<p>The orthodontic bracket (10) comprises a bracket base (12) that is curved in the mesial-distal direction attachment surface (14) for attachment of the bracket to a tooth. The bracket main portion (16) is formed with a mesial-distal extending slot. A slot base (28) is adapted for receiving an archwire. The slot base is formed with curvature in the mesial-distal direction such that the radius of curvature is greater than that of the attachment surface.</p> |
