Abstract
A process by means of which the colonization by plaque on dental materials can be permanently prevented or delayed without the product properties of the dental material being negatively influenced. The process involves equipping the dental material with anti-plaque substance, namely at least one molecularly dispersely distributed octenidine salt or dequalinium salt. Also disclosed is a dental material so equipped.
Claims17
Dental material equipped with active anti-plaque substance, said dental material comprising at least one molecularly dispersely distributed octenidine salt or dequalinium salt, wherein
- the salt is present in a dissolved form molecularly dispersed in one or several (meth)acrylate based dental monomers;
- the salt has at least one anion from the group consisting of chloride, sulphate, phosphate, fatty acid anions, carboxylic acid anions, alkyl sulphonic acids and aryl sulphonic acids, alkyl sulphates and aryl sulphates;
- the material comprises at least one polymerization initiator.
Process for equipping dental material based on (meth-)acrylate with anti-plaque properties, said process comprising distributing at least one octenidine salt or dequalinium salt in a dissolved form and molecularly dispersed manner in one or several a (meth-)acrylate monomers before polymerizing the one or several monomers, the salt has at least one anion from the group consisting of chloride, sulphate, phosphate, fatty acid anions, carboxylic acid anions, alkyl sulphonic acids and aryl sulphonic acids, alkyl sulphates and aryl sulphates, and adding at least one polymerization initiator to the monomer.
