Rapid palatal expansion device
TLDR
In this paper, an orthodontic rapid palatal expansion (RPE) device is described, which includes dual body members and four guide rods for increased stability and an increased range of palatal expand.Abstract:
An orthodontic rapid palatal expansion (RPE) device is disclosed which includes dual body members and four guide rods for increased stability and an increased range of palatal expansion. A jack screw threadably engages each body member and, upon rotation, generates an expansive force which is applied to the palate via the guide rods. A jack screw actuating head with multiple actuating apertures provides the means for rotating the jack screw, and a locking mechanism is included for the dual purposes of (1) preventing unwanted negative rotation or unwinding of the jack screw and (2) providing sensible indications of the positive rotation of the jack screw. Each guide rod is attached to a tooth by means of an attachment sleeve which allows for removal and replacement of the RPE device without removing molar bands secured to the teeth.read more
