The Science Behind Invisalign: How Does It Work?

Invisalign braces are a trendy solution today. They are clear, removable aligners to straighten teeth and correct various dental problems. Let's get to know the features and benefits of Invisalign better!

What Is Invisalign?

Invisalign is a teeth-straightening system that uses a series of clear plastic aligners custom-made to fit the teeth.

These aligners gradually move teeth into their planned positions, providing a discreet and more comfortable alternative to metal braces.

How Are Aligners Made and Used?

The Invisalign treatment process begins with a consultation with your orthodontist.

The main task of this visit is to create digital impressions of the teeth to obtain a 3D model of the mouth. Using innovative computer technology in orthodontics, the doctor develops an individual treatment plan, noting the exact movements of the teeth at each stage of the process.

Next, using specific 3D printing technology, a series of transparent plastic aligners are manufactured. The patient should wear each set for about 1–2 weeks and replace it with the next set in the series.

Typically, patients wear their aligners all day, removing them to eat, drink (except water), brush their teeth, and floss.

What Dental Problems Are Invisalign Prescribed For?

Invisalign is typically used to correct orthodontic problems such as:

  • Crooked or misaligned teeth
  • Overcrowding
  • Gaps between teeth
  • Overbite
  • Underbite
  • Crossbite

Please note: Only a qualified dentist can determine the appropriateness of using this system. The fact is that Invisalign may not be suitable for correcting cases that are too complex or severe. For some patients, the only way to restore their perfect smile is braces.

What's Better — Invisalign or Braces?

The choice between Invisalign and traditional braces depends on treatment goals, the orthodontist's recommendations, and the patient's individual preferences. Both options have their features.


Invisalign aligners are made of clear, safe plastic and are invisible. Of course, this makes them more attractive compared to noticeable metal braces.

Clear aligners are especially popular among children, teenagers, and adults who feel uncomfortable showing their dental problems to others.


Invisalign aligners are smooth and comfortable to wear every day for long periods. They do not have hard wires or brackets that can cause irritation or discomfort.

However, even such a system can cause slight discomfort. For example, some patients complain of short-term pressure when switching to a new set of aligners.

Removal Possibility

Invisalign are removable aligners. This feature greatly facilitates oral hygiene by brushing or flossing and also makes it possible to eat and drink almost without restrictions.

Unlike Invisalign, traditional braces are fixed structures. They require constant special care, dietary restrictions to prevent damage, and regular visits to the orthodontist for adjustments.


Both Invisalign and traditional braces are used to correct various orthodontic problems. The choice between these options depends on the individual patient's needs, lifestyle, and treatment preferences.

Thus, Invisalign is a universal orthodontic treatment option, the undeniable advantages of which are invisibility and comfort. However, its use and potential effectiveness should be discussed with an orthodontist, who will provide personalized recommendations based on individual dental needs and treatment goals.
