Maybe many people don't know what Invisalign is. Simply put, Invisalign is an invisible dental appliance, which can not only meet the needs of orthodontics, but also avoid the shortcoming that traditional bracket orthodontics can see "Kouga", so it is very suitable for women who love beauty.
Q2: What's the difference between Invisalign and general orthodontics?
First of all, from the perspective of orthodontic speed, the two are almost the same. In terms of time, Invisalign wears braces for 22 hours a day, only two hours less than bracket braces, and the corrective force also plays a similar role. In terms of strength, the speed of tooth movement is limited, and the strength required to reach this speed can only be considered as moderate, and both kinds of appliances can achieve it. Therefore, the correction speed of the two braces is similar.
Q3: Advantages of Invisalign.
Except aesthetics, the principle of orthodontics and the biological basis of tooth movement are the same as those of traditional orthodontics. However, in orthodontics in Invisalign, every step of tooth movement can accurately locate which teeth are moving, and the tooth movement is precisely designed as a displacement of 0.25mm, which is softer than the steel wire used in traditional orthodontics and more conducive to the health of teeth. The corrected afterburner in Invisalign is safe, reliable, controllable and predictable.
Question 4: Invisalign's shortcomings.
1, I have to take off my braces at least three times a day. A few days before I put on my new braces, it was more painful to take them off. Taking off my braces feels like someone pulled out one of your teeth, and wearing braces feels like putting a pair of shackles on your teeth. For those who lack perseverance and self-discipline, Invisalign does not recommend it.
2. For people with severe malocclusion, Invisalign is not suitable, so it is suggested to choose traditional correction methods.
3. In terms of cost, Invisalign is much more expensive than ordinary correction, and you need to pay a corresponding price to become beautiful.
