Modern people are becoming more and more demanding in terms of aesthetic appearance. Poorly aligned teeth and abnormal facial shape can greatly reduce facial value, and everyone wants to have beautiful teeth and a bright appearance. Orthodontic treatment (i.e., orthodontic treatment) is the current treatment for crowded misaligned teeth, lower pocket teeth, buck teeth, bimaxillary protrusion, overbite and open? The main method of treatment is orthodontic treatment. The orthodontist makes a customized orthodontic plan according to the patient’s specific situation and changes the alignment of the teeth by wearing various aligners to make the teeth straighter. Aligning teeth brings beauty and makes cleaning easier, thus greatly reducing the risk of dental caries and periodontal disease and helping to maintain our oral health. Orthodontics is not just about aligning teeth, it can even improve the shape of the face and solve functional problems caused by misaligned teeth and poor bite. Inability to bite properly can affect chewing, swallowing, and cause functional oral problems such as slurred speech and pronunciation. In addition, severe malocclusions, such as the common diastema, have a curved moon face shape when viewed from the side. Buck teeth formed by protruding teeth and crooked face caused by misalignment of bite can seriously affect the facial value and may cause patients to have low self-esteem. Through orthodontics, we can obtain a good bite, a coordinated and beautiful face, improve chewing efficiency, swallowing, breathing and pronunciation functions, and promote the functional movement of the temporomandibular joint and jaw, etc. These are not only beneficial to the function and beauty of the mouth and face, but also beneficial to the health of the whole body, enhance the patient’s self-confidence and gain mental pleasure. Orthodontics is a science, the orthodontic program development process requires analysis of very complex factors, the orthodontic process can not be “automatic”, you need to find a professional orthodontist, regular follow-up, orthodontists need to undergo formal training to carry out orthodontic treatment. Therefore, the majority of patients should choose a regular medical institution for treatment in order to obtain beautiful and healthy teeth.
