My sister wanted to have her teeth straightened last year. As an art student, she is worried that going back will affect her art test. She chose elegance and beauty, and her skills are quite good. What is useful is the advanced 3D simulation technology, which simulates the tooth movement process through 3D animation and intuitively foresees the related treatment process and results. Moreover, this kind of invisible braces is quite cost-effective, and the most important thing is the effect, especially when you are busy at work or nervous at study.
