Orthodontic treatment is a series of processes to move poorly aligned teeth to a desirable position. Orthodontic treatment can improve the appearance, the biting position and chewing function. Orthodontic procedures includes placement of orthodontic brackets. The orthodontic wire and orthodontic brackets are connected by elastics and stainless steel wires or ligatures. Regular dental visits may be required as suggested by the orthodontist. After the teeth, has moved to a favourable position, a retainer is used to hold and stabilize the teeth in these positions. The overall duration lasts for about 1.5 to 3 years. The actual time needed depends on the complexity of the treatment. The orthodontic appliances can be fixed or removable. In case of removable orthodontic appliances, impressions of the teeth are taken first and then the removable orthodontic appliance is fabricated in the dental laboratory. Later, the appliance is fitted in the mouth, and activated the springs or screw. Orthodontic treatment can be done by many sorts of appliances, which most people call a 'brace'. Simple treatment may be carried out with a removable brace (a plate that can be taken out to be cleaned). It has delicate wires and springs attached, which move the teeth using gentle pressure. The length of treatment depends on how severe the problem is, and it may take anything from a few months to two-and-a-half years. Most people can be treated in one to two years. Orthodontic braces usually need adjusting every 4 to 6 weeks. One's orthodontist will tell how often one's brace will need adjusting.
