1.What kind of teeth need orthodontics? Orthodontic treatment is available for both children and adults. If a person’s teeth are uneven, bulbous, orthodontic, it will not only affect the beauty, but also affect the pronunciation and chewing function, at the same time, the disorder of tooth arrangement can also cause chewing pain, temporomandibular joint pain and other symptoms, which also has a certain negative impact on the psychology. Through orthodontic treatment, you can not only have a charming smile, but also prevent gum recession, bleeding, tooth loosening, early loss and other diseases. 2.Does orthodontic teeth hurt? Orthodontics is to align the teeth through external force, there will be some discomfort when you first wear it, generally after each visit to the doctor, that is, after the doctor to your aligner force, about 2-3 days of soreness, generally tolerable, a very small number of patients who are particularly sensitive to pain, you can eat a day or two of painkillers. Modern orthodontic treatment has taken many methods to make orthodontic patients feel more comfortable, these methods include: making the locking slot smaller and smoother, and improving the orthodontic treatment arch wire so that it can produce a continuous, gentle orthodontic force. 3.Will orthodontic treatment lead to loose teeth and loss of teeth? Some people think that orthodontic treatment will cause loose teeth in the future, or even early loss of teeth, orthodontic patients will damage the nerves due to tooth extraction, and even affect the patient’s intelligence. These are all unscientific. Modern orthodontic research reveals that the movement of the teeth produced by the force applied to the teeth by the aligner is not a simple mechanical movement, but a complex biomechanical movement. When the teeth are moved forward by suitable biological forces (controlled by high-precision aligners), the alveolar bone in front of the roots of the teeth is resorbed, enabling the teeth to move forward, but at the same time new normal alveolar bone is formed behind the roots of the teeth, thus enabling the teeth to grow firmly in their new positions, and eventually the orthodontic teeth are repositioned and the roots of the teeth are stable, without pathological changes caused by the movement of the teeth. Therefore, receiving regular orthodontic treatment will never produce trauma to teeth and periodontal tissues. 4.Does orthodontics require tooth extraction? The purpose of orthodontic tooth extraction is to relieve the crowded anterior protrusion and provide enough space for the teeth. Crowding is the most conscious symptom of malocclusion, accounting for about 70% of malocclusion. Generally speaking, mild crowding does not require extraction, while most cases of moderate crowding or more use extraction methods. An orthodontist with extensive clinical experience will design a comprehensive treatment plan from a dynamic developmental point of view, taking into account a variety of factors such as chewing and appearance, and after repeated discussions. The purpose of orthodontic tooth extraction is to establish a good bite relationship, improve chewing efficiency, and also improve the patient’s lateral form and facial shape, so that you have a more perfect appearance. 5.What is the best age for orthodontic treatment? Orthodontics is a long-term systemic project, and we should start to pay attention to the child’s dental health and development from the teething stage. Some serious malocclusions, such as retrognathism, should be treated early in the teething stage (3-6 years old). You should establish contact with your orthodontist when your child starts to replace teeth, have regular checkups, observe tooth replacement, and intervene in some bad habits and tooth replacement disorders that may cause malocclusion. Some serious skeletal deformities such as maxillary protrusion, mandibular protrusion, and open jaw require early orthodontic treatment before the onset of puberty (before age 12) to interrupt the development of malocclusion. By the time the rapid growth period of adolescence (generally 11-13 years old for girls and 12-14 years old for boys), tooth replacement is complete and the jaws still have developmental potential, which is the best time for fixed orthodontic treatment, most malocclusions can be resolved at this time. Although adult patients have missed the best time for treatment during the rapid growth and development of youth, but still can be orthodontic treatment, as long as the body is healthy, no systemic diseases, no dental caries, periodontal disease, temporomandibular joint disease, etc., can be orthodontic treatment. If you have the above-mentioned diseases, orthodontic treatment is still possible after specialist treatment and elimination of symptoms in the stable period. 6.Characteristics of adult orthodontics Adult orthodontics is the current popular trend, adults have higher requirements for beauty than children, many adult patients miss the opportunity of early orthodontic treatment due to various reasons, and urgently need to make up for this deficiency. Adults do not have the potential for growth and development, so it is best to use a combination of orthodontics and orthognathic surgery for some serious skeletal deformities to achieve the best results. For mild and moderate bony deformities, compensatory tooth movement can be used to disguise the skeletal defects. Some patients have difficulty in achieving the ideal goal of orthodontics due to their own limitations and the presence of diseases, and can only be treated specially according to the actual situation to maximize the improvement of the shape and achieve a functional bite. In addition, adults have a slow metabolism, the teeth move more slowly than adolescents, the treatment time should be extended accordingly. 7.Can patients with periodontal disease get orthodontic treatment? Periodontitis is a chronic inflammatory disease that invades the gums and periodontal tissues and is a destructive disease. Its main features are the formation of periodontal pockets and inflammation of the pockets wall, alveolar bone resorption and gradual loosening of teeth, it is the main cause of tooth loss, some adults due to crowded teeth, disorderly alignment, conventional oral hygiene care is difficult to achieve results, resulting in tartar accumulation, gum inflammation and congestion, hyperplasia, serious can form periodontal pockets, alveolar bone resorption. Through orthodontic treatment, the cause can be quickly removed, on the one hand, correct the abnormal adjacent teeth and the upper and lower joint relationship, eliminate the joint trauma, and at the same time, it can also align the teeth misalignment caused by periodontitis and close the gap; on the other hand, after the crowded teeth are treated by orthodontic treatment, the normal physiological structure is established, and the patient’s daily oral care such as brushing is effective, and the self-cleaning effect of teeth can be played, which can Prevent premature tooth loss in the elderly. When periodontitis involves teeth treated with orthodontics, its movement characteristics are different from the movement of conventional orthodontic teeth, and the treatment plan for such patients must be selected from professional hospitals, with the joint participation of periodontists, orthodontists and prosthodontists.
