Comprehensive treatment of malocclusion usually starts from the permanent teeth stage, with a long course of treatment (1~2 years), a complicated corrective process and many factors affecting the treatment effect. In order to achieve good treatment results, the following points should be done at the very least. First, we should choose an orthodontic specialist who has rich professional knowledge and excellent clinical orthodontic technology. To correct the teeth, first of all orthodontist to do a detailed examination, find out the existence of the problem, after a comprehensive analysis, to make a correct diagnosis, design and reasonable orthodontic plan, which requires orthodontist has a wealth of professional theoretical knowledge and a certain amount of clinical experience; the next step is the specific treatment process, that is, the implementation of the process of orthodontic plan, which requires orthodontist has a good orthodontic skills to be able to Successful completion, to achieve the intended therapeutic effect. Orthodontists should not only have the ability to analyze and judge the observation and discovery of problems, but also have the clinical operation ability to solve problems. Therefore, orthodontic patients should first choose orthodontic professional doctors to do orthodontic treatment for themselves. Secondly, patients should actively cooperate with the treatment. During the period of orthodontic treatment, the orthodontic components should be bonded on the teeth, and some of them also need to wear some auxiliary devices (the patient himself removes and wears them). This requires patients to maintain good oral hygiene to avoid periodontal disease; diet should also pay attention to, do not eat too sticky, too hard things, do not use the front teeth to gnaw on things, in order to prevent the orthodontic components fall off or damage; according to the orthodontist’s requirements to wear a good auxiliary device. Only with good cooperation can the orthodontist’s treatment be carried out smoothly and achieve good results; otherwise, even if the orthodontist does a good job, good treatment results cannot be achieved. Third, choose the right braces. Orthodontic braces are devices used by doctors to straighten teeth, and there are several types used in clinics nowadays. There are domestic, imported, which according to its production materials, structure and certain performance and other aspects of the different kinds. Each has its own characteristics, of course, the price varies greatly. In fact, the aligner is only a tool, orthodontist use it to correct teeth, treatment results of good and bad aligner is not the key factor, but the orthodontist to apply its ability. As long as the orthodontist’s orthodontic technology is good, with general braces can still achieve good treatment results; if the orthodontist’s technology is not up to scratch, with even the best braces are not good. Of course, for the same orthodontist, the better the braces used, the smoother the operation will be, the smoother the correction process will be, the better the corrective effect may be. Patients can choose the appropriate braces according to their own conditions; those with poor economic conditions can choose domestic ones; those with good economic conditions can choose imported ones or those with better performance. In short, patients who straighten their teeth, as long as they choose a qualified orthodontist, use the appropriate braces, coupled with their own positive cooperation, they will be able to get a more satisfactory orthodontic results.
