Abstract

La présente invention concerne la correction de la forme de l'arc alvéolaire des dents ou la forme de la mâchoire supérieure et la stimulation de la croissante et le comblement des défauts des tissus maxillaires manquants. Un bâti filaire métallique est monté sur les dents du segment frontal de la dentition, des éléments de fixation étant reliés au travers de l'arc lingual ou des éléments moteurs linguaux et vestibulaires. Selon un autre mode de réalisation, les éléments de fixation ont montés sur les dents des segments latéraux de la dentition, notamment des bâtis en fil métallique pinçant les dents des segments latéraux de la dentition, et reliés à deux plaques situées des deux côtés de la suture palatine médiane et reliés entre eux par des éléments moteurs palataux en fil métallique. Les éléments de fixation sur les dents des segments latéraux et une plaque ou des plaques peuvent être reliés par des ressorts. Les bords des défauts maxillaires peuvent être irrités par les vibrations affectant une plaque. Il est possible de ménager de l'espace libre pour les néoformations tissulaires par une correction périodique d'une surface active de la plaque. La forme de l'arc alvéolaire peut se corriger par l'adaptation d'un dispositif orthodontique dans la cavité buccale, ses retraits et mise en place périodiques, et l'influence sur les dents par des forces postéro-antérieures et rotatives.
