Set of premanufactured positioners for the final treatment in the orthodontic and jaw orthopedic tooth alignment

摘要

A fine alignment apparatus for the final treatment in orthodontic and jaw orthopedic tooth alignment, a so-called "positioner", has tooth receiving cavities (1,2). These cavities are recessed at the portions thereof away from the area which receives the incisal edges (4) of the incisors and canines (3) and the cusp tips (6, 7) of the side teeth (8). Through this position changes of the teeth when the positioner is inserted, which are caused by anatomic variations of the teeth or for example fillings, are reliably prevented.
