Corrosion of dental alloys used for mini implants in simulated oral environment
The aim of this study was to explore the resistance to general and pitting corrosion of stainless steel and titanium-based orthodontic mini implants in an oral environment. Studies were performed in artificial saliva and in the presence of two oral hygiene products (one containing chlorhexidine digluconate with sodium fluoride and another containing probiotic bacteria) that are usually recommended to orthodontic patients. The results showed that mini implants made from stainless steel have lower resistance to corrosion than titanium implants. General corrosion was increased in both steel and titanium implants when antiseptic agents containing fluoride ions were used, while the tendency towards pitting corrosion was not noticeably altered. Probiotics, on the other hand, had a beneficial effect on general corrosion resistance but were associated with an increased tendency towards pitting corrosion for both implant materials.

This research was supported by the Croatian Science Foundation under Grants IP-2014-09-7500 [Immunological and regenerative implications of corrosion of dental materials in children and adolescents] and IP-2020-02-4027 [Environmental factors and microbial interactions in the structure of the dental biofilm]. Some of the equipment used was funded via the ERDF project RC.2.2.06-0001 [Research infrastructure for campus-based laboratories at the University of Rijeka].
