Anti-microbial dental impression material

摘要

The invention relates to plastics which are self-disinfecting. The invention relates in particular to polyether or silicone based dental plastics and impression materials in which a biocidal material is incorporated. The dental impression material ace. to the invention comprises at least a polymerizable base paste BP and a non-aqueous catalyst paste CP, wherein the base paste BP comprises about 0.001 to about 10% by weight of a water-stable anti-microbial agent. Preferred anti-microbial agents are selected from the group consisting of Hexitidin, Cetypyridininumcloride (CPC), Chlorhexidine and its derivates (CHX) and Triclosan.

1. A dental impression material comprising at least a polymerizable base paste (BP) and a non-aqueous catalyst paste (CP), wherein the base paste (BP) comprises about 0.001 to about 10% by weight of a water-stable anti-microbial agent and the catalyst component comprises a catalyst for polymerizing the base component and wherein the anti-microbial agent does not increase the time measured until the start of polymerization after combining components BP and CP by more than a factor of about 2, and wherein the anti-microbial agent is selected from the group consisting of salts of chlorhexidine (CHX), wherein CP is free of boric acid complexes, wherein the anti-microbial agent is the only anti-microbial agent present in the dental impression material.
