With the improvement of living standards, people are pursuing more and more dental beauty. Generally speaking, the best time for orthodontic treatment is between the ages of 12 and 15. Many adult patients miss the best time for orthodontics for various reasons, many orthodontic devices on the surface of traditional braces – “steel braces” affect the health, aesthetics, career and social, so that many people who love beauty look “braces” but “teeth”. Invisalign technology has emerged to meet the need for aesthetic correction. Orthodontists have been working on aesthetic orthodontic technology, the development of invisible aligners has gone through the following stages: the seventies to Kurz as the representative of the traditional lingual aligners, the nineties to Invisalign as the representative of the invisible removable aligners without brackets, and in 2000 to Ingonito as the representative of the individualized lingual fixed aligners. Among them, lingual braces are the most effective braces for invisibility; and individualized lingual fixed braces are currently the most used lingual braces by physicians. Lingual braces bond orthodontic brackets to the lingual side of the teeth, which is completely invisible from the outside, truly beautiful and invisible, and protects the lip side of the teeth well, avoiding problems such as demineralization and discoloration caused by lip-side bonding brackets, and also enables direct observation of orthodontic results. Lingual braces also have disadvantages: high technical clinical complexity, high treatment costs, more difficult to popularize the use of the initial orthodontic pronunciation will have a slight impact on the patient’s adaptation period will be extended compared to traditional braces. Traditional lingual brackets are prefabricated, one set of brackets for all patients, due to the large variation in the morphology of the lingual side of the teeth, the interdental distance is narrow, the rate of loss is relatively high, the brackets fall off and re-bonding is not accurate, easy to pierce the tongue and impede pronunciation, making it difficult for doctors to control. The individualized lingual brackets are personalized with a computerized CAD/CAM system, thin and streamlined to overcome the influence of lingual side morphology variability, maximize the bracket spacing, increase the bracket base, and bond tightly, resulting in a low rate of bracket loss and more accurate placement of direct bonding or re-bonding after loss, significantly improving patient comfort. Because of the strong support of the CAD/CAM mechanic team, the clinical operation is simplified, the orthodontist’s operation is relatively simple, and the fine adjustment is relatively easier, which greatly improves the orthodontic effect. Traditional orthodontics, open mouth is “iron teeth”, the perfect combination of computer-aided three-dimensional diagnosis, personalized design and digital forming technology of invisible orthodontics – individualized lingual braces, to achieve the concealment of orthodontics and fast, in the correction of teeth at the same time also protect the patient’s privacy and social image, and thus by More and more dental seekers are looking at it.
