Abstract

Objective: The study aimed to clarify (1) the effect of the Beneslider distalization appliance on maxillary molars (M1+2), (2) the type of tooth movement, and (3) changes in skeletal parameters.<br />Study Design: Dental distalization paths and transversal changes were measured according to the distance of the pterygoid vertical as well as on the virtualized 3D plaster model.<br />Results: Distalization of the second premolar (P2; T1 - T2) was 2.51 mm (±1.81 mm; P < .001) combined with a distal tipping of 6.50° (±5.09°; P < .001), whereas for M1 a distalization of 3.49 mm (±1.10 mm) occurred with negligible tipping (0.73° ± 5.04°). No significant differences (T1 - T2) on sagittal and vertical skeletal variables were found within or between G1+2. In contrast, a significant increase in N-Sp' in G2 and in Sp'-Gn in G1+2 with consecutive Hasund index reduction was shown. Comparing T1 and T2, the device had an effect on the transversal development.<br />Conclusion: The Beneslider distalization appliance causes an effective distalization of M1+2, with slight second premolar tipping. No modification of skeletal parameters was recorded, but a relevant effect on Hasund index and the transverse was found.<br /> (Copyright © 2021 Elsevier Inc. All rights reserved.)
