An in vitro investigation of the effects of surface corrosion on the metal element content and tensile strength of orthodontic silver brazed stainless steel joints arising from varying exposure periods in Fusayama's artificial saliva

Abstract

Globally in the field of Dental Technology, brazing continues to be the prevailing joining technique for removable orthodontic appliances. However, the strength of the brazed joint is a growing concern to dental technicians since the commonly employed silver solder brazing material undergoes changes in brazed joint composition (microstructure) thereby enhancing corrosion susceptibility. This ultimately influences the success of orthodontic appliances intra-orally.

The objective of this in vitro investigation was therefore to determine the effects of corrosion on the composition and tensile strength of orthodontic silver brazed stainless steel joints after varying exposure periods in Fusayama’s artificial saliva.
