Definitions

  • the present invention relates to a polymeric dental material having microbiocidal activity.
  • polymeric dental materials in particular those based on (meth) acrylate, tend to form plaque with prolonged use and poor dental hygiene. Attempts have been made to reduce the harmful plaque formation and also the risk of infection by adding a biocidal active substance.
  • the biocidic agent is a polymeric condensation product formed from a guanidine derivative and an oxyalkylene diamine.
  • Such polymeric guanidine derivatives are e.g. from WO 01/85676 A1, AT 406 163 B and WO 06/047800.
  • biocidal active substance can be washed out of the dental material over time, whereby the plaque formation is favored again.
  • This object is achieved according to the invention with a polymeric dental material containing a siliceous filler which is modified with a polymeric guanidine derivative based on an alkylenediamine and / or an oxyalkylenediamine.
  • the invention is based on the surprising observation that these polymeric guanidine derivatives bind so strongly to silicates that they are practically no longer soluble in water, from the dental material can not be washed out, but still have the microbiocidal effect.
  • Silastic fillers for polymers are known per se. Now, when these fillers are modified with the polymeric guanidine derivative and incorporated into the polymer, they impart the plaque-inhibiting property to the polymer, although they are tightly bound to the siliceous filler.
  • a preferred embodiment of the polymeric dental material according to the invention is characterized in that a polymeric guanidine derivative is provided which contains the alkylenediamine and the oxyalkylenediamine in a molar ratio of between 4: 1 and 1: 4.
  • the amino groups of the alkylenediamine and / or the oxyalkylenediamine are preferably terminal, wherein for the preparation of the polymeric guanidine derivative as the alkylenediamine in the first place, a compound of the general formula
  • n is an integer between 2 and 10, in particular 6, is.
  • polymeric guanidine derivative for the preparation of the polymeric guanidine derivative can as oxyalkylene diamine a compound of the general formula
  • n is an integer between 2 and 5, in particular 2.
  • a polymeric dental material which is characterized in that a polyoxyalkylene guanidine based on triethylene glycol diamine (relative molecular mass: 148), of polyoxypropylene diamine (relative molecular mass: 230) and / or of polyoxyethylene diamine (relative molecular mass: 600) is used as the polymeric guanidine derivative. is provided.
  • silicate filler in which is provided as the polymeric guanidine derivative poly [2- (2-ethoxyethoxyethyl) guanidinium hydrochloride] having at least 3 guanidine residues.
  • the polymeric guanidine derivative has an average molecular weight in the range of 500 to 3,000.
  • the filler may be contained in an amount between 0.05 and 5.0 wt .-%.
  • the polymer is a curable plastic, preferably based on acrylate or methacrylate.
  • silicate filler is not only powdery SiO 2 , but also finely divided silicas and other silicates, especially those that are used today as fillers in plastics technology.
  • the binding of the polymeric guanidine derivative (active ingredient) to the siliceous filler, that is to say the carrier matrix, takes place by presentation of the matrix, which consists, for example, of fine Aerosil Types may exist and mixing a 1-30% Gew. - aqueous solution of the active ingredient at room temperature in a stirred tank.
  • the water can then be removed using conventional technologies, such as fluid bed dryers.
  • the matrix-bound active substance in this form is still very effective against microorganisms, but it is so strongly bound to the filler that it is virtually insoluble in water and can be washed out.
  • the described matrix fixation of the active ingredient thus prevents the migration of the active ingredient in aqueous media. Migration into fatty media is also not possible due to the insolubility of the polar agent.
  • dental materials in a broader sense are suitable, including materials used in the field of orthodontics or maxillofacial surgery or dental cosmetics / aesthetics.
  • materials used in the field of orthodontics or maxillofacial surgery or dental cosmetics / aesthetics are e.g. Filling composites, K & B veneering plastics (for crown and bridge), denture resins, dentin bonding, impression materials, impression trays, temporary K & B materials, implants, dental equipment, dental braces or ligaments, bone cements for maxillofacial surgery and applications for it.
