Mandibular dental arch changes with active self-ligating brackets combined with different archwires.
Niger J Clin Pract. 2018 May; 21(5):566-572.NJ

Abstract

OBJECTIVE

The aim was to compare mandibular arch and incisor inclinational changes by comparing active self-ligating brackets used with different forms of archwires with a control group in nonextraction cases.

MATERIALS AND METHODS

The sample of 50 patients with Class I malocclusion was divided into three groups: Group I was treated with active self-ligating brackets (Nexus, Ormco/Orange, CA, USA) used with Damon arch form copper nickel-titanium (Cu-NiTi) and stainless steel (SS) wires; Group II was treated with interactive self-ligating bracket system (Empower, American Orthodontics, Sheboygan, Wis, USA) used with standard Cu-NiTi and SS wires; and Group III was treated with Roth prescribed conventional brackets (Forestadent, Pforzheim, Germany) with standard Cu-NiTi and SS wires which was designed as a control group. Changes in dimension of mandibular arch and inclination of incisors were assessed on dental models and lateral cephalometric radiographs at pretreatment (T1) and posttreatment (T2) periods. Paired-t test and one-way analysis of variance were used to perform intragroup and intergroup comparisons, respectively.

RESULTS

In all groups, an average increase of transversal distances occurred from pretreatment to the posttreatment period (P < 0.05). However, mandibular arch length increase was significantly different among the Groups I-III (P = 0.008) and I-II (P = 0.006). No significant intergroup difference was found with regard to incisor inclinational changes.

CONCLUSIONS

Bracket type had no significant effect on the mandibular dimensional or incisor inclination changes. Besides this, archwire type had only little effect on the treatment results as active self-ligating bracket with Damon archwires increased mandibular arch length greater than other groups.
