Introduction- The purpose of this prospective study was to compare the aligning efficiency of two modalities- clear aligner therapy and fixed appliance using nickel titanium wires, in the lower anterior region.
Method- The sample included 20 patients who had mild to moderate crowding were selected, and randomly divided into two groups-Aligner group & NiTi group. Records were taken at 4 week intervals till 12 weeks in both the groups. The crowding was measured at all stages using the Little’s irregularity index using a caliper and then summed up to give the total irregularity score
Result- The result of this study showed that over a fixed time the Mean for Little’s Irregularity Index scores was compared using Repeated measures of Anova and this difference was found to be statistically significant for both the groups. The maximum change in the score was observed between zero to four weeks of treatment for both modalities.
Conclusion- The results of this study indicate that both clear aligners and conventional fixed therapy are effective in the resolution of lower anterior crowding. However, when the two groups are compared, the differences found were not statistically significant. This indicates that clear aligner therapy is an effective treatment modality for mild to moderate malocclusions.
