[0033] Preparation of Dental Composite Containing Octenidine Dihydrochloride with Uniform Molecularly Dispersed Distribution Material

[0034] Under slight heat, octenidine dihydrochloride was dissolved in bis-GMA in an amount such that the final concentration of octenidine dihydrochloride in the composite was 3 wt. % to 6% by weight.

[0035]Filling was obtained by adding TEDA as reaction diluent, conventional photoinitiators and stabilizers and 65% by weight of dental glass with a particle size of about 1 μm and about 8% by weight of pyrogenic silicate Aerosil OX50 to adjust the rheology. composite material. Coloring pigments can be added to adjust the color if desired.

[0036] Preparation of Dental Composite Containing Octenidine Dilactate with Uniform Molecularly Dispersed Distribution Material

[0037] Octenidine dilactate was added to the mixture of UMDA, TEDA and aliphatic dimethacrylate in an amount such that the final concentration of octenidine dilactate w...

Abstract

The invention relates to a process for imparting anti-plaque property to dental materials by molecule dispersion distributed octenidine salt or dequalinium ammonium. The dental material with the active anti-plaque substance(s) contains at least one molecule dispersion distributed octenidine salt or dqualinium ammonium. Moreover, the invention describes a process for imparting anti-plaque propertyto a dental material based on (methyl)acrylic acid ester, wherein at least one from the octenidine salt and the dequalinium ammonium is distributed in a (methyl)acrylic aid ester monomers in a molecular dispersion before the polymerizing.

Description

technical field [0001] The present invention relates to dental materials provided with active antiplaque substances. Background technique [0002] For polymer dental materials introduced into the oral cavity to permanently reside therein, especially those based on acrylate / methyl methacrylate, plaque tends to will colonize the surface of the material. [0003] Plaque is made up of various bacteria that are firmly anchored to surfaces such as teeth or dental materials by means of proteins and carbohydrates. Other bacteria can then colonize this first bacterial layer, forming three-dimensional colonies. This "biofilm" is almost immune to antibiotic attack due to certain substances released by these bacteria. [0004] In addition to hygienic aspects, in severe stages, plaque can lead to intense discoloration, which is aesthetically disadvantageous. [0005] The state of the art is that plaque colonization can be reduced by preventing bacteria from adhering to the material e...
