Due to evolution, heredity, congenital influence or developmental abnormalities, human teeth are becoming more and more misshapen and misaligned. Since this part of the five senses is abnormal, the need for “orthodontic treatment” will arise. Most of the patients who come into the orthodontic department for consultation are still thinking about “orthodontics”, but, specifically for each patient, the severity of the deformity, the health risks or the need for orthodontic treatment, etc., will have to be determined by the professional doctor after detailed examination and confirmation. Some obvious bony deformities that have a serious impact on facial beauty or health should be treated without question. The specific implementation plan is based on the patient’s requirements and the affordability of the treatment to consider, most patients will not risk to “take a knife” to hurt the bones, so they mostly choose the treatment of malocclusion adjustment or cover up the bony problems, which is commonly known as “braces “With the joint efforts of doctors and patients, the main problems in malocclusion can generally be solved effectively. However, in the case of patients with “individual normal dentition”, where the oral and jaw systems are healthy, and there is only mild crowding or misalignment of individual or few teeth, the doctors should be more cautious, because in the middle of this, the pros and cons of “orthodontic or non-orthodontic” need to be considered. The advantages and disadvantages of “orthodontic or non-orthodontic” need to be considered. I found in long-term clinical work, adolescent patients who can take the initiative to accept orthodontic treatment, with good cooperation, everything is smooth; if parents are forced to orthodontic because of “aesthetic problems or fashion”, the degree of cooperation is often poor, the treatment effect will also be discounted, especially the degree of deformity itself is light, may be treated for six months The treatment effect will also be reduced, especially for those with a mild degree of malformation, which may have been treated for half a year and still have little change, but due to poor oral hygiene measures and tooth decay or gum redness and other complications, which is not worth the loss. For such patients, orthodontists need to communicate patiently and sign a treatment agreement before treatment, and parents should also consider before making a decision, rather than just following the trend. For adult orthodontic patients with mild malocclusion, the orthodontist can start treatment only after detailed communication before treatment so that they are fully aware of the efficacy and prognosis (stability) and can commit to wearing a long-term maintenance device; and for individual patients with particularly high expectations or excessive requirements, the orthodontist The orthodontist is best to back off. In the clinic, if the doctor ignores the latter two types of situations, inadvertently medical disputes arise, often resulting in damage to both doctors and patients. In conclusion, orthodontic treatment or not depends on the correct needs and mindset of patients and parents, and is also closely related to the professional ethics of the doctors, wishing all patients in need of orthodontic treatment the right assessment and appropriate treatment.
