摘要：
The invention relates to a dental retraction device to be used for retracting the gingiva from a prepared tooth structure, the retraction device having the shape of a cord with a radial (x- and y-direction) and longitudinal direction (z-direction) and comprising an absorbing agent and optionally a retarding agent, wherein the retraction device is able to expand in the radial direction (x- and/or y-direction), but essentially does not expand in the longitudinal direction (z- -direction) upon contact with fluid.
