Abstract
Description
本発明は、歯槽骨再生器具および歯槽骨再生装置に関する。さらに詳しくは、吸収された歯槽骨を健全な状態に再生させる治療器具に関する。 The present invention relates to an alveolar bone regeneration device and an alveolar bone regeneration device. More specifically, the present invention relates to a treatment instrument that regenerates absorbed alveolar bone into a healthy state.
人の歯の構造は、歯牙の根元が歯槽骨にとり囲まれ、歯槽骨によって支持され、顎骨の骨体部に結合されている。また、歯肉は歯槽骨の上部で歯牙をとり囲んでいる。人の歯が虫歯を病み、歯の神経に到達した細菌が根管を通って歯根周囲に到達すると、歯槽骨に病原因子を放出して、骨を溶かし吸収する。これを根尖病変という。 In the structure of human teeth, the root of the tooth is surrounded by the alveolar bone, supported by the alveolar bone, and connected to the bone part of the jawbone. The gingiva surrounds the tooth above the alveolar bone. When a person's teeth afflict dental caries and bacteria that have reached the tooth nerve reach the root circumference through the root canal, pathogenic factors are released into the alveolar bone, which dissolves and absorbs the bone. This is called apical lesion.
根尖病変により歯槽骨が吸収されていくと、歯は歯槽骨による支持力を失って動揺する。そして、歯槽骨が歯根の２／３まで、あるいは骨吸収が８ｍｍまで吸収されると、抜歯となるのが、現状の治療法である。
しかしながら、いったん抜歯すると、二度と歯を再生できないので、抜歯しないで治療できれば、その方が好ましい。
As the alveolar bone is absorbed by the apical lesion, the tooth loses its support and is shaken. Then, when the alveolar bone is absorbed to 2/3 of the root or bone resorption is absorbed to 8 mm, the current treatment method is to extract the tooth.
However, once the tooth is extracted, the tooth can never be regenerated, so it is preferable if it can be treated without extraction.
上記のような根尖病変を治療する従来技術として、特許文献１の技術がある。
この装置は、図７に示すように、病んだ歯の脈管神経束を治療して失活させるための装置（１０）であり、歯に在る開口に挿入する針の形状を成す第１電極（100）と、患者の身体に取付けるための第２電極（６４）及びこの第２電極（６４）に電気的接続する手握用ニュートラルハンドル（６０）との間に電気的に接続する電気回路からなる。この電気回路は、第１の電極（100）に接触する脈管神経束を破壊あるいは凝集させる高周波パルスを生成するＲＦパルサ部とを備え、第２電極（６４）を患者の唇に取付けて、歯の歯根尖に繋がる根管で案内される第１電極（100）の先端位置の計測をして、高周波パルスを前記ＲＦパルサ部から第１電極（100）に送出するものである。
As a conventional technique for treating apical lesions as described above, there is a technique disclosed in Patent Document 1.
As shown in FIG. 7, this device is a device (10) for treating and inactivating a vascular nerve bundle of a diseased tooth, and has a shape of a needle inserted into an opening in a tooth. Electrical connection between one electrode (100) and a second electrode (64) for attachment to the patient's body and a handgrip neutral handle (60) electrically connected to the second electrode (64) It consists of an electric circuit. The electrical circuit includes an RF pulser that generates a high-frequency pulse that destroys or aggregates the vascular nerve bundle in contact with the first electrode (100), and the second electrode (64) is attached to the patient's lips. The tip position of the first electrode (100) guided by the root canal connected to the root apex of the tooth is measured, and a high frequency pulse is sent from the RF pulser portion to the first electrode (100).
しかるに、上記従来技術では、歯髄を失活させるだけで、根尖病変を治癒することはできない。つまり、病んだ歯槽骨を再生治療することはできない。 However, with the above-described conventional technology, the apical lesion cannot be cured only by inactivating the pulp. In other words, the diseased alveolar bone cannot be regeneratively treated.
本発明は上記事情に鑑み、歯周組織を減菌し、骨芽細胞を活性化させることによって、歯槽骨の再生治療が可能な歯槽骨再生器具および歯槽骨再生装置を提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide an alveolar bone regeneration device and an alveolar bone regeneration device capable of regenerating treatment of alveolar bone by sterilizing periodontal tissue and activating osteoblasts.

第１発明によれば、能動針電極の直径が0.08〜0.47mmであるので、歯の根管に通すことができ、長さが25.0〜41.0mmであるので能動針電極の先端を歯根周囲に届かすことができる。そして、この能動針電極に通電すると直径が細いことから高い温度で発熱し、この高温および電気エネルギーで歯根周囲の細菌を死滅し、骨芽細胞を活性化させることができる。このように細菌を死滅させ、骨芽細胞を活性化させると 根尖病変が治癒機転を起こし、歯槽骨を再生させることができる。

According to the first invention, since the diameter of the active needle electrode is 0.08 to 0.47 mm, it can be passed through the tooth root canal, and since the length is 25.0 to 41.0 mm, the tip of the active needle electrode is placed around the tooth root. Can be delivered. When this active needle electrode is energized, it generates heat at a high temperature because of its small diameter, and bacteria around the root of the tooth can be killed and osteoblasts can be activated by this high temperature and electrical energy.

つぎに、本発明の実施形態を図面に基づき説明する。
図１に基づき本発明の一実施形態に係る歯槽骨再生器具Ａを説明する。
本発明の歯槽骨再生器具Ａは、病変し骨吸収が生じている歯槽骨を再生させるための治療器具である。図１において、１は能動針電極、２は被覆、３はハンドル部である。
能動針電極１は、通電により発熱する金属であって、腐食せず生体適合性の高いものが用いられる。そのような金属としては、ステンレススチールやニッケルチタンなどがある。
Next, an embodiment of the present invention will be described with reference to the drawings.
An alveolar bone regeneration device A according to an embodiment of the present invention will be described based on FIG.
The alveolar bone regeneration device A of the present invention is a therapeutic device for regenerating alveolar bone that is affected and bone resorption occurs. In FIG. 1, 1 is an active needle electrode, 2 is a coating | cover, 3 is a handle part.
The active needle electrode 1 is a metal that generates heat when energized and does not corrode and has high biocompatibility. Such metals include stainless steel and nickel titanium.
能動針電極１の長さは、25.0〜41.0mmの範囲が好ましく、31.0mm位が最も好ましい。この長さであると、歯の根管を通し、歯根周囲まで深く、能動針電極１の先端を届かすことができる。一方、25.0mmより短いと歯根周囲まで届かず歯の再生治療を行うことができない。逆に41.0mmより長いと、能動針電極の湾曲、破折などの問題を生じ、扱いにくくなる。 The length of the active needle electrode 1 is preferably in the range of 25.0 to 41.0 mm, and most preferably about 31.0 mm. With this length, it is possible to reach the tip of the active needle electrode 1 through the root canal of the tooth and deep into the periphery of the tooth root. On the other hand, if it is shorter than 25.0 mm, it does not reach around the root and cannot be regenerated. On the other hand, if the length is longer than 41.0 mm, problems such as bending or breakage of the active needle electrode occur, making it difficult to handle.
能動針電極１の直径は、0.08〜0.47mmが好ましく、0.10mm位が最も好ましい。この直径であると、歯の根管に無理なく通すことができ、治療に必要な発熱もさせやすい。0.08mmより外径が小さいと剛性が低くなり、折れやすく、扱いにくくなる。逆に0.47mmより大きいと、根管を通しにくかったり、充分な発熱量が得られない。 The diameter of the active needle electrode 1 is preferably 0.08 to 0.47 mm, and most preferably about 0.10 mm. If it is this diameter, it can be easily passed through the root canal of the tooth, and it is easy to generate heat necessary for treatment. If the outer diameter is smaller than 0.08mm, the rigidity will be low and it will be easy to break and difficult to handle. On the other hand, if it is larger than 0.47 mm, it is difficult to pass through the root canal, and sufficient calorific value cannot be obtained.
能動針電極１は、基部が太く先端が細いテーパ状にすると、先端ほどしなりやすくなって歯の根管に通しやすくなる。テーパは、1/100〜6/100が好ましく、とくに2/100位が適当である。 When the active needle electrode 1 has a taper shape with a thick base and a thin tip, the tip becomes easier to pass through the root of the tooth. The taper is preferably 1/100 to 6/100, particularly 2/100.
能動針電極１は、基部から先端まで断面が円形のままの針状であってもよいが、スパイラル状のものであってもよい。スパイラル状のものとしては、針状部材の外周に溝をスパイラル状に形成したものでもよく、さらに薄帯板をスパイラル状に巻き付けたものでもよい。
スパイラル状に形状した場合は、後述する被覆２が密着しやすく、被覆２が勝手に剥がれるのを防止できるメリットがある。
The active needle electrode 1 may have a needle shape with a circular cross section from the base to the tip, but may also have a spiral shape. The spiral member may be one in which a groove is formed in a spiral shape on the outer periphery of the needle-like member, and further a thin ribbon plate wound in a spiral shape.
When it is formed in a spiral shape, there is an advantage that the coating 2 described later can be in close contact and the coating 2 can be prevented from being peeled off.
被覆２は、前記能動針電極１の外面を被覆している。
その材料はめくり取れる材料であることが好ましく、たとえば、シリコン樹脂などが用いられ、被覆２の形成には、塗布や噴霧などが用いられる。
The coating 2 covers the outer surface of the active needle electrode 1.
The material is preferably a material that can be peeled off. For example, silicon resin or the like is used, and coating or spraying is used to form the coating 2.
この被覆２は、同時に根尖病変部内で焼成する場所を特定する役目を負っている。つまり、被覆２を1.0mm程度破り取り能動針電極１を露出させると、その部位のみ周囲の病変部に熱を伝達させることができる。通常は、能動針電極１の先端部の被覆２のみを、１mm位剥がして、先端から発熱させるようにし、能動針電極１自体の差し込み位置を深くしたり浅くしたりして、治療部位を変えていく。しかし、被覆２の破り取る部位を少しづづ変えて、能動針電極１を差し込んで通電しても病変部の違う部位に加熱治療を施すことができる。
このように加熱部位を狭い範囲に限定することで、一時に多くの電流を流すことなく、病変部を治療することができる。ちなみに、能動針電極１の先端を５mm以上露出させると、発熱は生じない。
This coating 2 has the role of specifying the place to be fired in the apical lesion at the same time. That is, when the covering 2 is broken by about 1.0 mm and the active needle electrode 1 is exposed, heat can be transmitted to the surrounding lesion only at that portion. Usually, only the coating 2 on the tip of the active needle electrode 1 is peeled off by about 1 mm to generate heat from the tip, and the treatment site is changed by deepening or shallowing the insertion position of the active needle electrode 1 itself. To go. However, even if the site where the coating 2 is torn off is changed little by little and the active needle electrode 1 is inserted and energized, it is possible to apply heat treatment to a different site of the lesion.
In this way, by limiting the heating site to a narrow range, it is possible to treat the lesioned part without flowing a large amount of current at a time. Incidentally, when the tip of the active needle electrode 1 is exposed 5 mm or more, no heat is generated.
ハンドル部３は能動針電極１の基部に形成されている。
通電時に手に熱を伝えない材料が用いられ、たとえばシリコンなどで、指先で持ちやすいように形成される。
The handle portion 3 is formed at the base portion of the active needle electrode 1.
A material that does not transmit heat to the hand when energized is used, such as silicon, so that it can be easily held by a fingertip.
つぎに、歯槽骨再生器具Ａに通電する通電制御器の使用法を説明する。
通電制御器は、直流または交流の電源（たとえば、家庭用100Ｖ電源）に接続して、歯槽骨再生器具Ａに通電する機器であって、公知の電気回路で構成されている。また、この通電制御器は、歯槽骨再生器具Ａに対し面積あるいは体積の大きい対極板とセットで用いられる。通電制御器に、歯槽骨再生器具Ａと対極板を接続して通電すると、断面積の小さい能動針電極１で発熱し、その熱が被覆２を破り取った小さな部分から病変部に伝えられる。
治療時には、能動針電極１の発熱温度は４０〜８０℃位にするのが好ましく、そのため、ステンレス製で上記寸法の能動針電極１であると、８０mAの電流を流せばよいが、これは家庭用100Ｖ電源で実現できる。
Below, the usage method of the electricity supply controller which supplies with electricity to the alveolar bone regeneration instrument A is demonstrated.
The energization controller is a device that is connected to a DC or AC power source (for example, a household 100 V power source) and energizes the alveolar bone regeneration device A, and includes a known electric circuit. This energization controller is used as a set with a counter electrode plate having a large area or volume with respect to the alveolar bone regeneration device A. When the alveolar bone regeneration device A and the counter electrode plate are connected to the energization controller and energized, the active needle electrode 1 having a small cross-sectional area generates heat, and the heat is transmitted to the lesioned portion from the small portion where the covering 2 is broken.
At the time of treatment, it is preferable that the active needle electrode 1 has an exothermic temperature of about 40 to 80 ° C. Therefore, if the active needle electrode 1 is made of stainless steel and has the above dimensions, an electric current of 80 mA may be applied. It can be realized with a 100V power supply.
通電波形については、連続波よりトーンバースト波を用いるのが好ましい。連続波の電流を流すと組織は切開されるが、断続波形であるトーンバースト波を流すと組織は熱凝固するからである。本明細書にいうトーンバースト波とは、半波方形型の波形であり、各波形が断続したものをいい、アーク放電が発生しやすく放電個所近辺に蓄積されるという特徴がある。
たとえば、ワット数は２０Ｗ±１０％で、１０パルス／0.1ｓの条件で１秒間通電すると（本明細書では、このような通電をワンショット通電という）、病変部の温度が40〜120℃位まで上昇するが、温度および電気エネルギーによって殺菌され、骨芽細胞が活性化される。それが骨再生につながると思われる。
For the energization waveform, it is preferable to use a tone burst wave rather than a continuous wave. This is because the tissue is incised when a continuous wave current is applied, but the tissue is thermally coagulated when a tone burst wave, which is an intermittent waveform, is applied. The tone burst wave referred to in this specification is a half-wave square waveform, which means that each waveform is intermittent, and is characterized in that arc discharge is likely to occur and is accumulated in the vicinity of the discharge location.
For example, when the wattage is 20 W ± 10% and energization is performed for 1 second under the condition of 10 pulses / 0.1 s (this energization is referred to as one-shot energization in this specification), the temperature of the lesion is about 40 to 120 ° C. However, it is sterilized by temperature and electric energy, and osteoblasts are activated. It seems to lead to bone regeneration.
本発明の歯槽骨再生器具Ａの使用法を、図２〜図４に基づき説明する。
図２において、Ｔは歯、Ｐは根管、Ｓは病変部である。図示のごとく、歯槽骨再生器具Ａの能動針電極１は歯Ｔの根管Ｐを通して病変部Ｓまで差し込まれている。つまり、能動針電極１の先端は病変部Ｓに届いている。本発明の能動針電極１は長く細いので、このように病変部Ｓまで届くのが、大きな特徴である。
図３に示すように、根管Ｐが曲っていても、能動針電極１が細く湾曲しやすいことから根管Ｐの奥深く差し込むことができ、図４に示すように病変部Ｓまでの根管Ｐの長さが長くても、能動針電極１自体が充分な長さを有しているので、能動針電極１の先端を病変部Ｓに届かせることができる。
図２に戻って説明すると、能動針電極１の先端部における１mm位の部分から被覆を剥がし取ると、その部分のみ発熱した熱を病変部Ｓに伝え、病変部Ｓを凝固させることができる。
The usage of the alveolar bone regeneration device A of the present invention will be described with reference to FIGS.
In FIG. 2, T is a tooth, P is a root canal, and S is a lesioned part. As shown in the figure, the active needle electrode 1 of the alveolar bone regeneration device A is inserted to the lesioned part S through the root canal P of the tooth T. That is, the tip of the active needle electrode 1 reaches the lesioned part S. Since the active needle electrode 1 of the present invention is long and thin, it is a major feature that it reaches the lesioned part S in this way.
As shown in FIG. 3, even if the root canal P is bent, the active needle electrode 1 is thin and easily bent, so that it can be inserted deeply into the root canal P, and the root canal up to the lesion S as shown in FIG. Even if the length of P is long, the active needle electrode 1 itself has a sufficient length, so that the tip of the active needle electrode 1 can reach the lesioned part S.
Returning to FIG. 2, when the coating is peeled off from the 1 mm portion of the tip of the active needle electrode 1, heat generated only in that portion is transmitted to the lesioned part S, and the lesioned part S can be coagulated.
上記のワンショット通電は、病変部（骨吸収部）に対して、２mm間隔で行う。つまり、病変部が深さ１８mmあるとすると、その部分に2.0mm間隔位を離して、次々とワンショット通電するので、６〜７ショットの通電が行われる。病変部が８mm位の深さであると、４回のワンショット通電を行い、病変部が２mm直径であると、１回のワンショット通電を行う。
この治療法は、１回〜数回の通電を行うと、それで終了し、通電治療後は、詰め物で根管を封鎖する。よって、何日も通院する必要はなく、１回の通院で済む。
The above-described one-shot energization is performed at intervals of 2 mm with respect to the lesioned part (bone resorption part). That is, if the lesioned part has a depth of 18 mm, the one-shot energization is performed one after another at intervals of 2.0 mm to the part, and thus energization of 6 to 7 shots is performed. When the lesioned part has a depth of about 8 mm, one-shot electrification is performed four times, and when the lesioned part has a diameter of 2 mm, one-shot electrification is performed.
This treatment method ends when energization is performed once to several times, and after energization treatment, the root canal is sealed with a filling. Therefore, it is not necessary to go to the hospital for days, and only one visit is required.
本発明の能動針電極１を用いた治療では、下記の２つの理由により、早期に骨再生が可能となる。
１）殺菌作用
根尖病変内の細菌を死滅させることにより、骨の吸収を抑制させる。
２）骨芽細胞の活性化
骨芽細胞ともうしまして、骨を作る細胞の増殖を促進する。
In the treatment using the active needle electrode 1 of the present invention, bone regeneration is possible at an early stage for the following two reasons.
1) Bactericidal action Bone resorption is suppressed by killing bacteria in apical lesions.
2) Activation of osteoblasts It promotes the growth of cells that make bone together with osteoblasts.
