<p>The device e.g. tooth clip (30), has an anti-bacterially operative depot (10) comprising continuously deliverable silver ions. The depot is fastened to the tooth clip in a form of a cap. The silver ions are applied as colloidal silver coating on a part of the tooth clip and/or on the depot. The depot is fastenable to a tooth implant, where low electrical voltage is produced between the depot and another anti-bacterially operative depot after mounting the device in mouth. The silver ions are embedded in a matrix of metal, plastic or ceramics.</p> |
