As people’s standard of living improves, the demand for beauty also rises, and more and more patients are now actively consulting on invisible orthodontic treatment. Now there are three main types of orthodontic treatment with invisible effects commonly used in clinical practice, including ceramic brackets, invisalign and Time Angel clear invisible aligners, as well as lingual orthodontics. Each of them has its own advantages and disadvantages, as well as the scope of application. Strictly speaking, ceramic brackets, i.e., the color of the brackets and the color of the teeth are similar, it is not considered an invisible aligner, it only has a certain invisible visual effect. Invisalign is designed by Align Technology in the United States and Era Angel is produced by a domestic company, they are basically based on the same principle. They are removable aligners that are transparent and wrapped around the surface of the teeth, and can be removed during diet and special moments. The comfort of these invisible aligners has a clear advantage over the others. However, the cost of invisalign is usually two to three times higher than the cost of regular orthodontic treatment. The domestic Era Angel clear aligners have some advantages over invisalign in terms of cost. Finally, we talk about lingual orthodontics, an invisible method with higher requirements for orthodontic technology, where all orthodontic devices are on the lingual side and the invisible effect is the best, but the comfort level is different for different patients, usually within an acceptable range and requires some adaptation time. Also the cost of lingual orthodontics is higher. To sum up, everything in the world does not have all the advantages and disadvantages of existence, different invisible orthodontic methods have their different advantages and limitations. The choice of orthodontic treatment requires a professional orthodontist to provide professional advice to different patients after a careful clinical examination and understanding of the patient’s requirements.
