Definitions
- the invention relates to a toothbrush with bristles an extruded polymer that is at least close to the surface Area with water- or saliva-soluble additives contains dental effects, as well as a procedure for the production of such bristles for a toothbrush.
- Bristles have also been proposed, at where the polymer has antibacterial metal ions, e.g. in the form of zeolite (Derwent abstract 91-004868 / 01 JP 02-283312A) or antimicrobial, soluble contains organic additives (Derwent abstract 94-217929 / 26 to WO 94/13870 A1), and US-A-5 276 935.
- antibacterial metal ions e.g. in the form of zeolite (Derwent abstract 91-004868 / 01 JP 02-283312A) or antimicrobial, soluble contains organic additives (Derwent abstract 94-217929 / 26 to WO 94/13870 A1), and US-A-5 276 935.
- the invention has for its object the scope to expand the well-known toothbrushes.
- Additive inorganic fluorine compounds that act split off fluoride from water and / or saliva, incorporated into the polymer in solid, finely dispersed form are.
- the mechanism of action of such fluorides is based on the fluoride ions of easily soluble fluorides, which form a calcium fluoride (CaF 2 ) layer on the tooth surface, from which fluoride is released when the pH value changes in the saliva without stressing the fluoride reservoir of the tooth enamel.
- the antibacterial effect of such fluorides is also described, which presumably reduces the acid production of the bacteria in the plaque.
- Such additives are usually present in dissolved form in dentifrices.
- these additives in solid, finely dispersed form bristles incorporated into a polymer.
- the additives are water and / or saliva soluble.
- the particular one in the area of the cleaning element near the surface embedded fine particles form a kind of reservoir, from which the active substance is slowly released and into the mouth and throat, especially in the area of the Bit is given because the commonly used Polymers absorb moisture to some extent penetrates into the interior of the bristle or when drying emigrates after use. Through this physical Processes also migrate the additives out of time Core of the cleaning element to the surface in order to to exert their effect there.
- Inorganic fluorine compounds which release fluorides are preferably those from the group consisting of sodium fluoride (NaF), sodium monofluorophosphate (Na 2 PO 3 F), zinc fluoride (ZnF 2 ), ammonium fluoride (NH 4 F) and fluorosilicates.
- the embedded in the polymer and especially on the Exposed fluorine compounds form on the surface Use of the dental care device in connection with the Mouth saliva or the water used for cleaning a slow flowing fluoride source that is natural Fluoride balance of the enamel, if necessary in connection with appropriately doped dental care products continuously updated.
- bristles that increase their surface area a shape that deviates from the elongated, smooth shape have, e.g. profiled, wavy or spirally wound are. Instead, the bristles can also be flocked be, the flock fibers also being filled with the additives are.
- bristles consist of one soul and one Sheath exist, which are co-extruded, the additives are incorporated into the coat.
- the soul can be out a polymer that the cleaning element necessary usage properties, such as tensile strength, Flexibility and fatigue strength (re-erection ability) there while the polymer for the coat primarily with regard to the embedding of the additives and its successive delivery is selected.
- the invention further relates to a method of manufacture the aforementioned bristles made of a polymer for Toothbrushes by extruding the polymer from a Melt, the water- and / or saliva-soluble inorganic, Fluoride-releasing fluorine compounds in finely dispersed Form to be mixed.
- Fluoride-releasing fluorine compounds that act as salts or hydrofluoric acid is in crystalline or amorphous form, when admixed to a polymer melt chemically and not be physically impaired, so sufficient are temperature stable, and in the extruded and cured polymer in unchanged form.
- a finely dispersed distribution of the additives can be found in same way as with all other solids, processed in finely dispersed form in polymers e.g. Color pigments or the like
- the additives are preferably selected from the group consisting of sodium fluoride (NaF), sodium monofluorophosphate (Na 2 PO 3 F), zinc fluoride (ZnF 2 ), ammonium fluoride (NH 4 F) and fluorosilicate.
- the additives are preferably 1500 in the melt up to 4500 ppm added. The exact proportion depends on the Type of fluorine compound and its implementation in the surface of the polymer while using the toothbrush from.
- the polymer melt is preferably also inert, insoluble additives to increase the mechanical cleaning effect mixed in when using the toothbrush be washed out slowly and new free surfaces Expose with the dentistically effective additives.
- the polymers used for the bristles are made from the Group of polyamides, polyolefins, polyesters, polyacetals, Sulfur polymers and their mixed polymers selected.
