Orthodontic apparatus

An orthodontic apparatus comprising a biasing device, the biasing device being configured to bias the apparatus in a contracted configuration, the biasing device comprising:

• a first anchor configured for connecting to a first attachment member or to a first location within a patient's mouth at a distal end thereof, wherein the first anchor has a first or proximal portion including a proximal end and a second or distal portion including a distal end;
• a second anchor configured for connecting to a second attachment member or to a second location within a patient's mouth at a distal end thereof, wherein the first anchor has a first or proximal portion including a proximal end and a second or distal portion including a distal end;
• and
• a biasing member provided between the proximal end of the first anchor and the proximal end of the second anchor such that the first or proximal portion of the first anchor and the first or proximal portion of the second anchor overlap,
• wherein the first or proximal portion of the first anchor extends in a first, longitudinal, direction at least when the biasing device is in a relaxed or contracted configuration and the first or proximal portion of the second anchor extend in a third, longitudinal, direction at least when the biasing device is in a relaxed or contracted configuration,
• wherein the second or distal portion of the first anchor is substantially planar and extends in a second plane and in a second direction which is different from the first longitudinal direction of its respective first or proximal portion, and wherein the second or distal portion of the second anchor is substantially planar and extends in a fourth plane and in a fourth direction which is different from the third longitudinal direction of its respective first or proximal portion,
• and wherein the second plane is different from the fourth plane.
