The comprehensive treatment of malocclusion usually starts from the permanent tooth stage, and the course of treatment is long (1~2 years). The correction process is complex, and there are many factors that affect the treatment effect. To achieve good therapeutic effect, at least the following points should be achieved. First, we should choose orthodontists with rich professional knowledge and excellent clinical correction skills. To correct teeth, orthodontists should first make a detailed examination, find out the existing problems, and make a correct diagnosis, design and reasonable correction plan through comprehensive analysis, which requires orthodontists to have rich professional theoretical knowledge and certain clinical experience; The next step is the specific treatment process, that is, the process of implementing the correction plan, which requires orthodontists to have excellent correction technology in order to successfully complete and achieve the predetermined treatment effect. Orthodontists should not only have the ability to observe and find problems, but also have the ability to solve problems in clinical practice. Therefore, orthodontic patients should first choose an orthodontist to correct themselves. Second, patients should actively cooperate with the treatment. During orthodontics, the appliance parts should be bonded to the teeth, and some auxiliary devices should be worn (the patient takes them off by himself). This requires patients to maintain good oral hygiene and avoid periodontal disease; Pay attention to diet, don't eat anything too sticky and hard, and don't chew with front teeth to prevent the appliance parts from falling off or being damaged; Wear auxiliary devices according to the requirements of orthodontists. Only with the good cooperation of orthodontists can the correction be carried out smoothly and achieve good results; Otherwise, no matter how well orthodontists do, they will not achieve good treatment results. Third, choose the right electrical appliances. Orthodontics is an instrument used by doctors to correct teeth, and there are many kinds used in clinic now. There are domestic and imported products, among which there are many kinds according to their different materials, structures and some properties. Each has its own characteristics, of course, the price varies greatly. In fact, the appliance is just a tool, and orthodontists use it to correct teeth. The quality of treatment is not the key factor, but the application ability of orthodontists. As long as the orthodontist's correction technique is good, the general appliance can still achieve good therapeutic effect; If the orthodontist's skill is not up to standard, no matter how good the appliance is, it can't be done well. Of course, for the same orthodontist, the better the appliance used, the smoother the operation, the smoother the correction process and the better the correction effect. Patients can choose the appropriate orthosis according to their own situation. Those with poor economic conditions can be made in China, and those with good economic conditions can be imported or have better performance. In short, as long as orthodontic patients choose qualified orthodontists, use appropriate orthodontic appliances and actively cooperate with themselves, they can obtain satisfactory orthodontic results.
