Abstract
Description
本発明は、歯科用チップ、より詳細には、歯科治療において、歯の側面に差し込んで振動させ、埋没歯や折れた歯根を掘り起こして抜くのに使用して好適な歯科用チップに関する。 The present invention relates to a dental tip, and more particularly, to a dental tip suitable for use in dentistry by inserting it into a side surface of a tooth and causing it to vibrate to dig up and remove an embedded tooth or a broken root.
歯科治療においては、しばしば抜歯を行うが、従来、この抜歯は、抜歯鉗子を用いて行われている。この抜歯鉗子は、歯を把握し、動揺させて、脱臼させ、次いで、牽引抜去するもので、前歯,小臼歯,大臼歯,残根用と、上顎,下顎,乳歯,永久歯用等々多種あるが、いずれも、歯を把持する嘴部と、手指および手掌で把握する把柄部と、さらに、両部を連結する関節部よりなるが、埋没歯や折れた歯根等は、把持しにくく、使い勝手が悪かった。 In dental treatment, tooth extraction is often performed. Conventionally, this tooth extraction is performed using extraction forceps. This extraction forceps grasps, shakes, dislocations, and then pulls out, and is used for anterior teeth, premolars, molars, residual roots, maxilla, mandibular, deciduous teeth, permanent teeth, etc. Each of these consists of a buttocks that grips the teeth, a handle that is grasped by fingers and palms, and a joint that connects the two parts. However, embedded teeth and broken roots are difficult to grasp and It was bad.
本発明は、上述のごとき実情に鑑みてなされたもので、特に、埋没歯や折れた歯根等、鉗子では掴みにくい歯牙を、振動させ、掴むことなく、効果的に抜歯することができ、更には、歯牙等骨の表面を削り、削った骨片をかき集め、所望の箇所へ移動させるのに好適な歯科治療具を提供することを目的としてなされたものである。 The present invention has been made in view of the above circumstances, and in particular, teeth that are difficult to grasp with forceps, such as embedded teeth and broken roots, can be effectively extracted without being vibrated and gripped. The purpose of this is to provide a dental treatment tool suitable for shaving the surface of bone such as a tooth, collecting the scraped bone fragments, and moving them to a desired location.
請求項1の発明は、振動体に着脱自在に連結され、該振動体によって振動される歯科治療用チップであって、該チップの先端側は、該チップの延長軸に直角の断面形状が弧状であることを特徴としたものである。 The invention according to claim 1 is a dental treatment tip that is detachably connected to the vibrator and is vibrated by the vibrator, and the tip side of the tip has an arcuate cross section perpendicular to the extension axis of the tip. It is characterized by being.
請求項2の発明は、請求項1の発明において、前記チップは先端部において内側に向って傾斜していることを特徴としたものである。 The invention of claim 2 is characterized in that, in the invention of claim 1, the tip is inclined inward at the tip portion.
請求項3の発明は、請求項1又は2の発明において、前記チップは前記弧状の径が先端部側で徐々に小さくなって終端していることを特徴としたものである。 The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the tip ends with the arcuate diameter gradually becoming smaller on the tip side.
本発明によると、振動体に着脱自在に連結され、該振動体によって振動される歯科治療用チップであって、該チップの先端側は、該チップの延長軸に直角の断面形状が弧状で、この弧状の両側部より歯に効果的に振動を与えることができるので、歯を掴むことなく抜歯することができ、特に、埋没歯や折れた歯根等、従来の鉗子では掴むことが困難な歯牙を容易に抜歯することができ、更には、歯牙等骨の表面を削り、削った骨片をかき集め、所望の箇所へ移動させるのに好適な歯科治療具を提供することを目的としてなされたものである。 According to the present invention, a dental treatment chip that is detachably connected to a vibrating body and vibrated by the vibrating body, the tip side of the chip is arc-shaped in cross section perpendicular to the extension axis of the chip, Since the teeth can be effectively vibrated from both sides of the arc, teeth can be extracted without grasping the teeth, especially teeth that are difficult to grasp with conventional forceps, such as buried teeth or broken roots. It was made for the purpose of providing a dental treatment tool that can be easily extracted, and that is suitable for scraping the surface of bone such as a tooth, collecting the scraped bone pieces, and moving them to a desired location. It is.
図1は、本発明による歯科用チップの一実施例を説明するための分解斜視図で、図中、1は振動子(例えば、超音波振動子、エアー振動子、モータ振動子等、周知の任意所望の振動子)で、該振動子1の先端部には雌ねじ1aが形成されており、この雌ねじ1aに、本発明による歯科用チップ10の雄ねじ部10aが着脱自在に連結されるようになっている。10bは、チップ10を振動子1に螺着する時に用いるレンチを係合させるレンチ係合部で、該レンチ係合部10bにレンチを係合させ、該レンチにてチップ10を回転して該チップ10のねじ部10aを振動子1のねじ部1aに締め付けて固定する。
FIG. 1 is an exploded perspective view for explaining an embodiment of a dental chip according to the present invention. In FIG. 1, reference numeral 1 denotes a known vibrator such as an ultrasonic vibrator, an air vibrator, or a motor vibrator. An arbitrary desired vibrator) is provided with a female screw 1a at the tip of the vibrator 1, and the
本発明によるチップ10は、上述のように、振動子1に連結されて使用されるものであるが、振動伝達部10cは、その先端側10dにおいて、図1(B)(図1(A)のB−B断面図)に示すように、軸心(延長方向)Pに直角の断面が弧状に形成されており、この弧状の両側部10eが歯牙等の骨20に当接するようになっており、この両側部10eにおいて、歯牙を動揺させ、或いは、骨を切削する。また、先端部10d’は、好ましくは、図1(A)に破線にて示すように、内側に向って丸みをもって湾曲しており、歯を抜くときに、この先端部10d’を歯に引っかけて抜くことにより、より効果的に抜歯することができ、或いは、歯牙を切削し、切削した骨片をかき集め、移動させるのに効果的に使用することができる。
The
図2は、図1に示したチップ10の弧状部10dを斜め下から見た図で、この弧状部10dの最先端10fは、図2(B)に示すように、両側部10e,10eを平行に保ったままの状態で外面側にR(丸み)を持たせて終端してもよいが、図2(C)に示すように、弧状が徐々に小さくなるように、つまり、先端10fが丸みをもって尖出して終端するようにしてもよく、このようにすると、先端部を歯と歯肉の間に入れやすく、また、切削した骨粉をかき集めやすくなる。
FIG. 2 is a view of the arc-
図3は、本発明による歯科用チップの使用状態の一例を示す図で、図中、20は歯、21は歯肉、10dは本発明によるチップ10の先端側で、該チップ10の先端10d’は丸みをもって歯20側に湾曲されており(図1(A)の破線)参照、これによって、歯20と歯肉21の間に効果的に挿入することができ、更には、先端部の弧状の径を徐々に小さくして終端するようにしておくと(図2(C)の10f)、中央部の尖ったところから徐々に挿入することができるので、より効果に、歯20に沿って挿入することができ、また、埋没した歯や折れた歯根を掘り起こして抜くのに効果的である。更には、両側部及び先端部にて歯牙を切削し、切削した歯骨粉をかき集め、上方にかき出すのに使用して好適である。
