The invention relates to the medicine, in particularly, in orthodontics, and can be used during the correction of the form of upper jaw, namely, dental, alveolar and basal arches. The task of the group of inventions is to ensure increased functionalities of the devices for correction of the form of upper jaw, namely, dental alveolar and basal arches. The group of inventions has fastening elements, which are fastened on teeth of dentition's lateral segments and executed in the form of metal wireframes clasping teeth of dentition's lateral segments, and connected with two plates located on both sides of median palatine suture and connected with each other by the metal wire palatal power element or elements. In a first variant of the group of inventions, the plates are connected with the fastening elements through springs. The second and third variants of the group of inventions additionally have fastening elements, which are mounted on teeth of dentition's frontal segment and executed in the form of metal wireframe too. In the second variant of the group of inventions the plates are connected with fastening elements of lateral segments through springs, and a fastening element of frontal segment is connected with a metal wire palatal power element by springs. In a third variant of the group of inventions fastening elements are connected with each other and plates by a palatal arch through springs.
