Abstract
ObjectiveTo compare and analyze the effects of invisible orthodontics and fixed orthodontics in the treatment of anterior tooth adduction.
MethodsEighty-six patients with anterior teeth adduction treated in Nanyang Central Hospital from January 2019 to January 2022 were selected and divided into invisible orthodontics group and fixed orthodontics group according to random number table method, with 43 cases in each group. The fixed orthodontics group was treated by fixed orthodontics, and the invisible orthodontics group was treated by invisible orthodontics. The total effective rate of orthodontics, periodontal health indexes, including gingival bleeding index (GBI), plaque index (PLI) and gingival index (GI), cephalometric results (angle of upper and lower central incisors, angle between lower central incisor and mandibular plane), incidence of complications, and satisfaction of orthodontics were compared between the two groups.
ResultsThere was no statistically significant difference in the total effective rate of orthodontics between the invisible orthodontics group (93.02%, 40/43) and the fixed orthodontics group (88.37%, 38/43), P>0.05. After 1 year of treatment, the scores of GBI, PLI and GI of the invisible orthodontics group were lower than those of the fixed orthodontics group (all P<0.05). There was no significant difference in cephalometric results between the invisible orthodontics group and the fixed orthodontics group before and 1 year after correction (P>0.05). The incidence of complications in the invisible orthodontics group was 2.33% (1/43), which was lower than the 18.60% (8/43) in the fixed orthodontics group (P<0.05). The satisfaction of orthodontics in the invisible orthodontics group was 97.67% (42/43), which was higher than the 81.40% (35/43) in the fixed orthodontics group (P<0.05).
ConclusionsBoth invisible orthodontics and fixed orthodontics can achieve good orthodontic effects. However, invisible orthodontics can improve periodontal health, reduce the incidence of complications, and improve patients’ satisfaction, compared with fixed orthodontics.
