ORTHODONTIC MATERIAL

THE CORROSION RESISTANCE PROPERTY OF STAINLESS STEEL IS BY

• CARBON

• IRON

• NICKEL

• CHROMIUM

Nickel-titanium (NiTi) wires are particularly known for their:

• Shape memory and super-elastic properties

• High corrosion resistance

• Low cost

• Increased stiffness

Titanium-molybdenum (Ti-Mo) alloys are often used in orthodontics because they provide:

• Enhanced shape memory

• Excellent elasticity with moderate strength

• Superior corrosion resistance but low elasticity

• High stiffness but low formability

Which of the following is a characteristic of stainless steel orthodontic wires?

• Excellent shape memory effect

• High stiffness and strength, but low flexibility

• Low corrosion resistance

• High cost

Which of the following orthodontic wire materials is most commonly used for initial leveling and aligning due to its low stiffness and high elasticity?

• Stainless Steel

• Beta-Titanium

• Nickel-Titanium (NiTi)

• Cobalt-Chromium
