What are invisible aligners?

Invisible aligners are a system of removable, transparent aligners that correct teeth positioning discreetly and comfortably, without the need for metal brackets or wires.

How long does invisible aligner treatment take?

Treatment duration varies between 6 to 18 months, depending on case complexity. Simpler cases can be resolved in a few months, while more complex cases may take longer.

Can I remove the aligners to eat?

Yes, one of the great advantages of invisible aligners is that they can be removed for eating and drinking. It is recommended to wear the aligners for at least 22 hours a day for best results.

Do invisible aligners cause pain?

You may feel some discomfort in the first few days of each new aligner, but it is generally much more comfortable than traditional braces. The initial pressure is a sign that the treatment is working.

What is the price of invisible aligners?

The price varies according to case complexity and the number of aligners needed. We offer an initial consultation where we evaluate your case and present a personalized quote with payment options.

Do invisible aligners work for all cases?

Invisible aligners are effective for most dental misalignment cases, including crowded teeth, spacing issues, or irregular bites. Very complex cases may require complementary treatments.

How often should I visit the clinic during treatment?

Generally, follow-up appointments are scheduled every 6 to 8 weeks to monitor progress and deliver new aligners. The frequency may vary depending on the case.

Can I play sports with invisible aligners?

Yes, you can practice sports with the aligners. For contact sports, we recommend removing the aligners and using an appropriate mouthguard for better protection.

Are invisible aligner results permanent?

Results can be long-lasting if you use retainers as recommended. After treatment, it is essential to wear a retainer to keep teeth in the correct position.

From what age can you use invisible aligners?

Invisible aligners can be used by teenagers from age 12-14, when most permanent teeth have erupted. They are also very popular among adults of all ages.

What is the difference between Invisalign and Spark?

Both are premium aligner systems. Invisalign uses SmartTrack® material with decades of clinical experience. Spark uses TruGEN™ material, which offers greater clarity and stain resistance. Both provide excellent results - the choice depends on specific case needs.

What is the TruGEN™ material used in Spark aligners?

TruGEN™ is a state-of-the-art material developed specifically for dental aligners. It is more transparent than conventional materials, more resistant to stains from coffee, wine and other foods, and maintains consistent force throughout the wear period, providing more predictable tooth movements.

How does digital technology improve aligner treatment?

We use 3D intraoral scanners to create precise digital impressions, eliminating traditional molds. Advanced software with artificial intelligence plans each treatment stage, allowing you to visualize the final result before starting. 3D printing ensures aligners perfectly fitted to your needs.

Are invisible aligners better than traditional braces?

Each system has its advantages. Aligners are more aesthetic, comfortable and allow better oral hygiene. Traditional braces may be more effective in very complex cases. During consultation, we evaluate the best option for your specific case, potentially combining both techniques.

What types of dental problems can be treated with invisible aligners?

Aligners effectively treat: crowding, spacing between teeth, crossbite, overbite, open bite and general misalignments. Mild to moderate cases have excellent results. More complex cases may require attachments (small bumps on teeth) or combined treatment.

How can I see the final result of my treatment before starting?

At the initial consultation, we perform a 3D scan of your mouth and use simulation software to show how your teeth will look after treatment. This digital simulation allows you to visualize the final smile and make adjustments to the plan before starting, ensuring you are satisfied with the expected result.

Do aligners affect speech?

There may be a slight adjustment period of 1-2 days when placing the first aligners, during which you may notice a minor speech change. Most patients adapt quickly and speak normally. Modern aligners are very thin and well-fitted, minimizing any impact.

Orthodontic Conditions

Conditions We Treat with Clear Aligners

Clear aligners effectively correct a wide range of orthodontic issues, from mild to moderate complexity. Here are the conditions we commonly treat:

Crowding
When teeth overlap due to insufficient space in the jaw, making cleaning difficult and increasing cavity risk.
Mild to Moderate
Spacing (Diastema)
Gaps between teeth that can trap food, affect speech, and impact smile aesthetics.
Mild to Severe
Overbite (Deep Bite)
Upper front teeth excessively overlap lower teeth, potentially causing wear and gum irritation.
Mild to Moderate
Underbite
Lower teeth protrude past upper teeth, affecting chewing function and facial profile.
Mild to Moderate
Crossbite
Some upper teeth sit inside lower teeth when biting, causing uneven wear and jaw strain.
Mild to Moderate
Open Bite
Front teeth don't touch when back teeth are closed, affecting biting and speech clarity.
Mild to Moderate
Midline Shift
Center line of upper and lower teeth doesn't align, affecting facial symmetry and bite.
Mild to Moderate
Tooth Rotations
Individual teeth twisted out of proper alignment, creating cleaning challenges and aesthetic concerns.
