Introduction

Invisible orthodontics or Invisalign has become one of the most popular orthodontic treatment methods in recent years. This method is very suitable for those who want to straighten their teeth but don't want metal braces.

Section 1: What is Invisalign?

Invisalign is an orthodontic system that uses clear, removable aligners. These aligners are custom-made for each patient and gradually guide teeth to the desired position.

How Does It Work?

  1. First, a digital scan or impression is taken of your mouth
  2. Using advanced software, your treatment plan is designed
  3. A series of clear aligners are made for you (usually 20-40 pieces)
  4. Each aligner should be worn for 2-3 weeks, then move to the next
  5. Every 6-8 weeks you should visit the clinic to check your progress
