Retainers
Retainers are required to be worn once treatment with braces is complete. The orthodontist will recommend a retainer based on the patient’s needs. If a patient does not wear the retainer as recommended, the teeth might move towards their original position (relapse). A Hawley retainer is made of metal hooks that surround the teeth and are enclosed by an acrylic plate shaped to fit the patient’s palate. An Essix retainer is similar to Invisalign trays. It is a clear plastic tray form-fitted to the teeth and stays in place by suction. A bonded retainer is a wire permanently bonded to the lingual side of the teeth (usually the lower teeth only). -Source
