JPH05168528A - Toothbrush having step in brush bristle implanted part - Google Patents

Abstract

PURPOSE:To completely remove a plaque and a deposit on a tooth surface and to simply clean parts between teeth, a molar tooth and an implanted artificial redressment tooth by providing a step by which the front part of implanted brush resinous bristle parts of a tooth brush is high and the rear part thereof is low. CONSTITUTION:In a front part, an implanted high brush resinous bristle part 1 is provided. In a rear part, an implanted low brush resinous bristle part 2 is provided. Further, an implanted hard resinous bristle part 4 and an implanted soft brush hair part 5 are provided. The brush resinous bristles employed in the part 1 are harder than those employed in the part 2. The ends of the part 1 are brought into contact with parts between teeth and the ends of the part 2 are brought into contact with the front surfaces of teeth. Thus, the high part and the low part of the implanted brush resinous bristle part are respectively uniformly brought into contact with parts between teeth and the front surfaces of teeth. Further, since the hardness is different in parts, when teeth are cleaned by the vertical movement of a toothbrush, a required force is applied to plaque between teeth as well as to the front surfaces of teeth even by cleaning the teeth with the same force. Thus, guns are not damaged.

とすると嘔吐感を感じるという欠点を有していた。2. Description of the Related Art A conventional toothbrush has a structure in which bristles having the same length are provided in the bristles. For this reason, the surface of the tooth can be polished relatively cleanly, but since the lengths of the flocked hairs are the same, it was necessary to strongly press the whole flocked hairs to remove plaque and the like between the teeth even when trying to brush the tooth spaces. However, even if it is possible to polish a part of the tooth surface by such an operation, the tips of the toothbrush are uniform and the tips of the teeth are not sufficiently inserted between the teeth, so that plaque etc. are sufficiently removed. Not only that, but it also had the drawback of damaging the gums if pressed hard and polished. Furthermore, especially when brushing the so-called posterior teeth (molars), because the flocked part is flat, the teeth in front of the teeth interfere and the roots of the posterior teeth do not reach and the brush cannot be sufficiently brushed. It had the drawback of feeling.

It was divided into parts and the like so that they could be used appropriately. However, even in this case, there is a problem in that the soft flocked part does not sufficiently polish the teeth, and the hard flocked part cannot prevent the gum damage. In addition, although there are some that have a small flocked portion in order to specially brush the back teeth and the spaces between teeth, when brushing the front teeth and the flat portion, it is inconvenient to replace with a toothbrush having a wide flocked portion. Furthermore, when polishing an implant denture, there is a slight gap between the denture and the gum, and if food residue or the like remains in the gap, it was almost impossible to remove it with a conventional toothbrush.

Further, the hair used for the flocked portion of 1 is harder than that of 2. In this example, a height of 1 is 9.
5mm, height of 2mm to 7mm, diameter of 1 hair transplant is 7
/ 1000 mm, the diameter of 2 is 5/1000 mm. The height of 1 may be 10 mm and the height of 2 may be 7 mm. In addition, the center of the short flocked part is 7/100
It is 0 mm and the peripheral side portion is 5/1000 mm. FIG. 2 is a plan view thereof. To prevent caries and alveolar pyorrhea, it is ideal to remove plaque as much as possible during tooth brushing. However, plaque that accumulates between the teeth and plaque that accumulates on the anterior surface of the tooth require different forces to be applied. That is, it is necessary to apply a strong force to the plaque between the teeth and a weaker force to the plaque on the front surface of the tooth. Otherwise, bleeding from the gums may be seen when a strong force is applied, and conversely plaque cannot be removed sufficiently when only a weak force is applied. Therefore, when the buccal teeth are brushed with the toothbrush provided with the step according to the present invention, the tips of the tall flocked portions 1 contact the teeth, and the tips of the short flocked portions 2 contact the front surface of the teeth. Become. For this reason, the high part and the low part of the bristle part are in contact with each other between the teeth and the front surface of the tooth on average, and in addition, since the hardness of the bristle part is different, when brushing the teeth by the vertical movement of the toothbrush, Even when brushing with the same force, the necessary force is applied to the plaque between the teeth and the front surface of the tooth, and the tooth can be brushed without damaging the gums. By sequentially moving the toothbrush laterally, the space between the teeth and the front surface of the teeth can be simultaneously and cleanly cleaned smoothly. When brushing the teeth on the lingual side, the toothbrush is mainly performed by moving the toothbrush in parallel, but like when brushing the buccal side,
Since the inter-tooth side of the tooth-shaped arch can be brushed with the hair-implanting portion 1 and at the same time the tooth can be carefully brushed with the hair-implanting portion 2, it is possible to completely remove plaque between the teeth on the lingual side.

力が平均的に加わる。Next, the case of brushing a molar using the toothbrush according to the present invention will be described. First, when brushing from the lingual side, the tall flocked portion 1 mainly comes into contact with the teeth, and the plaque on the lingual side, which has been difficult to remove in the past, can be easily removed. At the same time, the hair-implanted portion 2 comes into contact with the molar teeth and an average force is applied. Also, when brushing the molars from the upper surface, the tall flocked portion 1 is strongly pressed and polished. Further, when brushing from the buccal side, the toothbrush can be brushed back and forth to brush the molars and the interdental teeth evenly. At that time as well, the hair-implanted portion 2 comes into contact with the molars at the same time, and the force is applied evenly. In addition, there is a small cavity in the molars
Even if there is, since the toothbrush according to the present invention is provided with a step, the tall work bristle part 1 can enter the cavities to remove plaque, and at the same time, the bristle part 2 contacts the molar teeth,
Power is added on average.

接し、力が平均的に加わる。When the implant denture is brushed, a slight gap is generated between the implant denture and the gum, but since the toothbrush according to the present invention has a step at the bristle implant, the tip of the bristle implant enters the gap. It is possible to completely remove the food residue and the like that may accumulate in the gap. At the same time, the flocked part 2 comes into contact with the implant denture, and the force is applied on average.

歯の平坦部を磨くことができた。EFFECT OF THE INVENTION When the toothbrush according to the present invention is used for tooth brushing, the surface of the tooth can be brushed cleanly regardless of the method of brushing by vertically moving or moving in parallel, and when a local toothbrush is used. The force was more stably applied between the teeth and the plaque between the teeth could be removed almost completely. Also, even when brushing the teeth of a molar, which was difficult with conventional toothbrushes because the bristles are aligned, it is possible to brush on the buccal side, lingual side, and distal side by the tall bristles, resulting in plaque between teeth. Could be removed almost completely. Further, when brushing the implant denture, it was possible to remove food residue and the like that may accumulate in the slight gap between the denture and the gum, and to keep the implant denture clean. Furthermore, even when the teeth of a child are changed from milk teeth to permanent teeth, the space between the teeth can be kept particularly clean, and the permanent teeth can be prevented from becoming tooth decay. Furthermore, since the hardness of the flock at the central part and the peripheral part of the short flock is changed, the flat part of the tooth can be brushed without damaging the gums.
