Title (EN) HYBRID ORTHODONTIC ARCHWIRE
(FR) ARC ORTHODONTIQUE HYBRIDE
Abstract:
(EN) An archwire used during the course of orthodontic treatment has four generally flat sides that are arranged in the general shape of a rectangle. The four sides are connected by curved surfaces having a radius of curvature that is substantially larger than the corners of conventional archwires. The cross-sectional shape of the archwire facilitates insertion and removal of the archwire in orthodontic appliances such as brackets and also tends to reduce resistance to sliding movement of the appliances along the archwire.
(FR) L’invention concerne un arc utilisé dans le cadre d’un traitement orthodontique, comportant quatre côtés généralement plats disposés de manière à adopter la forme générale d’un rectangle. Les quatre côtés sont reliés par des surfaces incurvées dont le rayon de courbure est sensiblement plus grand que les coins des arcs traditionnels. L’arc de l’invention présente une section transversale qui en facilite l’insertion et le retrait dans des appareils orthodontiques tels que des bagues et qui tend à réduire la résistance de ces appareils au glissement le long de l’arc.
