A representative ex-situ fretting wear investigation of orthodontic arch-wire/bracket contacts

In this study the friction force between brackets and arch-wires during combined macro-/micro-slidings has been investigated. Various stainless steel bracket/arch-wire contacts have been analyzed. The wear and friction properties of different PEPVD deposited coatings such as SiC and SiN have been studied under dry and wet artificial saliva conditions.
