Description

Periodontal toothbrush

The present invention relates to a kind of toothbrush.

At age more than 30 years old among the people, the gum periodontal disease is the one of the main reasons of infringement tooth.In the U.S. with there is the people more than 1,000,000 all to endure the worry that periodontal disease is brought to the fullest extent all over the world.The main cause that causes periodontosis is the formation of spot on tooth and gathers.Spot generally be viscosity material, it invests dental surface particularly on the gum line.When spot gathered, owing to be the deposit of insoluble calcium salt, this stickum became hard.These hard material are gathered under gum and are developed to teeth roots, and destroy being connected of a tooth fiber and a support bone.Gingival tissues can be infected, and makes odontoseisis, has at last be taken out.This disease is called as pyorrhea or periodontitis.

For reducing the generation of periodontitis or pyorrhea, people have done various effort.By dailyly brushing teeth, use dental floss, wash tooth with a press water by nozzle, and scale removal that the expert removes spot and calculus attempts obtaining better teeth caring to allow occupation clean one's teeth at interval in a period of time.

In various teeth caring methods, the best tooth method of protecting is to use by the toothbrush of the bristle of certain orientation arrangement cluster arrangement and brushes teeth with cleaning teeth.Below several pieces of patent disclosures the structure of attempting in this respect: 1,059,426; 1,657,450; 2,042,239; 2,797,424; 3,007,491.

The length of all bristles of traditional toothbrush is identical; just can not arrive between the teeth space that different depth is arranged in the mouth in different places in the mouth; for giving tooth and their support gingiva tissue, reaching the protection that underlying bone structure is given maximum; must from teeth space, remove deblurring and food fragment; therefore prevent gathering and hardening of spot calculus; because conventional toothbrush can not brush interdental space effectively, caused gingiva tissue undermined and bleed.Spot will gather hardening and expansion to teeth roots below gingiva tissue, therefore gingiva tissue be peeled off out from the support bone middle part and the oral pocket that adhere to, and these oral pockets are understood infected and tooth can become flexible the periodontal situation that causes being commonly referred to pyorrhea.Existing toothbrush does not comprise such structure, promptly can provide desired and remove the deblurring reliability from zone between teeth space.

An object of the present invention is to provide a kind of toothbrush, it can remove deblurring effectively in the interval of tooth that traditional toothbrush is difficult for entering, and has prevented that therefore spot from gathering the grievous injury to gum and the support bone structure below it that causes.Toothbrush of the present invention comprises a brushing cluster arrangement of finishing the uniqueness of this function.

Another object of the present invention provides a kind of toothbrush, and wherein brushing clusters arrangement will be removed deblurring from the zone that spot may gather effectively.These zones are the tongue bent face of nipper down and premolar teeth and the molar tooth surface in the lower jaw.In the upper jaw, gathering of spot be removed and be prevented to toothbrush will on the interior cheek of premolar teeth and molar and tongue bent face.

Another object of the present invention provides a kind of toothbrush, and it is in the brushing cluster profile and arrange to be configured and can make things convenient for and clean the established dental surface of institute's spottiness effectively.Toothbrush of the present invention can not only be from removing deblurring and food debris between teeth space, and can mildly massage gum and cleaning and scrub tooth, therefore prevented gingivitis or periodontitis significantly, and created the oral environment of a health.

The present invention also has another purpose to provide a kind of toothbrush, it have cluster at handle away from the bristle on brush one end.This attached brush will easily enter owing to oral pocket greatly or tooth dislocation or rotate and needs additional independent or the special zone of being noted, for from the gum gap area that is difficult for entering, removing food debris and spot and preventing the generation of periodontal disease, this brush is relatively little, and the annex of an additional effect is provided.

For achieving the above object, the invention provides a kind of periodontal toothbrush, comprise a handle; One is supported on handle one end and the brush that extends to form on handle one end; Described brush comprises many bunches of bristles, each bunch bristle is in horizontal expansion, vertically be spaced, described bristle also is arranged to longitudinal extension, laterally is spaced, the horizontal expansion line of bristles respectively has different length, it is characterized in that, each bunch bristle of horizontal expansion row begins from described handle farthest to arrange by strange, even number, the length that all odd number horizontal expansion rows go up each bunch bristle is identical, each bunch bristle lengths of even number horizontal expansion row is shorter than odd number row brush tuft, and arranging the beginning from short bristles away from handle, the bristle lengths of each even rows increases gradually.

Different with existing toothbrush, the present invention is by design of anatomy principle and structure, and toothbrush of the present invention can enter and effectively clean those teeth space gaps that is difficult for entering, and has therefore reduced the formation of spot and calculus and tooth has been kept clean and healthy state.

All these purposes and advantage will be below to Tooth-brush structure and operation further specify with claim in simultaneously with reference to seeing clearlyer as the accompanying drawing of an invention part, wherein same numeral is represented same section.
