Description
本考案は、人工歯と人工歯を保持する義歯床を備える義歯に関する。 The present invention relates to a denture having an artificial tooth and a denture base for holding the artificial tooth.
従来、義歯床を口腔内の歯槽堤に覆わせることで、義歯を口腔内に装着することが知られている（例えば、特許文献１参照）。 Conventionally, it is known that a denture is mounted in the oral cavity by covering the denture base with an alveolar ridge in the oral cavity (see, for example, Patent Document 1).
特許文献１に記載の義歯は、人工歯を支持する支持床部と、支持床部に連結され歯槽堤に沿うよう延設された頬側部と内側部とを有し、支持床部が硬質の樹脂により形成され、頬側部及び内側部が柔軟な樹脂により形成されている構成が開示されている。これにより、装着者の口腔表面に対する義歯床の密着性を改善する。 The denture described in Patent Document 1 has a support floor portion that supports artificial teeth, a cheek side portion that is connected to the support floor portion and extends along the alveolar ridge, and an inner portion, and the support floor portion is hard A configuration in which the cheek side and the inner side are formed of a flexible resin is disclosed. Thereby, the adhesiveness of the denture base with respect to a wearer's oral cavity surface is improved.
しかしながら、特許文献１に記載の義歯は、単に頬側部と内側部とを装着者の歯槽堤に密着させているだけであり、歯槽堤に対してぐらついてしまう、という問題がある。 However, the denture described in Patent Document 1 has a problem that the cheek side portion and the inner side portion are simply brought into close contact with the alveolar ridge of the wearer, and the wobble is loosened with respect to the alveolar ridge.
そこで、本考案は、義歯の装着状態において、口腔内の歯槽堤に対するぐらつきを抑えることができる義歯を提供することを目的とする。 Then, an object of this invention is to provide the denture which can suppress the wobble with respect to the alveolar ridge in an oral cavity in the mounting state of a denture.
前記目的を達成するために、本考案の義歯は、人工歯と、前記人工歯を保持する義歯床と、を備える義歯であって、前記義歯床は、口腔内の歯槽堤の上面を覆う上部と、前記歯槽堤の外側側面を覆う側部と、から構成され、前記側部の裏面に、前記外側側面に形成した穴部に挿入する挿入ピンを設けることを特徴とする。 In order to achieve the above object, the denture of the present invention is an artificial tooth including an artificial tooth and a denture base that holds the artificial tooth, and the denture base is an upper part that covers the upper surface of the alveolar ridge in the oral cavity. And a side portion that covers the outer side surface of the alveolar ridge, and an insertion pin that is inserted into a hole formed in the outer side surface is provided on the back surface of the side portion.
このように構成された本考案の義歯では、義歯の装着状態において、口腔内の歯槽堤に対するぐらつきを抑えることができる。 With the denture of the present invention configured as described above, wobbling with respect to the alveolar ridge in the oral cavity can be suppressed in the mounted state of the denture.
以下、本考案による義歯を実現する実施形態を、図面に示す実施例１に基づいて説明する。 Hereinafter, an embodiment for realizing a denture according to the present invention will be described based on Example 1 shown in the drawings.
［義歯の構成］
図１は、実施例１の義歯の構成を示す斜視図である。図２は、実施例１の義歯の構成を示す断面図である。以下、図１及び図２に基づいて、実施例１の義歯の構成を説明する。
[Configuration of denture]
FIG. 1 is a perspective view illustrating a configuration of a denture of Example 1. FIG. FIG. 2 is a cross-sectional view showing the configuration of the denture of Example 1. Hereinafter, based on FIG.1 and FIG.2, the structure of the denture of Example 1 is demonstrated.
義歯１は、図１及び図２に示すように、下顎用の義歯であり、人工歯２と、人工歯２が取り付けられた義歯床３と、２つの挿入ピン１０と、を備える。 As shown in FIGS. 1 and 2, the denture 1 is a denture for the lower jaw, and includes an artificial tooth 2, a denture base 3 to which the artificial tooth 2 is attached, and two insertion pins 10.
人工歯２は、例えばセラミックで形成され、義歯床３に取り付けられる。 The artificial tooth 2 is formed of ceramic, for example, and is attached to the denture base 3.
義歯床３は、例えば硬質の樹脂で形成され、略水平に延在する上部３ａと、上部３ａの外縁から下方に延在する側部３ｂと、で断面略Ｌ字状になっている。 The denture base 3 is formed of, for example, a hard resin and has a substantially L-shaped cross section with an upper part 3a extending substantially horizontally and a side part 3b extending downward from the outer edge of the upper part 3a.
上部３ａは、口腔内の歯槽堤２０の上面２０ａを覆い、側部３ｂは、歯槽堤２０の外側側面２０ｂを覆うように形成される。側部３ｂには、挿入ピン１０の一部が埋め込まれる。 The upper part 3 a covers the upper surface 20 a of the alveolar ridge 20 in the oral cavity, and the side part 3 b is formed so as to cover the outer side surface 20 b of the alveolar ridge 20. A part of the insertion pin 10 is embedded in the side portion 3b.
挿入ピン１０は、例えば金属製であり、挿入ピン本体１０ａと、挿入ピン基部１０ｂと、でＬ字状に形成される。挿入ピン１０は、断面円状で、直径略１ミリに形成される。挿入ピン１０は、犬歯に対応する位置に、それぞれ、設けられる。 The insertion pin 10 is made of metal, for example, and is formed in an L shape with an insertion pin main body 10a and an insertion pin base portion 10b. The insertion pin 10 has a circular cross section and is formed with a diameter of about 1 mm. The insertion pins 10 are provided at positions corresponding to the canines.
挿入ピン基部１０ｂが、側部３ｂに埋め込まれることで、挿入ピン１０は、義歯床３に取り付けられる。挿入ピン本体１０ａは、側部３ｂの裏面から、装着者から見て後方に、水平方向に延びるように形成される。２つの挿入ピン本体１０ａは、平行に配置され、義歯１を装着する際に、穴部２０ｃに容易に挿入できるようになっている。挿入ピン本体１０ａは、例えば１０ミリの長さＬを有する。 The insertion pin 10 is attached to the denture base 3 by the insertion pin base 10b being embedded in the side 3b. The insertion pin main body 10a is formed so as to extend in the horizontal direction from the back surface of the side portion 3b to the rear as viewed from the wearer. The two insertion pin main bodies 10a are arranged in parallel, and can be easily inserted into the hole 20c when the denture 1 is mounted. The insertion pin main body 10a has a length L of 10 mm, for example.
口腔内の歯槽堤２０の外側側面２０ｂには、挿入ピン本体１０ａより若干大きな直径の穴部２０ｃが、例えばレーザ加工機等により形成されている。穴部２０ｃには、挿入ピン本体１０ａが挿入可能となっている。穴部２０ｃは、歯槽堤２０の内側側面２０ｄまで貫通する貫通穴とすることができる。 A hole 20c having a slightly larger diameter than the insertion pin main body 10a is formed on the outer side surface 20b of the alveolar ridge 20 in the oral cavity, for example, by a laser processing machine or the like. The insertion pin main body 10a can be inserted into the hole 20c. The hole portion 20 c can be a through hole that penetrates to the inner side surface 20 d of the alveolar ridge 20.
［義歯の装着方法］
図３は、実施例１の義歯の装着方法を示す分解図である。以下、図３に基づいて、実施例１の義歯の装着方法を説明する。
[How to wear dentures]
FIG. 3 is an exploded view showing the denture mounting method of the first embodiment. Hereinafter, based on FIG. 3, the mounting method of the denture of Example 1 is demonstrated.
装着者は、義歯１を指でつかみ、口腔内へ挿入する。そして、装着者は、例えば鏡越しに、挿入ピン１０と歯槽堤２０の穴部２０ｃとを確認しながら、挿入ピン１０を穴部２０ｃに挿入する。そして、義歯床３を歯槽堤２０に密着させる。これにより、義歯１を装着する。 The wearer grasps the denture 1 with a finger and inserts it into the oral cavity. Then, the wearer inserts the insertion pin 10 into the hole 20c while confirming the insertion pin 10 and the hole 20c of the alveolar ridge 20 through a mirror, for example. Then, the denture base 3 is brought into close contact with the alveolar ridge 20. Thereby, the denture 1 is mounted.
義歯１の装着状態では、図２に示すように、義歯１の側面が唇３０の内面と当接する。 In the mounted state of the denture 1, the side surface of the denture 1 comes into contact with the inner surface of the lip 30 as shown in FIG.
［義歯の作用］
以下、実施例１の義歯１の作用について説明する。実施例１の義歯１は、人工歯２と、人工歯２を保持する義歯床３と、を備える義歯１であって、義歯床３は、口腔内の歯槽堤２０の上面２０ａを覆う上部３ａと、歯槽堤２０の外側側面２０ｂを覆う側部３ｂと、から構成され、側部３ｂの裏面に、外側側面２０ｂに形成した穴部２０ｃに挿入する挿入ピン１０を設ける（図２）。
[Function of denture]
Hereinafter, the operation of the denture 1 of Example 1 will be described. The denture 1 of Example 1 is a denture 1 including an artificial tooth 2 and a denture base 3 that holds the artificial tooth 2, and the denture base 3 is an upper portion 3 a that covers the upper surface 20 a of the alveolar ridge 20 in the oral cavity. And a side portion 3b covering the outer side surface 20b of the alveolar ridge 20, and an insertion pin 10 to be inserted into a hole portion 20c formed in the outer side surface 20b is provided on the back surface of the side portion 3b (FIG. 2).
これにより、装着者から見た左右方向において、義歯１を歯槽堤２０に対して位置規制をすることができる。また、義歯１は、図２に示すように、唇３０の内面によって支持されるため、装着者から見た前後方向のぐらつきを防ぐことができる。そのため、義歯１の装着状態において、口腔内の歯槽堤２０に対するぐらつきを抑えることができる。 Thereby, position control of the denture 1 with respect to the alveolar ridge 20 can be performed in the left-right direction seen from the wearer. Moreover, since the denture 1 is supported by the inner surface of the lip 30 as shown in FIG. 2, it can prevent the wobbling in the front-rear direction seen from the wearer. Therefore, the wobbling with respect to the alveolar ridge 20 in the oral cavity can be suppressed in the mounted state of the denture 1.
また、義歯１を装着する際に、鏡越しに、挿入ピン１０と穴部２０ｃを確認することができる。そのため、義歯１を容易に装着することができる。 Further, when the denture 1 is mounted, the insertion pin 10 and the hole 20c can be confirmed through the mirror. Therefore, the denture 1 can be easily mounted.
また、義歯１の装着状態では、挿入ピン１０が穴部２０ｃに挿入されるため、外部から挿入ピン１０が見えないようにすることができる。そのため、義歯１の装着状態において、見た目をスッキリさせることができる。 Moreover, in the mounting state of the denture 1, since the insertion pin 10 is inserted in the hole part 20c, the insertion pin 10 can be hidden from the outside. Therefore, the appearance can be refreshed when the denture 1 is mounted.
実施例１の義歯１では、穴部２０ｃは、貫通穴である（図２） In the denture 1 of Example 1, the hole 20c is a through hole (FIG. 2).
これにより、穴部２０ｃに異物が入った際に、穴部２０ｃに棒状の物（例えば、綿棒）を挿入して、異物を除去することができる。そのため、口腔内を清潔に保つことができる。 Thereby, when a foreign material enters the hole 20c, a rod-like object (for example, a cotton swab) can be inserted into the hole 20c to remove the foreign material. Therefore, the oral cavity can be kept clean.
以上、本考案の義歯を実施例１に基づき説明した。しかし、具体的な構成と動作については、この実施例に限られるものではなく、実用新案登録請求の範囲の各請求項に係る考案の要旨を逸脱しない限り、設計の変更や追加等は許容される。 The denture of the present invention has been described based on the first embodiment. However, the specific configuration and operation are not limited to this embodiment, and design changes and additions are allowed without departing from the spirit of the invention according to each claim of the utility model registration claim. The
実施例１では、義歯１を総義歯とする例を示した。しかし、義歯は、図４に示すように、部分義歯１０１であってもよい。この場合、挿入ピン１０は、１つであってもよい。 In Example 1, the example which uses denture 1 as a complete denture was shown. However, the partial denture 101 may be sufficient as a denture, as shown in FIG. In this case, the number of insertion pins 10 may be one.
実施例１では、挿入ピン本体１０ａは、側部３ｂの裏面から、装着者から見て後方に、水平方向に延びるように形成される例を示した。しかし、挿入ピン本体は、側部３ｂの裏面から、装着者から見て後方に、水平方向に対して傾斜した方向に延びるように形成されてもよい。 In Example 1, the insertion pin main body 10a showed the example formed so that it might extend in a horizontal direction back from the back surface of the side part 3b seeing from a wearer. However, the insertion pin main body may be formed so as to extend from the back surface of the side portion 3b to the rear side as viewed from the wearer in a direction inclined with respect to the horizontal direction.
実施例１では、２つの挿入ピン１０を別体とする例を示した。しかし、挿入ピンとしては、２つの挿入ピン本体が、１つの挿入ピン基部で連結された一体の部品としてもよい。 In Example 1, the example which makes the two insertion pins 10 a different body was shown. However, the insertion pin may be an integral part in which two insertion pin main bodies are connected by one insertion pin base.
実施例１では、挿入ピン１０を２つ設ける例を示した。しかし、挿入ピンは、１つだけ設けてもよいし、３つ以上設けてもよい。 In Example 1, the example which provides the two insertion pins 10 was shown. However, only one insertion pin may be provided, or three or more insertion pins may be provided.
実施例１では、義歯１を下顎用とする例を示した。しかし、義歯としては、上顎用であってもよい。 In Example 1, the example which uses denture 1 for the lower jaw was shown. However, the denture may be used for the upper jaw.
