| Description | Aims: Assessment of the effectiveness of distalization with skeletally anchored appliance Beneslider related to eruption of maxillary permanent second molars. Material and method: The retrospective study of 30 patients evaluated distalization of molars with Beneslider appliance adapted for the orthodontic therapy. Cephalograms taken prior to orthodontic therapy and after distalization of maxillary permanent first molars, first and second premolars, were evaluated. The patients were divided into two groups. Group A included 14 patients without erupted maxillary permanent second molars prior to the appliance adjustment. Group B included 16 patients with erupted maxillary permanent second molars. Results: In both groups first molars were successfully distalized. In Group A the mean distalization at the crown level was 3.56+ 0.75 mm, at the root level 3.62+1.37 mm. In Group B the mean distalization at the crown level was 4.6+1.46 mm, at the root level 4.41+1.59 mm. During the process of distalization the inclination of molar was not statistically significant in either group, the change in SNGoMe angle was not statistically significant either. Conclusion: Beneslider appliance is an effective tool for the distalization of maxillary permanent first molars with bodily movement, even in cases where maxillary second molars are erupted. |
