Definitions

  • the invention relates to a dental care device with at least one cleaning element made of an extruded polymer and a method for producing such cleaning elements for a dental care device.
  • Dental care devices of the abovementioned construction are understood to mean both mono- or multifilament fibers and, in particular, toothbrushes with a bristle trim which forms the cleaning elements.
  • Known dental care devices of this type only develop a mechanical cleaning effect due to friction between the cleaning elements and the tooth surface. In addition, they have a massage effect on the gingiva.
  • the cleaning elements of such dental care devices are generally obtained from polymers by extrusion, be it in the form of fibers, bristles or the like.
  • the invention has for its object to expand the scope of the known dental care devices.
  • the polymer of the cleaning element is filled, at least in its area near the surface, with water- and / or saliva-soluble additives with dental medicine and / or antibacterial activity in solid, finely dispersed form.
  • additives with dental medicine, antibacterial or deodorising effect are known for liquid and pasty dentifrices.
  • Such additives are added to the dentifrices in particular in the form of fluoride compounds in order to utilize their tooth-hardening effect.
  • the effect is based on the fact that the human tooth enamel has a relatively high fluoride concentration in its outermost layer, which quickly decreases in the depth of the tooth.
  • the amount of fluoride supplied with food and drinking water is usually not sufficient to keep the fluoride content in the tooth enamel stable.
  • the fluoride content is decisive for the resistance of the teeth to the attack of bacteria and acids, which in turn lead to the most common dental disease, namely caries.
  • such dental and / or antibacterial additives are incorporated in solid, finely dispersed form in the cleaning elements formed from a polymer.
  • the additives are water and / or saliva soluble.
  • the very fine particles embedded in particular in the area near the surface of the cleaning element form a kind of reservoir from which the active substance is slowly released and released into the mouth and throat, in particular in the area of the dentition, since the polymers usually used to a certain extent absorb moisture, which penetrates into the interior of the cleaning element or migrates when dry after use.
  • Inorganic fluoride-releasing fluorine compounds or xylitol are preferably used as additives, which are selected, for example, from the group sodium fluoride (NaF), sodium monofluorophosphate (a2P0 3 F), zinc fluoride (ZnF 2 ), ammonium fluoride (NH " 4 F) and fluorosilicates.
  • the fluorine compounds embedded in the polymer and in particular exposed on the surface form a slow-flowing fluoride source when the dental care device is used in conjunction with the mouth saliva or the water used for cleaning, corresponding to the natural fluoride balance of the tooth enamel, possibly in conjunction with it endowed dental care continuously updated.
  • insoluble additives to increase the mechanical cleaning action can be incorporated in disperse form in the polymer of the cleaning element. This measure is known per se for toothbrush bristles in order to achieve a certain abrasive effect.
  • such purely mechanical additives must be inert. In particular, they must not be surface-active or increase their surface area when in use. These finely dispersed, abrasive particles are washed out over time when using the dental care device. As a result, new surfaces are exposed on the polymer of the cleaning element and thus, in turn, dental or antibacterial additives.
  • the dental care device can be designed in a conventional manner as a toothbrush with a plurality of bristles which form the cleaning elements and are made of the filled polymer.
  • bristles are recommended which have a shape which deviates from the elongated, smooth shape in order to enlarge their surface, e.g. profiled, curled or spirally wound.
  • the cleaning elements can also be formed from flocked bristles, the flock fibers also being filled with the additives.
  • the bristles consist of a core and a mantile, which are coextruded, and the additives are incorporated into the jacket.
  • the core in particular, can consist of a polymer that gives the cleaning element the necessary usage properties, such as tensile strength, bending ability and flexural fatigue strength (re-erection ability), while the polymer for the jacket is selected primarily with regard to the embedding of the additives and their successive release .
  • toothbrushes that are provided with exchangeable cleaning elements so-called interchangeable head brushes
  • interchangeable head brushes are particularly recommended. If the frequent replacement of the toothbrush or the replacement of such interchangeable heads is recommended for reasons of wear and tear on the bristles and the consequent decreasing cleaning action or increasing risk to the gingiva, regular replacement of bristles filled according to the invention is even more important. Brushes with close-fitting individual bristles, of which up to 2000 can be accommodated on the surface of a conventional toothbrush head, are particularly advantageous.
  • the dental care device can also be designed in a conventional manner as a multifilament interdental cleaner, the polymer fibers forming it being filled with the additives.
  • the invention further relates to a method for producing cleaning elements, for example bristles made of a polymer for dental care devices, by extruding the polymer from a melt.
  • a method for producing cleaning elements for example bristles made of a polymer for dental care devices, by extruding the polymer from a melt.
  • the polymer melt has water- and / or saliva-soluble additives with a dental-medical and / or antibacterial effect in fine dispersed form mixed and the mixture is extruded.
  • the additives are preferably selected from the group consisting of sodium fluoride (NaF), sodium monofluorophosphate (Na 2 P0 3 F), zinc fluoride (ZnF 2 ), ammonium fluoride (NH 4 F) and fluorosilicate.
  • the additives are preferably added to the melt at 1500 to 4500 ppm. The exact proportion depends on the type of fluorine compound and its implementation in the
  • inert, insoluble additives are added to the polymer melt to increase the mechanical cleaning effect, which are slowly flushed out when using the dental care device and expose new free surfaces with dentistically effective additives.
  • the polymers used for the cleaning elements are selected from the group of polyamides, polyolefins, polyesters, polyacetals, sulfur polymers and their mixed polymers.
  • the additives of the polymer melt for the jacket are mixed.

Abstract

Appareil pour soins dentaires présentant au moins un élément de nettoyage en polymère extrudé, caractérisé en ce que dans le polymère de l'élément de nettoyage, dans la zone voisine de sa surface, au moins un additif soluble dans l'eau et/ou dans la salive, à effet médico-dentaire et/ou antibactérien, est incorporé sous forme solide finement dispersée. En outre, l'invention a pour objet un procédé d'obtention d'éléments de nettoyage en polymère pour appareil pour soins dentaires, caractérisé en ce qu'on incorpore, sous forme finement dispersée, à la masse fondue de polymère, un additif soluble dans l'eau et/ou dans la salive, à effet médico-dentaire et/ou antibactérien, et en ce qu'on extrude le mélange obtenu.
