Abstract Objective To evaluate the therapeutic effect of lingual straight wire orthodontic technology for class Ⅲ malocclusion. Methods Thirty patients with Angle class Ⅲ malocclusion treated with lingual straight wire orthodontic technology between October 2010 and October 2016 were selected. X-ray measurements of lateral cephalometric X-ray film of each patient before and after treatment were analyzed with software. A total of 19 markers were measured with reference to the studies by Peking University Health Science Center, Steiner, Tweed, and Coben, including 6 bone measurements, 8 dental measurements, 3 soft tissue measurements, and 2 vertical measurements. Paired measurements by t test were used to compare the difference before and after treatment. Results After treatment, the SAN angle, ANB angle, and the distance of the upper lip to the lower lip were significantly different (P<0.01). The labia-inclination of upper incisors (U1-SN、U1-NA) and inclination of lower incisors (L1-NB) increased. The overjet was (-1.76±0.29 ) before treatment and (1.08±0.20) after treatment, so the increase was significant. The anterior crossbite was relieved (P<0.01). Conclusions The lingual orthodontic technique can successfully correct the malformation of Angle class Ⅲ malocclusion in permanent teeth, so that the maxillofacial and soft tissue profile of the patients can be improved obviously.
