Orthodontic retainer elements

A dental retainer device for stabilization, so-called retention, of pairs of teeth or groups of teeth in a lower jaw and/or an upper jaws in orthodontic treatment. The retainer device is formed of a pair of retainer elements, consisting of two preferably individual, but in the position of use cooperating, retainer elements. Each of the retainer elements is formed in with a retainer approximal surface, the retainer approximal surfaces being formed complementary relative to one another. In use, one or more pairs of retainer elements is/are positioned and secured with its/their individual elements preferably on the inner face of a tooth each of a pair of adjacent teeth, so that in the position of use the retainer approximal surfaces bear on each other and support, possibly lock, each other. Thereby pairs of teeth or groups of teeth are stabilized while it is possible at the same time to carry out normal dental hygiene by means of a toothbrush, dental floss or toothpicks, which is otherwise difficult to carry out when known retainers are used.
