What is the most common type of attachment for fixed orthodontic appliances?

The most common type of attachment for fixed orthodontic appliances is the bonded bracket. Bonded brackets are small devices that are adhered directly to the teeth using a dental adhesive. They play a crucial role in the orthodontic treatment process, as they hold the archwire in place and allow for the application of controlled forces on the teeth, facilitating movement into the desired position.

Bonded brackets are favored due to their efficiency in providing a secure and stable support system for the brackets. They can be made from various materials, including metal and ceramic, allowing orthodontists to choose options that are aesthetic or more durable based on the patient's needs. The bonding technique provides a lower profile and smoother surface, which improves patient comfort and makes oral hygiene easier compared to other attachment methods.

In contrast, while elastic bands, metal bands, and wire ligatures also play important roles in orthodontic treatment, they are not the primary attachment mechanism for fixed appliances. Elastic bands are typically used in conjunction with fixed appliances to create additional forces for tooth movement. Metal bands are used less frequently today, primarily for molars or teeth that may not respond well to bonded brackets. Wire ligatures are used to secure wire to the brackets but do not serve as the primary means of attachment for fixed appliances
