Description
本發明,係關於拔牙輔助用具。 The present invention relates to an auxiliary tool for tooth extraction.
於牙科治療中進行拔牙的情形,一般而言,係在牙齒與牙槽骨之間,將拔牙梃插入位於牙根的周圍之牙周膜的部位而使牙齒脫臼,再使用牙科用的拔牙鉗夾住牙齒並拔取(例如,參照專利文獻1及2)。
Tooth extraction during dental treatment is generally performed between the tooth and the alveolar bone. A tooth extraction rod is inserted into the periodontal ligament around the tooth root to dislocate the tooth, and then dental tooth extraction pliers are used. The tooth is held and extracted (for example, refer to
然而,若在藉由拔牙梃撬動牙齒之際發生誤將牙齒壓入之情事,會有因此導致神經損傷或血管破損而令出血增多,又或使牙槽骨凹陷之情形。 However, if the tooth is accidentally pushed in when levering the tooth through extraction, it may cause nerve damage or blood vessel damage, increase bleeding, or cause the alveolar bone to be dented.
因此,本發明之發明者,係提案有一種能夠更安全且輕易地進行拔牙之拔牙輔助用具(例如,參照專利文獻3)。該拔牙輔助用具,係具備螺入牙齒內的螺絲部以及把手部,並於該把手部形成有止滑部。把持把手部,再將螺絲部螺入牙齒的中心部的孔,在螺絲部確實咬入牙齒之後,對於把手部施力而將牙齒從牙齦拔出。若對於牙根作用有扭轉力,則牙齒會較容易從牙槽骨浮起,故能夠輕易地進行拔牙。因此,在拔牙時不須使用拔牙梃,且拔牙的力僅會施加於欲進行拔牙的牙齒,故鮮少受相鄰的牙 齒影響,或對相鄰的牙齒造成影響,故係安全(例如,參照專利文獻4)。 Therefore, the inventor of the present invention proposes a tooth extraction auxiliary tool that can perform tooth extraction more safely and easily (for example, see Patent Document 3). The tooth extraction auxiliary tool has a screw part screwed into the tooth and a handle part, and an anti-slip part is formed on the handle part. Hold the handle and screw the screw into the hole in the center of the tooth. After the screw is firmly bitten into the tooth, force is applied to the handle to pull the tooth out of the gums. If there is a torsional force acting on the root of the tooth, the tooth will be more easily lifted from the alveolar bone, so the tooth can be easily extracted. Therefore, there is no need to use an extraction frame during tooth extraction, and the extraction force will only be exerted on the tooth to be extracted, so there is little impact on the adjacent teeth. It is safe because it does not affect the teeth or affects adjacent teeth (for example, refer to Patent Document 4).

然而,因必須使螺絲部確實咬入牙齒,故無可避免地會於此時對牙齒施加扭轉方向的力。即便如此,在藉由把手部將螺絲部螺入牙齒的中心部的孔而確實咬入牙齒以進行固定之際,係不致對於牙齒施加過多扭轉方向的力為佳。 However, since the screw part must be firmly bitten into the teeth, a twisting force is inevitably exerted on the teeth at this time. Even so, when screwing the screw part into the hole in the center of the tooth with the handle part and firmly biting into the tooth for fixation, it is preferable not to exert too much force in the twisting direction on the tooth.
因此,本發明係以提供一種拔牙輔助用具等為目的,其係能夠減輕施加於欲拔取的牙齒、該部位的牙槽骨及/或相鄰的牙齒的負擔。 Therefore, the present invention aims to provide a tooth extraction auxiliary tool, etc., which can reduce the load placed on the tooth to be extracted, the alveolar bone of the site, and/or the adjacent teeth.

(第1實施形態) (構成) (First Embodiment) (composition)
圖1所示之作為本發明之第1實施形態之拔牙輔助用具1,係具備第1輔助基體11、第2輔助基體12、連結第1輔助基體11及第2輔助基體12的連結部10。拔牙輔助用具1的素材雖可任意選擇,然而例如能夠以鎳-鈦合金形成。A tooth extraction
第1輔助基體11,係形成為大致球形。第1輔助基體11的尺寸,係如圖1所示,係設計為能夠對於凹部X0插入的尺寸,該凹部X0係貫穿設置於牙根埋入在牙齦X1的狀態之牙齒X2的牙冠。第1輔助基體11的形狀除了大致球形以外,亦可為大致橢圓球形、大致半球形、大致立方體形、大致長方體形、大致圓柱形、大致角柱形、大致圓錐形、大致角錐形、大致圓錐台形或大致角錐台形,或者,組合該等形狀之各種形狀。此係於其他實施形態亦相同。The first
第2輔助基體12,係形成為比第1輔助基體11更大徑之大致圓柱狀或大致圓板狀。第2輔助基體12的形狀除了大致圓柱狀或大致圓板狀以外,亦可為大致正多角形板狀、大致球形、大致橢圓球形、大致半球形、大致立方體形、大致長方體形、大致圓柱形、大致角柱形、大致圓錐形、大致角錐形、大致圓錐台形或大致角錐台形,或者,組合該等形狀之各種形狀。此係於其他實施形態亦相同。The second
於第2輔助基體12的側面,以往軸線方向延伸的線狀往徑方向外側突出之複數個凸條部120,以於周方向分離配置的方式形成。取代複數個凸條部120,亦可於第2輔助基體12的側面,以往軸線方向延伸的線狀往徑方向內側凹陷之複數個溝部或凹條部,以於周方向分離配置的方式形成。取代複數個凸條部120,亦可於第2輔助基體12的側面,往徑方向外側突出之複數個大致半球狀的凸部以分散配置的方式形成等,形成各種凹凸構造。On the side surface of the second
連結部10,係形成為比第1輔助基體11更小徑之大致圓柱狀或桿狀。連結部10,係以其中心軸線對於第1輔助基體11的中心軸線一致或大致一致的方式,對於該第1輔助基體11在其中一端部以一體地或能夠卸除的方式固定。連結部10,係以其中心軸線對於第2輔助基體12的中心軸線一致或大致一致的方式,對於該第2輔助基體12在另一端部以一體地或能夠卸除的方式固定。The connecting
連結部10之形狀,除了大致圓柱狀以外,亦可為彎曲形狀、螺旋形狀等之各種形狀。連結部10,係亦可以其中心軸線對於第1輔助基體11的中心軸線傾斜的方式,對於該第1輔助基體11在其中一端部固定。連結部10,係亦可以其中心軸線對於第2輔助基體12的中心軸線傾斜的方式,對於該第2輔助基體12在另一端部固定。此係於其他實施形態亦相同。The shape of the connecting

Next, a method of using the tooth extraction
作為熱熔接著劑M,有鑑於治療時間的限制,係以能夠盡快固化者為佳。一般而言,係能夠使用APOA(Amorphous Poly Alpha Olefin,非晶質聚α烯烴)樹脂或EVA(Ethylene Vinyl Acetate,乙烯/乙酸乙烯酯)樹脂等。為了加快熱熔接著劑M的固化,係有強制地噴吹空氣或水而藉此冷卻熱熔接著劑M般之治療方法。又,與其他接著劑以黏液狀收納於軟管中而有裝卸蓋體之繁瑣性之情事相比,熱熔接著劑M只要事先安裝於熱熔注入具則隨時能夠直接使用,故適合用於拔牙治療。在熱熔注入具形似手槍的情形,係容易對準目的之牙齒X2。As a hot melt adhesive M, in view of the limitation of treatment time, it is better to use one that can be cured as quickly as possible. Generally speaking, APOA (Amorphous Poly Alpha Olefin, amorphous polyalpha olefin) resin or EVA (Ethylene Vinyl Acetate, ethylene/vinyl acetate) resin, etc. can be used. In order to speed up the solidification of the hot melt adhesive M, there is a treatment method such as forcibly blowing air or water to cool the hot melt adhesive M. In addition, compared with other adhesives that are stored in the tube in a viscous state and require tedious installation and removal of the cover, the hot-melt adhesive M can be used directly at any time as long as it is installed in the hot-melt injection tool in advance, so it is suitable for Tooth extraction treatment. In the case where the hot melt injection tool is shaped like a pistol, it is easy to aim at the target tooth X2.
並且,操作者以指尖把持第2輔助基體12,再一邊對於第2輔助基體12施加扭轉的力,一邊使第2輔助基體12往遠離牙齦X1的方向移動,而藉此將牙齒X2從牙齦X1拔出(圖2/STEP3)。Furthermore, the operator holds the second
因於第2輔助基體12的側面形成有凸條部13,故在以拇指與食指及/或中指把持第2輔助基體12,再對於其中心軸線施加旋轉力或扭轉力之際,能夠抑制唾液等導致該手指及第2輔助基體12滑動之情事。在因施加於牙齒X2的扭轉導致牙齒X2從牙齦X1浮起之際,藉由手指強力把持或藉由拔牙鉗的顎部夾住第2輔助基體12的狀態下,將牙齒X2從牙齦X1拔出(拔牙)。Since the convex portion 13 is formed on the side surface of the second

第2輔助基體12,係形成為與第1輔助基體11的底部大致同徑之大致圓柱狀或大致圓板狀。於第2輔助基體12的側面,亦可與第1實施形態相同,形成有用以止滑之凸條部、凹條部及/或凸部。The second

於圖4,係表示有與圖3所示之拔牙輔助用具1一起構成拔牙用具套組的拔牙用具2。如圖4所示,拔牙用具2,係具備:第1基體21,在俯視下為細長的平板狀;以及第2基體22,係設於第1基體21的長度方向的其中一端部,在俯視下為大致長圓形或大致橢圓形。FIG. 4 shows a
於第1基體21的另一端部,形成有用以作為穿繩部等之孔210。第2基體22,雖整體形成為如湯匙般的凸曲面狀,然而底部220係形成為平坦或大致平坦(意指第2基體22之曲率比其周圍部分更小)。於第2基體22的前端部,形成有用以將該前端部分割為雙叉般之卡合缺口部221。於第2基體22的後端部,形成有:卡合孔222,係藉由比拔牙輔助用具1的第2輔助基體12更大徑之大致圓形的孔,以及連續於該孔的後方之寬度比第2輔助基體12的直徑更小之大致矩形的孔構成。卡合缺口部221雖到達第2基體22的緣部,然而卡合孔222並未到達第2基體22的緣部(與第1基體21的連續部)。於第2基體22的前端部,亦可形成有與卡合孔222相同的卡合孔以取代卡合缺口部221。The
(使用方法)
針對前述構成的拔牙輔助用具1,以及藉由拔牙輔助用具1及拔牙用具2構成之拔牙用具套組的使用方法進行說明。首先,藉由切削器具於牙齒X2的牙冠形成第1輔助基體11能夠進入的程度之尺寸的凹部X0(參照圖1),並如圖5所示,將第1輔助基體11插入至該凹部X0(參照圖2/STEP1)。
(Instructions)
The method of using the tooth extraction
接著,對於插入有第1輔助基體11的狀態之凹部X0,使用熱熔注入具注入溶解的熱熔接著劑M,並使該熱熔接著劑M固化。藉此,如圖5所示,藉由固化的熱熔接著劑M將拔牙輔助用具1固定於牙齒X2(參照圖2/STEP2)。Next, the melted hot-melt adhesive M is injected into the recessed portion X0 in which the first
並且,把持拔牙用具2的第1基體21之操作者,係一邊以底部220尋找相鄰於牙齒X2(就第2基體22對於口腔的插入方向而言)的齒列的上表面部分,一邊使第2基體22的卡合孔222勾掛於拔牙輔助用具1的第2輔助基體12。並且,使拔牙用具2往遠離牙齦X1的方向移動,而藉此將該牙齒X2與拔牙輔助用具1一起從牙齦X1拔出(參照圖2/STEP3)。Furthermore, the operator holding the
藉由大致湯匙形的第2基體22之平坦或大致平坦的底部220,不僅是齒列的上表面部分,操作者亦能夠尋找該齒列的角落。因能夠尋找牙齒的角落部分及齒列的階差部分,故該操作者能夠對應患者難以張口的狀況及/或口的形狀,以及操作者的姿勢、患者的牙齒排列及/或咬合等之個別狀況。Through the flat or substantially
把持拔牙用具2的第1基體21之操作者,係亦可一邊以第2基體22的底部220尋找相鄰於牙齒X2(就第2基體22對於口腔的插入方向之相反方向而言)的齒列的上表面部分,一邊使第2基體22的前端部的卡合缺口部221勾掛於拔牙輔助用具1的第2輔助基體12。並且,亦可按壓拔牙用具2的第1基體21而將牙齒X2與拔牙輔助用具1一起從牙齦X1拔出。The operator holding the
如此,能夠減輕相鄰於牙齒X2的牙齒之影響,而能夠安全穩定且輕易地進行拔牙,故能夠減輕患者的負擔及操作者進行拔牙作業的負擔。因第2基體22的形狀係俯視為大致長圓形,故在使第2基體22進入患者的口腔內之際抵抗感較低,故就此而言亦能夠安心。In this way, the influence of the teeth adjacent to the tooth X2 can be reduced, and the tooth can be extracted safely, stably and easily. Therefore, the burden on the patient and the operator in the tooth extraction operation can be reduced. Since the shape of the
本實施形態之拔牙輔助用具1,與第1實施形態相同,操作者不使用類似於湯匙形狀的拔牙用具2,而是以指尖一邊把持第2輔助基體12一邊將牙齒X2從牙齦X1拔出亦可。拔牙用具2與第1實施形態之輔助用具1(參照圖1)組合使用亦可。The tooth extraction

第2輔助基體12,係形成為比第1輔助基體11更大徑之大致圓環板狀。於第2輔助基體12的內側面,形成有母螺紋部。與第1實施形態相同,於第2輔助基體12的內側面,亦可形成有用以止滑之凸條部、凹條部及/或凸部。The second
連結部10,係形成為比第1輔助基體11更小徑之大致圓柱狀或桿狀。於連結部10的側面,形成有螺合於第2輔助基體12的母螺紋部之公螺紋部100。連結部10,係以其中心軸線對於第1輔助基體11的中心軸線一致或大致一致的方式,對於該第1輔助基體11在其中一端部以一體地或能夠卸除的方式固定。連結部10,係以其中心軸線對於第2輔助基體12的中心軸線一致或大致一致的方式,對於該第2輔助基體12螺合。The connecting
(使用方法)
接著,針對前述構成的拔牙輔助用具1的使用方法進行說明。首先,如圖7所示,藉由切削器具於牙齒X2的牙冠形成第1輔助基體11能夠進入的程度之尺寸的凹部X0,並將第1輔助基體11插入至該凹部X0(參照圖2/STEP1)。接著,旋轉第2輔助基體12,使第1輔助基體11與第2輔助基體12的間隔擴大。此係為了使第2輔助基體12在熱熔接著劑注入牙齒X2的凹部X0之際不致造成阻礙。
(Instructions)
Next, a method of using the tooth extraction
接著,如圖6所示,對於插入有第1輔助基體11的狀態之凹部X0,使用熱熔注入具注入溶解的熱熔接著劑M,並使該熱熔接著劑M固化(參照圖2/STEP2)。藉此,藉由固化的熱熔接著劑M將拔牙輔助用具1固定於牙齒X2。Next, as shown in FIG. 6 , a hot melt injection tool is used to inject the dissolved hot melt adhesive M into the recessed portion X0 in which the first
接著,將第2輔助基體12往與先前相反的方向旋轉,而使第1輔助基體11與第2輔助基體12的間隔縮小。並且,把持如圖4所示般之構成的拔牙用具2的第1基體21之操作者,係一邊以底部220尋找相鄰於牙齒X2(就第2基體22對於口腔的插入方向而言)的齒列的上表面部分,一邊使第2基體22的卡合孔222勾掛於拔牙輔助用具1的第2輔助基體12。並且,使拔牙用具2往遠離牙齦X1的方向移動,而藉此將該牙齒X2與拔牙輔助用具1一起從牙齦X1拔出(參照圖2/STEP3)。Next, the second
於本實施形態,係藉由形成於大致圓柱狀之連結部10的側面之公螺紋部100,以及形成於大致圓環狀之第2輔助基體12的內側面之螺合於該公螺紋部100之母螺紋部,構成用以調節第1輔助基體11與第2輔助基體12的間隔之間隔調節機構。除此之外,例如,亦可將間隔調節機構構成為使連結部10為滑移式而使長度可變且能夠固定之構造。
