Due to the patient’s limited knowledge of orthodontics and unclear about the entire situation of malocclusion, aligning the front teeth as part of the goal of orthodontic treatment is understandable, aligning the front teeth is also relatively easy to treat, but some orthodontists so-called orthodontic treatment only align the front teeth as the only goal, as long as the front teeth This is not professional enough, and is also extremely irresponsible attitude, except for a small number of light degree of malocclusion, simple local teeth alignment often does not effectively change the face and bite relationship, so as a professional orthodontic treatment doctor in meeting the simple “alignment” at the same time should pay more attention to Therefore, as a professional orthodontist, while satisfying the simple “alignment”, he should pay more attention to other malocclusions in the mouth, correct the relationship between the upper and lower jaw arches according to the patient’s own conditions, seek the coordination of the arch length, width and height in three dimensions as much as possible, establish good posterior teeth relationship, improve the relationship between the upper and lower jaws, and achieve the overall coordination of lip shape and facial protrusion height, which are more difficult and require more time. If further consideration is given to the mandibular function and TMJ, the results are more desirable and less easy to achieve. Therefore, the overall goal of the ideal orthodontic treatment should be the coordination, beauty, health and stability of the teeth and jaws. Orthodontic treatment is a very specialized and delicate treatment technique, which usually takes about 2 years to complete, and the initial measurement and design work determines the effect of orthodontic treatment. A properly trained orthodontist who is conscientious and responsible in orthodontic treatment will generally not cause complications to the patient. However, if the doctor makes a mistake in the diagnosis of misalignment, orthodontic design, or improperly operates during treatment, it can sometimes cause some problems. For example: causing new misalignment; aggravating the existing TMJ dysfunction; excessive loosening or even loss of teeth; causing caries or periodontal disease. So when you decide to straighten your teeth you should have a full communication with your doctor, consciously learn more about general knowledge of orthodontics and choose a professional orthodontist.
