Definitions
- the present invention relates generally to a toothbrush. More particularly, the present invention relates to a toothbrush which has pairs of bristles configured in a bundle, each of the pairs of bristles being composed of a first bristle having a fine end portion and a second bristle having a flat end portion, thereby more efficiently removing food remnants that are stuck between teeth or remain on the surfaces of teeth, and efficiently removing food remnants stuck between teeth and dental braces even when the dental braces are installed on the teeth.
- a toothbrush which is used to clean teeth, can keep the teeth clean by removing food remnants which remain on the surfaces of the teeth or are stuck between the teeth due to food intake.
- a normal toothbrush includes a head in which a bundle of toothbrush bristles are embedded to form columns, and a handle, wherein end portions of the plurality of toothbrush bristles are formed to have flat and straight shapes.
- the orthodontic treatment is meant to create a healthy oral tissue and a beautiful facial appearance by simply correcting crooked teeth and correcting various skeletal inconsistencies that may occur during a growth process so that the teeth can function normally.
- Orthodontic diagnosis includes the process of establishing a treatment plan suitable for each individual by analyzing patient's problems by using first medical examination, X-ray imaging, a dental model, facial photographs, and intraoral photographs.
- Orthodontic treatment includes the process of controlling the movement of teeth and the growth of the jawbone by using a fixed orthodontic appliance, a removable orthodontic appliance, or an external device.
- the present invention has been proposed to solve the above-mentioned problems, and is intended to propose a toothbrush which has a bundle of pair of bristles configured in a bundle, each of the pairs of bristles being composed of a first bristle having a fine end portion and a second bristle having a flat end portion, thereby more efficiently removing food remnants that remain between teeth and on the surfaces of teeth so that careful tooth brushing is performed.
- the present invention is intended to provide a toothbrush having bristles, each of the toothbrush bristles being divided into an outer bristle and an inner bristle, thereby allowing careful tooth brushing to be performed between dental braces and teeth.
- the present invention is intended to provide a toothbrush, which has separate molar bristles provided on a corner portion of a surface of a head thereof, thereby more efficiently removing food remnants remaining on a molar.
- the present invention is intended to provide a toothbrush, wherein embossments are provided on multiple toothbrush bristles, thereby more effectively removing food remnants remaining the surfaces of teeth, and providing resilience to the toothbrush due to elasticity.
- the present invention is intended to provide a toothbrush, wherein the bundle of toothbrush bristles is formed in longitudinal direction of the head only in two columns at the middle of a surface of the head so that the toothbrush can be usefully utilized as a toothbrush for a person who has an implant.
- the present invention provides a toothbrush composed of a head and a handle connected to an end of the head, the toothbrush including: toothbrush bristles configured in a bundle, each of the toothbrush bristles composed of a first bristle having a fine end portion corresponding to space between teeth, and a second bristle provided at an inner side of the first bristle and having a flat end portion corresponding to a surface of tooth, the toothbrush bristles being arranged in multiple columns on a surface of the head.
- each of the toothbrush bristles may be configured by being divided into an outer bristle configured as a pair of a first bristle and a second bristle and embedded in an outer portion of the surface of the head, and an inner bristle configured as a pair of a first bristle and a second bristle and embedded in the head to be arranged at an inner side of the outer bristle.
- outer bristle and the inner bristle may be configured to have different lengths so as to be arranged to have a V-shaped cross section.
- the toothbrush may further include: molar bristles embedded in multiple columns in an outer portion of the surface of the head, each of the molar bristles having multiple unit bristles configured in a bundle and inclined downward inward in end portions thereof.
- the molar bristle may be a regular bristle or a fine bristle, and each of the toothbrush bristles is a fine bristle.
- the molar bristle may be configured in the bundle on a corner portion of the surface of the head, and provided in the multiple columns.
- the first bristle may be configured to taper in a direction of an outer end portion thereof.
- a length of the second bristle having the flat end portion may be configured to be shorter than a length of the first bristle.
- an embossment may be provided on each of outer circumferential surfaces of the first bristle and the second bristle.
- an embossment may be provided on an outer circumferential surface of the molar bristle.
- each of the unit bristles of the molar bristle may have a flat end portion provided on an upper end thereof.
- the bundle of the toothbrush bristles composed of the pair of the first and second bristles and the bundle of the molar bristles may be configured in longitudinal directions of the head only in two columns at a middle of the surface of the head.
- pairs of bristles are configured in a bundle, each of which is composed of the first bristle having the fine end portion and the second bristle having the flat end portion, thereby more efficiently removing food remnants that remain between teeth and on the surfaces of teeth.
- end portions of the outer bristle and the inner bristle divided to be embedded to be perpendicular to an upper surface of the head are arranged to have a V-shaped cross section, and allow careful tooth brushing to be performed between dental braces and the teeth, thereby minimizing discomfort such as enamel wear, gum injury, and bristle loss.
- separate molar bristles each of which has multiple unit bristles inclined downward inward in end portions thereof, are provided on a corner portion of a surface of the head of a toothbrush, thereby reliably removing food remnants remaining on a molar.
- embossments are provided on multiple toothbrush bristles, thereby further removing food remnants remaining the surfaces of teeth, providing resilience due to elasticity, and increasing the amount of foam produced during the use of toothpaste to maintain freshness in the mouth due to spaces between the embossments.
- the bundle of the toothbrush bristles is formed in longitudinal directions of the head only in two columns at the middle of a surface of the head, thereby allowing the toothbrush to be usefully utilized as a toothbrush for a person who has an implant.
- the terms are used only for the purpose of distinguishing one component from other components.
- the first component may be referred to as the second component, and similarly, the second component may also be referred to as the first component.

- FIG. 6 is a top plan view of the toothbrush according to a fourth embodiment of the present invention, and is substantially the same as the example of FIG. 5 except for a toothbrush bristle 500 for an implant for a person who has an implant.
- a bundle of the toothbrush bristles 500 for an implant each of the toothbrush bristles having a pair of the first and second bristle, is configured to be formed in longitudinal direction of the head only in two columns at the middle of the surface of the head 10 so as to be used as a toothbrush only for a person who has an implant.
- the molar bristles 400 are provided in a bundle on the corner portion of the surface of the head 10, and in multiple columns.
- the bundle of the molar bristles 400 may also be formed in two columns in the longitudinal directions of the head alongside the bundle of the toothbrush bristles 500 at the middle of the head 10.
- the present invention provides the toothbrush which has pairs of bristles configured in a bundle, each of the pair of bristles being composed of the first bristle having the fine end portion and the second bristle having the flat end portion, thereby more efficiently removing all food remnants which remain between teeth and on the surfaces of teeth, and efficiently removing food remnants stuck between teeth and dental braces even when the dental braces are installed on the teeth. Accordingly, the toothbrush of the present invention will be usefully used in a toothbrush area.
