以下、本考案の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【００１６】 図１は本考案による歯科矯正用具の一実施例を示す斜視図、 図２は図１に示す歯科矯正用具の平面図、 図３は図１に示す歯科矯正用具の正面図、 図４は図３に示す歯科矯正用具のＣ−Ｃ線による断面図、 図５は図１に示す歯科矯正用具を患者の歯に装着した状態を示す側面図であ る。FIG. 1 is a perspective view showing an embodiment of the orthodontic appliance according to the present invention, FIG. 2 is a plan view of the orthodontic appliance shown in FIG. 1, and FIG. 3 is a front view of the orthodontic appliance shown in FIG. 4 is a sectional view of the orthodontic appliance shown in FIG. 3 taken along the line C-C, and FIG. 5 is a side view showing a state in which the orthodontic appliance shown in FIG. 1 is attached to the patient's teeth.
【００１７】 本考案による歯科矯正用具５は、図１に示すように、腰があってしなやかな シリコーンゴム等の軟質の合成樹脂からなる一体成形品であり、咬合板部分１、 板状スクリーン部分２及び帯状部分３から構成されている。As shown in FIG. 1, the orthodontic appliance 5 according to the present invention is an integrally molded product made of a soft synthetic resin such as silicone rubber which is elastic and supple, and includes an occlusal plate portion 1 and a plate-shaped screen portion. 2 and the strip portion 3.
【００１８】 即ち、咬合板部分１は、図２に示すように、患者の歯列の曲がり具合に応じ て湾曲した形状を有しており、上下顎の前歯の咬合圧でも殆ど変形することのな い硬さを有している。咬合板部分１の上下端部には、図２及び図４に示すように 、それぞれ咬合面１ａ、１ｂが形成されており、各咬合面１ａ、１ｂには、細か い格子線状の凹みからなる滑り止め凹凸処理が施されている。また、咬合板部分 １の外周面（唇側）には、図３に示すように、咬合板部分１の厚みＴ１よりも幅 広であって腰のある丸みを帯びた略瓢箪形の板状スクリーン部分２が接合されて いる。一方、咬合板部分１の内周面（舌側）には、咬合板部分１の厚みＴ１（例 えば、２．５〜３mm）よりも幅広の帯状部分３が接合されており、帯状部分３の 両端部にはそれぞれ、図２に実線及び想像線で示すように、自在に撓み得る翼部 ３ａ、３ｂが形成されている。なお、咬合板部分１の両側に位置する板状スクリ ーン部分２及び帯状部分３は、既に述べたように、咬合板部分１の厚みＴ１より も幅広となっているので、咬合板部分１の厚み方向（矢印Ａ、Ｂ方向）の両側に は、図４に示すように、２本の平行な溝６、７が板状スクリーン部分２と帯状部 分３とによって囲まれて互いに上下方向、即ち矢印Ａ、Ｂ方向に対向する形で形 成されている。更に、歯科矯正用具５には、図３及び図４に示すように、３個の 通気孔５ａ、５ｂ、５ｃが、板状スクリーン部分２、咬合板部分１及び帯状部分 ３を唇側から舌側へ貫通する形でそれぞれ穿設されている。That is, as shown in FIG. 2, the occlusal plate portion 1 has a curved shape according to the degree of bending of the patient's dentition, and is almost deformed even by the occlusal pressure of the anterior teeth of the upper and lower jaws. It has no hardness. As shown in FIGS. 2 and 4, occlusal surfaces 1a and 1b are formed at the upper and lower ends of the occlusal plate portion 1, respectively. It has been treated with a non-slip texture. In addition, as shown in FIG. 3, the outer peripheral surface (lips side) of the occlusal plate part 1 is wider than the thickness T1 of the occlusal plate part 1 and has a generally round gourd-shaped plate with a rounded waist. The screen portion 2 is joined. On the other hand, on the inner peripheral surface (lingual side) of the occlusal plate part 1, a band-shaped part 3 wider than the thickness T1 of the occlusal plate part 1 (for example, 2.5 to 3 mm) is joined. As shown by the solid line and the imaginary line in FIG. 2, wing portions 3a, 3b that can freely bend are formed at both ends of the blade. Since the plate-shaped screen portion 2 and the strip-shaped portion 3 located on both sides of the occlusal plate portion 1 are wider than the thickness T1 of the occlusal plate portion 1 as described above, the occlusal plate portion 1 As shown in FIG. 4, two parallel grooves 6 and 7 are surrounded by the plate-shaped screen portion 2 and the strip-shaped portion 3 on both sides in the thickness direction (directions of arrows A and B) in the vertical direction. That is, it is formed so as to face in the directions of arrows A and B. Further, as shown in FIGS. 3 and 4, the orthodontic appliance 5 has three ventilation holes 5a, 5b, 5c which are formed on the tongue of the plate-shaped screen portion 2, the occlusal plate portion 1 and the belt-shaped portion 3 from the labial side. The holes are formed so as to penetrate to the side.
【００１９】 なお、この歯科矯正用具５は、大中小の３つのサイズのものが準備されてお り、患者の歯型や顔面の大きさに応じて適当なサイズの歯科矯正用具５を選択す ることにより、殆どの患者に適用することが可能となる。As the orthodontic appliance 5, three sizes, large, medium and small, are prepared, and the orthodontic appliance 5 having an appropriate size is selected according to the tooth shape and the size of the face of the patient. As a result, it can be applied to most patients.
【００２０】 本考案による歯科矯正用具５は以上のような構成を有するので、該歯科矯正 用具５を用いて混合歯列上顎前突の矯正治療を行なう際には、図５に示すように 、歯科矯正用具５の板状スクリーン部分２を唇側に、帯状部分３を舌側にして、 患者の歯に装着する。すると、患者は上下顎の両前歯８、９で歯科矯正用具５の 咬合板部分１を咬合面１ａ、１ｂを介して咬み込むことになるが、上顎の前歯８ が溝６に係合し、下顎の前歯９が溝７に係合するので、下顎を前進させて（上顎 を後退させて）咬ませることになることから、上下顎の矯正位置を維持した形で 混合歯列上顎前突の矯正治療を適正に行なうことが出来る。Since the orthodontic appliance 5 according to the present invention has the above-described structure, when performing orthodontic treatment of a mixed dentition maxillary anterior protrusion using the orthodontic appliance 5, as shown in FIG. The orthodontic appliance 5 is attached to the patient's teeth with the plate-shaped screen portion 2 on the labial side and the strip-shaped portion 3 on the lingual side. Then, the patient bites the occlusal plate portion 1 of the orthodontic appliance 5 with both front teeth 8 and 9 of the upper and lower jaws through the occlusal surfaces 1a and 1b, but the front teeth 8 of the upper jaw engages with the groove 6, Since the anterior teeth 9 of the lower jaw are engaged with the groove 7, the lower jaw is advanced (the upper jaw is retracted) to be bitten. Therefore, it is necessary to maintain the corrective positions of the upper and lower jaws in the mixed tooth row. Corrective treatment can be performed appropriately.
【００２１】 この際、咬合板部分１の各咬合面１ａ、１ｂには滑り止め凹凸処理が施され ているので、上下顎の両前歯８、９間の横ズレを防止して上下顎の矯正位置を安 定に維持することが可能となる。また、板状スクリーン部分２は上下口唇を動か す際の抵抗となり、上下口唇の口輪筋の発育を促す。なお、板状スクリーン部分 ２及び帯状部分３はいずれも腰があってしなやかであり、更に板状スクリーン部 分２は丸みを帯びていることから、これら板状スクリーン部分２、帯状部分３に よって患者の口腔内が傷付けられるような虞はなく、口腔内の異物感や圧迫感も 低減される。At this time, since each occlusal surface 1a, 1b of the occlusal plate portion 1 is subjected to anti-slip concavo-convex treatment, lateral displacement between the front teeth 8 and 9 of the upper and lower jaws is prevented to correct the upper and lower jaws. It is possible to keep the position stable. Moreover, the plate-shaped screen portion 2 serves as resistance when moving the upper and lower lips, and promotes the growth of the orbicularis muscle of the upper and lower lips. The plate-shaped screen portion 2 and the strip-shaped portion 3 are both supple and flexible, and the plate-shaped screen portion 2 is rounded. There is no danger of the patient's oral cavity being damaged, and the feeling of foreign matter and pressure in the oral cavity is reduced.
【００２２】 また、上下顎の両前歯８、９で咬合板部分１を咬み込んだ際、帯状部分３の 翼部３ａ、３ｂが臼歯１０、１１の歯肉部分に接することから、歯科矯正用具５ が着用中に脱落することを防止し、歯科矯正用具５を口腔内に安定に保持するこ とが出来る。Further, when the occlusal plate portion 1 is bitten by the anterior teeth 8 and 9 of the upper and lower jaws, the wing portions 3 a and 3 b of the strip-shaped portion 3 come into contact with the gingival portions of the molars 10 and 11. It is possible to prevent the orthodontic appliance from falling off during wearing, and hold the orthodontic appliance 5 stably in the oral cavity.
【００２３】 更に、歯科矯正用具５には３個の通気孔５ａ、５ｂ、５ｃが設けられている ので、患者は歯科矯正用具５の着用時にこれら通気孔５ａ、５ｂ、５ｃを通じて 空気を吸引・吐出することが可能となることから、歯科矯正用具５の着用によっ て患者の呼吸動作に支障を来すようなことはない。Furthermore, since the orthodontic appliance 5 is provided with three vent holes 5a, 5b, 5c, the patient can inhale and inhale air through the vent holes 5a, 5b, 5c when wearing the orthodontic appliance 5. Since the liquid can be discharged, wearing the orthodontic appliance 5 does not interfere with the breathing motion of the patient.
【００２４】 なお、以上に示した本考案の実施例はいずれもシリコーンゴム成形品からな る歯科矯正用具５の一例を示したもので、腰の強さの異なる他の材料、例えば同 じシリコーンゴムでも出発原料や架橋剤、重合度等が異なるシリコーンゴム、或 いはポリエチレン等のプラスチックなどから構成する場合には、咬合板部分１、 板状スクリーン部分２及び帯状部分３の厚みを適正な値に調整すればよく、また 、咬合板部分１と板状スクリーン部分２及び帯状部分３とにそれぞれ重合度の異 なるシリコーンゴムを用いたり、或いは互いに異なる材料を使用したりすること も出来るなど、本考案による歯科矯正用具５は実用新案登録請求の範囲内で様々 な態様が考えられる。Each of the embodiments of the present invention described above shows an example of the orthodontic appliance 5 made of a silicone rubber molded product, and other materials having different waist strengths, such as the same silicone, are used. If the rubber is made of a starting material, a cross-linking agent, a silicone rubber having a different degree of polymerization, or a plastic such as polyethylene, the thicknesses of the occlusal plate part 1, the plate-shaped screen part 2 and the band-shaped part 3 should be set appropriately. It is only necessary to adjust the values, and it is also possible to use silicone rubbers with different degrees of polymerization for the occlusal plate part 1, the plate-shaped screen part 2 and the band-shaped part 3, or to use different materials.

Occlusal surfaces 1a and 1b are formed on the occlusal surface, and the occlusal plate portion 1 is provided on the labial side with a rounded plate-like screen portion 2 having a width wider than the thickness T1 of the occlusal plate portion 1 and having a waist. The occlusal plate portion 1 is provided with a strip-shaped portion 3 wider than the thickness T1 of the occlusal plate portion 1 on the lingual side, and the plate-shaped screen portion 2 and the strip-shaped portion 3 allow the occlusal plate portion 1 to have a thickness direction (for example, Since two parallel grooves 6 and 7 capable of engaging and engaging both front teeth 8 1 and 9 of the upper and lower jaws are formed on both sides (in the directions of arrows A and B in FIG. 4), the orthodontic appliance 5 is formed. When worn, the lower and upper incisors are pressed down and occlusal. Order will be front teeth 8 and 9 bite by bite the part 1 the molars 10 and 11 free, the effect of correcting such as coming out to perform Ting and out of the molars 10 and 11 also enough is exhibited. Furthermore, since it can be used in combination with other multi-bracket systems, it is ideal for orthodontic treatment of mixed dentition maxillary anterior protrusion during the observation period. Further, the plate-shaped screen portion 2 and the strip-shaped portion 3 form two parallel grooves 6 and 7 capable of engaging and engaging both front teeth 8 and 9 of the upper and lower jaws on both sides in the thickness direction of the occlusal plate portion 1. Therefore, wearing the orthodontic appliance 5 ensures the positioning and advancement of the tongue and jaw incisor and the growth of the lower jaw. In addition, the plate-shaped screen portion 2 can surely give the action of muscle training for the lips. In this way, multiple corrective effects are exerted, so conventionally, it took two years to wear it all day (24 hours), but it took about 12 hours a day to wear it, although the correction period for two years remains the same. It is possible to reduce the annoyance of the patient, that is, the side receiving the orthodontic treatment.
【００２６】 また、大中小の３種類のサイズのものを揃えることによって殆どの患者に適 用できる歯科矯正用具５が提供され、また、咬合板部分１、板状スクリーン部分 ２及び帯状部分３から構成された歯科矯正用具５であって簡単に着脱できること から、歯科矯正用具５を提供するまでプロセスが簡略化され、混合歯列上顎前突 患者が矯正に要する時間・費用が短縮・軽減されると共に、歯科医、即ち歯科矯 正治療を行なう側の労力が低減される。In addition, an orthodontic appliance 5 that can be applied to most patients is provided by arranging three kinds of sizes, large, medium and small, and the occlusal plate part 1, the plate-shaped screen part 2 and the band-shaped part 3 are provided. Since it is a configured orthodontic appliance 5 that can be easily attached and detached, the process is simplified until the orthodontic appliance 5 is provided, and the time and cost required for orthodontic patients with mixed dentition maxillary anterior protrusion are shortened and reduced. At the same time, the labor of the dentist, that is, the side performing the dental treatment is reduced.
【００２７】 また、上記帯状部分３に、上下顎の前歯８、９で上記咬合板部分１を咬み込 んだ際に臼歯１０、１１の歯肉部分に接する翼部３ａ、３ｂを形成して構成する と、上下顎の両前歯８、９で咬合板部分１を咬み込んだ際、帯状部分３の翼部３ ａ、３ｂが臼歯１０、１１の歯肉部分に接して保持されることから、歯科矯正用 具５が着用中に脱落する事態の発生を防止することが出来る。Further, the band-shaped portion 3 is formed by forming wing portions 3a and 3b which are in contact with the gingival portions of the molars 10 and 11 when the occlusal plate portion 1 is bitten by the front teeth 8 and 9 of the upper and lower jaws. Then, when the occlusal plate part 1 is bitten by the anterior teeth 8 and 9 of the upper and lower jaws, the wing parts 3a and 3b of the strip part 3 are held in contact with the gingival parts of the molars 10 and 11, It is possible to prevent the orthodontic device 5 from falling off during wearing.
【００２８】 また、上記咬合板部分１、板状スクリーン部分２及び帯状部分３を貫通する 通気孔５ａ、５ｂ、５ｃを設けて構成すると、通気孔５ａ、５ｂ、５ｃを通して 空気を吸引・吐出できるので、歯科矯正用具５の着用時の呼吸が楽になる。Further, when the vent holes 5a, 5b, 5c penetrating the occlusal plate part 1, the plate-shaped screen part 2 and the strip part 3 are provided, air can be sucked and discharged through the vent holes 5a, 5b, 5c. Therefore, breathing becomes easy when wearing the orthodontic appliance 5.
