Due to the growing interest in aesthetic solutions of an increasing numbers of young adults and adult patients, there is a need for new materials for fixed orthodontic treatment especially because the aligner systems cannot be used for difficult tooth movements. An alternative aesthetic option is the use of fixed lingual systems, which is very expensive and not suitable in some cases, or the use of ceramic braces, which however, cannot be used in the lower jaw due to enamel abrasion. To solve this problem a competitive product that meets both the mechanical and aesthetic requirements, and simultaneously offsets the disadvantages of multi-materials by an antimicrobial substance to reduce caries risk, is needed. The aim of the project is to develop metal-polymer hybrid components for dental application, whereat the material interface will be first enhanced by additively manufactured micro-topology (macro- and micro-structuring) and by ameliorating polymer infiltration in a second step. Additionally, an active anti-microbiological substance to reduce oral biofilm formation will functionalize the composite-material surface. Although various application scenarios are conceivable in dentistry, this project addresses the field of orthodontics, in particular the production of modern dental brackets based on this functionalized multi-material. So far, for aesthetic orthodontic treatment no material combining these functions is currently available at the market.
