The clinical use of Activa self-ligating brackets

Area of Science:

• Orthodontics
• Biomaterials Science

Background:

• Self-ligating brackets are increasingly used in orthodontics.
• Understanding their clinical performance is crucial for effective treatment planning.

Purpose of the Study:

• To evaluate the advantages and disadvantages of Activa self-ligating brackets.
• To provide practical recommendations for managing encountered issues.

Main Methods:

• Clinical experience with Activa self-ligating brackets.
• Review of available data on frictional forces between arch wires and brackets.

Main Results:

• Principal advantages include very low friction and excellent arch wire engagement control.
• Potential benefits include rapid alignment of irregular teeth and facilitated sliding mechanics.
• A significant drawback is a higher bond failure rate compared to conventional brackets from the same manufacturer.

Conclusions:

• Activa self-ligating brackets offer unique benefits in orthodontic treatment.
• Addressing the higher bond failure rate is essential for optimal clinical outcomes.
