A dental appliance, such as of the orthodontic type, to be placed in the mouth and having an inorganic antimicrobial agent on a surface, the agent preferably being a zeolite. The dental appliance may comprise metal or a polymer and the agent may be present in a coating that is applied to the surfaces of the appliance that are to be contacted by liquids or solids in the mouth. The appliance can be of a polymer resin or an elastomer incorporating the agent. A preferred antimicrobial agent is ceramic particles (e.g., zeolite particles) containing antimicrobial metal ions, e.g., silver ions, as the active agent. |
