1.The best age for orthodontic treatment? There is no strict age limit for orthodontic treatment. It is generally believed that it is better for children around 12 years old whose bodies are in the growth period to receive orthodontic treatment. At this time, permanent teeth have erupted, and the development of the jaw and face has reached 85%. However, the misalignment of the “circumference of the sky” and the “ugly face” should be interfered with the treatment as early as possible. Of course, if the child’s upper and lower jaws are normal, but only the teeth are not aligned, wait until high school or college to start orthodontic treatment can also achieve good results. In conclusion, different malocclusions have their different treatment timing and treatment plans. Parents are advised to bring their children to the hospital for regular checkups and listen to the doctor’s advice. 2.Does orthodontic treatment hurt? Orthodontic brackets are bonded to the teeth by adhesive, and archwires give the brackets force to move the teeth. In the first 1-2 weeks, the teeth feel sore due to the force. The mucous membranes of the mouth may also be bruised by the brackets and archwires, but these are tolerable. They usually go away on their own after a week and do not require medication. Patients may also feel tightness and pain in the teeth after each follow-up visit with additional force, but it is very mild and usually disappears automatically after 2-3 days as well. If severe pain occurs, it is abnormal and requires prompt medical attention. Wearing mechanical braces and functional braces need 2 weeks to adapt, at this time you can gradually increase the time of wearing the aligners, such as from the beginning of wearing 2 hours a day to wear. Subsequently 4 hours —–, the child will soon adapt. 3, orthodontic teeth will be loose? Teeth in the process of moving, periodontal membrane, alveolar bone and other supporting structures will undergo corresponding alterations. Some patients will experience mild loosening of the teeth, soreness and discomfort, chewing weakness and other phenomena, which is a normal reaction of the teeth. After the end of orthodontic treatment, these phenomena will disappear and the looseness and tightness of the teeth will return to normal. 4.How long does it take to straighten teeth? Orthodontic treatment takes about two years. Simple malocclusion without bone problems can be treated in 1.5 years. Severe malocclusion that requires Phase I functional treatment + Phase II fixed orthodontic treatment will take 3-4 years. Common fixed orthodontics is completed in three phases. The first phase is to align and level the teeth. Aligning the teeth usually takes about 4 months to complete; leveling the arch takes about 5 months. The second stage is to close the extraction gap and adjust the back teeth relationship. The extraction space is generally 7.6 mm, and is closed at a rate of 0.5 – 1 mm per month, taking about 6-10 months to complete. The third stage is the fine adjustment of the occlusal relationship, which takes about 5-9 months. Patient cooperation is very important. With good cooperation, it can usually be completed as planned. 5.Is there any fast track orthodontics? No, there is not. The reason is described above. Society often see advertisements: 7 days fast teeth correction. In fact, this is the concept of stealing: porcelain or all-porcelain teeth and other crowns to restore teeth as orthodontic treatment. Restorative dental treatment is mainly for the restoration of missing teeth, dental defects, root canal treatment of dead pulp teeth and enamel dysplasia of the teeth, its normal form of the teeth have a certain degree of destructive, and is irreversible. Orthodontic treatment slowly moves the teeth to their normal position through braces, which is not damaging to the teeth. Some “buck teeth” patients should think twice before choosing porcelain teeth: “Buck teeth” show that the teeth are basically aligned, and the main problem is the protrusion of the teeth and the bone in the dental bed. Porcelain teeth can not solve the problem of protrusion, and will also lead to inflammation and discoloration of the gums. 6, orthodontics need to do those checks? In addition to the routine examination of oral cavity, face and temporomandibular joints, the examination to be completed in the first visit are: 1,Preoperative memory model. To help clarify the diagnosis and develop a treatment plan, and as a comparison between before and after treatment. 2, Photographs. As a measurement and retention, comparison.3, X-ray. Surface tomography, lateral cephalometric films and TMJ films to clarify whether the teeth, maxilla, mandible and TMJ are normal. CBCT is now used as a routine examination program. 7.What are the characteristics of adult orthodontics? More and more adults are now requesting orthodontic treatment to enjoy the fun brought by modern technological advances! 1. Skeletal development of adults has been completed and the potential for jawbone development no longer exists, therefore, adult teeth move slower and both treatment and retention time are longer. 2. Adults often have other dental problems such as caries, periodontal disease, TMJ disease and missing teeth, all of which can make orthodontic treatment more difficult. 3. Adults are active in requesting orthodontic treatment, have clear orthodontic goals and aesthetic requirements (social needs), and have higher aesthetic requirements for aligners, such as choosing ceramic brackets, invisible bracketless orthodontic treatment or lingual braces. 8.After orthodontic treatment, do I need to wear the retainer for life? Retainers are usually worn for 2 years. In the first year, they are worn both during the day and at night (24H), and in the second year, they are worn at night (12H). For adults, it is better to wear the retainer for a longer period of time, and it is best if you can take it out and wear it every now and then. Of course, if you have the conditions to choose the lingual bonding type retainer is more comfortable, can be worn for a long time to maintain.
