ABSTRACT:
An arch wire for correction of anterior tooth malformations comprising a continuous, unitary, solid wire having circular cross-sections at least in its anterior segments and preferably throughout its length with the cross-sections of the anterior segments being smaller than the cross-sections of the posterior segments. The narrow anterior segment is easy to install and comfortable to the patient, while the larger posterior segments are more stiff and less likely to damage the patient's gums or pull out of the buccal tubes on the patient's molars even when the parts of the wire adjacent to the bicuspids and canines are unsupported.
