A typical Orthodontic treatment , takes 6-24 months. The treatment time depends on the movements the teeth need to undergo.
In straight-wire treatment the orthodontist
bonds braces on the teeth and aligns them with a special spring. As the
treatment advances the orthodontist changes the wire from flexible to
more rigid, finally aligning the teeth to a very firm arch form. In many cases it is required to make fine tuning and adjustments at
the end of the treatment by using wire bending or changing the location
of braces (re-bonding). The main need for corrections is caused by the
way the treatment is planned - the orthodontist can see the start of
the treatment but not the end. It is possible to speed up the treatment using a computer system
that allows to plan the treatment objective by looking at teeth
geometry both at the beginning and at the end of the treatment. This
way the location of the braces is determined by the final location of
each tooth. In many cases such a design leads to a treatment that
advances to the objective smoother, faster with less re-bracketing or
bending. Another important factor that can help is accurate selection of appliances.
