The intense college entrance exams and midterm exams have once again come to an end, and students who are physically and mentally exhausted finally have a wonderful summer vacation. When parents and children are cheerfully planning various summer trips, or extracurricular studies, I wonder if you and your children have considered orthodontics into the plan? ”Orthodontics”, or “orthodontic” is professionally known as orthodontics, refers to the process of using orthodontic techniques or surgical means to correct various malocclusions using orthodontic appliances. So what is malocclusion, or what are the malocclusions? The most common ones are misalignment, crowded misaligned teeth, or tilted, twisted, or protruding outside the dental arch, “tiger teeth” is one of the typical manifestations; anterior malocclusion, commonly known as “envelope” or “lower pocket teeth The lower front teeth are wrapped around the upper front teeth and often have a special “crescent shape”; “deep overdentures,” often called “buck teeth,” in which the upper front teeth protrude so far forward that the lips cannot cover them In deep overbite, the upper and lower front teeth are so deep that the upper front teeth completely cover the lower front teeth and the lower front teeth are almost invisible when observed from the front; in open bite, the upper and lower front teeth do not bite together and are not in contact. In addition, like sparse teeth alignment, gaps; facial asymmetry, partial dentition, etc. are also common manifestations of malocclusion. There is an optimal age for orthodontics, usually around 13 or 4 years old, when your child is just starting his or her first year. At this time, the big teeth have basically been replaced, the arch is basically developed, the malocclusion is set, and all kinds of malocclusion can be actively orthodontic during this period. For some special types of malocclusion, such as anticlino and deep overbite, early orthodontic treatment is recommended to provide a favorable environment for the growth of the upper and lower jaws through simple early orthodontic treatment at the age of 4-5 years, to guide the jaws to grow in a normal direction and simplify the orthodontic process. At the age of 9-12 years for boys and 8-10 years for girls, i.e., the period of tooth replacement, it is appropriate to correct some functional malocclusions (caused by bad habits or occlusal interference), such as anticlusion, misalignment of the upper and lower dental arches, and severe misalignment of individual teeth. In order to utilize the growth potential of jaw bone, promote or resist the growth of jaw bone, and provide the possibility of coordinated development of upper and lower jaw bone. Although adolescents are the main population for orthodontics, the development of modern orthodontic technology has allowed orthodontics to break through the age limit. Adults, although past their growth spurt, can still be orthodontically treated for malocclusion to achieve the goals of improving appearance, restoring normal occlusion, and promoting oral health. Orthodontic treatment for patients with periodontal disease and orthodontic treatment to provide restorative space for veneers, implants, etc. have also become very common. However, early orthodontic treatment is still advocated for very serious malocclusion, such as anticuspid. The duration of orthodontic treatment is long, usually one and a half to two years, and monthly follow-ups are required. Summer is the peak time for orthodontic treatment because, on the one hand, both parents and children are able to take a break from their busy school schedule and have time to fully understand orthodontic knowledge and discuss orthodontic treatment plans with their orthodontist. On the other hand, it is also beneficial for the children to take advantage of the two-month period to get used to the orthodontic appliances. Students who have just entered middle school or high school choose to start orthodontic treatment at this time, the curriculum is relatively less stressful, the time is better arranged, and they are able to complete the orthodontic treatment and remove the aligners before their junior or senior year, without delaying their studies. Students who have just entered college, because the next 3 to 5 years will be fixed in one place to go to college, the curriculum is more flexible, orthodontic treatment at this time is also a better choice, time does not affect the job search, further education or study abroad. All in all, orthodontics has become a fashion increasingly concerned about people. Orthodontics is not only the pursuit of bite function improvement, but also the pursuit of aesthetic enhancement. Both students and adults who have malocclusion should seek orthodontic treatment to welcome a new life with a bright smile and a new posture.
