Abstract: An improved adjustable attachment for a labial arch retainer. The retainer is of the type having a palatal section configured to conform to the roof of the mouth of a patient, a pair of extension wires extending anterially from the palatal section, an attachment hook provided at the terminal end of each extension wire, and a resilient synthetic band adapted to exert pressure against the teeth of the patient. The adjustable attachment is connected between the resilient band and the attachment hook in a manner which permits the length of the resilient band to be varied thereby permitting adjustment of the pressure exerted against the teeth of the patient.
