Abstract : Aim: To assess the effect of Piezocision on post-orthodontic lower incisors stability as compared to fiberotomy and conventional Hawley retainers. Materials: 39 patients who just finished orthodontic treatment and had good quality orthodontic models (before and after treatment) were randomly divided into 3 groups; piezocision group (PG) (n=13), fiberotomy group (FG) (n=12) and a control group (CG) (n=14) (removable retainer). At debonding, lower anterior teeth were retained by fixed retainer (3-3) for 6 months in all the study groups. Piezocision and fiberotomy procedures were performed two weeks after debonding in the PG and FG respectively. Patients were then followed for another 6 months out of retention except for the control group. Lower Irregularity Index (IR) and Inter-canine width (ICW) were measured on models using digital caliper at three time periods; T1: pre-treatment, T2: 6-month post-retention, T3: 1-year post-retention. Data were analyzed and group comparison was conducted using Chi-square, One-way ANOVA and Post hoc tests. The significance level was set at p<0.05. Result: Groups were matched for age, gender, and T1: IR & ICW (p>0.05). Out of the 39 patients recruited, 1 patient in the PG discontinued treatment. Results showed that the IR increased from post-retention 6 months to one year for all groups; CG (-1.05±1.02), FG (-1.37±1.89) and PG (-0.52±0.72), while the ICW decreased in the CG (0.61±0.84), FG (0.24±0.38) and PG (0.44±1.15). No significant differences in IR & ICW changes were found between the three groups (p>0.05). Conclusion: Piezocision for post orthodontic retention is as effective as fiberotomy and removable retainer in the short term.
