Claim:
A dental retainer apparatus for stabilization, so-called retention, of pairs of teeth or groups of teeth belonging to at least one of a lower jaw and an upper jaw during a retention period of orthodontic treatment, wherein the retainer apparatus comprises two individual retainer elements collectively forming a pair of such elements, said pair of retainer elements intended to cooperate through mutual contact when in position of use, in which position each retainer element is individually secured to a corresponding dental attachment surface of two adjacent teeth in a dental arch; wherein each individual retainer element comprises an outer surface, a basal surface and a retainer approximal surface; and wherein said retainer approximal surfaces are provided with complementary surface shapes to one another, thereby providing mutual contact surfaces that cooperate to stabilize one another when in position of use, hence also stabilizing the associated pair of teeth to which they are attached; and wherein said retainer approximal surfaces are provided with rough surfaces to enhance friction between said pair of retainer elements when in position of use.
