How many kinds of orthodontic braces are there, which one is better?

Metal brackets: Ordinary metal brackets are traditional metal brackets and the cheapest orthodontic technology. Ceramic brackets: Ceramic brackets are a kind of brackets and a part of orthodontic appliances. Because its color is close to the real color of teeth, it is not easy to be detected after use, and it is also called invisible bracket. Ceramic brackets can meet the aesthetic requirements of patients, are durable and not easy to deform, and are ideal brackets for adult orthodontics. Compared with metal, the elastic modulus of ceramics is closer to that of teeth and is easy to be removed. Therefore, adolescent patients recommend the use of metal brackets. Ordinary ceramic brackets do not contain any metal components and are suitable for patients who are allergic to metals.

Single crystal transparent bracket: single crystal transparent bracket, commonly known as semi-invisible correction, is almost transparent and attached to the teeth, which has good concealment and can complete the correction process quietly. Self-locking bracket: Self-locking orthodontic bracket refers to a device which is made of metal or ceramic and fixed on the tooth surface with special adhesive in orthodontic treatment. It is used to contain and fix orthodontic steel wire and transmit orthodontic force to teeth, so as to achieve the purpose of orthodontics. Compared with the traditional bracket, the self-locking bracket has a locking device, just like adding a door to the bracket, which can directly lock the orthodontic steel wire in the groove of the bracket, avoiding the restraint of the ligating steel wire or rubber band on the orthodontic steel wire, greatly reducing the friction resistance between the steel wire and the bracket, reducing the stress on the teeth, accelerating the tooth movement speed and effectively shortening the whole treatment time.

Invisible orthodontics: Invisible orthodontics, also known as "invisible bracket-free orthodontics", is a kind of orthodontics. Invisible bracket-free orthodontics is widely favored by dentists because there are no steel wires and brackets in the traditional orthodontic process, which does not affect the appearance. Invisibility means that the computer designs multiple sets of braces with different processes according to the current arrangement and occlusal relationship of teeth. The whole design is very elaborate, which requires high instruments and technology, so it is also very comfortable and beautiful. However, invisible correction is generally only suitable for mild to moderate malocclusion and mild bony protrusion (but not recommended), and not all cases can achieve the best results.
