Clear Aligners
Clear Aligners in Basel
In brief: Clear Aligners
Clear aligners are removable transparent trays used to move teeth gradually and discreetly. In Basel, we assess the indication, bite, periodontal health and treatment goals, including aesthetics, function and stability. Tooth movement is then planned digitally, with the expected duration, limitations and retention discussed in advance. This creates a structured treatment pathway with regular progress checks and realistic expectations.
Potential Benefits and Treatment Goals
Discreet: transparent aligners are generally much less noticeable than conventional fixed appliances.
Removable: they can be taken out for eating and oral hygiene, provided the prescribed wear time is maintained.
Digitally planned: a virtual treatment setup can illustrate the intended sequence of tooth movements before treatment begins.
No metal brackets: the trays are made from dental polymers; individual material sensitivities should still be considered.
Controlled treatment: planned tooth movements are reviewed clinically and adjusted if teeth do not track as expected.
Suitable for many adolescents and adults: including selected relapse or refinement cases after previous orthodontic treatment.
Who may be suitable for clear aligners?
Mild to moderate malalignment: crowding, spaces, rotations or tipping of teeth.
Selected bite corrections: for example certain crossbites, deep bites or increased overjet, depending on severity and skeletal relationships.
Refinement treatment: for tooth movement after previous orthodontic therapy.
Aesthetic alignment: to improve symmetry and tooth position within the dental arch.
Less suitable: severe skeletal discrepancies or complex movements that may require comprehensive orthodontic treatment, fixed appliances or interdisciplinary care.
Treatment Process
Digital planning
Assessment typically includes photographs and a 3D scan, with radiographs only when clinically indicated. A digital treatment setup is then created to plan the sequence of tooth movements.
Fabrication of the aligner series
Based on the treatment plan, a series of custom trays is produced. Each aligner is designed to move selected teeth incrementally.
Wearing and changing the aligners
Aligners commonly need to be worn around 20–22 hours per day and are changed according to the prescribed schedule, often every 7–14 days. Review intervals vary by case and system.
Stabilisation (retention)
After active tooth movement, retainers such as removable trays or bonded wires are usually required to reduce the risk of relapse.
Scientific Context
Effectiveness: clear aligners can achieve many mild to moderate orthodontic movements, but predictability varies by movement type and case complexity; refinements may be required.
Comfort: many patients report less soft-tissue irritation than with fixed appliances, although pressure or tenderness is common after changing aligners.
Predictability: digital planning is valuable for visualising treatment, but actual tooth movement does not always match the virtual setup exactly and must be monitored clinically.
Long-term stability: retention is essential after orthodontic treatment because teeth can move again over time, regardless of the appliance used.
Costs and Individual Treatment Planning
Costs depend on complexity, treatment duration and the number of aligners required. An individual estimate is provided after assessment and digital planning.
Type of treatment | Typical range |
Small aesthetic correction (front teeth / limited aligner series) | CHF 2,500–4,000 |
Moderate malalignment (full dental arch) | CHF 4,500–6,500 |
More complex correction (extended movements / both jaws) | CHF 6,500–8,500 |
Retainers (removable or fixed) | CHF 300–600 |
Frequently asked questions
How long does the treatment take?
It depends on the starting situation and treatment goals. Many cases take roughly 6–18 months, while limited corrections may be shorter.
Does it hurt?
A new aligner often causes pressure or mild tenderness for the first day or two. Significant or persistent pain should be reviewed.
How often do I need to wear the aligners?
Usually around 20–22 hours per day, removing them mainly for eating, drinking anything other than water, and oral hygiene.
Will aligners affect my speech?
A slight temporary change in speech can occur, especially at the beginning, but most patients adapt quickly.
Will my teeth stay in position afterwards?
Retention reduces the risk of relapse but cannot eliminate it. Long-term retainer wear is generally recommended after orthodontic tooth movement.
Summary
Clear aligners can correct selected tooth-position problems with a removable appliance and digitally planned treatment sequence, while preserving access for normal oral hygiene.
If you would like to know whether clear aligners are suitable for your case, we can assess your bite, tooth position and periodontal health in Basel and explain the expected possibilities, limitations, duration and retention requirements.
Diagnostics and Planning
Before tooth alignment, the dental arches, bite, gums, bone conditions and treatment goals are assessed. Planning considers not only the visible tooth position but also function, biological limits and the retention required after active treatment.
Limitations, Risks and Alternatives
Tooth movement requires biological time and consistent cooperation. Pressure sensitivity, temporary irritation, root resorption or changes in the gums are possible side effects. Retention is essential after active treatment because teeth can move again.
Clear Aligners in Basel: experience and clinical perspective
In our Basel practice, tooth-alignment treatment is integrated into the overall functional and reconstructive plan. More complex orthodontic or skeletal questions are planned together with specialist orthodontists or maxillofacial surgeons.More about Dr Thomas Gasser’s training and qualifications.
