Abstract

Provided is a toothbrush having a flocked portion having a high dental plaque removing effect in which the tip of a brush reaches a dent of a tooth without using any other cleaning aids and is difficult to get between teeth.
In a hand toothbrush, a brush 4 is cut so that a flocked portion 2 becomes an outer line 5. In the longitudinal envelope, the highest point X is set at a position two thirds of the length of the flocked portion in the longitudinal direction from the tip, the tip 6 is lower, the rear end 7 is slightly higher than the tip, and the connecting line is a gentle asymmetric arc. Make. The lateral outline is a rounded curve that is symmetrical with respect to both sides, with the highest point X being the center of the width. This shape secures a brushed surface that takes into account the toothbrush entry angle and working space while at the same time increasing the elasticity of the brush. Due to the elasticity of the brush, the flocked portion has a force to adapt to or touch the tooth shape and enhance the plaque removal effect.

Description

  The present invention relates to the shape of a flocked portion of a toothbrush.

A hand toothbrush in which a plurality of bundles of brushes are arranged in the longitudinal direction of the flocked portion is liable to fall down due to a load during use, and lacks dental dents and plaque removal power between teeth. Other cleaning aids are also used.

JP 2006-305289 A

In general, a hand toothbrush that is widely used has a brush that falls or separates during use, and lacks the ability to remove plaque and interdental plaque. The present invention seeks to solve the problem with a toothbrush having a flocked portion with a high plaque removing effect that can be applied to various shapes of teeth including indentations and interdental teeth without using other cleaning aids.

The present invention starts from the fact that unfinished polish was pointed out every time during the dentist examination. Other auxiliary cleaning devices were difficult to habituate in effort and time. We focused on the characteristics of brushes in relation to plaque and toothbrushes attached to complex shapes.

The brush has a bending property. The following is quoted because it has elasticity and bends softly without breaking. Long brushes are flexible and suitable for sweeping the upper side over a wide area, and short brushes are elastic and adapt to narrow spaces such as indentations and grooves. In order to enable effective tooth brushing, it was considered that a short brush with a narrow bending width and elasticity was suitable. While the length of a general toothbrush brush is 10 to 12 mm, in the present invention example, the highest point X is 9 mm, the front end 6 is 4 mm, and the rear end 7 is 6 mm.

Fig. 1 and Fig. 2 show the shape of the flocked portion with a brushing surface as wide as possible, taking into consideration the shape of the tooth and the toothbrush approach angle and working space. This shape is shortened toward the outline, but also serves to reinforce the brush around the highest point X where the brush is long.

In a hand toothbrush in which a plurality of bunch bundles are arranged in the longitudinal direction of the flocked portion, the brush is cut so that the flocked portion becomes the outer line of FIG. Fig. 1 shows the highest point X at a position two thirds of the length of the flocked portion in the longitudinal direction from the tip, the tip 6 is low and about half of the X point brush length, and the rear end 7 is the tip Slightly higher than 6 and 1.5 times the tip brush length, the connecting line Y1-Y2 forms a gentle asymmetric arc. FIG. 2 shows a line Z1-Z2 that has the highest point X at the center of the width and faces both sides 8 and is a symmetrically rounded curve.

In selecting a toothbrush, the brush quality should be normal or soft. If it is hard, it is elastic, but because of its length, it is difficult to reach the details, and it may damage the gums and oral skin. A flat or light curved object is suitable for the handle.

The toothbrush according to the present invention contacts and adapts to the shape of the tooth due to the elasticity of the brush. Or it can be bitten. By moving the toothbrush finely while changing the brushing surface and load, the plaque removal effect of the whole tooth is enhanced.

Among generally used toothbrushes, a toothbrush having a uniform brush length at the flocked portion and having three to five rows of flocks arranged by hand is manually cut into the shape of the present invention.

  In the shape of FIG. 1, the brush length is 4 mm at the front end and 6 mm at the rear end when the maximum point X is 9 mm, and the brush is cut at 5 mm at the front end and 7.5 mm at the rear end when the maximum point X is 10 mm. .

Apart from brushing with a short time required for customs, brushing is performed once a day for 8 to 10 minutes using the toothbrush of the present invention. Do not use other cleaning aids. The execution period was one year and three months from December 2016, during which a dentist checkup was received every six months. The places to be cleaned by dentists are limited and the time required is greatly reduced. Confirm the effect on the findings of the attending physician.

The main cleaning areas are introduced in Fig. 4. Each area is a line connecting the same symbols. On the ab surface, both sides are polished from the first premolar to the opposite first premolar. On the a side, the back tooth meshing portion and both side surfaces of the first premolar are polished. Polish between the grooves and teeth. On the c-plane, the roundness of the side is applied to the border with the gums and polished. Brush between your teeth with your flank. On the surface d, the back of the middle incisor of the frontmost tooth and the periphery of the second or third molar of the innermost tooth are polished so that the tip is raised.

Can be used for dental health management from children to adults. One of the necessary conditions is that the functions are integrated in daily necessities.
