With the gradual increase in people’s love of beauty, more and more people want to say goodbye to the era of colored brackets, so the more popular invisible orthodontic treatment has generated great interest, but not all patients are suitable for this orthodontic technology, let me briefly discuss with you the mystery of invisible orthodontic treatment. Currently there are two main technologies in the world of invisible orthodontics, one is the lingual aligner, the other is the invisible aligner without brackets. I. Lingual braces Lingual braces, as the name implies, are braces installed on the lingual side of the teeth, not visible from the outside, this device was introduced, it was welcomed by adult patients, especially actors, models, lawyers, teachers, government civil servants and white-collar companies, but the lingual orthodontic technology today is the highest technical content, the most complex clinical operation, the highest treatment fees, (for three reasons, one is the lingual (for three reasons, one is that the lingual orthodontic appliances are completely imported orthodontic appliances, two is the lingual orthodontic appliances bonding process is complex, three is the doctor’s clinical operation time is long, technically difficult) for most patients, lingual orthodontic treatment takes 2 or more years to complete, and the general orthodontic treatment time is similar or slightly longer. So currently carried out in the country is not common, there are only a few hospitals in the country inside the individual doctors have this technology, so the publicity online or in the clinic lingual orthodontic technology is absolutely unreliable. Second, invisible brackets invisible orthodontic technology is the leading technology in invisible orthodontics, it is a change in the traditional orthodontic process “wire and iron teeth” situation, can be completed in the state of no wire, no brackets orthodontic treatment, so that others do not see you wearing braces, does not affect the aesthetics, can take off and wear, unknowingly restore the normal shape of teeth. This technology combines four advantages: aesthetics, comfort, convenience and cleanliness. Invisible bracketless orthodontics is the product of a perfect combination of modern computer-aided design, rapid prototyping technology and new materials. These transparent aligners are free of brackets and wires, and can be removed and worn unnoticeably, satisfying the need to correct teeth without compromising aesthetics. Especially worth mentioning is that the bracketless invisible orthodontic technology can carry out personalized design according to the jaw shape of the candidate, and each pair of aligners produced by computerized three-dimensional image technology simulates the movement of the teeth, and the teeth will feel the force after wearing them and move to the position designed by the aligners, usually replacing one pair of aligners every two weeks, the teeth will gradually move from the initial deformity to the normal alignment. The length of the orthodontic treatment depends on the severity of the patient’s malocclusion, and it usually takes six months to a year to solve problems such as misalignment of teeth. The advantages of invisible bracketless orthodontic technology 1, aesthetic: invisible, the next few people do not notice, can be lifted orthodontic teeth are an obstacle to the aesthetic concerns. 2, comfortable: less foreign body sensation, no oral mucosa stimulation. 3, convenient: can be removed by themselves, does not affect eating. 4, clean: you can take off the aligner and brush your teeth, oral hygiene is easy to maintain. 5, predictable: doctors and patients can see the simulated treatment process and results in advance before treatment, to better choose a personalized orthodontic program. Disadvantages: 1, the aligner is a removable removable aligner, the entire treatment course requires the replacement of up to 20 pairs of braces, relying on good patient cooperation, must be worn for more than 20 hours a day. 2, just wear orthodontic appliances on the pronunciation of a certain degree of impact. 3, can not solve the bony malocclusion. 4, relatively expensive, narrow indications. Main clinical indications: mild and moderate crowding (1-6mm). Mild and moderate gaps (1-6mm) without bony arch narrowing, or recurrent cases after fixed aligner treatment. Suitable for the correction of misalignment or mild torsion of individual teeth and for patients with poor periodontal health. Not suitable for cases with incomplete eruption, poor for cases of tooth extraction and cases requiring intermaxillary traction, cannot effectively control the overall movement and torque of the teeth, press in, and elongate the teeth with no obvious effect. In short, do not blindly worship invisible orthodontics.
