Gli attacchi sono collegati da fili ortodontici, chiamati archi, in modo da poter essere mossi insieme ai denti tramite sistemi di molle e ancoraggi di vari materiali uniti da diversi processi. Ciò favorisce la formazione di una pila galvanica e il rilascio di nichel da parte dell’apparecchio, causando allergie. Questo lavoro aveva lo scopo di applicare la tecnica degli anodi sacrificali utilizzata per la protezione catodica di strutture metalliche esposte a mezzi salini. Questa tecnica è stata applicata alla protezione dell’acciaio inossidabile e delle sue combinazioni con altri metalli utilizzati nei trattamenti ortodontici, non per proteggere la struttura, ma per proteggere la cavità orale dai danni causati dal nichel. La quantità di nichel rilasciata è rimasta al di sotto del limite di rilevabilità dell’apparecchiatura di assorbimento atomico elettrochimico utilizzata in questo lavoro. Ciò convalida il metodo di protezione catodica nella riduzione del rilascio di nichel dagli apparecchi ortodontici in acciaio inossidabile.
