Answer to Question #69180 in General Chemistry for natasha

Question

Describe how different types of corrosion may develop when metallic materials are selected for use in the oral environment. Make clear how the cell is produced and include appropriate examples (based on fixed, removable or orthodontic devices).

Answer 1

Answer:
Oral environmental is characterized by the constant elevated acidity. Therefore, this may cause acidic corrosion. This is when compounds formed by acidic and metallic irons are soluble. In order to avoid this, mostly noble metals are used for orthodontic devices.
Additionally, while designing orthodontic devices, the possibility of galvanic corrosion between 2 types of metals with different potential must be taken into account. Therefore, such devices are aimed to be constructed from the one type of metal.
