It may make people hear that you don't know your specific situation, so it is difficult to give better advice. If your teeth are mild and you are an elderly patient who doesn't want to wear a fixed appliance, I suggest you choose an adult appliance. It was designed by Dr. Farrell, an Australian orthodontist, in the early 1990 s, using computers and combining a lot of orthodontic clinical work, and achieved good results through clinical application. This series of products have obtained international patents. It not only has the function of mechanical appliance, but also has the function of functional appliance. It is not only a muscle function trainer, but also a retainer, which integrates multiple functions. Advantages:

1, simple and practical, convenient and relaxed. Avoid the trouble and inconvenience of arch wire correction.

2. It is especially suitable for people who can't or can't accept archwire correction without damaging teeth and oral soft tissues.

3. The appliance is made of high-tech materials with strong memory function, high elasticity, no side effects, no peculiar smell and stable performance.

Disadvantages: the scope of application is relatively fixed, and the scope of correction is relatively narrow. It is strictly forbidden to use it for severely crowded patients. Therefore, when you buy again, you must provide multi-angle pictures such as the front and side of your teeth to judge whether this product is suitable for your situation. I bought it from Taobao at that time, and the effect was good. I suggest you consult. The first three digits of the seller's deduction number are 139, the middle three digits are 1 15 and the last three digits are 195. I have a look, and there are also 6- 12 children. The landlord had better consult this situation before making a decision.
