An orthodontic device comprises a dental plate from plastic or the like adapted to be fitted to the jaw. One or more wire clamps may be fixed to the dental plate along its side edges and destined to be positioned around and/or between at least a number of molar teeth. An anchor is fixed to the dental plate along its front edge and destined to grip in fitting relation around at least a number of teeth. The anchor is formed from colorless transparent plastic that is connected integrally to the dental plate and fits closely against the front and rear side of all of the teeth of the jaw. At least the cutting faces of the incisors project freely through the anchor.
