JP-A-60-207660 Japanese Patent No. 3541162

歯牙の齲蝕部位の除去治療において、歯牙の齲蝕形状によっては、歯牙表面の齲蝕面積より内部齲蝕の方が大きい場合がある、
従来のノズルは、ノズル先端形状が円柱形状であり、粉体と液体の混合物はノズル先端の円柱軸方向に噴射されるため、歯牙の表層の健全なエナメル質裏側の不可視領域にある齲蝕を取り残す問題があった。
また、粉体にエナメル質より硬い素材であるアルミナなどを使用することにより、不可視領域の齲蝕の上部にある歯牙のエナメル質を含めて齲蝕部位を取り除くことが容易となるが、健全な歯牙を切削しなくてはならないという問題や、研削材料であるアルミナがノズル先端部を削るという問題があった。
In the removal treatment of the carious site of the tooth, depending on the caries shape of the tooth, the internal caries may be larger than the caries area of the tooth surface,
The conventional nozzle has a cylindrical shape at the tip of the nozzle, and a mixture of powder and liquid is injected in the direction of the cylindrical axis at the tip of the nozzle, leaving behind the caries in the invisible area behind the healthy enamel on the surface of the tooth. There was a problem.
In addition, by using alumina, which is a material harder than enamel, in the powder, it becomes easy to remove the caries, including the enamel of the teeth above the caries in the invisible region, but healthy teeth can be removed. There was a problem that it had to be cut, and there was a problem that the grinding material alumina cut the tip of the nozzle.

したがって、本発明の課題は、混合物の噴射方向を拡散することにより、従来の混合物を直線的に噴射するノズルでは切削が困難であった、歯牙における不可視領域の齲蝕に対して、除去を容易にする粉体噴射装置用ノズルを提供することである。 Accordingly, an object of the present invention is to easily remove the caries in the invisible region of the tooth, which is difficult to cut with a conventional nozzle that linearly sprays the mixture, by diffusing the injection direction of the mixture. It is to provide a nozzle for a powder injection device.

本発明は歯科治療で使用するための研削用粉体と加圧気体の混合物を供給する内管と、前記内管を覆うように液体を供給する外管を備え、前記混合物と液体を歯牙に吹き付けることにより歯牙の研削を行う粉体噴射装置のハンドピースのノズルにおいて、内管の先端部に内径を絞った細管部を有し、細管部から混合物噴出孔にかけて内管を広げた混合物拡散部を有することを特徴とする歯科治療用粉体噴射装置用ノズルである。 The present invention includes an inner tube that supplies a mixture of grinding powder and pressurized gas for use in dental treatment, and an outer tube that supplies a liquid so as to cover the inner tube, and the mixture and the liquid are applied to teeth. In the nozzle of the handpiece of the powder injection device that grinds teeth by spraying, a mixture diffusing section that has a narrow tube section with a narrowed inner diameter at the tip of the inner tube and that expands the inner tube from the narrow tube section to the mixture ejection hole It is a nozzle for powder treatment apparatus for dental treatment characterized by having.

本発明の歯科治療用粉体噴射用ノズルは、歯科治療で使用するための研削用粉体と加圧気体の混合物を供給する内管と、液体を供給する外管を備え、前記混合物と前記液体を歯牙に吹き付けることにより歯牙の研削を行う粉体噴射装置のハンドピース用のノズルヘッドにおいて、
ノズルは、該内管の先端部に内径を絞った細管部を有し、細管部から混合物噴出孔にかけて内管を広げた円錐形状の混合物拡散部を有し、前記内管を覆うように外管を設け、内管の外側と外管の内側からなる空間に液体を通すための通路を有することにより、従来の混合物を直線的に噴射するノズルでは切削が困難であった歯牙における不可視領域の齲蝕に対する除去が容易になる。
The powder injection nozzle for dental treatment of the present invention comprises an inner tube for supplying a mixture of powder for grinding and pressurized gas for use in dental treatment, and an outer tube for supplying a liquid. In a nozzle head for a handpiece of a powder injection device that grinds teeth by spraying liquid on the teeth,
The nozzle has a narrow tube portion with a narrowed inner diameter at the tip of the inner tube, and has a conical mixture diffusion portion in which the inner tube is widened from the narrow tube portion to the mixture ejection hole, and is arranged so as to cover the inner tube. By providing a tube and having a passage for allowing liquid to pass through the space formed by the outer side of the inner tube and the inner side of the outer tube, it is difficult to cut with a conventional nozzle that linearly sprays the mixture. Removal against caries becomes easy.

さらに詳細に説明すると、図4に記すように、齲蝕部位41には可視領域齲蝕42と不可視領域齲蝕43がある。
従来の噴出孔が円柱形状のノズルでは、図5に記すように、ノズル先端からの研削用粉体の噴出方向51はノズル先端の円柱軸方向に平行となるため、可視領域齲蝕の削除のみが容易であり、不可視領域齲蝕の除去はノズルを傾けて噴射しなければならなかった。さらに深い不可視領域齲蝕では、ノズルを傾けても除去が困難であった。
本発明の歯科治療用粉体噴射装置用ノズルは、図6に記すように、ノズル先端からの研削用粉体の噴射方向61がノズル先端の軸方向に対し角度を持ち該軸の同心状に拡散するため、ノズルを傾けることなく不可視領域齲蝕の除去が容易となった。さらに深い不可視領域齲蝕に対しても、ノズルを傾けることにより除去できる。
More specifically, as shown in FIG. 4, the caries portion 41 includes a visible area caries 42 and an invisible area caries 43.
In a conventional nozzle having a cylindrical injection hole, as shown in FIG. 5, the ejection direction 51 of the grinding powder from the nozzle tip is parallel to the cylinder axis direction of the nozzle tip, so only the visible area caries is deleted. It was easy and removal of invisible area caries had to be sprayed with the nozzle tilted. In deeper invisible area caries, removal was difficult even if the nozzle was tilted.
As shown in FIG. 6, the nozzle for dental treatment powder injection device of the present invention is such that the injection direction 61 of the powder for grinding from the nozzle tip has an angle with respect to the axial direction of the nozzle tip and is concentric with the shaft. Due to the diffusion, the invisible area caries can be easily removed without tilting the nozzle. Even deeper invisible area caries can be removed by tilting the nozzle.

ノズルの先端部の内管の絞った細管部は、研削用粉体と加圧気体の混合物の通路であり、混合物の噴出速度は該通路の最小径と加圧気体の圧力および流量により決まる。

In order to eliminate clogging of the mixture of the grinding powder and the pressurized gas, the length of the narrow tube portion is preferably 10 mm or less. More preferably, it is 3 mm or less.
Since the operability is improved by reducing the outer diameter of the nozzle, the inner diameter of the mixture ejection hole at the tip of the nozzle is preferably φ0.5 to 1.5 mm. More preferably, it is φ0.5 to 1.0 mm.

ノズル先端の混合物拡散部の円錐形状の拡散角度は、好ましくは3〜50度であり、さらに好ましくは5〜30度である。 The cone-shaped diffusion angle of the mixture diffusing portion at the nozzle tip is preferably 3 to 50 degrees, and more preferably 5 to 30 degrees.
