation step, the unitary module location assembled from the modules is supported by holding the support tube so that the module location is in the correct position in the cavity.
    Thus, the module location does not sink too deep with respect to the chewing surface, allowing it to form a stepping location in the seam.
    In this case, the chewing surface of the module slot also hits the opponent when biting.
    According to a preferred embodiment of the invention, the module location comprises a basic module in which the support tube and the wedge arm resting on it are arranged.
    The side module is connected to the base module so that the connector pin belonging to the side module protrudes into the connector hole formed in the base module, which forms a guide to the connector pin.
    In this case, the connector pin can move in the guide formed by the connector hole so that the distance of the side module from the basic module is adjustable.
    The support tube in the base module of the module slot, which extends outwards from the chewing surface, is perpendicular to the connector pins in the connector hole.
    According to the invention, the support tube is thus used for many different functions.
    First, it is used as a holding point when moving the module slot or grinding any part of it.
    In the case of cementation, it acts as the body of the feed cavity and as the counterpart of the threads 5 of the wedge arm.
    In addition, if necessary, the module location can be held by means of a support tube = in the cavity at a suitable depth and position until it has adhered to the tooth N in the final cementation.
    Thus, the easy-to-form O 30 step differences in height at the joints between the site and the tooth are prevented. j AN Economically, modular placement is quite advantageous for both the patient and the dentist, S because the dentist does not have to make any expensive equipment investment.
    A mere selection of modules for the 2 available module slots is sufficient.
    The patient, in turn, saves N 35 both time and cost, as a single visit to the dentist completes a place that is in close contact with the adjacent teeth.
    It is also advantageous that the industrial production of the modular seats is advantageous after the initial investment.
    According to a preferred embodiment of the invention, the tooth location is a module location formed of two or more modules to be placed in the cavity of the tooth to be patched, where the distance between the modules is adjustable.
    In this case, the size of the module slot is 5 - adjustable to fit the cavity formed in the tooth to be patched and to make a suitable tight contact with the adjacent teeth.
    According to a preferred embodiment, the module slot comprises a base module with a control device and at least one side module connected to the base module so that the distance of the side module from the base module is adjustable by a control device belonging to the base module.
    In this case, the module location is made suitable for the cavity formed in the tooth to be patched, and at the same time a suitably tight contact is made with the neighboring teeth.
    According to a preferred embodiment, the module slot comprises a central base module, the side modules on both sides of which are a leading edge module and a trailing edge module.
    The side modules are connected to the base module so that the distance of at least one side module from the base module is adjustable or the distances of both side modules from the base module are adjustable.
    In this case, by adjusting the distance of the leading edge module and / or the trailing edge module from the base module, the size of the module slot can be adjusted to fit the cavity formed in the tooth to be patched and to provide a suitable tight contact with the neighboring teeth.
    According to a preferred embodiment, the adjusting device of the base module, by means of which the distance of the side module from the base module is adjustable, comprises a wedge arm which can be pressed against the inclined surface connected to the side module so that the side module moves away from the base module.
    It can also be made so that the distances of the side modules on both sides of the basic module can be adjusted N simultaneously by means of a wedge arm belonging to the control device 5 of the basic module.
    O 30 E According to a preferred embodiment, the control device of the basic module comprises a support tube with a threaded part AN and a knob with a thread to which the wedge arm is connected.
    A knob with a thread S is placed in connection with the threaded part of the support tube so that the knob is 2 in the threaded part.
    The tip of the wedge arm connected to the knob is positioned against the inclined surface associated with the side module N35 so that when the knob is rotated, the side module can be moved away from the base module. wherein the size of the module slot is adjustable to fit the cavity formed in the tooth to be patched and to provide a suitable tight contact with neighboring teeth. According to a preferred embodiment, the support tube of the base module forms a supply cavity through which the cement cementing the modules can be sprayed between the modules of the module location. Cement can be sprayed through the base pipe support pipe between the modules of the module location after the size of the module location has been adjusted to suit with the control device included in the base module. Cement can also be sprayed through the support tube of the base module between the modules of the module location at the same time as the size of the module location is adjusted by pushing the modules away from each other with the control device belonging to the base module. A chemically and / or light-curing rigid cementitious agent can also be applied to the bottom and / or side walls of the tooth cavity. The control module of the basic module is removed from the tooth site after the cement injected between the modules of the module site has hardened and the tooth site has cemented into place. The invention will now be described by way of example with reference to the accompanying drawings, in which

    DESCRIPTION OF THE FIGURES The wedge piston is formed by a separate piston 8 threaded into the wedge arm 7. The parts of the module compartment are durable and factory-made as well as tooth-shaped and colored. Figs. Fig. 1 shows an oblique projection and an exploded view of a MOD-N type module location according to the invention, which is suitable for the tooth cavity shown in Fig. 8. In the embodiment of Figure 10, the module slot has three main parts, which are the basic module 1 in the middle of the module slot E, the mesial module 15 AN or the leading edge module extending to the sides of the crown and also the distal module 14 or S extending to the sides of the crown. These main parts also form the occlusal surface> i.e. the chewing surface of the module site. SN purup In Fig. 1 there is a support tube 2 in the middle of the base module 1, in the upper part of which a threaded part 3 is made. is connected to the mesial module 15 and the distal module 14. On the support tube there is a marking ring 6, by means of which the exact depth of the wedge arm 7 to be pressed into the cementing agent in the supply cavity inside the support tube 2 is known. The wedge-shaped end of the wedge arm 7 rests on inclined surfaces in connection with the connecting pins 16, by means of which the distance between the modules of the module location and the contacts of the module location with the adjacent teeth can be adjusted. At the same time, a separate piston 8 threaded into the wedge arm 7 presses a flowable cementing agent into the feed cavity 4.
    A threaded knob 9 can be connected to the threaded part 3 of the support tube 2, to which the wedge arm 7 is attached. By turning the knob 9 attached to the wedge arm 7, it is made to engage the threaded part 3 of the support tube until the lower edge of the knob hits the upper edge of the marking ring 6. At the same time, the direction of the colored line 10 on the surface of the knob, if necessary, is seen - indicating the rotated position of the knob. The knob 9 has holes 11 into which the pressure pins 13 of the piston presser 12, which are parallel to each other, can be fitted. The modules of the module location can be assembled with the angular connector pins 16 of the distal module 14 and the mesial module 15, which fit into the respective angular connector holes 5 of the base module 1, preventing the modules from rotating and detaching from each other during the fitting step. A part is bevelled away from the corners of the side edges of the connecting pins 16 so as to form the feed grooves 17, whereby the small gaps between the connecting pins and the connecting holes 5 form side feed channels for the fluid cementing agent. They start with small, oblique concave recesses in the 16 ends of the connecting pins, the shape of which corresponds to the tip of the wedge piston. The mesial module 15 shows the oval S contact area 18 hitting the adjacent tooth drawn in broken lines. Fig. 2 shows a module slot according to the invention, assembled from the modules and parts of the module slot shown in Fig. 10. The substantially E three-part module location shown in the oblique projection consists of a distal module 14, a mesial AN module 15 and a basic module 1 pressed together. The basic module 1 S has a marker ring 6 on top of the support tube 2 and the support tube has a knob 9 attached to the threaded part 2, the wedge arm remaining hidden inside the tube. N 35 Figure 3 shows the module location of Figure 2 assembled and seen from above.
    Figure 4 is a vertical sectional view of the module location of Figure 3 taken along line A-A.
    In the module position of Fig. 4, the wedge arm 7 is moved to the initial position by turning the knob 9.
    In this case, the mesial module 15 and the distal module 14 are still attached to each other.
    The tip of the wedge arm 7 inside the basic module 1 contacts the inclined surfaces of the ends of the connector pins 16 without moving the distal 14 and mesial 15 modules apart.
    On top of the support tube 2 there is a marking ring 6, into which the lower edge of the knob 9 then strikes.
    The piston 8 is in the hole 4 inside the support tube inside the knob 9, resting on the base 20 of the wedge arm. Fig. 5 shows a vertical section from the module position of Fig. 3 along the line B-B.
    Also in the module position shown in Fig. 5, the wedge arm 7 is in its initial position.
    A supply cavity 21 is formed around the wedge arm 7 in the hole 4 inside the support tube, from which the main supply channels 22 lead to the end of the connector pin 16 visible in the connector hole in the basic module 1.
    Between the feed grooves 17 of the connector pin and the corners of the connector hole, four small - side feed channels 23 are seen.
    The knob 9 of the module slot is rotated so that the wedge arm 7 has moved deeper into the support tube 2. In this case, the sharp tip of the wedge arm 7 is pressed between the ends of the connector pins 16 against the oblique surfaces of the connector pins 16.
    In this case, the wedge arm 7 penetrating between the ends of the connector pins 16 pushes the distal module 14 and the mesial module 15 away from each other, increasing the overall length of the module location while pressing the modules 14 and 15 into contact with neighboring teeth.
    At the same time, the marking ring 6 and the piston 8 are displaced towards the base module 1 by the lower edge of the knob 9 and the base of the wedge arm o 20. According to the invention, this adjustable feature increasing the overall length of the position module 5 always
    At the same time, tight contact prevents the module slot from sinking too deep into the N tooth to be patched.
    O 30 E Fig. 7 is a sectional view corresponding to Fig. 5, in which the wedge arm is moved to adjust the distance of the N modules.
    As in Fig. 6, the wedge arm 7 has moved deeper S into the connector hole 5, whereby the sharp tip of the wedge arm 7 at the same time pushes the modules 14 and 15 away from each other.
    The supply cavity 21 is also slightly lowered and thus its volume is reduced.
    N 35 - The sharp tip of the wedge arm 7 is in the connector hole deeper at the end of the connector pin 16.
    Fig. 8 is an oblique plan view of three teeth, in which the middle or patchable left lower tooth 24 is provided with a partially dashed MOD-type cavity 25, i.e. a pit remaining in the tooth after caries removal. Figure 8 shows the base 26 and the side wall 27 of the cavity.
    Figure 9 is a sectional side view of the assembly of the assembled three-piece module location into the cavity 25 of the tooth to be patched between adjacent teeth 28 and 29 prior to final cementation. In this case, it is possible to check the fit of the module space in the tooth cavity 25 and, if necessary, grind the module to a suitable size. The module location is shown in a vertical sectional pattern in the plane A-A of Fig. 3, and the crown portion of the tooth to be patched is also sectioned in a corresponding plane.
    In Fig. 9, the knob 9 is rotated so that the sharp tip of the wedge arm 7 is pressed between the connecting pins 16 against their inclined surfaces and at the same time moved the distal module 14 and the mesial module 15 away from each other, increasing the overall length of the module slot.
    At the same time, seam gaps 31 have formed between both the distal module 14 and the mesial module 15 of the basic module 1.
    The rotation of the knob 9 is continued until the contact areas of the modules 14 and 15 press sufficiently tightly against the contact points of the neighboring teeth 28 and 29. If necessary, the tightness can be tested with dental floss. At the same time, the marking ring 6 has been pushed by the lower edge o of the knob 9 along the support tube 2 towards the basic module 1. The direction of the colored marking line 5 of the knob 9 then indicates the exact rotational position of the knob. It is pressed into memory so that when patching = the same contact tightness is obtained. According to the invention, this property, which increases the total length N of the module slot, always guarantees the tight contacts of the pre-tested module slot O to neighboring teeth.
    j AN Finally, the module slot is detached from the neighboring teeth by turning the wedge arm 7 from the knob 9 off the S connector pins 16 until the module slot can be easily removed from the cavity 25. The gap between the marking ring 6 and the knob 9.
    Figure 10 is a vertical sectional view of the initial stage of cementation of the assembled three-part module site of Figure 9 outside the mouth. The knob 9 with the wedge shaft 7 and the piston 8 of the module location has been removed and a chemically and / or light-curing, well-flowing cementing agent 32 has been sprayed into the hole 4 inside the support tube 2 with a suitable filling syringe 40 so that it exudes from the joints of the modules 1, 14 and 15. Then, holding the knob 9, the wedge arm 7 with the piston 8 is pressed into the cementing agent in the hole of the support tube 2 and rotated in the threaded part so that the lower edge of the knob 9 does not hit the marking ring 6. In this case, a fluid cementing agent is present in the joint gaps, the connection hole, the supply channels and the supply cavity between all parts of the module location. FIG. The module slot is pressed into place by holding the support tube 2 and the knob 9. If necessary, a thin matrix strip 34 supported by wedges 35 can be placed in advance between the tooth to be patched and the neighboring teeth to prevent the formation of excess cementing agent on the edges of the cavity. Fig. 12 is a vertical sectional view of the final stage of cementation of the assembled three-piece module site of Fig. 10, with the three-piece module site in its final position cemented in the cavity 25 of the tooth 24 between. The push pins 13 of the piston presser 12 fitted in the holes S of the knob 9 are pressed as deep as possible. - The modules 14 and 15 resting on the neighboring teeth have now been brought into tight contact O 30 with the neighboring teeth 29 and 28 by turning the knob 9 in the threaded part 3 of the support tube 2 to the contact E at the top of the marking ring 6 until the direction of the colored marking line 10 of the knob 9 corresponds to the N fitting phase.
    S 2 In this case, when the wedge arm 7 moves the modules 14 and 15 away from each other, a flowable cementing agent 32 is absorbed between them along the side and main supply channels due to the pressure difference acting on the connection hole 5. It may be absorbed as along the keyway 7 as air flows above the piston 8 through the holes 11 in the knob. Finally, the pressure pins 13 of the piston presser 12 are fitted in the holes of the knob 9, by means of which the piston 8 is pressed into the bottom of the feed cavity 21. Thus, like a syringe, a well-flowing cementing agent is forced from the supply cavity along the main and side feed channels to the seam slots of the connector pins 16 and the connector holes 5. If, however, the flowable and / or rigid cementing agent in the joints of the module site or in one of the walls of the cavity does not extend to the outer surface of the tooth to be repaired, the cementing or filling agent can be sprayed into the defects immediately before final curing. The cementing or locating agents harden or harden and the support tube 2 with its wedge arm 7 is removed above the chewing surface by cutting. Thus, a part of the wedge arm 7 remains inside the position module - between the parts. Finally, remove all excess and check the bite. Fig. 13 is a vertical sectional view of the situation of the final cementation of the module location, where the pins 13 of the piston presser 12 have moved the bottom of the piston 8 5, because in this example the module position is already in contact with the adjacent teeth 28 and 29. The pins 13 of the piston presser 12 ensure that the piston 8 moves to the bottom of the supply cavity 4 and the cementing agent protrudes into the connection hole 5. module locations. These examples do not describe the wedge arm 7, the piston 8 and the knob 9 belonging to the control and filling device of the basic module N of the module slot N.
    S 2 Figs.
    Fig. 18 shows a sub-crown in which the modules are connected to each other by means of a connector pin 16 and one or more additional connector pins 37. The angle module 38 of the sub-crown of Fig. 18 can be moved on the connector pin 16 and the parallel auxiliary connector pin 37 in the terminal hole 5 of the base module and in the mating hole 39 of the auxiliary connector pin.
    In Figures 15 and 18, the module locations have the module on one side of the base module only. In this case, the terminal hole 5 drawn in broken lines is closed at one end by a detachable connector pin 19. It is needed to fill the second opening of the terminal hole 5 of the basic module 1 in a two-part module slot. connector pin 19 is not required. In addition to the basic module, these three-part module slots consist of a mesial module 15 and a distal module 14 in Figure 14. In Figure 16, the module slots consist of a mesial module 15 and a chewing surface module 41. In Figure 17, the modular slots consist of - and the back edge. This support prevents the module site from sinking too deep into the cavity with the cementitious agent placed at its bottom. This ensures the evenness of the chewing surface without differences in the height of the joint. Figures 19-23 show, obliquely from above, examples of teeth with different cavities formed in the crowns. The module slots shown in Figures 14 to 18 fit these cavities so that module slot 14 fits cavity 19, module slot 15 fits cavity 20, module slot 16 fits cavity 21, »module slot 17 fits cavity 22 and module slot 18 fits cavity 23. ga REFERENCE NUMBER LIST E 30 1 2 Support tube N 3 —Threaded section S 4 Hole inside support tube 2 5 —Connection hole N 35 6 Marking ring 7 - Wedge arm 8 Piston
