Definitions
- Patent application Heraeus Kulzer GmbH / Antimicrobial nanosilver additive for polymerizable dental materials
- the invention relates to polymerizable dental materials containing elemental silver as an antimicrobial additive.
- Polymerizable dental materials such as. B. filling composites
- This shrinkage can, despite the use of adhesives, which are intended to ensure an optimal connection of the filling material to the tooth substance, lead to the formation of marginal gaps and, as a result, to colonization with microorganisms and thus to secondary caries.
- Silver is known as a germicidal additive.
- the silver generally does not become elementary, but in the form of glasses (US 6,593,260 B2, Ishizuka Garasu Kabushiki Kaisha), core-shell particles (US 5,180,585, Du Pont de Nemours), co-doping Core-shell particles (US 5,180,585, Du Pont de Nemours), co-doping on silica (EP 1 083 146 A1, Degussa), complex silver compounds (US 5,985,308, Westham Technologies) applied to zeolites etc.
- Porous silver particles with diameters in the lower micrometer range are also known (DE 101 46 050 A1, WO 03/024494 A1, DE 102 05 600 A1, WO 02/17984 A1).
- the proposed silver particles are usually a few micrometers in size and, moreover, mostly aggregated / agglomerated.
- the material therefore always has a dark inherent color.
- the use in tooth-colored dental materials is therefore out of the question for most of the silver materials described in these documents, since even in low concentrations product properties such as color and transparency can be negatively influenced.
- a polymerizable dental material which contains nanoscale silver particles as an antimicrobial additive, which have> a primary particle diameter ( ⁇ 40 nm, preferably 1-40 nm, particularly 1-20 nm). (This means that they do not cause light-optical refraction and diffraction effects).
- Antimicrobial activity can already be achieved with 1 ppm silver, in particular 10 ppm and preferably 100 ppm silver.
- the silver content can be up to 10% by weight and is preferably below 5% by weight, in particular below 2% by weight.
- the particles preferably have or do not have at least one of the following further features, namely that they are: homogeneously incorporated into the dental material and thus do not represent a surface coating. For this reason, there can be no loss of effectiveness due to the wear of the coating that occurs naturally with filling materials, for example.
- the bulk material always represents a kind of silver depot from which silver can diffuse outwards or is consumed by solution processes. This guarantees a long-term effect. > are not agglomerated, because an agglomeration would lead to optically negative effects,> are not applied to carrier or auxiliary substances; > are provided with a surface modification for incorporation; > be introduced into the dental material in the form of an acrylic dispersion.
- the proposed material has the following advantages:
- the nanoscale particle diameters result in a very high specific surface. As a result, the total silver concentration in the filling composite can be kept relatively low, and the long-term antimicrobial effect is nevertheless ensured.
- the nanoparticles do not appear black or gray in the light, as is usual with silver, but do not affect the color of the dental material.
- the transparency of the material is not significantly reduced since the particle size falls below the wavelength of visible light ( ⁇ 1/20 of the spectral range 420 to 750 nm).
- a problem with the use of silver is that excessively high concentrations of silver ions can have a toxic effect (DE 102 05 600 A1). The formation of high concentrations of soluble silver compounds is therefore not desirable. These problems cannot arise with the proposed material.
- a nanoparticle silver suitable for the materials according to the invention is e.g. offered by the company Bio-Gate Bioinnovative Materials in Nuremberg.
- the coating of textiles, tissues, materials for implantation in bones and adhesives and coating materials are mentioned as application suggestions.
- the silver is preferably contained in the dental material at 0.05 to 0.5%.
- the materials according to the invention are suitable in the dental field e.g. as filling composites, denture base materials, adhesives, crown and bridge veneering composites, and as materials for artificial teeth.
- Another sample is taken and cured with a "Translux Energy” lamp. There is no color difference between the two hardened samples.
