Description

本発明は、インプラントの上部構造体に設けられたねじ部品の取付け穴に挿入され、取付け穴の穴底に露出するねじ部品のねじ頭部に係合してねじ部品のゆるみ止めを図るゆるみ止め部材に関する。   The present invention relates to a locking device that is inserted into a mounting hole of a screw component provided in an upper structure of an implant and engages with a screw head of the screw component exposed at the bottom of the mounting hole to prevent the locking of the screw component. It relates to members.

従来のこの種のインプラントとしては、たとえば、特許文献１に記載のようなものが知られている。   As this type of conventional implant, for example, the one described in Patent Document 1 is known.

すなわち、顎骨に埋め込まれるインプラント本体に対する上部構造体の固定が、上部構造体に設けられた取付け穴内にねじ部品を挿入し、取付け穴の穴底からねじ部品をインプラント本体のねじ穴にねじ込んで締め付け固定するようになっている。固定した後、取付け穴に樹脂材（レジン）もしくはゴム材等の封止材を充填して取付け穴を封止している。   In other words, the upper structure is fixed to the implant body embedded in the jaw bone. The screw part is inserted into the mounting hole provided in the upper structure, and the screw part is screwed into the screw hole of the implant body from the bottom of the mounting hole and tightened. It is designed to be fixed. After fixing, the mounting hole is filled with a sealing material such as a resin material (resin) or a rubber material to seal the mounting hole.

しかし、取付け穴に充填される封止材は、取付け穴の穴底のねじ頭部の六角穴やマイナス溝等の工具係合部にも入り込んでしまうので、上部構造体を交換したり、固定ねじがゆるんだ際の増締めをするためには、六角穴等に詰まった封止材を削り出す必要がある。   However, the sealant that fills the mounting hole also enters the tool engagement part such as the hexagonal hole and the minus groove on the screw head at the bottom of the mounting hole, so the upper structure can be replaced or fixed. In order to perform tightening when the screw is loosened, it is necessary to cut out the sealing material clogged in the hexagonal hole or the like.

そこで、従来から取付け穴に綿等を詰めてねじ頭部の工具係合部を保護することがなされているが、綿繊維では取出しにくいので、特許文献１では、金属製の微細な繊維を取付け穴に適合するように束状に編みこんだ部材を用い、ねじ頭部に封止材が入り込まないようにしていた。   Therefore, conventionally, the attachment hole has been filled with cotton or the like to protect the tool engaging portion of the screw head. However, since it is difficult to take out with cotton fiber, Patent Document 1 attaches fine metal fibers. A member knitted in a bundle to fit the hole was used so that the sealing material did not enter the screw head.

しかし、金属製繊維束を用いたとしても、繊維の直径が２０μ〜３０μと極めて細く、繊維が切れて飛散しやすく、また、狭い取付け穴から取出しにくいという問題がある。   However, even when a metal fiber bundle is used, there are problems that the diameter of the fiber is very thin, 20 μ to 30 μ, the fiber is easily broken and scattered, and it is difficult to take out from a narrow mounting hole.

また、この種のねじ締結では、咬合圧が繰り返し作用するために、ねじの緩みが生じる場合があり、ゆるみ止めの対策が要請されている。   Further, in this type of screw fastening, since the occlusal pressure repeatedly acts, the screw may be loosened, and a countermeasure for preventing the loosening is required.

現在、インプラント治療においてインプラント本体毀損の最大の原因は「緩んで咬んでしまう事」である。緩まなくするように溶接・接着すれば毀損の問題は解消するが、取り外しが出来ることは修理・清掃のため必須である。   Currently, the biggest cause of implant body damage in implant treatment is "relaxing and biting". Welding and bonding to prevent loosening eliminates the problem of damage, but removal is essential for repair and cleaning.

すなわち、数十万回咬合する中で、緩まない事は必須であり、しかも、装着も簡易で取り外しも容易であることが要請されている。   That is, it is indispensable not to loosen during hundreds of thousands of times of occlusion, and it is required to be easily mounted and removed.

特開２００４−０３３６７４号公報JP 2004-033674 A

図１乃至図２は、本発明の実施の形態に係るインプラントの固定ねじのゆるみ止め部材を示している。
すなわち、このゆるみ止め部材１は、上部構造体１０１に設けられた円筒状の取付け穴１０２に固定ねじ１１０を挿入し、取付け穴１０２の穴底から、ねじ挿通孔を通じて固定ねじ１１０をインプラント本体１０４のねじ穴にねじ込み、固定後に取付け穴１０２が樹脂材（レジン）やゴム材等の封止材１２０で封止される構成のインプラントに使用されるものである。封止材１２０としては、紫外線硬化性樹脂等、種々の材料を利用可能である。 1 and 2 show a locking member for a fixing screw of an implant according to an embodiment of the present invention.
That is, in the locking member 1, the fixing screw 110 is inserted into a cylindrical mounting hole 102 provided in the upper structure 101, and the fixing screw 110 is inserted from the bottom of the mounting hole 102 through the screw insertion hole. The mounting hole 102 is used for an implant configured to be sealed with a sealing material 120 such as a resin material (resin) or a rubber material after being fixed. As the sealing material 120, various materials such as an ultraviolet curable resin can be used.

ゆるみ止め部材１の構成は、取付け穴１０２に挿入・離脱可能で、取付け穴１０２の内部に露出するねじ頭部１１１を覆うカバー１０を有し、カバー１０には、固定ねじ１１０を回転させるための工具の先端部が係合する工具係合部としての工具係合穴１１２に係脱可能な工具先端部に対応する形状の係合凸部２０と、取付け穴１０２の開口側に向かって延びるつまみ部３０とを備えている。
この工具係合穴１１２は、図示例では六角穴となっているが、六角穴に限定されるものではなく、四角穴等の多角形穴形状、また、マイナス溝や、プラス溝等の溝形状等、固定ねじにトルクを加えることが可能な種々の形状を採用することができる。 The structure of the locking member 1 includes a cover 10 that can be inserted into and removed from the mounting hole 102 and covers the screw head 111 exposed inside the mounting hole 102, and the cover 10 is for rotating a fixing screw 110. An engagement convex portion 20 having a shape corresponding to a tool front end portion that can be engaged with and disengaged from a tool engagement hole 112 as a tool engagement portion with which the front end portion of the tool engages, and extends toward the opening side of the mounting hole 102. And a knob part 30.
The tool engagement hole 112 is a hexagonal hole in the illustrated example, but is not limited to a hexagonal hole, and is a polygonal hole shape such as a square hole, or a groove shape such as a minus groove or a plus groove. For example, various shapes that can apply torque to the fixing screw can be adopted.

ゆるみ止め部材１の材料としては、生体親和性のよい金属材、たとえばチタン等を用いることができる。もっとも、金属に限定されるものではなく、プラスチックス、セラミックス等、歯科材料として用いられる各種材料を利用可能である。
カバー１０の形状は、円板形状で、この例では、作業性を考慮して取付け穴１０２より僅かに小径で、隙間は封止材１２０が浸入しない程度とされる。 As a material for the locking member 1, a metal material having good biocompatibility, such as titanium, can be used. However, it is not limited to metals, and various materials used as dental materials such as plastics and ceramics can be used.
The shape of the cover 10 is a disc shape. In this example, the diameter is slightly smaller than the mounting hole 102 in consideration of workability, and the gap is set so that the sealing material 120 does not enter.

つまみ部３０は丸軸で、取付け穴１０２の深さよりも長く、カバー１０がねじ頭部１１１に係合した状態で、つまみ部３０の軸端が取付け穴１０２の開口部から突出するようになっており、装着時には、突出部分が切断される。
そして、固定時には、カバー１０に設けられた係合凸部２０をねじ頭部１１１に係合させて一体回転可能とし、前記カバー本体１０及びつまみ部３０と取付け穴１０２内周面間に充填される封止材１２０によって、固定ねじ１１０のゆるみ止めが図れている。
The knob portion 30 is a round shaft that is longer than the depth of the mounting hole 102, and the shaft end of the knob portion 30 protrudes from the opening of the mounting hole 102 in a state where the cover 10 is engaged with the screw head 111. The protruding part is cut at the time of mounting.
At the time of fixing, the engaging convex portion 20 provided on the cover 10 is engaged with the screw head 111 so as to be integrally rotatable, and is filled between the cover main body 10 and the knob portion 30 and the inner peripheral surface of the mounting hole 102. By means of the sealing material 120, the fixing screw 110 is prevented from loosening.

図示例では、つまみ部３０は丸軸で、基本的に六角形状の係合凸部の中心軸と同軸的に構成されているので、つまみ部３０が固定ねじ１１０の回転軸と同軸的に配置されることになるので、固定ねじ１１０がゆるむ方向の回転変位に対しては、封止材１２０とつまみ部３０表面との間の摩擦力及び接着力による。   In the illustrated example, the knob portion 30 is a round shaft and is basically configured coaxially with the central axis of the hexagonal engagement convex portion, so that the knob portion 30 is arranged coaxially with the rotation axis of the fixing screw 110. Therefore, the rotational displacement in the direction in which the fixing screw 110 is loosened depends on the frictional force and the adhesive force between the sealing material 120 and the knob part 30 surface.

つまみ部３０の表面には、図１（Ｆ）〜（Ｈ）に示すように、回転を規制するように、環状溝３０ａや、つまみ部３０の軸方向に延びる縦溝３０ｂや、螺旋溝３０ｃなどを設け、封止材１２０が係合していることが望ましい。このようなつまみ部３０表面の性状は、装着時にハンドピース工具によって削り出すようにしてもよい。   As shown in FIGS. 1 (F) to 1 (H), on the surface of the knob part 30, an annular groove 30a, a longitudinal groove 30b extending in the axial direction of the knob part 30, and a spiral groove 30c are provided so as to restrict rotation. It is desirable that the sealing material 120 is engaged. Such a property of the surface of the knob portion 30 may be cut out by a handpiece tool at the time of mounting.

つまみ部３０の変形例
つまみ部３０の断面形状は円形に限らず、一部に溝のある円形断面のつまみ部３０Ｉ（図１（Ｉ）参照）、あるいは一部に凸部のある円形断面のつまみ部３０Ｊ（図１（Ｊ）参照）、楕円形状等の非円形断面のつまみ部３０Ｋ（図１（Ｋ）参照）、四角形断面のつまみ部３０Ｌ（図１（Ｌ）参照）、六角形断面のつまみ部３０Ｌ（図１（Ｍ）参照）等の多角形状、十字形状等の放射形状のつまみ部３０Ｎ（等の図１（Ｎ）参照）としてもよい。
このように非円形断面とすることにより、回り止め効果を高くすることができる。 Modification of Knob 30 The cross-sectional shape of the knob 30 is not limited to a circle, but a knob 30I having a circular cross section with a groove in part (see FIG. 1 (I)) or a circular cross section having a convex in part. Knob portion 30J (see FIG. 1 (J)), oval shaped non-circular cross section knob portion 30K (see FIG. 1 (K)), square cross section knob portion 30L (see FIG. 1 (L)), hexagonal cross section The knob portion 30L (see FIG. 1 (N)) having a radial shape such as a polygonal shape or a cross shape may be used.
Thus, the non-circular cross section can enhance the anti-rotation effect.

より回り止め効果を高めるために、図１（Ｏ）および（Ｐ）に示すように板形状としてもよい。板形状の場合、典型的には一枚の平板構造のつまみ部３０（Ｏ）（図１（Ｏ）参照）、複数枚の板状部が放射状に配置された放射板構造のつまみ部３０Ｐの形態とすることができる（図１（Ｐ）参照）。
さらに、直線状の軸や板状とするだけでなく、図１（Ｑ）に示すように、ジグザグ形状のつまみ部３０Ｑとしてもよい。このようにジグザグ形状とすることにより、つまみ部３０Ｑが封止材１２０とよく絡み合い、回り止め効果を高くすることができる。
In order to enhance the anti-rotation effect, a plate shape may be used as shown in FIGS. 1 (O) and (P). In the case of a plate shape, typically, the tab portion 30 (O) having a single flat plate structure (see FIG. 1 (O)), and the tab portion 30P having a radial plate structure in which a plurality of plate-like portions are radially arranged. it is the form and to Turkey (see FIG. 1 (P)).
Further, not only a linear shaft or plate shape but also a zigzag knob portion 30Q may be used as shown in FIG. By making the zigzag shape in this way, the knob portion 30Q is intertwined with the sealing material 120, and the anti-rotation effect can be enhanced.

なお、つまみ部３０が丸軸であっても、中心軸を、係合凸部の中心軸とオフセットさせておけば、封止材１２０によってつまみ部３０の回転が規制され、固定ねじの回り止めを図ることができる。さらに、つまみ部３０が丸軸であっても、カバー１０に凸部や凹部を設けることによっても、回り止め効果を高めることができる。   Even if the knob portion 30 is a round shaft, if the center axis is offset from the center axis of the engaging convex portion, the rotation of the knob portion 30 is restricted by the sealing material 120 and the rotation of the fixing screw is prevented. Can be achieved. Furthermore, even if the knob part 30 is a round shaft, the anti-rotation effect can be enhanced by providing the cover 10 with a convex part or a concave part.

作業手順
次に作業手順について説明する。
図２は、ゆるみ止め部材の装着手順である。
歯冠がかぶせられた上部構造体１０１の取付け穴１０２に固定ねじ１１０を挿入し、取付け穴１０２の穴底から顎骨に埋設されたインプラント本体１０４に固定ねじ１１０をねじ込んで固定する（図２（Ａ）参照）。 Work Procedure Next, the work procedure will be described.
FIG. 2 shows a procedure for mounting the locking member.
The fixing screw 110 is inserted into the mounting hole 102 of the superstructure 101 covered with the crown, and the fixing screw 110 is screwed into the implant body 104 embedded in the jawbone from the bottom of the mounting hole 102 and fixed (FIG. 2 ( A)).

次に、図２（Ｂ）に示すように、取付け穴１０２内に、本発明のゆるみ止め部材１を挿入する。挿入は、つまみ部３０を手指やピンセット等でつまんで挿入し、穴底のねじ頭部１１１に突き当てる。突き当てた後、回転させて六角穴１１２を探る。係合凸部２０が六角穴１１２に嵌り込むと、ゆるみ止め部材１は一段奥に入り込んで回転しなくなるので、
作業者は六角穴１１２に係合したことが分かる。次に、つまみ部３０と取付け穴１０２の間の隙間に、熱により溶融した封止材１２０を充填する。封止材１２０としては、紫外線硬化樹脂が用いられ、紫外線を照射することにより硬化させる（図２（Ｃ）参照）。
このつまみ部３０の表面に、工具によって、適宜、縦溝、環状溝、螺旋溝等を形成することが可能である。また、取付け穴内周にも溝等を加工すれば、回り止め効果をより高めることが可能である。さらに、封止材１２０の抜け止めを図るために、取付け穴内周にオーバーハング部を加工するようにしてもよい。
つまみ部３０は取付け穴１０２より外部に突出しており、この突出部３０Ｙを工具で切断し（図２（Ｄ）参照）、封止材１２０と共に歯冠表面と滑らかに連続する連続面となるように研磨する。 Next, as shown in FIG. 2B, the locking member 1 of the present invention is inserted into the mounting hole 102. The insertion is performed by pinching the knob part 30 with fingers or tweezers and butting it against the screw head 111 at the bottom of the hole. After abutment, rotate to find the hexagonal hole 112. When the engaging convex portion 20 is fitted into the hexagonal hole 112, the loosening prevention member 1 enters the back and stops rotating.
It can be seen that the operator has engaged the hexagonal hole 112. Next, the gap between the knob portion 30 and the mounting hole 102 is filled with the sealing material 120 melted by heat. As the sealing material 120, an ultraviolet curable resin is used and cured by irradiation with ultraviolet rays (see FIG. 2C).
A vertical groove, an annular groove, a spiral groove, or the like can be appropriately formed on the surface of the knob portion 30 with a tool. Further, if a groove or the like is machined in the inner periphery of the mounting hole, the effect of preventing rotation can be further enhanced. Furthermore, in order to prevent the sealing material 120 from coming off, an overhang portion may be processed on the inner periphery of the attachment hole.
The knob portion 30 protrudes to the outside from the mounting hole 102, and this protruding portion 30Y is cut with a tool (see FIG. 2D) so that it becomes a continuous surface smoothly continuous with the crown surface together with the sealing material 120. To polish.

このようにすれば、カバー１０及びつまみ部３０の表面と取付け穴１０２の内周面に間の空間に充填された封止材１２０を介して、固定ねじ１１０の回転が規制され、固定ねじ１１０のゆるみ止めを図ることができる。   In this way, the rotation of the fixing screw 110 is regulated through the sealing material 120 filled in the space between the surface of the cover 10 and the knob portion 30 and the inner peripheral surface of the mounting hole 102, and the fixing screw 110 is controlled. Can be prevented.

仮に、固定ねじ１１０がゆるんだ場合、本実施の形態ではつまみ部３０の先端が歯冠の表面と連続面に研磨しているので、外部からゆるんだかどうかを客観的に判断する指標とすることが可能となる。また、このような段差は、患者本人がすぐに違和感を感じ、感覚的に気付きやすく、「かめなくなる」ため医院に来院するので、修理がすぐに可能であるという利点がある。   If the fixing screw 110 is loosened, in this embodiment, the tip of the knob portion 30 is polished to a continuous surface with the surface of the crown, so that it is used as an index for objectively judging whether or not it is loosened from the outside. Is possible. In addition, such a step has an advantage that the patient himself immediately feels uncomfortable, easily perceives sensuously, and “cannot bite”, so he / she visits the clinic and can be repaired immediately.

図３は、固定ねじ１１０が緩んだ場合の増締め、あるいは歯冠を交換する場合の固定ねじ１１０の取り外し手順を示している。
まず、図３（Ａ）に示すように、取り付け穴１０２に充填された封止材１２０を、ハンドピース工具によって削り出し、つまみ部３０を露出させる（図３（Ａ）、（Ｂ）参照）。この露出したつまみ部３０をつまんで、ゆるみ止め部材１を取付け穴１０２から取出し、固定ねじ１１０のねじ頭部１１１を露出させる（図３（Ｃ）参照）。削り出す部分は、封止材１２０を取り付け穴１０２内周面から離間させればよく、つまみ部３０に封止材が付着していてもよい。 FIG. 3 shows a procedure for removing the fixing screw 110 when the fixing screw 110 is loosened or when the crown is replaced.
First, as shown in FIG. 3A, the sealing material 120 filled in the mounting hole 102 is cut out by a handpiece tool to expose the knob portion 30 (see FIGS. 3A and 3B). . The exposed knob portion 30 is pinched to take out the locking member 1 from the mounting hole 102 and expose the screw head 111 of the fixing screw 110 (see FIG. 3C). The part to be cut out may be formed by separating the sealing material 120 from the inner peripheral surface of the mounting hole 102, and the sealing material may be attached to the knob portion 30.

ゆるみ止め部材１を取出した後、固定ねじを工具を用いて増す締め、あるいは取り外す。固定ねじ１１０のねじ頭部１１１はゆるみ止め部材１によって覆われ、露出した六角穴１１２には封止材１２０が入り込んでいないので、固定ねじ１１０の増締め、あるいは取り外しを簡単に行うことができる。   After removing the locking member 1, the fixing screw is tightened or removed using a tool. Since the screw head 111 of the fixing screw 110 is covered with the locking member 1 and the sealing material 120 does not enter the exposed hexagonal hole 112, the fixing screw 110 can be easily tightened or removed. .

なお、固定ねじ１１０のねじ頭部１１１の長さを長くしておけば、取付け穴１０２の咬
合面からのねじ頭部１１１までの長さが短くなるので、ゆるみ止め部材１の長さを短くでき、また樹脂材等の封止材の充填量も少なく、作業も容易となる。
 Incidentally, if a longer length of the screw head 111 of the solid Teineji 110, the length up to the screw head 111 from the occlusal surface of the mounting hole 102 becomes shorter, the length of the locking member 1 It can be shortened, and the filling amount of a sealing material such as a resin material is small, and the operation becomes easy.
