Dental placement device

This invention relates to an improved apparatus for dental splint placement and Brackets on the teeth of patients, applicable not only to humans but also to animals.

Various types of newly deployed dental splinters and materials have become popular for stabilizing loose teeth. Some of these Materials are fabrics, braids, nets made of metal and plastic, perforated metal, metal rods, wires and similar. British published application 2110 093A describes some of these materials for Splints and their method of use, reference being made here to the content of this application.

Dental practitioners encountered problems in adapting these splinting materials to the tooth structure, to place, to handle with it and to fix it. An even bigger problem arises when the Teeth are crowded together making it difficult, if not impossible, to use the material and to be placed effectively, and to which an inordinate amount of time is spent in such a situation must, the patient has additional inconvenience and hindrances for the dentist and his Assistants occur.

A known placing device has already been described. It is made of plastic material and has Tongues in which a slot is cut so that

the material can be introduced into the slot after the plastic has been attached to the teeth. This device is extremely complex to manufacture, and requires careful slitting of the thin plastic material, which in turn is costly. In addition, these known devices require careful attention Insertion into the slot of a strip of metal mesh or mesh, whereby this is pushed through often catches and bends the very fine wire mesh, preventing the metal from passing through the slot can be pressed. This usually has an irreparable

as a result of damage to the metal strip, and due to a great loss of time for the dentist and the patient.

Another disadvantage of the known device is that once the metal strip has passed through the plastic holder is placed through it, it must be attached to the segment of the tooth to be splinted. To do this To accomplish this, the plastic tongues must run along the Slide the metal strip. This often causes the wires in the metal mesh to snag, causing the wires to bend will. Once the plastic retainer is properly in place and resin-bonded to the teeth, they must It is necessary to leave plastic tabs in it will. This is a significant disadvantage. It is impossible to move the tongues without compromising the embedded Remove metal and resin.

In another dental procedure, which is called an acid etch bridge or resin-bonded holder is known, the dentist uses the replacement tooth in a holder Brackets are placed where the patient's tooth is missing and the dentist then holds the support brackets against the adjacent teeth while the brackets are glued to them. One problem here is the Difficulty holding the small replacement tooth by hand or by means of instruments, with a simultaneous

Even pressure must be exerted on the retaining clips to press against the tooth structure. There is always the worry of inadvertent dropping of the holder and aspiration of the same by the patient.

It is therefore the object of the present invention to provide a new device for the simple placement of splint material to stabilize loose teeth.

Another object of the invention is to provide improved devices for facilitating placement of the and Connects to the splint material, bridges, holders and similar prosthetic devices create.

According to one aspect of the invention, monofilament strips are used or their equivalents are used as a device for placing. The strips are made by the practitioner inserted into the interproximal spaces of the tooth segment to be determined and lie on the gingival area on. The splint is now on the lingual and bukkai segments placed. The monofilaments are then brought over the splint and interproximally in the upper one Placed spaces, the ends are taken together

and can be pulled or tightened like a drawstring to tighten the rail and hold it against the To bring lingual and buccal segments into contact or to press them and thus the splint temporarily against the To hold teeth and to allow the splint into the interproximal section for additional reinforcement the bond strength is brought when the binding material described in the said British application is applied.

Another advantage of this aspect of the invention is that the splint is made easier by the interproximal placement of the Monofilaments is automatically adapted to the tooth position and texture. Even if the adhesive then hardens, Covered or impregnated by the resin with a rail, the special monofilaments stick together not, and can therefore easily be pulled out after letting go of one end of the threads lying in loops will.

According to another aspect of the invention is a Placement device provided, comprising a plurality of the monofilaments, which at least at one end by a common stripes are grouped together. With this arrangement after all the free ends of the monof! Laments If inserted interproximally and the splint is in place, the joint strip can pass through as a unit Pulling the number of threads together to press the splint against the teeth can be manipulated.

According to a further aspect of the invention, especially if a rear tooth is missing, the monofilaments can can be used by connecting parts of the splint to the existing teeth in order to attach them anchor these before applying the adhesive, and they can also be used interproximally to Splinting material on the facial and lingual surfaces of the

to bind together teeth to be stabilized. This procedure enlarges and enhances the covered tooth surface thus the holding force of the splint against the teeth, the application of the adhesive is much easier, and increases the bond strength after curing.

According to another aspect of the invention which is not can only be used for splinting, but also for bridges or holders, the monofilament placement

medium by pinning or threading onto or into the loop

tion, bridge or bracket attached to these so that the placement means can be used To give support to the latter and to hold it in position, in addition to pushing or pulling the same against the teeth of the Patients after correct positioning during the bonding process. This further facilitates dental treatment, and reduces the likelihood of the Falling of the prosthetic or restraining device.

According to another aspect of the invention, the splinting material is glued over the incisal surfaces or Beißflächen of a tooth or teeth, and if <ms necessary or desired, then directed to improve the shape of the Beißflächen. This offers the advantage of a relatively inexpensive procedure for reinforcing weakened incisal tooth edges, in particular for brittle front teeth, without noticeably endangering the patient's appearance.

The invention will now be described below in connection with some exemplary embodiments and with reference to the attached Drawings described. In the drawings shows -

The invention is for use with many types of Railing material suitable, which can be in the form of strips or bars with and without perforation. Of the The strip and the thin rod should have sufficient flexibility so that when the placement device is used the strip or rod flexes or can give way and firmly against the tooth surfaces and into the interproximal spaces can be drawn. Here are thin flexible, perforated strips of metal or Plastic preferred, as described in the aforementioned British application.

The adhesive used in the execution of the invention <* ►- 20 fabrics can be selected from the adhesives currently available to the dentist for many uses in dental restoration. These are typical resin composites, such as those supplied by the dental trade in the form of pastes or creams, or in the form of powder, which when mixed with liquid resin, liquids, pastes or creams result in the dated Dentists can be spread over the splint and usually self-cure by polymerization. The aforementioned application lists a number of examples of curable resins and composites that are suitable for use are useful in the present invention.

Although the monofilament is made of thin, pliable Wire, the preferred monofilament is made from a synthetic resin such as NYLON. As non-lost and non-meshed, this avoids the problem of a strand or a stitch becoming detached during insertion caught or chipped in the interproximal spaces. Another advantage of nylon thread is that it doesn't stick adheres to the cured adhesive and can therefore be removed again after use. Metal threads or However, threads of other compositions can also be used if so desired. When the material If the thread connects to the adhesive, it can be done after cutting off the non-adhering parts be left in it. Alternatively, a layer to prevent sticking, e.g. Vas3.ine, can be applied to the threads to prevent sticking.

With reference to the drawings, FIG. 1 shows schematically a lingual view of tooth segments which are to be splinted, comprising four teeth, here the two end teeth 10, 11 fixed, and the two central ones Teeth 12,13 are loose, and by applying the splint to be stabilized or fixed. As can be seen from FIG. 1, the three monofilaments 15 inserted into the interproximal spaces 14 and rest on the lingual tissue. Next is how out FIG. 2 shows a flexible braid or fabric 17 for splinting on the lingual surfaces via the tooth segments , placed. Each individual thread is now again inserted interproximally, as shown under 15 ', whereby 0 a loop is formed over the braid or fabric 17. The dentist or the assistant now collects the Free ends 16 protruding from the facial surfaces of the threads, and pulls them taut. This briefly presses the braid or fabric 17 for the splint against the tooth surfaces and pulls it into the interproximal Rooms 14, as can be seen from FIG.

While the threads are still held taut, next, mixed adhesive (not shown) is spread over the mesh or fabric surface in such a way that to fill in the gaps in the braid and thin layer over the edges of the tissue and into the interproximal spaces 14 through the spaces in the tissue and to apply the fabric edges. This is in the said British application described and omitted for the sake of clarity in the present drawing. Thereafter, while the threads are still held taut / ·%, the curing of the composition is awaited. It usually takes 5 minutes to harden. After curing, if the threads 15 are not on the cured composition adhere, one end of each thread released and the other ends for pulling out of the threads 15 drawn from the interproximal spaces 14. The final structure is that through which Adhesive composition solidified braid or fabric, resin-bonded with and over the teeth and thus a splint anchored to the fixed teeth 10, 11 Stabilization of the loose teeth 12,13. This is shown in Figure 3, with the resin again being the better Overview was omitted because of. This ends the procedure, with the exception of any removal work that may become necessary on protruding parts of the rail or the cured adhesive composition.

As can be seen from the foregoing description, the method of the invention is very simple to carry out, requires little time and is less subject to frustration and disappointment with the known methods. Increased Bond strength can be achieved because the braid or tissue is in contact with more tooth surface, and are reinforced by the parts of the rail, which, as shown schematically under 18 in FIG. 3, extend into the extend into interproximal spaces 14 and are glued therein. In addition, the placement device is in this case the monofilaments that are temporary

hold the splint against the teeth during bonding, not expensive and readily available, and can be thrown away after use.

Figure 4 shows one form of the new placement device, the plurality of filaments on a common Strips to facilitate manipulation with the placement device during the splinting procedure are summarized. As shown, the device, generally designated 21, consists of six monofilaments 22, which are combined or connected at one end to a first common strip 23, the preferably, but not necessarily, of the same material as used for the monofilaments 22, and wherein the opposite ends of the monofilaments are gathered at a second, common strip 24 are. In the embodiment shown only as an example, the strips 23, 24 consist of thin plastic sheet material having spaced holes therein, each of these filaments 22, as shown, passed through a hole 25 and at the free ends to prevent sliding back through the holes with knots 26 is secured. Alternatively, the ends of the filaments can be glued or otherwise secured to the strips will. Although only one such strip 23, 24 can be used here, the use preference is given to such common strips at both ends. And, although it is also possible, all ends of the To guide and combine filaments on one side to a common connection, it is preferable that the monofilaments, which are generally 0.1 to 1 mm wide, where they are combined in a designated 27 To arrange a distance that corresponds approximately to the interproximal distance of e.g. 3 - 8 mm.

When used, the monofilaments are individually interproximal while the dentist inserted the filaments 22

by pulling on the end strips 23, 24, as can generally be seen from FIG. Then the splint is applied, then one of the common strips, for example 23, is used to loop the appropriate number of filaments 22 around and over the splint and back into the interproximal spaces, as can be seen from FIG . The two strips 23, 24 are then firmly tightened and held, and the procedure continues as previously described. In order to be able to remove the **** 10 filaments after gluing, a common strip is cut off and the filaments are then pulled out by means of the other strip.

Individual monofilaments can be beneficial to another Manner can be used according to another aspect of the invention. Is a special situation sometimes given when a back tooth is missing. In the absence of lateral support for the adjacent teeth, after some Time the stability of these teeth is lost. A suitable mode of treatment here is through an over the Gap-reaching splinting given to stabilize the adjacent teeth, this as a permanent solution, or, as is more common, as a temporary makeshift until a replacement tooth is ready for placement into the gap. For permanent splinting, horizontal grooves are often used here along the facial or lingual surfaces ground in to accommodate a stable rod, which after gluing the state permanently stabilized. However, it is not very useful as a temporary measure since once the stable bar railing is removed, the ground in Grooves remain as permanent tooth damage.

According to this aspect of the invention, a flexible splint material can be of the type already described above Art can be used for temporary splinting. The problem, however, is how the flexible splint is

sufficiently with the adjacent, posterior teeth without physical damage to the same and in one Can be anchored in a way that, when the permanent tooth is inserted, the removal of the splint permitted. A suitable method can be seen in FIG. 5, which shows a single, rear Shows tooth 30 separated by a gap 31 from a number of adjacent teeth 3 2,33,34. The monofilaments 35,36,37 are used here, as shown, and lie on the gingival tissue. as Next, an elongated, thin, flexible and designed as a band or strip rail piece 38 is included its central portion 39, as shown, around the distal of the distal tooth 30 of the segment to be splinted, and with the bukkai and lingual ends extending along the tooth surfaces, wrapped. Now will be the first Filament 35, encompassing the bukkai and lingual ligament areas, along the mesial surfaces of the separated part Tooth 30 tied 40 tightly, and the remaining filaments 3 6.37 over the two band areas at 41 also tied off, and then the free ends, as can be seen from FIG. 6, cut off. this locks the ligament into place on the teeth and in each of the interproximal spaces, and presses the ligament against the Tooth surfaces, as is the case with the embodiments described above. The free ends of the splint band can be inserted ending in an interproximal space. Then what is not shown is next is, the adhesive composition over the tape for impregnation 0 of the same and over the adjoining tooth surfaces, as already described, distributed and then left to harden, whereby the tape solidifies and with the adjoining Tooth is glued. This stabilizes the teeth as a temporary measure, sufficient until the missing one is replaced Tooth. A significant advantage in treatment is that the temporary splint can be simply abraded or can be removed in a similar manner, the

the original structure of the teeth is absolutely preserved.

In the embodiments described above, the monofilament placement device is used separately from the splint. Figures 7 to 10 show modifications, which have the monofilaments attached to the rail and thereby not only the pressing of the Effect splinting against the teeth during bonding, but also the function of supporting the splint during treatment in the patient's mouth or externally. This has the advantage of being lighter Handling of the splint, especially if it contains a layer of tacky binder, and thus also reduces the likelihood that the still loose splint or loose monofilaments will accidentally fall off, when working in the patient's mouth, and consequently can also be aspirated by the patient.

In the embodiment of Figure 7 there are a number of monofilaments 50 attached to the areas 51 to be treated on a net-like, supple splinting strip 52. By tacking here is meant the point gluing, which is done using a drop of glue between the filament and the filament to be stapled with it Areas of the splint takes place. The splint 52 can thus be easily handled by means of the loose filament ends 53. Figure 7 shows one or more loose ends held by the practitioner's hand 54. At a The preferred form of treatment for use on a teaching model would be the splinting of the model of the teeth first of the patient can be adjusted, e.g. to bring them to the required length and width, and to predefined Define and shape V-shaped notches in the interproximal surface area, as in the British application is described. Next the monofilaments are underneath

Use of e.g. a cyanoacrylate adhesive attached to the intended locations in the interproximal area of the model. Thereafter, the aligned splint 52 would be inserted into the patient's mouth by means of the attached filaments, and, after a layer of an adhesive, a liquid adhesive or a cream-like adhesive composition, applied to the teeth or to one side of the splint or both, it is over the splint to be splinted To bring tooth segments 56, as shown in Figure 8, the monofilaments in the interproximal area of the Teeth inserted, as already described in connection with Figures 1-3, and the filaments then used to pull the splint 52 against the tooth surfaces and interproximal areas and in that position hold until the adhesive has hardened. In addition, glue can be applied to ensure that the interstices of the mesh are filled and, if necessary, remove the excess adhesive or to distribute it evenly over the mesh and the adjacent tooth surfaces in order to achieve a smooth surface, which the patient is less likely to complain about. The network impregnated with the hardened adhesive then forms the desired stable splint.

Figure 9 shows a modification in which the monofilaments 50 can be attached approximately to the interproximal area by threading it through the mesh gaps, such as this is shown at 57. Figure 10 shows a further modification in which the splint is a smooth, perforated strip made of thin plastic or metal, 0 and the monofilaments are threaded through the perforation here, as shown under 59. After the splinting procedure is finished, the excess Filament material by pulling it out (if it doesn't stick) or by removing the loose ends (if these glue) away. The filament ends can be loose, as shown, or through at one or both ends

Figures 11 and 12 applied an inventive feature in the case of a bridge or bracket of the "Maryland Bridge" type. The latter consists of a recording with bearing arms and with outwardly extending rotors-like ones Web 60 in which the replacement tooth 61 is used. In the procedure the bridge is lowered so that the replacement tooth fills the gap 62 of the missing tooth, and while the assembly is so held, the Web 60 attached to the adjacent teeth 63 by adhesive bonding. According to the invention, the monofilaments 64 pinned to the webs 60, and then used the monofilaments to place the bridge in the correct position, as well as pulling the webs 60 against the adjacent tooth surface 63 until the adhesive has hardened. In the modification of Figure 12, the webs 65 are perforated and the monofilaments 64 are used for fastening purposes threaded through the perforations.

Figure 13 shows another feature of the invention. In the embodiment of the splint described herein and in the British application, the flexible splint strip is preferably arranged and glued along the internal dental arch. The glued strip - thin and with a smooth outer surface - is less visible in this position and causes less discomfort for the patient. However, for the back teeth, where the splint would be less visible, this splint can be placed along the external dental arch and glued. In this embodiment, the flexible metal mesh-type splinting strip is glued directly onto the bite surfaces or incisal edges of one or more teeth by means of a liquid adhesive or a cream-like adhesive composition. This is particularly advantageous for the restorativ-perio-splinting weakened od he spr barren front teeth.

Ό O

This brittleness is critical for the incisal edge area of the tooth, which is the thinnest and weakest, and therefore this edge area is much more likely to break when biting. It was a difficult problem here, one to find a cost-effective solution. The inventive solution, which is also extremely inexpensive, sees the use the flexible or supple elongated railing • in the form of a net made of metal, which then becomes a kind of angled L-shape for one edge, or generally in a U-shape for both edges, and then with the Glue is applied directly over the bite surface of the tooth or over a number of several adjacent teeth. This is illustrated in FIG. 13, which shows the curved, shaped strip 71 over both bite edges of the tooth 73 glued shows. The impregnated, glued metal net solidifies and strengthens the biting edge 72, and reduces it the likelihood of breaking the edge. Following the gluing, the excess power supply units cut off and the net filled with the adhesive composition can now be sanded in the stable state or other means may be shaped to improve the cutting and biting efficiency of the tooth .. It may be found here as necessary to grind off the other tooth interacting with this in order to get one to achieve a perfect bite. This technique, inexpensive as it is, protects the tooth above all, and under certain circumstances

- save this one. Such inexpensive restoration procedures, like this and the others previously described, mean that proper dental care Care also for patients with lower incomes who could not afford the expensive conventional restorations, is available.

An improved placement device has been described herein, the single monofilament or multiple monofilaments used in summary.
