Orthodontic appliances such as orthodontic brackets are provided with bases (31, 56-58) that are shaped to correspond to the profiles of the specific teeth (e.g. 20, 35, 40, 44, 47) to which they are to be attached. The shapes of the bases (31, 56-58) facilitate the visual placement of the appliances on the teeth of patients by visually signaling to the practitioner the positioning of the appliance with the base thereof centered on the facial side of the tooth. This invention further facilitates the positioning of an archwire support (33, 51-54) of the appliance at a position on a tooth that is offset from the facial axis (FA) or from the center of the face of the tooth by manufacture of the appliance with the support offset from the center of the tooth-shaped pad. Preferably, the appliance base is a scaled reduction of the profile of the tooth, viewed from its facial side. The base is preferably scaled differently in the vertical and horizontal directions, with the shape of the base being reduced from that of the tooth profile by a greater amount vertically than horizontally. The tooth-shaped bases further facilitate identification of the specific tooth for which the appliance is intended.Des appareils orthodontiques tels que des brackets orthodontiques présentent des bases (31, 56-58) formées pour correspondre aux profils des dents spécifiques (par exemple 20, 35, 40, 44, 47) auxquels ils sont à fixer. Les formes des bases (31, 56-58) facilitent la mise en place visuelle des appareils sur les dents de patients par signalisation visuelle au praticien dentaire du positionnement de lappareil, sa base étant centrée sur le côté facial de la dent. Cette invention facilite davantage le positionnement dun support (33, 51-54) arqué en fil métallique de lappareil au niveau dune position sur la dent décalée de laxe facial (AF) ou du centre de la face de la dent par fabrication de lappareil avec le support décalé du centre de la plaquette se conformant à la dent.
