Description
本發明,係關於拔牙輔助用具。The present invention relates to tooth extraction aids.
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)。In the case of tooth extraction in dental treatment, generally speaking, between the tooth and the alveolar bone, the tooth extraction pole is inserted into the periodontal ligament around the root of the tooth to dislocate the tooth, and then the dental extraction forceps are used Teeth are caught 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 pressed in by mistake while prying the tooth with the extraction stile, it may cause nerve damage or blood vessel damage, which may lead to increased bleeding, or the alveolar bone may be sunken.
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。握持把手部,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)。 [先前技術文獻] [專利文獻] Therefore, the inventors of the present invention propose a tooth extraction aid that can perform tooth extraction more safely and easily (for example, refer to Patent Document 3). The tooth extraction aid is provided with a screw part screwed into the teeth and a handle part, and an anti-slip part is formed on the handle part. Hold the handle part, screw the screw part into the hole in the center of the tooth, and after the screw part firmly bites into the tooth, apply force to the handle part to pull the tooth out of the gum. If there is a torsional force acting on the root of the tooth, the tooth will float from the alveolar bone more easily, so the tooth can be extracted easily. Therefore, it is not necessary to use a tooth extraction bar during tooth extraction, and the force of tooth extraction will only be applied to the tooth to be extracted, so it is rarely affected by or affects adjacent teeth, so it is safe (for example, Refer to Patent Document 4).

[發明所欲解決之問題][Problem to be solved by the invention]
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 portion must surely bite into the tooth, it is inevitable that a force in a twisting direction will be applied to the tooth at this time. Even so, when screwing the screw part into the hole in the center of the tooth by the handle part and firmly biting into the tooth for fixation, it is better not to apply too much force in the direction of twisting to the tooth.
