Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

For the purposes of this document, the terms and definitions given in ISO 1942 and the following apply.
3.1
angle of torque
θ
occlusal-gingival angle formed between the intersection of the line perpendicular to the tangent to the tooth
side surface of the base and the line bisecting the slot in the occlusal-gingival direction, when viewed along
the mesial-distal long-axis of the slot
NOTE If the angle is oriented toward the occlusal (gingival), it is designated as positive (negative).
See Figure 1.
3.2
angulation
α
angle between the line perpendicular to the mesial-distal long-axis of the slot and the central occlusal-gingival
axis of the bracket/tube, when viewed from the buccal/labial
NOTE The angulation is positive (negative) when the gingival part of the central occlusal-gingival axis is inclined
toward the distal (mesial) relative to the line perpendicular to the mesial-distal long-axis of the slot.
