Beta-titanium alloys have distinct mechanical properties that give them advantages in orthodontic applications, particularly in terms of elasticity and flexibility. One of the key benefits is their higher range and springback compared to stainless steel. This means that beta-titanium can undergo greater deformation without permanent change, allowing for more effective force delivery and control during orthodontic treatment. This characteristic is particularly useful in applications such as archwires, where maintaining a specific force over a range of movement is important for effective tooth movement while minimizing the risk of dental tissue injury.

In contrast, while other materials may excel in certain areas, beta-titanium's unique combination of springback and lower stiffness compared to stainless steel makes it particularly beneficial in orthodontic applications, allowing for gentler, more effective forces on the teeth.
