Description
【0001】[0001]
本考案は永久磁石による磁気吸引力を利用して義歯を保持する補綴方法に使用 するための義歯安定用保持板に関するものである。 The present invention relates to a holding plate for stabilizing a denture for use in a prosthetic method for holding a denture by using a magnetic attraction force of a permanent magnet.
【0002】[0002]
義歯を口腔内に固定するに際して、永久磁石と軟磁性合金との間に作用する磁 気吸引力を利用する試みは従来からすでに種々行なわれており、例えば「T.R .Jackson:オッセオインテグレーテッド・インプラントに対しての希土 類磁石による維持装置の応用、オーラル・マキシロフェイシャル・インプラント 、Vol.1(1987)、No. 2、77〜89頁」に種々記載されている。 Various attempts have been made in the past to utilize the magnetic attraction force acting between a permanent magnet and a soft magnetic alloy when fixing a denture in the oral cavity, for example, “TR Jackson: Osseo Integrate”. Application of Rare Earth Magnet Sustaining Device to Ted Implant, Oral Maxirofacial Implant, Vol. 1 (1987), No. 2, pp. 77-89 ”.
【0003】 図3は永久磁石の磁気吸引力を利用した義歯固定手段の例を示す要部縦断面図 である。図3において、2は根面部材であり、例えば金合金のような耐食性非磁 性材料により、例えば縦断面形状をT字形に形成すると共に、歯根3内に埋設す る。1は保持板であり、例えばSUS447J1のような耐食性磁性ステンレス 鋼により円板状に形成して、根面部材2の端部に鋳ぐるみにより一体に埋設する 。FIG. 3 is a longitudinal sectional view of an essential part showing an example of artificial tooth fixing means utilizing the magnetic attraction force of a permanent magnet. In FIG. 3, reference numeral 2 denotes a root member, which is made of, for example, a corrosion-resistant non-magnetic material such as a gold alloy and has a vertical cross section of T-shape and is embedded in the tooth root 3. Reference numeral 1 denotes a holding plate, which is formed in a disk shape from corrosion-resistant magnetic stainless steel such as SUS447J1 and is integrally embedded in the end portion of the root member 2 by means of a cast member.
【0004】 次に4は義歯床であり、義歯5を植設すると共に前記根面部材2と対向するよ うに永久磁石組立体6を埋設してある。永久磁石組立体6は、例えば耐食性磁性 ステンレス鋼からなるケース7内に永久磁石8を蓋板9を介して密閉封止して形 成する。上記の構成により、永久磁石組立体6と保持板1との間には磁気的吸引 力が作用し、この磁気的吸引力によって義歯床4は歯根3に押し付けられ、義歯 5を口腔内に安定させることができるのである。Next, 4 is a denture base, in which a denture 5 is implanted and a permanent magnet assembly 6 is embedded so as to face the root member 2. The permanent magnet assembly 6 is formed by hermetically sealing a permanent magnet 8 via a cover plate 9 in a case 7 made of, for example, corrosion-resistant magnetic stainless steel. With the above structure, a magnetic attractive force acts between the permanent magnet assembly 6 and the holding plate 1, and the denture base 4 is pressed against the root 3 by this magnetic attractive force, so that the denture 5 can be stably held in the oral cavity. It can be done.
【0005】[0005]
上記構成の保持板1は、例えば金合金のような耐食性非磁性材料からなる根面 部材2によって抱持されているのみであり、保持板3の外周面と、前記根面部材 1との間の摩擦力によって保持されているので、根面部材2に印加される噛合力 により、根面部材2と保持板1との間の軸方向相対移動を助長する作用が加わる ため、使用中に根面部材2と保持板1との間に相対的移動が発生するという問題 点がある。 本考案は上記従来技術に存在する問題点を解決し、根面部材による抱持力を増 大させ得る義歯安定用保持板を提供することを目的とする。 The holding plate 1 having the above structure is only held by the root member 2 made of a corrosion-resistant non-magnetic material such as a gold alloy, and is held between the outer peripheral surface of the holding plate 3 and the root member 1. Since it is held by the frictional force of the root surface member 2, the meshing force applied to the root surface member 2 has an effect of promoting relative movement in the axial direction between the root surface member 2 and the holding plate 1. There is a problem that relative movement occurs between the surface member 2 and the holding plate 1. An object of the present invention is to provide a holding plate for stabilizing a denture, which can solve the problems existing in the above-mentioned prior art and can increase the holding force of the root surface member.
【0006】[0006]
上記目的を達成するために、本考案においては、歯根内に埋設された非磁性材 料からなる根面部材の端面に、義歯床に埋設した永久磁石組立体と対向して鋳接 される軟磁性材料からなる義歯安定用保持板において、外周面に周方向溝を設け るという技術的手段を採用した。周方向溝は、深さ0.02mm以上、ピッチ1 .0mm以下であることが望ましい。溝の深さが0.02mm以上であると十分 な抱持力若しくは耐引抜力を得ることができる。 次にピッチが1.0mmを越えると、刻設される周溝の存在しない保持板が生 成する場合がある。上記の構成により、根面部材による保持板に対する抱持力若 しくは耐引抜力を増大させることができるのである。 In order to achieve the above-mentioned object, in the present invention, the end face of the root member made of a non-magnetic material embedded in the root of the tooth is soft-cast by facing the permanent magnet assembly embedded in the denture base. In the holding plate for stabilizing dentures made of a magnetic material, a technical means of providing a circumferential groove on the outer peripheral surface is adopted. The circumferential groove has a depth of 0.02 mm or more and a pitch of 1. It is preferably 0 mm or less. When the depth of the groove is 0.02 mm or more, sufficient holding force or pullout resistance can be obtained. Next, if the pitch exceeds 1.0 mm, a holding plate having no engraved peripheral groove may be formed. With the above structure, it is possible to increase the holding force or pullout resistance of the root surface member with respect to the holding plate.
【0007】[0007]
図1は本考案の実施例を示す縦断面図である。図1において10は周溝であり 、保持板の外周面に円周方向に設ける。なおtは、周溝10の深さ寸法でありp は、周溝10のピッチ寸法である。この場合保持板1はフェライト系ステンレス 鋼(磁性)、例えばSUS447J1により外径4.4mm、高さ1mmに形成 し、pは0.5mm、tは0.1mmに形成した。 表1は図1における周溝10の深さtおよびピッチpを変えた場合の耐引抜力 の値を示す表である。 なお、比較例として図2に示す従来のものに対する結果をNo.10として併 記した。 FIG. 1 is a vertical sectional view showing an embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a circumferential groove, which is provided on the outer peripheral surface of the holding plate in the circumferential direction. Note that t is the depth dimension of the circumferential groove 10 and p is the pitch dimension of the circumferential groove 10. In this case, the holding plate 1 was made of ferritic stainless steel (magnetic) such as SUS447J1 to have an outer diameter of 4.4 mm and a height of 1 mm, p was 0.5 mm, and t was 0.1 mm. Table 1 is a table showing the values of the pulling-out resistance when the depth t and the pitch p of the circumferential groove 10 in FIG. 1 are changed. As a comparative example, the results for the conventional example shown in FIG. It is also shown as 10.
【0008】[0008]
【表1】 表1から明らかなように、No1〜9においては、何れも比較例であるNo10 のものより耐引抜力が大なる値を示しており、図1に示す周溝10を設けた効果 が現れている。 なお、周溝10の深さ寸法がわになるにつれて、およびピッチ寸法が大になる につれて、耐引抜力が低下する傾向がある。[Table 1] As is clear from Table 1, in Nos. 1 to 9, the pulling resistance is larger than that of No. 10 which is a comparative example, and the effect of providing the circumferential groove 10 shown in FIG. There is. The pull-out resistance tends to decrease as the depth of the circumferential groove 10 becomes known and as the pitch increases.
