Abstract
Description
この発明は、歯科矯正用支持体に関するものである。 The present invention relates to an orthodontic support.
歯科矯正治療は様々な方法で行われているが、歯を移動させるためには、移動力を加えるための付勢手段と、それを固定保持するための支点(固定源)が必要である。 Orthodontic treatment is performed by various methods. In order to move a tooth, a biasing means for applying a moving force and a fulcrum (fixing source) for fixing and holding the moving force are required.
付勢手段としては、例えばゴムや板バネ等が用いられている。特許文献1を参照。 As the biasing means, for example, rubber, a leaf spring, or the like is used. See Patent Document 1.
また、固定源としては、大臼歯を用いることが多かった。しかし、その場合には、前歯部や小臼歯の移動は行えるが、大臼歯自体を移動することは極めて困難であった。 In addition, molars were often used as a fixing source. However, in this case, it is possible to move the front teeth and the premolars, but it is extremely difficult to move the molars themselves.
固定源を口腔外(顎外)に求める方法も実施されている。例えば、頭部にヘッドギアを付けたり、首にネックバンドを装着して固定源するのである。しかし、このような方法では、顎外に固定装置が配置されるため、治療の成果が患者の協力度に左右される。また、何らかの外的要因によって固定装置が外れることもあった。
前述のような不具合を解消するため、骨内インプラントを応用して、インプラント体を固定源とする方法も行われている。 In order to solve the above-mentioned problems, a method of using an implant body as a fixing source by applying an intraosseous implant has been performed.
インプラント法は、骨内にインプラント体を植立し、骨としっかり固着させた後で、その口腔内露出部を固定源とする方法である。 The implant method is a method in which an implant body is implanted in a bone and firmly fixed to the bone, and the exposed portion in the oral cavity is used as a fixing source.
しかし、インプラント法では、ネジ状または棒状のインプラント体を直接骨に植え込んだ後で、インプラント体が骨にしっかりと固着されるまで、治療を待たねばならなかった。 However, according to the implant method, after implanting the screw-shaped or rod-shaped implant directly into the bone, treatment must be waited until the implant is firmly fixed to the bone.
また、従来のインプラント体では、痛みや違和感を伴うことがあり、除去時に粘膜を傷付ける恐れもあった。 In addition, the conventional implant body may be accompanied by pain or discomfort, and may cause damage to the mucous membrane during removal.
さらに、固定源として、形成外科の骨接合用として用いられるミニプレートを転用する方法もある。しかしながら、形成外科用のミニプレートは、口腔内露出を考慮して作られていないため、全てネジ穴が連絡したデザインになっていて、フック部が無いため、取扱いが面倒であった。 Further, there is a method of diverting a mini plate used for osteosynthesis in plastic surgery as a fixing source. However, plastic mini-plates for plastic surgery have not been made in consideration of exposure in the oral cavity, so that all screw holes are designed to communicate with each other, and there is no hook portion, so handling is troublesome.
このような従来技術の問題点に鑑み、本発明は、上下顎大臼歯の近遠心移動や圧下等の3次元的コントロールを任意に行うことができ、植立及び撤去が容易であって、術後感染や除去時の粘膜損傷の恐れが少なく、痛みや違和感を最小限に抑えることができる歯科矯正用支持体を提供することを目的としている。 In view of the problems of the prior art described above, the present invention can arbitrarily perform three-dimensional control such as mesio-distal movement and reduction of upper and lower molars, and can be easily implanted and removed. An object of the present invention is to provide a support for orthodontics, which has a low risk of mucous membrane damage during post-infection or removal, and can minimize pain and discomfort.
本発明は、顎骨に固定する固定部(21)と、口腔内に露出する露出部(23)と、固定部(21)および露出部(23)の間に位置し可動粘膜を貫通する可動粘膜貫通部(22)とを備え、全体的にプレートで形成されており、複数のネジ止め用穴(14、24)が固定部(21)のみに形成されており、矯正力を与えるバネやゴム(19)を係止するための複数の連続した係止部(25)が露出部(13、23)に設けられており、その係止部(25)が複数の連続した突起(25)で構成されており、それらの突起(25)が可動粘膜貫通部(22)の両側に突出していることを特徴とする歯科矯正用支持体を要旨としている。 The present invention provides a fixing part (21) for fixing to a jaw bone, an exposed part (23) exposed in the oral cavity, and a movable mucous membrane located between the fixing part (21) and the exposed part (23) and penetrating the movable mucous membrane. A plurality of screw holes (14, 24) are formed only in the fixing portion (21), and a spring or rubber for giving a correcting force is provided. A plurality of continuous locking portions (25) for locking (19) are provided on the exposed portions (13, 23), and the locking portion (25) is formed by a plurality of continuous projections (25). The gist of the present invention is a support for orthodontics, wherein the protrusions (25) protrude on both sides of the movable mucous membrane penetrating portion (22).
本発明の歯科矯正用支持体によれば、上下顎大臼歯の3次元的コントロールを任意に行うことができ、術後感染や除去時の粘膜損傷の恐れが少なく、痛みや違和感を最小限に抑えることができる。 ADVANTAGE OF THE INVENTION According to the orthodontic support of this invention, three-dimensional control of upper and lower molars can be performed arbitrarily, there is little possibility of mucosal damage at the time of postoperative infection or removal, and pain and discomfort are minimized. Can be suppressed.
複数のネジ止め用穴を固定部のみに形成した場合には、植立及び撤去が容易であって、支持体植立直後でも固定源として歯芽移動治療を開始できる。 When a plurality of screw holes are formed only in the fixing portion, the implantation and removal are easy, and the tooth bud migration treatment can be started as a fixing source immediately after the support is planted.
バネやゴムを係止するための複数の連続した係止部として複数の連続した突起を露出部に設けるので、係止に使用しない係止部の一部を除去できる。そのため、係止部の所望の位置から移動力を掛けることができ、かつ、不用の係止部を容易にカットできる。その結果、機能的マイナス無しに必要な係止部分のみを残すことが可能である。 Since a plurality of continuous projections are provided on the exposed portion as a plurality of continuous locking portions for locking a spring or rubber, a part of the locking portion not used for locking can be removed. Therefore, a moving force can be applied from a desired position of the locking portion, and unnecessary locking portions can be easily cut. As a result, it is possible to leave only the necessary locking portions without any functional minus.
矯正力を与えるバネやゴムを係止するための複数の連続した係止部を露出部に設け、係止部の不用の部分を除去できる構成にすると良い。 It is preferable that a plurality of continuous locking portions for locking a spring or a rubber for applying a correcting force be provided on the exposed portion so that unnecessary portions of the locking portion can be removed.
一連の突起(2連以上の突起)によって係止部を構成する。 The locking portion is constituted by a series of projections (two or more projections).
本発明の支持体の材質としては、生体に対して害の少ない材料例えばチタン、チタン合金、ステンレス合金などが好ましい。 As the material of the support of the present invention, a material that is less harmful to the living body, such as titanium, a titanium alloy, and a stainless alloy, is preferable.
