Orthodontics

What is orthodontics?

Orthodontics is the use of mechanical devices to align teeth. These devices include braces, retainers, and newer technology such as Invisalign.

What is involved in orthodontic work?

For the most part, orthodontists divide their work into two phases: active and retention.

The active phase involves the use of braces or other corrective devices to physically pull the teeth into a new position. Braces are brackets that are mounted to the teeth, then connected with wires. The tension on various wires throughout the mouth is adjusted occasionally to make sure that each tooth is moving in its proper direction. Braces are usually left in place for between one and three years, though it can be longer. Recently, alternatives to braces that are less conspicuous and more convenient have been developed.

The retention phase involves the use of a retainer or similar device. The retainer does not pull on the teeth as braces do; instead, it merely holds them in position.

What is Invisalign?

Invisalign is a set of custom, clear plastic molds that provide an alternative to braces for straightening teeth. They are created based upon computer-generated maps of the patient’s teeth and projections of them in their new positions. The internal design of the first mold is just slightly different than the position of the teeth; when the mold is worn consistently, the teeth conform to the mold’s new position for them. The first mold is worn for a few weeks – all day and night, except when eating. After two weeks, the first mold is discarded in favor of the second; two weeks later, the second is thrown away and use of the third begins. This continues until the entire series has been completed. A set of invisalign molds typically consists of between eighteen and thirty molds. Invisalign molds are considerably less conspicuous than braces, making them the perfect alternative for adults in many walks of life.
