Title (EN) MODULAR SYSTEM FOR CUSTOMIZED ORTHODONTIC APPLIANCES
(FR) SYSTEME MODULAIRE POUR APPAREILS ORTHODONTIQUES SUR MESURES
Abstract:
(EN) A set of customized orthodontic brackets (14) are provided with slots (22) that are arranged substantially parallel to the tooth surface. The archwire (10), in an as−manufactured condition, has a portion of substantial arcuate extent, which is canted relative to the occlusal plane (15). The brackets (14) are designed on a computer as a combination of three−dimensional virtual objects comprising the virtual bracket bonding pad (18) and a separate virtual bracket body retrieved from a library of virtual bracket bodies. The virtual brackets can be represented as a file containing digital shape data and exported to a rapid prototype fabrication device for fabrication of the bracket (14) in wax or other material and casting the wax prototype in a suitable alloy. Other manufacturing techniques are also contemplated, including milling and laser sintering.
(FR) L'invention concerne une série de crochets orthodontiques sur mesure (14) comportant des fentes (22) agencés sensiblement parallèle à la surface de la dent. Le fil de l'arc (10), de fabrication standard, possède une portion d'étendue sensiblement arquée, qui est inclinée par rapport au plan d'occlusion (15). Les crochets (14) sont conçus sur ordinateur en tant que combinaison d'objets virtuels tridimensionnels comprenant la plaque de liaison du crochet virtuel (18) et un corps de crochet virtuel séparé récupéré dans une banque de corps de crochets virtuels. Les crochets virtuels peuvent être représentés sous forme de fichier contenant des données numériques de forme et exportées sur un dispositif de fabrication rapide de prototype destiné à fabriquer le crochet (14) en cire ou en autre matériau et à mouler le prototype de cire dans un alliage adapté. L'invention concerne aussi d'autres techniques de fabrication incluant le broyage et le frittage par laser.
