Orthodontic methods of orthodontics

With the improvement of dental technology and patients' aesthetic requirements for orthodontic treatment, orthodontic treatment has gradually developed a variety of orthodontic materials and methods from movable brackets and buccal fixed brackets, such as ceramic brackets, self-locking brackets, lingual invisible brackets and bracketless invisible brackets. According to the requirements of different doctors and patients for curative effect, beauty and comfort, more treatment schemes are provided. Metal bracket

Metal bracket refers to the orthodontic bracket adhered to the buccal side of the tooth by adhesive, and then the force is applied between the orthodontic archwire and the orthodontic bracket on the tooth to correct the tooth. This kind of stent can't be removed by the patient himself. At present, the most widely used metal bracket in the world is straight wire appliance. Because it is used most by doctors and widely used, the orthodontic function in all aspects is relatively perfect.

Self-locking bracket

Self-locking bracket is the most advanced buccal fixed bracket at present. Compared with traditional non-self-locking brackets, it can obviously reduce the discomfort during orthodontic treatment, prolong the follow-up interval, shorten the time of oral surgery, and make it easier to clean and maintain oral hygiene. In addition, the self-locking bracket can also reduce the resistance when the teeth move and help the teeth to be leveled and aligned more quickly. The self-locking design of various brands on the market is different. Double-clip self-ligating brackets also have a special automatic protection function, which can automatically release the archwire when the orthodontic force is too large to avoid tooth damage and root tip absorption, thus better protecting the health of teeth and periodontal. Self-locking brackets are divided into metal and ceramic materials, both of which have the above characteristics. The color of ceramic self-locking is very close to the color of teeth, which is more beautiful than metal self-locking brackets.

Ceramic bracket

Because the color of ceramic material is close to the color of natural teeth, it has good concealment to stick to teeth, which makes the orthodontic process quietly completed. Therefore, it is deeply loved by adults and patients with high aesthetic requirements and becomes one of the indispensable materials for orthodontic treatment. However, the strength of ceramic materials is weak, and it is easy to break during treatment or removal, which affects the therapeutic effect. And the color is easy to be dyed and discolored because of the patient's bad oral hygiene maintenance habits, which used to be its main problem. But with the birth of a new generation of microcrystalline ceramic materials, these defects have been overcome now. On the premise of ensuring the overall strength, today's high-end ceramic bracket materials are smaller in size, higher in strength, and have the advantages of being difficult to dye, discolor and remove.

Lingual invisible bracket is an advanced orthodontic technique in the world in recent years. It is to install all brackets on the lingual side of the teeth for orthodontic treatment, and there is no orthodontic trace on the appearance. Lingual correction technology began to appear in Japan and the United States as early as the 1970s. After years of theoretical research and technical improvement, it has become a self-contained system and has been widely used in Japan and the United States. The technology of invisible tongue correction is relatively mature in Europe, America, Japan and other countries, which requires higher operation for doctors and is technically difficult.

Non-stent invisible stent

The invisible bracket without bracket is a technology that uses 3D computer technology to tailor a series of transparent trays to complete the whole orthodontic treatment. Compared with traditional orthodontics, bracketless invisible orthodontics can be disassembled freely, so it has obvious advantages in oral cleanliness, comfort and aesthetics. However, bracket-free invisible orthodontics requires a higher degree of cooperation for patients (wearing time should be more than 22 hours a day). If you can't wear it according to the time requirement, the course of treatment will be prolonged and the curative effect will be greatly reduced. Therefore, there is still a certain gap between the fixed appliance and the fixed appliance in the treatment effect and the application scope of the treatment indications.
