摘要：
System for repositioning teeth from one arrangement of teeth to another arrangement of teeth, said system comprising a set of incremental position adjustment devices (100) comprising housings having cavities configured to receive and reposition teeth, the devices being designed to cause that the teeth move incrementally from one arrangement of teeth to another arrangement of teeth when the devices are carried in succession by a patient, in which the stiffness of at least some of the devices are non-uniform in the device and the rigidities of geometrically corresponding parts of the housing of at least two of said devices differ from each other, and in which the housings of said at least two of said set of devices have the same shape, the devices consisting of a thermoformable material that it is thermoformed to produce the apparatus； wherein at least one of said devices has a first and a second housing part of different stiffness； in which the first and the second housing part are each configured to receive one or more teeth； the at least one apparatus comprising layers of different stiffnesses； wherein the at least one apparatus comprises a discontinuous inner layer and a continuous outer layer, at least a part of the inner layer being configured to engage individual teeth or groups of teeth and being more rigid than the outer layer.Sistema para reposicionar dientes desde una disposición de dientes a otra disposición de dientes, comprendiendo dicho sistema un conjunto de aparatos ajuste de posición incremental (100) que comprende unas carcasas que presentan unas cavidades configuradas para recibir y reposicionar dientes, estando diseñados los aparatos para provocar que los dientes se muevan de manera incremental de una disposición de dientes a otra disposición de dientes cuando los aparatos se llevan en sucesión por un paciente, en el que la rigidez de por lo menos algunos de los aparatos son no uniformes en el aparato y las rigideces de partes de la carcasa geomét
