Adult orthodontics: hospital selection is very important Adult orthodontic treatment is very different compared with adolescents, this is because adult growth and development has been completed, the jaw and facial bone gap has become bony fusion, plasticity is very low, and adult metabolic rate has become slower, biological reactivity is reduced, which increases the difficulty of orthodontic treatment. Compared with adolescents, adult orthodontics is more complicated, and adult malocclusion is often accompanied by other oral diseases, such as caries, periodontal disease, missing teeth, tooth wear, residual crowns, and residual roots. Before starting orthodontic treatment, comprehensive control of periodontal disease and removal of intra-oral restorations are required, otherwise the wear of aligners and movement of teeth will be affected. Since adult orthodontics is more complicated than children, adults who want to undergo orthodontic treatment must go to a regular hospital for a comprehensive oral examination, and the doctor will make a diagnosis based on the development of your jaws and teeth and choose an orthodontic method that suits you. Adult orthodontics: the choice of technology has to be careful. Many adult friends are eager to make their teeth more beautiful through orthodontics, but they are concerned about wearing braces for a longer period of time “steel teeth”. As a result, a variety of masking (i.e., undetectable during orthodontic treatment) orthodontic techniques have emerged. Once these techniques were introduced, they were warmly welcomed by the aesthetically or professionally demanding and special needs class of people such as entertainers, lawyers, teachers, civil servants, etc. Orthodontic techniques are usually divided into three types, each with its own advantages and disadvantages, and patients can choose according to their own situation. The first type of orthodontic treatment is orthodontic treatment in which the aligners are all placed on the lingual side of the teeth, also called lingual orthodontic technique. In this method, the aligners are not visible from the outside during orthodontic treatment and the patient can still perform a variety of special needs work and social activities. This type of orthodontic appliance is the most technically advanced, clinically complex and costly (more than $50,000) of current orthodontics, and the patient’s comfort level is poor, making it relatively narrow in clinical use. The second is the use of ceramic materials made into tooth-colored aligners, commonly known as ceramic brackets, because of its similarity to the color of the teeth, orthodontic only see a hidden filament, the aligner orthodontic efficiency is the highest, normal people think that it unknowingly changed the alignment of the teeth and change the facial image, so the most common clinical application, the cost of its orthodontic treatment in about 20,000 yuan. The third is the invisible orthodontic technology, which inherits the traditional concept of orthodontic treatment of malocclusion and is a perfect combination of modern dentistry, computer-aided three-dimensional diagnosis, personalized design and digital forming technology. It has the advantages of no brackets, aesthetic convenience, safety and comfort, cleanliness and hygiene, can be removed at any time and the number of patient visits is low, especially favored by white-collar people who love beauty. However, the orthodontic effectiveness is low, and only simple cases can be corrected, usually at a cost of about 20,000 yuan.
