Invisalign

Invisalign is a method of straightening teeth using clear, removable plastic trays (called aligners) instead of fixed metal braces. The trays gradually move misaligned teeth into position and are almost invisible in everyday life.

Invisalign is a brand name for a type of "invisible" teeth straightening using transparent aligners. These custom-made trays fit like a thin shell over the teeth and apply targeted pressure to move them into the desired position over weeks and months. Unlike classic fixed braces, they can be removed for eating and brushing.

The process starts with an examination and a digital 3D scan of the teeth at the dentist or orthodontist. From this, an individual treatment plan is created and a series of aligners is manufactured. Each aligner is usually worn for around two weeks before moving on to the next. A high daily wear time (often about 22 hours) is essential, otherwise the result is delayed. Check-up appointments accompany the process.

The method makes sense for mild to moderate misalignments such as crowding, gaps or a slight overbite. For complex jaw or bite problems, fixed braces may be the better choice.

Pay attention to professional advice: not every case is suitable, and treatment belongs in experienced hands. Costs depend heavily on complexity, treatment duration and the practice, and are usually not covered by basic insurance. Ask for a transparent cost estimate in advance. A typical mistake is wearing the aligners too infrequently.

Example

A 29-year-old professional from Zurich is bothered by slightly crooked front teeth but does not want to wear a visible metal brace when dealing with clients. After a 3D scan at an orthodontic practice, she receives a series of transparent aligners and changes them herself at home every two weeks. Because she consistently wears the aligners for around 22 hours a day and only removes them for eating, the progress is clearly visible at her check-up appointments.

Frequently asked

How long does an Invisalign treatment take?

This depends heavily on the starting situation. Minor corrections can be completed in a few months, while more extensive misalignments take considerably longer. It also matters whether the aligners are worn consistently – too little wear time extends the treatment. A reliable estimate is provided by the specialist after the 3D scan.

Does health insurance cover the costs?

For adults, such teeth corrections done for aesthetic reasons are generally not covered by mandatory basic insurance. In certain medically justified cases or through private supplementary dental insurance, a contribution may be possible. Clarify this with your insurer before starting treatment and ask for a cost estimate.

Is Invisalign suitable for every misalignment?

No. Transparent aligners are mainly suitable for mild to moderate misalignments such as crowding, gaps or a slight overbite. For complex jaw or bite problems, fixed braces can be more effective. A professional examination will determine whether the method fits your case.
