During the period 1980s and 1990s great improvement in orthodontic technology was not seen. However, there were two improvements. Bonding materials were improved and the molar teeth can now be bonded instead of using the metal band. The elastic nickel titanium wire has gone super elastic. These super elastics wires can move teeth over a much longer period and they exert very light forces.
Since the beginning of 2000, there has been a tremendous change in orthodontic technology. It was a big leap forward. It began with the introduction of a completely new type of bracket.
These Self Ligating Brackets (e.g. Damon brackets) offers low force and low friction technology. With the combine use of these new brackets with super elastic nickel titanium wires and modern bonding materials, teeth can be moved much faster and with much reduced pain. Many cases where removal of teeth was once needed, they can now be treated without removal of teeth.
