Effect of self-locking bracket appliance in the correction of Angle class Ⅱ class 1 malocclusion

  •   Objective  To study the effect of self-locking bracket appliances on correction efficacy of Angle class Ⅱ malocclusion patients scored 1.
      Methods  A total of 40 patients with class Ⅱ malocclusion scored 1 in our hospital were selected in the study. The control group with 20 patients were treated with traditional ligation brackets, while 20 patients in the observation group were treated with self-locking bracket appliances for correction. The pain, re-visit and corrective effect were compared between the two groups.
      Results  The VAS scores of the patients in the observation group at 6, 24, 48 h and 3, 4 and 7 days after treatment were significantly lower than those of in the control group (P < 0.05). The number of routine visits, treatment time and bracket drop-off rate in the observation group were significantly better than those in the control group (P < 0.05).
      Conclusion  Self-locking bracket appliance can effectively relieve pain and other discomforts of patients, and improve the correction effect.
