Abstract: The invention relates to an orthodontic expansion screw having two bodies whose distance from each other can be changed by means of a spindle that engages both bodies, whereby the spindle comprises an actuation part by means of which a torque can be effected for readjusting the spindle, and having straight-line guiding means that engage both bodies and guide them along two guide axes that are parallel to each other while preventing a relative rotation of the bodies when their distance from each other is being changed. The invention provides a friction brake that presses onto the actuation part of the spindle and thus generates a frictional force that renders a rotation of the spindle in both directions of rotation more difficult in order to prevent inadvertent readjustment of the spindle.

Abstract: A device for relocating a lower jaw relative to an upper jaw. The device is telescopically extensible and is a kind of a Herbst hinge, including a holder with an eye mounted on each of its two ends. The device can be mounted in articulated fashion, for example on a molar strip in the upper jaw and on a molar strip in the lower jaw. The molar strip is usually provided for this purpose with a counter-holder with an internal thread into which a head screw can be screwed through the respective holder of the device, the articulated connection being realized by the fact that either the shaft of the head screw or a shaft engages the eye of the device so as to permit the latter to rotate about the respective shaft.

Abstract: The invention describes a composite palatal arch for the correction of the position of teeth, which is built up from a plurality of wire sections (1, 2, 3, 4, 5) made from different materials. One of the materials is a shape-memory alloy that assumes a superelastic state at the temperatures prevailing in a human mouth. The palatal arch comprises two end sections (2, 3), which are intended to fix the palatal arch in a tooth lock (16, 17) and which are made from of a normal-elastic material. The superelastic section (4, 5) of the arch is softer than are the normal-elastic sections (1, 2, 3). The superelastic material is present only in two intermediate sections (4, 5) between the two end sections (2, 3) and a central section (1), the two intermediate sections (4, 5) are each arranged adjacent one of the end sections (2, 3), and the central section (1) of the palatal arch consists of a normal-elastic material.
