Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dental retainer that is fitted to a tooth in order to hold a tooth corrected in dentistry in a corrected state, and more particularly to a dental retainer that does not cover the upper or lower jaw in the oral cavity.
[0002]
[Prior art]
A conventional dental retainer is composed of a labial wire that contacts the outer surface of a tooth and a synthetic resin portion having irregularities that conform to the inner surface of the tooth, between the wire and the irregularities of the synthetic resin portion. The dental retainer is fitted to the teeth by inserting the teeth into the gaps of the teeth, but in this case, the synthetic resin part located inside the teeth has an appropriate flexibility. It is necessary to have. Therefore, the conventional dental retainer provides a fixing force to the teeth (“fixing force” means a force to fix the teeth in a corrected state) by the synthetic resin portion having such flexibility. Therefore, the synthetic resin portion is inevitably increased in size, and is formed thick and wide. In particular, the synthetic resin portion of the upper tooth retainer covers almost the entire upper jaw (hard palate) in the oral cavity. Since the conventional dental retainer has such a large synthetic resin portion, the following problems have occurred.
(1) There is a sense of incongruity and the wearing feeling is bad.
(2) Sound disturbance occurs.
(3) It is difficult to eat during meals, and the taste of food and drink is impaired.
(4) Since the synthetic resin part has low heat conductivity, it cannot sense the temperature of food or drink.
(5) The synthetic resin part is unpleasant because it easily smells and easily becomes dirty.
(6) The synthetic resin part is easily broken when it is large.
[0003]
Since the dental retainer needs to be used for an extremely long period of time, these problems are serious for the user of the dental retainer, and Japanese Patent Laid-Open No. 8-168500 proposes a solution to the above problem. ing.
[0004]
That is, in FIGS. 13 to 17, the reference numeral 21 a indicates a maxillary tooth retainer, and the reference numeral 21 b indicates a mandibular retainer. The upper jaw retainer 21a is a substantially U-shaped metal support in which both ends 25a, 25a of the wire portion 23a contacting the outer surfaces 5a, 5a ... of the upper teeth 3a, 3a ... are positioned inside the upper teeth 3a, 3a ... The synthetic resin portion 31a having concavities and convexities 29a, 29a... Adapted to the inner side surfaces 7a, 7a... Of the maxillary teeth 3a, 3a ... is fixed to the metal support portion 27a, and the wire portion 23a. Are inserted into the gaps 33a between the concave and convex portions 29a, 29a, ... of the synthetic resin part 31a. On the other hand, the retainer 21b for the lower jaw teeth is a substantially U-shaped metal in which both ends 25b, 25b of the wire portion 23b contacting the outer surfaces 5b, 5b ... of the lower jaw teeth 3b, 3b ... are located inside the lower jaw teeth 3b, 3b ... A synthetic resin portion 31b having concavities and convexities 29b, 29b... Adapted to the inner surface sides 7b, 7b... Of the lower jaw teeth 3b, 3b. The lower jaw teeth 3b, 3b... Are inserted into the gaps 33b between the recesses 23b and 29b of the synthetic resin portion 31b.
[0005]
For example, the wire portions 23a and 23b are formed of a cobalt chrome alloy. The metal support portions 27a and 27b are formed of, for example, a titanium alloy, a cobalt chrome alloy, PGA (platinum alloy), or the like. The synthetic resin portions 31a and 31b are formed of a material having moderate flexibility such as polycarbonate or acrylic resin.
[0006]
In the synthetic resin portion 31a of the upper jaw retainer 21a, metal first reinforcing members 35 and 35 having one end 35 'fixed to the metal support portion 27a are embedded.
[0007]
The synthetic resin portion 31b of the lower jaw retainer 21b is penetrated by metal second reinforcing members 37, 37 having one end 37 'fixed to the metal support portion 27b. The end 37 ″ protrudes from the synthetic resin portion 31b.
[0008]
The synthetic resin portion 31a of the upper jaw retainer 21a is penetrated by metal third reinforcing members 39, 39 having one end 39 'fixed to the metal support portion 27a, and the metal third reinforcing members 39, 39 are combined. The other end 39 ″ protruding from the resin portion 31a is fixed to the wire portion 23a.
[0009]
Therefore, in this dental retainer, both the synthetic resin portion and the substantially U-shaped metal support portion can be made extremely thin and narrow. Therefore, even when it is attached to the maxillary or mandibular teeth, the maxilla or mandible in the oral cavity is not covered by the dental retainer. Therefore, the following effects are exhibited.
(1) There is no sense of incongruity and a feeling of wearing is good.
(2) No pronunciation problems occur.
(3) It is easy to eat when eating, and the taste of food and drink is not impaired.
(4) Since the synthetic resin portion having low heat conductivity is extremely thin and narrow, the temperature of food and drink can be sensitively sensed.
(5) Since the synthetic resin part which is easy to get a smell and is easy to get dirty is extremely thin and narrow, it is clean.
(6) Since the support portion is made of metal, it is strong.
(7) Since the synthetic resin portion is miniaturized, there is no possibility of cracking.
[0010]
The metal first reinforcing member 35 reinforces the synthetic resin portion. Therefore, the synthetic resin portion is durable.
[0011]
By locking the other end of the metal second reinforcing member 37 to the upper surface of the tooth, the dental retainer is more securely fixed to the tooth.
[0012]
With the metal third reinforcing member 39, the dental retainer can be more securely fixed to the teeth.
It is said.
[0013]
[Problems to be solved by the invention]
However, the above-mentioned retainers have the following difficulties.
(1) “It is possible to make both the synthetic resin portion and the substantially U-shaped metal support portion extremely thin and narrow in width.” The contents are titanium alloy, cobalt chrome alloy, PGA ( It is fixed (supported) in such a manner that an opposite surface provided with unevenness that matches the inner surface of the jaw teeth of the synthetic resin portion is connected to one end surface of a flat forged body such as a platinum alloy (FIGS. 14, 15, and 17). The reinforcement effect on the synthetic resin part (the same applies to the metal support part) can be obtained by simply bonding these two members together (it is understood that the synthetic resin part is backed up by the metal support part). It's not something you can expect.
[0014]
(2) Although frequently attached and detached, the mounting base that covers the palate is omitted and replaced with an arcuate wire loop body along the dentition, but with a simple plate-like arcuate loop frame, repeated vertically and horizontally However, there is a new problem that it is extremely difficult to withstand the torsion applied up and down, but there is no supplementary measure for such vulnerability.
[0015]
(3) Since the mutual reinforcing effect between the synthetic resin and the metal support portion is small, the degree of reduction of the synthetic resin portion cannot be increased, and therefore, the uncomfortable feeling at the time of mounting has not been sufficiently reduced.
[0016]
(4) Since the metal support directly touches the palate, tongue, food, etc., it is necessary to use a flat forged body such as titanium alloy, cobalt chrome alloy, PGA (platinum alloy), and the material cost is inevitably high. Become.
[0017]
(5) The wire portion is exposed over the entire region of the outer surface of the tooth, which is problematic from an aesthetic point of view, and consequently has a psychologically adverse effect on the user.
[0018]
Furthermore, the conventional dental retainer, including the above-mentioned JP-A-8-168500, has a mouth ring from the outer surface of the dentition, which is one of the main factors of the return after orthodontics. It does not have an effective function to effectively disperse and relieve pressure on muscles around the mouth, such as the buccal muscles, and the pressure is applied directly to the dentition of the anterior or posterior part of the teeth and induces retraction The big problem of doing so still remains.
[0019]
The present invention was devised to solve the problems in the prior art described above, and the object of the present invention is, in particular, orthodontic treatment by an effective mutual reinforcement method of the synthetic resin portion and the metal support portion. It has a function to effectively relieve pressure of the peroral muscles such as the muzzle muscles and cheek muscles from the outer surface of the dentition, which leads to a later reversion, and at the same time, it is excellent in wearing at low cost and reducing the amount of synthetic resin It is an object of the present invention to provide a dental retainer that is aesthetically pleasing by realizing the properties and minimizing the exposure of the metal support.
[0020]
[Means for Solving the Problems]
Of the present invention that achieves the above object, the means according to claim 1 is a dental retainer for maxilla,
It has clasps at both ends, a substantially U-shaped reinforcing wire along the inside of the dentition, and a bridging wire that connects between the clasps, and has irregularities that fit the inner surface of the tooth, bridging with the reinforcing wire Having a support part consisting of a resin floor held on the palate edge which takes a shape in which most of the outline is hollowed out leaving only 4-5 mm from the outer edge where the wire is embedded,
The both ends are connected to a reinforcing wire including the clasp portion, and a holding wire forming a loop frame surrounding a part of the reinforcing wire and a part of the dentition, and a resin pad in which a part of the holding wire is embedded. Having a buffer,
The reinforcing wire and the bridging wire or holding wire are brazed together;
The resin margin on the dentition side is to minimize the resin thickness, with the anterior teeth as the teeth and jaws and the molars as crown ridges,
With the support part mounted on the palate, the resin pad of the buffer part is configured to be held while forming a gap at a position facing the outer surface of the gums,
It is in.
[0021]
According to a second aspect of the present invention, there is provided a dental retainer for a lower jaw,
It has clasps at both ends, embedded with a substantially U-shaped reinforcing wire along the inside of the dentition, has irregularities that match the inner surface of the tooth, and is only 4-5 mm from the outer edge where the reinforcing wire is embedded Having a support part consisting of a resin floor held on the palate edge which takes the shape of the remaining hollow
The both ends are connected to a reinforcing wire including the clasp portion, and a holding wire forming a loop frame surrounding a part of the reinforcing wire and a part of the dentition, and a resin pad in which a part of the holding wire is embedded. Having a buffer,
The reinforcing wire and the holding wire are brazed to each other;
The resin margin on the dentition side is to minimize the resin thickness, with the anterior teeth as the teeth and jaws and the molars as crown ridges,
With the support part mounted on the palate, the resin pad of the buffer part is configured to be held while forming a gap at a position facing the outer surface of the gums,
It is in.
[0022]
According to the above configuration of claim 1 or claim 2, in the support portion, the auxiliary wire and the bridging wire are embedded in the resin, so that the mutual reinforcing effect between the resin floor and the wire is sufficiently exerted. In addition, it has a function of preventing the back to the inside of the dentition, and can further reliably back up a buffer portion described later.
[0023]
The presence of a resin bar (cross-clasp bridging wire embedded part) that crosses the palate's trailing edge makes it a three-dimensional structure, preventing the attached retainer from sinking and twisting, and preventing the patient from returning laterally, and mounting it in the appropriate position It can be repaired and corrected easily even with external force due to repeated attachment and detachment.
[0024]
In addition, since the contact area to the palate of the resin floor is reduced and thin, the function of the support part is sufficiently maintained, so the amount of resin used can be greatly reduced, and the user feels uncomfortable when wearing it. Can improve the problem.
[0025]
Further, since the wire is covered with the resin, it does not come into direct contact with the palate, tongue, food or the like, and it may be a low-cost standard product, which is advantageous in terms of cost.
[0026]
Furthermore, the tongue can be trained by touching the synthetic resin edge of the front tooth portion on the palate side with the tongue, and the use situation of the patient can be recognized by the impression of the resin floor portion generated by the backup of the resin bar. .
[0027]
Next, the buffer part was reinforced and backed up by embedding a part of the holding wire that forms a loop frame surrounding the part of the dentition together with the reinforcing wire, both ends being connected to the reinforcing wire including the clasp part. In the state, the ring pad and cheek muscles from the outer surface of the dentition, such as from the outer surface of the dentition, with the resin pad held while forming a gap at the position facing the outer surface of the gum, Disperses and relieves pressure around the peroral muscles, prevents direct force from being applied to some dentitions, and prevents deformation of the dentition.
[0028]
In other words, a certain gap is formed between the resin pad and the outer surface of the gums, and the pressure from the perioral muscles is not concentrated and applied directly to a part of the dentition, and the resin acts as a spring. It is transmitted from the pad to the holding wire, the reinforcing wire, and finally to the support portion, and is dispersed throughout the system by mutually complementary elastic deformation of the entire retainer.
[0029]
In addition, since this resin pad embeds most of the metallic holding wire located outside the dentition and is located in the gum part at the top of the dentition, there is little exposure of the metal part, and the resin pad It is difficult to see from the outside, and it is also aesthetically superior.
[0030]
The means described in claim 3 or claim 6 is a corrugated portion obtained by bending the holding wire portion embedded in the resin pad into a corrugated portion of the means of the invention of claim 1 or claim 2, respectively. is there.

According to the above-described configuration of claim 3 or claim 6, reinforcement to the resin pad by the holding wire and a backup effect are more exhibited, and the buffer portion more effectively relieves pressure from the peroral muscles such as the muzzle muscles and cheek muscles. To do.
[0032]
The means according to claim 4 is the means according to claim 1 or claim 3, and the means according to claim 7 is the means of the invention according to claim 2 or claim 6, wherein the resin pad is attached to the outer surface of the anterior tooth gum. In this configuration, the gap is formed while forming a gap at a position facing the.
[0033]
According to the above configuration of the fourth or seventh aspect, it is possible to effectively relieve pressure caused by excessive muzzle muscles in particular and prevent deformation of the dentition of the front tooth portion.
[0034]
The means according to claim 5 is the means according to claim 1 or claim 3, and the means according to claim 8 is the means of the invention according to claim 2 or claim 6, wherein the resin pad is attached to the outer surface of the molar gum. In this configuration, the gap is formed while forming a gap at a position facing the.
[0035]
According to the above configuration of the fifth or eighth aspect, in particular, it is possible to effectively relieve the pressure caused by excessive cheek muscles and to prevent deformation of the dentition of the molar portion.
[0036]

In this example, the last molar may be surrounded by a C clasp 104a.
[0040]
FIG. 5 shows the positional correlation between the front edge portion and the molar portion of the peripheral resin floor 101a and the reinforcing wire 102a of the support portion 100a in the first embodiment (the buffer portion 110a is omitted). By arranging the resin and the reinforcing wire 102a with respect to the dentition and mutual reinforcement, the support portion 100a itself has a function of suppressing the return to the inside of the dentition, and the buffer portion 110a can be reliably backed up. .
[0041]
FIG. 5 also shows the degree of reduction in the amount of synthetic resin used due to the mutual reinforcing effect between the resin and the reinforcing wire 102a as described above, and the same situation is shown in other examples described later.
[0042]
In FIG. 1, the buffer portion 110 a is provided with a resin pad 112 a in which a part of the holding wire 111 a is embedded in two portions that are symmetrical with respect to the outer side surface of the gum of the front tooth portion, and the holding wire 111 a reinforces both ends thereof. A loop frame is formed by brazing the wire 102a so as to surround a part of the reinforcing wire 102a and the left and right front teeth (medium incisors, side incisors, and six dog teeth total).
[0043]
More specifically, both ends of the holding wire 111a are brazed to the reinforcing wire 102a at positions opposite to each other in the vicinity of the gap between the canine and the first premolar, symmetrically on the inner side of the dentition. Crossing the dentition through, reaching the outside of the dentition, rising up from that position to the approximate center height of the gums, and bending it approximately 90 ° horizontally, forming a certain gap with the outer surface of the gums In this structure, a corrugated portion 113a that is bent in a wave shape is formed along the outer peripheral surface of the gum, and is disposed substantially symmetrically on the front tooth portion.

The resin pad 112a, which is symmetrically arranged in two places, the central incisor, the side incisor, and the canine, has a holding wire while embedding the corrugated portion 113a on the outer peripheral surface of the gum of the holding wire 111a. The position is maintained while forming a certain gap between the outer surface of the gums by the backup of 111a.
[0045]
Further, in the middle portion between the resin pads 112a, the holding wire 111a is exposed and a concave portion 114a is formed by bending it into a concave shape (in the second embodiment to be described later, it becomes a convex shape portion 114b). Hook your finger to make it possible to remove the entire retainer.
[0046]
With the configuration of the buffer part 110a as described above, a constant gap is formed between the resin pad 112a and the outer surface of the gums. This pressure is not directly applied to the dentition constituting the front tooth portion, but is applied from the resin pad 112a to the holding wire 111a, the reinforcing wire 102a, and finally the support portion 100a by a spring effect. It is transmitted and dispersed throughout the system by mutually complementary elastic deformation of the entire retainer.
[0047]
Further, most of the buffer portion 110a is at the height of the gums, and most of the holding wire 111a is embedded in the resin pad 112a. It is a thing.
[0048]
FIG. 2 shows a second embodiment of the present invention, which is an embodiment of a dental retainer for the lower jaw, and the support portion 100b surrounds the first molar with a C-clasp 104b in the same manner as in the first embodiment. In this embodiment, the basic shape is shown, and the buffer 110b is located at the front tooth portion.
[0049]
The peripheral resin floor 101b of the palate, which has irregularities that match the inner surface of the teeth, is continuous in a U-shape, and a reinforcing wire 102b extended from the C-clasp 104b is embedded therein.
[0050]
In this example, the last molar may be surrounded by the C clasp 104b.
[0051]
Similarly to the upper jaw of the first embodiment, in the buffer part 110b, the holding wire 111b is brazed to the reinforcing wire 102b at both ends, and a part of the reinforcing wire 102b and the left and right front teeth (medium incisors, A resin pad in which a loop frame is formed so as to surround side incisors and canine teeth, and the corrugated portion 113b of the holding wire 111b is embedded at two positions on the lateral side of the anterior surface of the gum, a symmetrical position. 112b is arranged.
[0052]
FIG. 3 shows a third embodiment of the present invention, which is an embodiment of an upper jaw dental retainer, and the structure of the support portion 100a is the same as that of the first embodiment.
[0053]
The buffer portion 110a is provided with resin pads 112a in which the corrugated shape 113a of the holding wire 111a is embedded at two positions on the lateral side of the gingival outer surface of the molar portion, and the holding wire 111a is connected to the canine tooth at one end. A portion of the reinforcing wire 102a is brazed to the reinforcing wire 102a through a gap between one premolar and the other end of the C clasp 104a surrounding the first molar at a portion located on the outer surface of the first molar. A loop frame is formed so as to surround the molar part (first premolar, second premolar, first premolar).
[0054]
In addition, the resin pad 112a is held by the holding wire 111a across the first premolars, the second premolars, and the first molars while facing the outer surface of the gums and forming a certain gap while maintaining the position. Yes.
[0055]
Due to the configuration of the buffer portion 110a as described above, a certain gap is formed between the resin pad 112a and the outer side surface of the gums. The pressure is transmitted directly from the resin pad 112a to the holding wire 111a, the reinforcing wire 102a, and finally to the support portion 100a by a spring effect without being concentrated and loaded on the dentition constituting the molar portion. The entire retainer is dispersed elastically by mutually complementary elastic deformation, and deformation of the dentition of the molar portion can be prevented.
[0056]
