Title
(EN) ATTACHMENTS FOR TOOTH MOVEMENTS
(FR) ATTACHEMENTS POUR MOUVEMENTS DENTAIRES
Abstract
(EN)
Attachments for tooth movements are described herein where the orthodontic attachments may be formed by obtaining a digital model of a dentition of a subject and digitally placing one or more attachments upon the digital model for imparting one or more preselected movements to the dentition. A finite element model may be formed with one or more forces applied to the dentition and an initial stress map may be created to impart upon the dentition based on the finite element model. A subsequent stress map may be predicted using, e.g., machine learning, to achieve the one or more preselected movements.
(FR)
L'invention concerne des attachements pour mouvements dentaires, ces attachements orthodontiques pouvant être formés par obtention d'un modèle numérique d'une dentition d'un sujet et par positionnement numérique d'un ou de plusieurs attachements sur le modèle numérique en vue d'imprimer un ou plusieurs mouvements présélectionnés à la dentition. Un modèle en éléments finis peut être formé avec une ou plusieurs forces appliquées à la dentition et une carte de contraintes initiale peut être créée pour être appliquée à la dentition sur la base du modèle en éléments finis. Une carte de contraintes ultérieure peut être prédite à l'aide, par exemple, d'un apprentissage machine, pour obtenir le ou les mouvements présélectionnés.
