Abstract: A device has a metal wireframe with two lateral fastening elements which are connected through metal lingual and vestibular springs to a frontal fastening element and executed in the form of metal wireframes clasping teeth of dentition's lateral segments and performed of lingual and vestibular details located at necks of teeth from the one side and dispersedly mounted along the height of teeth from the other side and connected by crosspieces.

Abstract: A method for correction of the form of dental alveolar arch relates to medicine and can be used in orthodontics for correction of the form of dental alveolar arch in the lingual and vestibular directions. The method intensifies correction of the form of alveolar process and increases convenience of the device usage. The method may be realized through fitting of an orthodontic device in the cavity of the mouth, its periodic removal and activation and influence on teeth by forward and rotary forces. In intervals between periodic activations through repeated removal of forces developed by the device, teeth are influenced by forces of masticatory muscles.

Abstract: The invention relates to medicine and could be used in orthodontics during the stimulation of growth and filling of defects of jaw's missing tissues, in particular, of palate cleft and alveolar process. According to a proposed method a defect is closed by a plate, edges of defect are irritated by imparting vibratory motions to a plate and a space is freed for neoformations of tissues by periodically correcting of a plate's working surface. A proposed device has fastening elements on teeth of lateral segments, a plate or plates closing missing tissues of defect and a lingual arch, which is connected to fastening elements and a plate or plates through springs. Fastening elements are realized in the form of metal wireframes, details of which clasping necks of lateral teeth from lingual and vestibular sides are connected by crosspieces disposed in interdental spaces, as well as, in intertubercular recesses of teeth in sagittal and/or transversal directions.
