What is the most common type of removable retainer?

1. Hawley retainer

2. Bonded retainer

3. Essix retainer

4. Inactive retainer

The correct answer is: Hawley retainer

The Hawley retainer is considered the most common type of removable retainer primarily due to its durability and effectiveness in maintaining teeth positions following orthodontic treatment. It is constructed from a combination of acrylic and metal wires, which allows it to be adjusted for a proper fit and corrective purposes. One of the key benefits of Hawley retainers is their ability to allow for slight tooth movement over time if necessary, as they can be adjusted by an orthodontist. This flexibility makes them a preferred choice for many practitioners. In contrast, other types of retainers, such as the bonded retainer, are fixed and cannot be removed by the patient, which limits patient control over their wear. The Essix retainer, while also popular, is made of clear plastic and may not be as durable as a Hawley retainer, especially for patients who may need more robust retention. An inactive retainer typically refers to a device that is no longer providing active retention but does not describe a specific removable retainer type. Overall, the combination of adjustability, durability, and effectiveness in maintaining orthodontic results contributes to the Hawley retainer's standing as the most commonly used removable orthodontic retainer.
