ABSTRACT:
An orthodontic bracket is provided including a plastic bracket body and a metal reinforcement member partly embedded in the bracket body. The bracket body includes a slot extending substantially along a mesial-distal axis of the bracket body for receiving an arch wire. The reinforcement member includes a holding notch having a width that is smaller than that of the slot of the bracket body. The holding notch is positioned inside the slot and spaced-apart from the slot surfaces to form an arch wire holding mechanism for engaging the arch wire and to substantially avoid contact between the arch wire and the surfaces of the slot. The bracket body may further include removable markings on the lingual and/or labial surfaces to facilitate positioning of the bracket.
