Tooth malocclusion is usually achieved by orthodontics to achieve the purpose of harmonious shape and proportion, but simple orthodontics only adjusts the front, back, left and right relationship of teeth, and has no effect on maxilla and mandible. After all, adults have been stereotyped and have not changed much, so cognition must be clear. If your purpose is to correct occlusion, it is recommended to do orthodontics; But if you add the improvement of appearance, there are usually three choices: beautiful teeth to create a shiny smile 1. Orthognathic surgery: that is, orthodontists design the way and distance of maxillary and mandibular bone movement according to the relative relationship of bones, which usually requires general anesthesia, and the recovery period is about three months or more, but the effect is the best. Orthognathic surgery will change the face shape to a considerable extent. 2. Rhinoplasty and chin surgery: This is a simplified treatment. In other words, if you belong to the teething crowd, because the mouth shape is sharp, it affects the development of the nose and chin, leading to the collapse of the nose and the retraction of the chin, which is very direct and bright. Only local anesthesia is needed, and the recovery period is about 7 days. The wound is hidden in the nostril and lower lip gum, and visual balance can be achieved without special suture removal and follow-up visit. 3. Lip shaping: Usually, the small hard structure protrudes forward, forcing the lip to thicken to cover the teeth, so the proportion of lip repair is greatly increased, that is, the lip is trimmed within a reasonable range. To sum up, whether the teeth bite correctly or not has a great influence on people's appearance. Therefore, it is very important for the normal development of human facial bones to develop correct living habits and correct malocclusion through orthodontics as soon as possible.
