Duration Of Levelling And Aligning For Different Malocclusions In Patients Reporting For Orthodontic Treatment

The aim of this study is to assess the duration of levelling and aligning for different malocclusions in patients reporting for orthodontic treatment. The purpose of the study was to determine the duration of levelling and aligning during the orthodontic treatment of class I, class II and class III malocclusion. A hospital based cross- sectional study was conducted. 2100 patients who reported to the orthodontic department of the institution from June 2019 to April 2020 were screened. The inclusion criteria was patients with orthodontic treatment in the levelling aligning stage, young adults, no previous history of orthodontic treatment and only conventional metal brackets with 0.022 MBT prescription. 100 patients with Class I malocclusion, 100 patients with Class II malocclusion and 100 patients with Class III malocclusion were included in the study. The duration of levelling and aligning for each patient was retrieved retrospectively from the stored logs of the digital archives of our institution. Individual tooth abnormalities were also recorded for each patient.One way analysis of variance was performed to compare the difference between the two groups. Results showed that the total sample had a mean duration of 3.55±1.668 months for levelling and aligning which was longer in patients with Class II and class III malocclusion compared to Class I malocclusion. Within the limits of the study, patients with Class I malocclusions usually complete their treatments faster than Class II and Class III patients with Class III and class II div 1 subdivision patients taking the longest time to complete their treatment.
