Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は歯の欠損部を補填する義歯に関する。TECHNICAL FIELD The present invention relates to a denture for filling a tooth defect.
従来、歯の欠損部を補填する場合、欠損部の両側に健全
な生存歯が存在する場合には、いわゆるブリッジによる
義歯を用いていた。Conventionally, in the case of filling a defective portion of a tooth, when there are healthy living teeth on both sides of the defective portion, a so-called bridge denture has been used.
ブリッジは両側の生存歯を支台歯として利用するもの
で、支台歯は、その外殻歯質を削って小さくするととも
に、義歯側は、支台歯を覆う一対の装着部と各装着部の
間に位置する義歯本体を一体に形成し、装着時に、義歯
の各装着部を支台歯に嵌め込み、さらに、接着剤により
固着していた。The bridge uses the living teeth on both sides as abutment teeth, and the abutment teeth are ground to reduce the outer dentin, and the denture side has a pair of attachment parts covering each abutment tooth and each attachment part. The main body of the denture located between the dentures is integrally formed, and at the time of mounting, each mounting portion of the denture is fitted into the abutment tooth and further fixed by an adhesive.
しかし、このような従来の義歯は支台歯をかなり削り取
る必要があるとともに、場合によっては歯髄に及ぶこと
もあり、健全な歯を傷付ける致命的な欠点があった。However, such a conventional denture has a fatal drawback of damaging a healthy tooth, since it is necessary to considerably scrape off the abutment tooth, and in some cases, it may reach the pulp.
本発明はこのような従来技術に存在する課題を解決した
義歯の提供を目的とするものである。The present invention aims to provide a denture that solves the problems existing in the related art.
本発明に係る義歯１は、義歯本体２を前後に二分割した
前半体2fと後半体2rにより構成し、かつ位置決め部６を
介して結合可能に構成するとともに、前半体2fと後半体
2rの側面に、各生存歯Ha、Hbの外部側面に嵌着可能な嵌
着部4a、4bを設けることにより、義歯本体２の両側を凹
状に形成したことを特徴とする。The denture 1 according to the present invention is configured by a front half 2f and a rear half 2r, which are obtained by dividing a denture main body 2 into two parts in the front and rear directions, and is configured to be connectable via a positioning portion 6, and the front half 2f and the half half.
It is characterized in that both sides of the denture main body 2 are formed in a concave shape by providing fitting portions 4a and 4b that can be fitted to the outer side surfaces of the living teeth Ha and Hb on the side surface of 2r.
本発明に係る義歯１によれば、義歯本体２に設けた嵌着
部4a、4bは、義歯本体２の両側に位置するそのままの生
存歯Ha、Hbに直接嵌着し、義歯本体２が固定されるとと
もに、欠損部を補填する。According to the denture 1 according to the present invention, the fitting portions 4a and 4b provided on the denture body 2 are directly fitted to the living teeth Ha and Hb, which are located on both sides of the denture body 2, and the denture body 2 is fixed. At the same time, the defective part is filled up.
次に、本発明に係る好適な実施例を挙げ、第１図〜第４
図を参照して詳細に説明する。Next, preferred examples according to the present invention will be given, and FIGS.
This will be described in detail with reference to the drawings.
図中、Ha、Hbは健全な生存歯を示し、また、その間は一
本の歯が欠損している状態を示している。In the figure, Ha and Hb show healthy living teeth, and one tooth is missing during that period.
一方、２は義歯本体であり、この義歯本体２の両側面
に、各生存歯Ha、Hbの側面に嵌着可能な凹状に湾曲した
嵌着部4a、4bを一体に設ける。また、義歯本体２は前後
に二分割した前半体2fと後半体2rにより構成し、装着時
には両者を結合可能に構成する。各半体2f、2rの側面形
状は、両側に位置する生存歯Ha、Hbにおける側面形状と
一致するように同一に形成する。この場合、生存歯Ha、
Hbの側面は曲面形状をなすとともに、付根側は幅が狭く
なっているため、装着時には各半体2f、2rの側面が生存
歯Ha、Hbの側面にそれぞれ嵌着して固定される嵌着部4
a、4bが構成される。On the other hand, 2 is a denture main body, and on both side surfaces of the denture main body 2, concavely curved fitting portions 4a and 4b which can be fitted to the side surfaces of the living teeth Ha and Hb are integrally provided. Further, the denture main body 2 is composed of an anterior half body 2f and a posterior half body 2r, which are divided into two parts in the front and rear, and are configured to be connectable to each other at the time of mounting. The side shapes of the halves 2f and 2r are formed to be the same as the side shapes of the living teeth Ha and Hb located on both sides. In this case, the living tooth Ha,
Since the side surface of Hb has a curved shape and the width at the root side is narrow, the side surface of each half 2f, 2r is fitted and fixed to the side surface of the living tooth Ha, Hb when mounted. Part 4
a and 4b are configured.
また、前半体2fと後半体2rには位置決め部６を設ける。
即ち、前半体2fの対向面には突起部12a、12bを設けると
ともに、後半体2rの対向面には突起部12a、12bが挿入す
る穴部13a、13bを設ける。なお、突起部12a…（穴部13a
…）は先端下がりに形成し、必要により第４図符号12bs
で示す仮想線のようにテーパを設けてもよい。このよう
なテーパを設けることにより、着脱が容易となる利点が
ある。また、突起部12a…を有する前半体2fの上端には
突片部14を一体に形成するとともに、後半体2rの上端に
は当該突片部14が嵌合する凹部15を設ける。Further, a positioning portion 6 is provided on the front half 2f and the rear half 2r.
That is, the protrusions 12a and 12b are provided on the opposing surface of the front half 2f, and the holes 13a and 13b into which the protrusions 12a and 12b are inserted are provided on the opposing surface of the rear half 2r. In addition, the protrusion 12a ... (hole 13a
…) Is formed with the tip down, and if necessary, the reference numeral 12bs in Fig. 4
You may provide a taper like the virtual line shown by. Providing such a taper has an advantage that it can be easily attached and detached. Further, a protrusion piece 14 is integrally formed on the upper end of the front half body 2f having the protrusions 12a, and a recess 15 into which the protrusion piece 14 is fitted is provided on the upper end of the rear half body 2r.
よって、装着時には各半体2fと2rを第１図に示すように
それぞれ前後から突合わせ、例えば、圧入形式により着
