? According to dental implant experts, it is not as simple as some friends think, as long as you wear a braces. Orthodontists need professional orthodontists to work out the best orthodontic plan from the aspects of patients' tooth crowding, dental arch protrusion, facial shape, growth and development, genetic factors and so on. Braces and retainers should be worn for one and a half to three years. Before floor covering correction, the following tests should be done: (1) Dental impression: (that is, taking the mold) is used for doctors to diagnose the design right or wrong, and make a comparative examination in the future treatment process. (2) Photographing: Before treatment, the doctor should routinely take photos of the patient's face and occlusion for comparison with the end of treatment in the future. (3) X-ray examination: Each patient routinely took lateral cephalograms and panoramic radiographs. (4) Formulation of treatment plan: The doctor calculates the types of malocclusion according to the model, photos and X-rays, and formulates a detailed treatment plan. Then doctors explain various treatment schemes to patients and their families and ask for their opinions. After the treatment plan is determined, the patient or the patient's family will sign the consent form. Dental experts suggest that orthodontics is a highly professional discipline, and the qualification of orthodontists needs very strict examination and approval. Orthodontics is to apply proper "biological force" to teeth, alveolar bone and jaw with the help of appliance, so as to make them produce physiological movement, thus achieving the purpose of correcting tooth alignment deformity. Orthodontic treatment can not only correct teeth and improve facial deformity, but also prevent dental caries and periodontal diseases caused by irregular teeth, adjust the gap between missing teeth, treat temporomandibular joint dysfunction syndrome, and improve masticatory function and respiratory function.
