Efficacy of fixed versus removal retianer post orthodontic treatment
A comparative study
Keywords:
orthodontics, fixed retainer, removable retainers, efficacyAbstract
The dearth of prolonged, prospective evaluation, the relative impact of fixed and the removable retainers eventualities can only be speculated upon. Hence in this study was to compare the stability of orthodontic outcomes with fixed and removable retainers over a period of at least 4 years. Of the 82 participants included in the previous RCT, data were obtained from 48 at 18-month follow up. Orthodontic stability was based chiefly on the irregularity of the mandibular incisors using Little’s Irregularity Index to assign a cumulative score for the contact point displacement in 4 the mandibular inter-canine region. Eighty-two participants were enrolled in the original RCT. After adjusting for confounders, the median between-groups difference was 1.64mm higher in those wearing vacuum-formed retainers (P= 0.02; 95% CI: 0.30, 2.98mm). No statistical difference was found between the treatment groups in terms of inter-canine (P= 0.52; 95% CI: -1.07, 0.55) and inter-molar widths (P= 0.55; 95% CI: -1.72, 0.93), arch length (P= 0.99; 95% CI: -1.15, 1.14) and extraction space opening (P= 0.84; 95% CI: -1.54, 1.86).
