Abstract

(57) [Summary] [Problem] Generally, commercially available toothbrushes have insufficient cleaning efficiency. SOLUTION: The shape of the tip of the toothbrush is closed by the interdental portion and the depression of the tooth.

Description

[Detailed description of the invention]

[0001]

[Problem to be solved by the invention]

 When brushing teeth, the shape of the brush tip of a conventional toothbrush first comes into contact with the convex portion of the tooth, and this becomes a resistance, making it difficult to clean the interdental portions and grooves.

[0002]

[Means for Solving the Problems]

 The shape of the tip of the toothbrush was pyramid-shaped so that it could well contact the interdental area and groove.

[0003]

[Effect of the invention]

 The efficiency of toothpaste cleaning is increased and tooth decay is reduced.

[Technical field to which the invention belongs]

 The present invention relates to a brush form of a toothbrush used for brushing teeth, and particularly considers a cleaning property of a molar occlusal surface.

[0002]

[Prior art]

 Most of conventional toothbrushes have a bundle of brushes bundled in a round shape, and the brush has been completed by the configuration of this bundle.

[0003]

[Problem to be solved by the invention]

 This had the following disadvantages. (B) Because the bundle of brushes was bundled in a round shape, it was difficult to form an ideal contact surface for making contact with the occlusal surface of the molar. (B) As a result of the market of toothbrushes having poor contact surfaces and a flat form, almost all first molars of all people have some kind of prosthesis. The present invention has been made to eliminate these disadvantages.

[0004]

[Means for Solving the Problems]

 In order to increase the efficiency of brushing the interdental area of the two teeth and the occlusal surface of the posterior teeth, four brushes with one isosceles triangle are arranged in a bundle when viewed from a plane. And a toothbrush shaped like a slope so that the height near the center of the brush tip is high.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described. The toothbrush of the present invention is configured morphologically in consideration of the cleanability of the interdental part of two teeth and the occlusal surface of the molar teeth. When viewed from a plane, one bundle unit of the brush is formed into an isosceles triangle, and this is formed into a quadrilateral by arranging four sides in parallel. Also, the tip of an isosceles triangular unit brush is formed in a slope so that the vicinity of the center of the square becomes higher. To ensure stability and the length of the dental arch for children and adults, place two or three square pillar brushes on the brush base.

[0006]

[Effect of the invention]

 Brush contact with the teeth is ensured and the contact area is increased, so that cleaning of the toothpaste is improved and tooth decay is reduced.
