Beauty is of the times, from the fat and thin to the unisex beauty, people’s standard of beauty has always been influenced by various factors and changes. However, no matter how times change, no matter how men or women, and no matter how Eastern or Western, people’s pursuit of neatly aligned teeth has never ceased. However, with the change of time, our living environment and diet are changing, and “soft, sticky and sweet” foods are becoming more and more important in our daily diet, so various dental problems are coming to the fore. Malocclusion is one of them, which not only affects people’s appearance and health, but also has a negative impact on social life and career choice, causing low self-esteem and even psychological disorders. For this reason, many students and some white-collar workers go to dental hospitals to consult orthodontic treatment, looking for the possibility of making the “defect” into “perfect”. However, beauty always comes with a price. When it comes to making misaligned teeth become neat and healthy, many people will naturally think of others in the orthodontic “steel teeth” look. As a rule, orthodontic braces are applied to the teeth, i.e., brackets are bonded to the teeth, and then the archwire is used to move the teeth to achieve orthodontic purposes. Although the orthodontic treatment can be aesthetically pleasing, it is a major aesthetic challenge to wear braces during the years of orthodontic treatment; at the same time, the wearing of braces will also affect the patient’s diet and oral hygiene to a certain extent, which discourages many patients, especially adult patients. Patient demand is the motivation for doctors to move forward, and smart dentists developed the Invisalign technology in 1997, called “Invisalign”, which means “making teeth straight and invisible”. The technology was first created in the United States, and by the end of 2009, more than 1.3 million patients worldwide had opted for the technology, but it was expensive abroad. In order to make this technology beneficial to our countrymen, our physicians have also successfully developed this technology, which was officially promoted in the clinical application in 2004. Invisible bracketless orthodontics is a new high-tech product based on computer-aided three-dimensional diagnosis, personalized orthodontic design, and the production of bracketless invisible aligners for patients with malocclusion. It has the advantages of aesthetics, comfort, convenience, speed, cleanliness, and predictable results. It uses invisible aligners made of transparent elastic medical polymer material, no brackets and wires, social distance can not be detected; aligners are smooth and comfortable to wear, no obvious foreign body sensation, less stimulation to the oral mucosa, and can be removed by themselves, easy to care for oral hygiene; and can be visualized before treatment to simulate the changes in the entire treatment process, patients can directly see the changes in their teeth, preview Patients can directly see the changes in their teeth and preview the final orthodontic effect in order to better choose a personalized orthodontic solution. Because the entire orthodontic process can be simulated and the entire aligner processed, remote orthodontic treatment can be implemented for some patients who have difficulty with normal follow-up visits. Therefore, although traditional fixed aligners have remained the mainstream technology for quite some time, bracketless invisible orthodontics is becoming one of the hot spots in the development of orthodontic technology based on its high-tech, aesthetic and comfortable features. Over the years, our orthodontic department has initiated the application of bracketless invisible orthodontic technology, which has become increasingly popular among adult patients. We look forward to, with our joint efforts, making more people’s teeth straight and invisible.
