Orthodontics is a branch of dentistry concerned with diagnosing, correcting, and preventing irregularities of the teeth(malocclusion) or poor occlusion, disproportionate jaw relationships.
Orthodontics includes dentofacial orthopedics, which is used to correct problems involving the growth of the jaw. Orthodontic treatment for
purely aesthetic reasons with regards to improving the general appearance of patient’s teeth. Orthodontists usually use braces and retainers to set your teeth. Additional components—including removable appliances (“plates”), headgear, expansion appliances, and many other devices—may also be used to move teeth and jaw bones.
After a course of active orthodontic treatment, patients have to wear retainers, which maintain the teeth in their improved positions while surrounding bone reforms around them. The retainers are generally worn full-time for a short period, perhaps six months to a year, then part-time (typically, nightly during sleep) for as long as the orthodontist recommends.
