Objective: The aim of this study was to compare the effect of different fixed lingual retainers (LRs) on tooth stability after orthodontic treatment using a Periotest® device. Materials and methods: A total of 82 patients (43 females and 39 males; mean age = 18.61 ± 3.71 years) with no missing teeth in the lower inter-canine region were treated with fixed orthodontic mechanics. At the completion of the orthodontic treatment, each patient was fitted with either Ortho FlexTech (Reliance; Group I), dead soft 8-braided (Bond-A-Braid, Reliance; Group II), or 5-stranded (PentaOne, Masel; Group III) LR wire. A control group consisting of people with a healthy periodontal condition and no bone loss was included (Control; Group C). The mobility of the lower anterior teeth on the right and left sides was measured using a Periotest® device before (T0), immediately after (T1), and 10 months after (T2) the application of the LR. Statistical analyses were performed using one-way ANOVA followed by post hoc LSD, repeated ANOVA with Bonferroni post hoc test, and Pearson χ2 tests.
Study Type
OBSERVATIONAL
The tooth mobility was determined by taking three repeat measurements from each tooth and calculating the average of these measurements, using a Periotest® device.
