The goal of this clinical trial is to test the effectiveness of lingual aligners in adults.

The main question to answer is:

- Are lingual aligners effective in achieving desired and predicted tooth movements?

Also:

* Patient discomfort and pain

* Appliance defects

* Patient compliance

* Chair and treatment time

Key inclusion criteria:

* Adults older than 18 years old

* About to undergo orthodontic treatment

Key exclusion criteria:
