Does molar distalization by the Beneslider have skeletal and dental impacts? A prospective 3D analysis.

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.

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.

Results: Distalization of the second premolar (P2; T1 - T2) was 2.

Development of a new device for maxillary molar distalization with high pseudoelastic forces to overcome slider friction: the Longslider--a modification of the Beneslider.

Objective: Skeletally anchored devices have been developed to distalize maxillary molars in class II malocclusion. NiTi springs with high pseudoelastic forces are required to overcome friction and concomitantly create ideal translation force for molar distalization. We present a new maxillary molar distalization device (the Longslider) generating forces of up to gf 600 (5.
