The Hawley retainer, one of the most common types, is a removable retainer made of a combination of metal wires and sturdy acrylic, and is designed to keep your teeth in place. This retainer is specially made from impressions of your teeth so that it fits snugly and comfortably in the roof of your mouth, while any wire or acrylic framing keeps your teeth in perfect position. The acrylic can also be personalized with numerous colors and/or patterns.
Bonded Lingual Retainers
Bonded lingual retainers are cemented directly to the inside surface of your lower front six teeth. This is one of the best ways to prevent your lower teeth from shifting as it is permanently attached! Patients with bonded lingual retainers must be careful with their bite as the bonding material may break due to incorrect biting and cause teeth to shift quickly. As with removable retainers, it is important to keep them clean. When brushing, make sure to carefully clean the inside of your lower teeth as well as the wire.
The Essix retainer is a transparent removable retainer that fits over the entire arch of teeth. Essix retainers are used primarily to retain teeth in patients with a history of clenching and grinding. Because they have no wires, they have limited adjustability and therefore must be worn faithfully.
