Malocclusion refers to the disharmony between teeth and jaw, upper and lower dental arches, upper and lower jaw, jaw and craniofacial, which affects facial beauty and oral function. Severe malocclusion will also cause psychological and mental disorders in some patients, which will have a negative impact on further studies, job hunting and mate selection. Therefore, it is necessary to correct teeth, improve appearance and restore normal function.
Orthodontics is a long-term systematic project. Attention should be paid to children's dental health and development from the deciduous period. Some serious deformities, such as malocclusion, should be treated at the early stage of deciduous teeth. When children begin to change their teeth, they should establish contact with orthodontists, check regularly, observe the situation of tooth change, and intervene in some bad habits and tooth change obstacles that may cause malocclusion. Some serious skeletal deformities, such as maxillary protrusion, mandibular protrusion and jaw opening, need to be corrected early before puberty to block the development of malocclusion and guide the normal growth of teeth and jaws.
In the rapid growth and development stage of youth (generally, girls are113 years old, boys are 12- 14 years old), when teeth are replaced, jaws still have development potential. This is the best time for fixed correction, and most malocclusions can be solved at this time. Before correction, the doctor will do a detailed oral examination, take X-rays, take an analysis model and make a comprehensive analysis, so as to get the correct diagnosis and treatment plan. General malocclusion needs treatment for one to two years, and then it will turn into maintenance period. Some serious skeletal malocclusion may not achieve the ideal effect after correction due to abnormal growth, or relapse, and orthognathic surgery is needed for correction in adulthood.
Some adults have missed the best treatment opportunity for teenagers' rapid growth and development, but they still have a strong desire to correct their teeth. As long as the body is healthy and there are no systemic diseases, dental caries, periodontal diseases and temporomandibular joint diseases, orthodontic treatment can be carried out. If you suffer from the above diseases, you can still undergo orthodontic treatment after specialist treatment during the stable period of symptom elimination. However, there is a difference between adult orthodontics and children orthodontics. Adults have no potential for growth and development, and severe skeletal deformities can only be achieved through orthognathic surgery combined with orthodontic comprehensive treatment. Mild and moderate skeletal deformities can be concealed by compensatory tooth movement. Some patients can't achieve the ideal correction goal due to their own factors and diseases, so they can only carry out special treatment according to the actual situation in order to improve their appearance to the maximum extent and achieve functional occlusion. In addition, the metabolism of adults is slow, and the speed of tooth movement is slower than that of teenagers, so the treatment time should be prolonged accordingly. Adults have more social activities and have higher aesthetic requirements for electrical appliances. At present, there are ceramic brackets, lingual orthodontic techniques and bracket-free orthodontic systems to meet the aesthetic needs of adults.
