Abstract

To assess the efficacy of a prototype cleaning device in removing biofilm from skin-penetrating abutments. Adverse skin reactions around percutaneous osseointegrated implants have been linked to poor hygiene and infection. A cleaning device made from open-cell polyfoam has been developed to facilitate manual cleaning of abutments by the patient. Serratia biofilm was grown on clean and sterile conical bone-anchored hearing system abutments including both pre-2007 (straight sided) and post-2007 (conical-sided) designs. Eighteen were photographed and then subjected to cleaning using a toothbrush or the cleaning device soaked in water or a proprietary mouthwash. Biofilm on a further group of 10 conical abutments was recorded using a scanning electron microscope before and after cleaning with the test device soaked in water. Quantitative analysis of the efficiency of the cleaning was made using image analysis. Removal of biofilm using a dry or wet toothbrush was not as effective as cleaning with the device. In 10 cases subjected to image analysis, approximately 90% of the biofilm was removed from the top third of the abutments, 85% from the middle third, and 48% from the basal third. The cleaning device is effective in removing most...Continue Reading
