The aim of orthodontic treatment is to align the teeth and jaws, and balance them with the rest of the face to improve aethetics & function.
In the past the extraction of permanent teeth as a means of creating space to align teeth was common, however by utilising contemporary techniques and material for arch expansion, this is no longer necessary most of the time. The decision is now based on the facial profile rather than the need for space.
Computerised analysis of the facial skeleton is carried out prior to treatment to relate the size and position of the upper and lower jaw to each other, and to the skull base to determine ultimate results.
Orthodontic treatment can be carried out on children or adults, and treatment time is now shorter than ever before, again because of newer materials.
