Abstract
Biofilm formation on dental implant surfaces is a serious threat. Up to 50% of all implants show signs of irreversible tissue destruction. The aim of the present systematic review was to summarize the state of the art of strategies to functionalize antimicrobial dental implant surfaces. We searched the following electronic database: SCOPUS, MEDLINE and GOOGLE SCHOLAR and identified relevant controlled trials that evaluated the efficiency of new biomaterial strategies to modify dental implant surfaces, in such a way that biofilm formation was inhibited. The search yielded 2,990 potentially relevant publications. A total of 142 publications met the inclusion criteria. Analysis found that it may be concluded that silver-implanted surfaces, drug-loaded surfaces, surfaces with antimicrobial peptides, bioactive and biopassive polymer coatings as well as nanoscale or UV-activatable surfaces enhance antimicrobial activity compared to commercial pure titanium.
