Correlation of the inclination of the incisors to the stability of the alignment of the anterior sector, based on PAR index criteria

Introduction: the objective of this study was to evaluate relationship between incisor inclination at end orthodontic treatment with anterior teeth alignment stability using PAR index. Methods: analytical cross-sectional study, angle formed plane (Silla-Nasion) (U1-NS) and upper axial lower mandibular (Go-Gn), were measured in 47 initial final lateral radiographs patients who finished treatment. The sector index applied pretreatment (T0), posttreatment (T1) follow-up (T2) casts. Statistical analysis performed frequency percentage distributions, T test, Anova I, II Manova; significance p = 0,05. Results: no association found inclination, weighted score T2-T1 (p> 0,05). decreased 75,29% from T0 T1 58,79% T2, a recurrence 16,5%. There retainer type score. From T2 there an interaction (p 0,03) 0,04), total Conclusion: modification sector. At high level correction anterior-superior inferior sector, however,
