Abstract
Disclosed is a dental care apparatus comprising at least one cleaning element of an extruded polymer, which contains in the polymer of the cleaning element at least in its area close to the surface a water and/or saliva-soluble additive with dental-medicinal and/or antibacterial effects in solid, fine dispersed form. Further disclosed is a method for producing cleaning elements of a polymer for said dental care apparatus, in which the molten polymer mass is mixed with the water and/or saliva-soluble additive having dental-medicinal and/or antibacterial effects in fine dispersed form and the mixture is extruded.
Description
The present invention relates to contain water soluble and/or saliva near surf zone and the toothbrush of polymer-extruded moulding bristle of the additive that protects the tooth effect and the method for preparing toothbrush bristle are arranged a kind of having at least at it.
Known toothbrush only has the mechanical cleaning action by rubbing between bristle and dental surface.In addition, they have massage effect to gums.
Some bristles have also been proposed, wherein polymer contains the metal ion of antibacterial action, for example with the solubility organic additive (the Derwent-Abstract 94-217929/26 of WO 94/13879 A1) of forms of zeolite (the Derwent-Abstract 91-004868/01 of JP02-283312A) or anti-microbial effect.
The objective of the invention is in order to expand the known toothbrushes sphere of action.
According to the present invention, this purpose can be by following solution: the solid inorganic fluorine compounds that add fine dispersion in polymer are as additive, and it isolates fluorine ion under the effect of water and/or saliva.
In liquid and ointment type toothpaste, use the additive of the fluorine compounds form of protecting the tooth effect to be familiar with, increase solid effect with the tooth that utilizes fluorine compounds by everybody.This effect is based on this fact, and people's dental enamel has the fluoride of relative higher concentration in outermost layer, and fluoride concentration descends rapidly in the deep layer of tooth.Usually be not enough to keep the stable of content of fluoride in the dental enamel by food and the fluoride amount that provides of drinking-water.And content of fluoride is conclusive to the ability of tooth opposing bacterium and acidic materials invasion and attack, and bacterium and acidic materials cause modal odontopathy, i.e. dental caries again.The mechanism of action of this fluoride is based on dental surface and forms calcirm-fluoride (CaF
2) ion of ease of solubility fluoride of layer, when the pH value in the saliva changed, fluoride discharged from the calcirm-fluoride layer and does not consume the storage fluoride of dental enamel.The antibacterial action of this fluoride also is described, and may be the generation that reduces diseased region bacterium acidic materials.These additives generally are dissolved in the toothpaste.
These additives are to join in the polymer bristle with solid, fine dispersion form in the toothbrush of being constructed according to the present invention.Additive is water soluble and/or saliva.Be embedded in cleaning element especially and constitute a kind of apotheca near the fine granular of surf zone, therefrom active material is dissolved out and is delivered to oral cavity and throat lentamente, particularly around denture.Because general employed polymer absorbs moisture to a certain degree, moisture enters the inside of bristle or moves out during drying after using.Because this physical process, additive is moved to the surface from the center of cleaning element in time, brings into play their effect at there.
The inorganic fluorine compounds of considering that can decomposite fluorine ion preferably is selected from sodium fluoride (NaF), sodium monofluorophosphate (Na
2PO
3F), zinc fluoride (ZnF
2), ammonium fluoride (HN
4F) and those of fluosilicate.
Be embedded in the polymer and be exposed at especially the surface fluorine compounds, when using dental care apparatus in conjunction with saliva or the water that is used to clean, form a fluoride source that slowly flows out, the natural fluoride that it constantly replenishes dental enamel stores, in case of necessity in conjunction with the toothpaste of corresponding doping.
In the polymer of bristle, add the non-soluble additives of other inertia with discrete form, to increase mechanical cleaning action.This is familiar with as everybody for the bristle of toothbrush in this measure, to produce certain rubbing action.In conjunction with additive of the present invention, the additive of these pure mechanisms must be an inertia.Particularly they should not be surface-active, mustn't increase their surface in use yet.These fine dispersion, frictional property particle wash away when using toothbrush in time.Thus, on bristle, expose new surface and therefore show the fluorine compounds that protect tooth.
In order to ensure the useful effect of additive, recommend bristle to have the level and smooth shape of non-stretching, extension, profile of tooth for example, waveform or screw winding shape are to enlarge their surface.On the contrary, bristle can be napping also, and wherein face fibre is filled with additive.
Another favourable embodiment feature is that bristle includes core and exodermis, and they are extrusion molding together, and additive is added in exodermis.
In this structure, core is formed by a kind of polymer especially, this polymer gives cleaning element necessary operating characteristic, as hot strength, bending property and anti-reversed bending strength (recoverability), and select the exodermis polymer mainly to discharge angle continuously from the embedding and the additive of additive.
Combine with the present invention, the toothbrush that interchangeable bristle is housed is used in special recommendation, that is, and and so-called replaceable head toothbrush.If because the wearing and tearing and the cleaning action that reduces gradually of bristle or increase danger to gums day by day recommend frequent conversion toothbrush or change this interchangeable head, then the bristle of filling is often changed even is had a bigger meaning according to the present invention.The tight each other juxtaposed toothbrush of bristle is particularly advantageous at this, can hold on a common head toothbrushes surface to reach 2000 bristles.
The present invention also relates to the method by the above-mentioned bristle of polymer manufacture that is used for toothbrush, is to be undertaken by the polymer melt extrusion molding, sneaks into the separable inorganic fluorine compounds that goes out fluoride of the fine dispersion form of water soluble and/or saliva in polymer melt.
Actual test has shown known and exist with crystal or amorphous form and the separable fluorine compounds that go out fluorine ion as salt or hydrofluoric acid because of its dental care benefits, when sneaking into polymer melt, there are not chemistry or damage physically, enough heat endurances are promptly arranged, and extrude and cured polymer in exist with constant form.The fine dispersion of additive distributes and can reach with all other solid the same manners, and they all are to process in polymer with the fine dispersion form, for example, and dyestuff or the like.
Additive is preferably selected from sodium fluoride (NaF), sodium monofluorophosphate (Na
2PO
3F), zinc fluoride (ZnF
2), ammonium fluoride and fluosilicate.
The additive preferred amounts that adds in the melt is 1500～4500ppm.Accurate ratio is in its reactivity of polymer surfaces when depending on the character of fluorine compounds and using toothbrush.
Preferably also sneak into inertia, non-soluble additives to increase mechanical cleaning action in polymer melt, they are rinsed when using toothbrush at leisure, and expose and have the new Free Surface that protects the tooth active additive.
The polymer that is used for bristle is selected from polyamide, polyolefin, polyester, polyacetals, sulphur polymer and their copolymer.
In order to form core and exodermis bi-component bristle, additive is joined in the polymer melt of exodermis.
