Invisalign - the invisible braces

Invisalign is a modern, virtually invisible method for correcting misaligned teeth using clear plastic aligners. The treatment allows for gentle and comfortable tooth movement without wires, brackets, or restrictions on daily activities. It is ideal for adults and teenagers who value aesthetics, flexibility, and comfort.

What is Invisalign?

Invisalign is an orthodontic treatment system that uses custom-made, clear aligners. These removable plastic aligners are replaced every 1–2 weeks to gradually move the teeth into their ideal position. The treatment is suitable for correcting:

Crowded teeth
Gaps (diastema)
Rotational and tilting malocclusions
Mild to moderate complex malocclusions (depending on the diagnosis)

For discreet tooth correction

Invisalign is virtually invisible, comfortable to wear, and particularly well-suited for everyday use—ideal for patients who want discreet teeth straightening.

Many adults want straight teeth but do not want to wear noticeable braces. Invisalign offers the ideal solution here. The clear aligners are barely visible in everyday life and do not interfere with speaking or smiling. Even complex orthodontic treatments can be carried out precisely with modern Invisalign systems—gently, predictably, and aesthetically.

The Invisalign treatment procedure

Invisalign treatment begins with a detailed consultation and a digital analysis of your teeth. Using a 3D scan, we create an accurate model of your teeth. This allows us to simulate how your teeth will change over the course of treatment—and what your smile will look like afterward. These are the steps of the treatment:

Examination & Consultation

Assessment of tooth alignment, photos, X-ray diagnostics
Clarification of treatment goals and expectations

Digital 3D scan (no impressions)

Creation of a precise treatment plan
Simulation of the expected final result

Manufacturing of the aligners

Custom fabrication in the lab
Start of treatment
Aligners are worn 20–22 hours a day
Switch to the next set every 1–2 weeks

Follow-up appointments

Every 6–8 weeks for review and fine-tuning

Retention phase

After completion, a retainer (wire or retainer tray) is inserted to stabilize the result

Important notes

The aligners should be worn for at least 20–22 hours a day.
Drink only water while wearing aligners (no tea, coffee, or soft drinks)
Regular oral hygiene and professional teeth cleaning are recommended.
The result depends heavily on how consistently you wear them.
In more complex cases, a combination with attachments (small tooth-colored dots) may be necessary.
Long-term stabilization (wire retainer) is crucial after each treatment.

FAQ about Invisalign

Invisalign treatment involves wearing custom-made aligners that gently move the teeth into the desired position. Each Invisalign aligner is worn for about two weeks before being replaced by the next one. This allows for step-by-step correction—pain-free, metal-free, but with visible progress.

The duration of treatment depends on the individual initial findings. Minor corrections can be completed in as little as four to six months, while more complex cases usually take between twelve and eighteen months. Thanks to digital planning, you will receive a precise estimate of the treatment duration right from the start.

The cost of Invisalign varies depending on the complexity of the treatment and the number of aligners required. At Zahnkronenhalle Zurich, we provide you with a transparent cost breakdown during your initial consultation. Since this is a long-term investment in your dental health and aesthetics, we offer flexible payment options.

For best results, aligners should be worn for about 20 to 22 hours a day—including at night. They should only be removed when eating, drinking, or brushing your teeth. This ensures that your teeth continue to move steadily, reliably achieving the desired result.

Yes, Invisalign is particularly popular among adults who prefer invisible braces. It allows for aesthetic teeth straightening in both professional and personal settings without others noticing. Thanks to precise digital planning and modern materials, the results are just as effective as those achieved with traditional braces—only much more comfortable.

Once treatment is complete, an Invisalign retainer helps stabilize the results. During the first few months, it is usually worn every day; later on, only at night. Alternatively, a fixed wire retainer can be used, which is discreetly attached to the inside of the teeth. This aftercare is essential to ensure that your new smile lasts a lifetime.
