What is the difference between Invisalign and traditional fixed correction?

Traditional fixed orthodontics: As the name implies, fixed appliance is an appliance that patients can't remove by themselves. Generally, it consists of three parts: band, bracket and arch wire.

Invisalign: Invisalign is an invisible dental instrument designed and manufactured by Align Technology Company in North America. It can not only meet the needs of orthodontics, but also avoid the shortcoming of "Kouga" in traditional bracket orthodontics. It is the most advanced orthodontic method in the market.
