发明名称 Dental bracket
摘要 The invention describes a dental bracket to be applied on the dental surface and having a retention base and two wings each of which is provided with a rectangular slot for accommodation of a dental arch wire. The slots are inclined relative to the retention base in order to be able to execute a corresponding torque upon the tooth. This inclination is achieved by a correspondingly oblique position of the retention base relative to the bracket wings. Furthermore, the slots are inclined relative to the lateral surfaces of the wings in such a way that a corresponding tilting moment (angulation) can be exerted upon the tooth. The periphery of the retention base is designed in rhombus shape such that the upper and lower peripheral edges of the retention base extend in parallel to the slots. The retention base and the two bracket wings are made in one piece. Moreover, the basic surface of the retention base is provided with an axial and circumferential knurl. These measures permit the dimensions of the dental bracket to be kept very small. <IMAGE>
