A bar clip attachment that allows free movement of the prosthesis. Its applications are for overdentures and implant prosthetics. The principle feature of the Ackermann Clip is that the bar may be adjusted to follow not only the vertical contours of the mucosa, but also the anterior-posterior curvature of the edentulous ridge. The spacer provides for both vertical and rotational free movement of the prosthesis. The clip is fully adjustable and easy to insert and remove.

Wide field of applications, as the bar may be bent in all directions allowing it to exactly follow the contours of the ridge.

The Ackermann may be used for square or curved arches.

Due to its short 3.6mm length, the sleeve may be positioned on the bar even in a deep narrow trough.
