Orthodontic attachment. The orthodontic attachment comprises a fixed base covered with a material which is heat-formable from 40 DEG C to 80 DEG C. The heat-formable base may be either aggregated to the base of the bracket, or be made in a moving envelope which fits over the base of the attachment and is self-adjusted by a hot-waterbath or using hot air. <IMAGE>
