Introduction to different types of fixed brackets in orthodontics

metal brackets

Metal brackets are orthodontic brackets that are bonded to the cheek side of the teeth through adhesives, and the teeth are corrected by exerting force through the corrective arch wire and the orthodontic brackets on the teeth. Patients cannot remove these brackets on their own. Currently, the most widely used metal brackets in the world are straightwire appliances. Because they are used by the most doctors and have the widest application, they have complete correction functions in all aspects.

self-ligating brackets

Self-ligating brackets are buccal fixed brackets. Compared with traditional non-self-ligating brackets, they can significantly reduce the discomfort during orthodontic treatment, extend the time between follow-up visits, shorten the time for intraoral operations during treatment, and more Easy to clean and maintain oral hygiene. In addition, self-ligating brackets can reduce resistance when teeth move and help teeth level and align faster. Various brands of self-locking designs on the market have different designs. Double-clip self-locking brackets also have a unique automatic protection function. When the orthodontic force is too strong, it can automatically release the archwire to avoid tooth damage and root apex resorption, thus making it more durable. Good protection of tooth and periodontal health. Self-ligating brackets are divided into two materials: metal and ceramic, both of which have the above characteristics. The color of ceramic self-ligating brackets is very close to the teeth and is more beautiful than metal self-ligating brackets.

ceramic brackets

Because the color of ceramic materials is close to the color of natural teeth, it sticks to the teeth well and is invisible, allowing the correction process to be completed quietly. Therefore, it is deeply loved by adults and patients with high aesthetic requirements, and has become one of the indispensable materials for orthodontic treatment. However, the strength of ceramic materials is weak and can easily break during treatment or removal, affecting the treatment results. Moreover, the color can easily lead to staining and discoloration due to poor oral hygiene maintenance habits of patients, which was once a major problem. But with the birth of a new generation of microcrystalline ceramic materials, these previous defects have now been overcome. Under the premise of ensuring the overall strength, today's high-end ceramic bracket materials are smaller in size and higher in strength. They also have the advantages of being resistant to staining, discoloration, and easy removal.

Lingual invisible bracket

Lingual invisible braces technology is a relatively advanced orthodontic technology that has emerged in the world in recent years. It installs all brackets on the lingual side of the teeth for orthodontic treatment, and no traces of orthodontics are visible on the outside. 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 established its own system and is widely used in Japan and the United States. Lingual invisible correction technology is relatively mature in countries such as Europe, the United States and Japan. It has high requirements for doctors to operate and is technically difficult.

Invisible brackets without brackets

Bracketless invisible brackets are a technology that uses 3D computer technology to customize a series of transparent dental trays to complete the entire orthodontic treatment. Compared with traditional orthodontic methods, bracketless invisible braces can be worn freely, so they have obvious advantages in oral hygiene, comfort and aesthetics. However, bracketless invisible braces require a high degree of cooperation from the patient (the daily wearing time needs to be greater than 22 hours), if it cannot be worn according to the time requirements, the treatment course will be extended and the efficacy will be greatly reduced. Therefore, there is still a certain gap compared with fixed appliances in terms of treatment results and application range of treatment indications.
