About This Treatment
You've heard of Invisalign — it's the most recognized name in clear aligners. But did you know that newer systems like Angel Aligner now offer comparable or superior technology? At our clinic, we evaluate your case individually and recommend the system that delivers the best results for your specific needs — not just the most famous brand.
We Understand Your Situation
Misaligned or crowded teeth can affect much more than the appearance of your smile. Many people feel self-conscious when smiling in photos, avoid certain social or professional situations, and may even experience difficulties with chewing or oral hygiene. If you have considered correcting your smile but hesitated due to the appearance of traditional braces, invisible aligners may be the ideal solution for you.

All premium aligner systems — including Angel Aligner, Invisalign, and Spark — effectively correct these orthodontic issues:

Upper front teeth excessively overlap lower teeth, potentially causing wear and gum irritation.

Lower teeth protrude past upper teeth, affecting chewing function and facial profile.
Mild to Moderate

Some upper teeth sit inside lower teeth when biting, causing uneven wear and jaw strain.
Mild to Moderate

Frequently Asked Questions
Find answers to the most common questions about this treatment.
Is Invisalign really better than other aligner brands?
Invisalign was the pioneer in clear aligners and has excellent brand recognition. However, newer systems like Angel Aligner have matched or exceeded Invisalign's clinical results. Angel Aligner uses AI-powered planning technology and has treated over 1.5 million cases worldwide. We recommend the best system for your specific case — not the most famous brand.
What is Invisalign?
Invisalign is a clear aligner brand that pioneered transparent orthodontic treatment. It uses removable aligners made from SmartTrack material. While Invisalign remains a good option, other premium systems now offer comparable technology and results.
How long does clear aligner treatment take?
Treatment duration varies between 6 to 18 months, depending on case complexity. Simpler cases can be resolved in a few months. All premium aligner systems work faster than traditional braces for most movements.
Can I remove the aligners to eat?
Yes, all clear aligners are removable. You can take them out to eat, drink, brush, and floss. It is recommended to wear them for 20-22 hours a day.
Do clear aligners cause pain?
You may feel some pressure for a day or two after switching to a new set of aligners. This is normal and a sign the teeth are moving. It is generally much more comfortable than traditional braces.
What is the price of Invisalign vs other aligners?
The price depends on case complexity. During your consultation, we'll present all options and their costs. Many patients are surprised to learn that Angel Aligner delivers equivalent results while often representing better value. We'll give you an honest comparison so you can make an informed decision.
Do clear aligners work for all cases?
Premium aligner systems can treat a wide range of cases, from mild to complex, including open bites, deep bites, and crossbites. Our doctors will evaluate which system is the right choice for you.
How often should I visit the clinic during treatment?
With clear aligners, clinic visits are typically every 6 to 8 weeks to check progress and pick up your next sets of aligners.
Can I play sports with clear aligners?
Yes, clear aligners are great for active lifestyles. For contact sports, you can remove them and wear a mouthguard if needed.
Are clear aligner results permanent?
Results can be permanent if you wear retainers as prescribed after treatment. All aligner brands offer compatible retainer options.
Are clear aligners suitable for teenagers?
Yes, all premium aligner systems offer teen-specific options with compliance indicators to track wear time. We'll recommend the best system for your teenager's needs.
Why do some dentists only offer Invisalign?
Some clinics have exclusive agreements with Invisalign or simply haven't adopted newer systems. We believe in offering multiple premium options so we can recommend the best system for each patient — not the one that benefits our business partnerships.
What makes Angel Aligner different from Invisalign?
Angel Aligner uses iOrtho AI-powered planning software and advanced masterForce technology. It's the world's second-largest aligner manufacturer with over 1.5 million cases. Many orthodontists consider it equally effective to Invisalign, with some advantages in digital planning precision.
Are the results the same with different aligner brands?
For most cases, yes. Premium aligner systems like Angel Aligner, Invisalign, and Spark all achieve excellent results when used by experienced doctors. The brand matters less than the expertise of your treatment provider. We'll recommend whichever system is clinically best for your case.
How does digital technology improve clear aligner treatment?
We use 3D scanners for digital impressions and advanced software to plan your treatment. Angel Aligner's iOrtho system uses AI for treatment planning, while Invisalign uses ClinCheck. Both allow you to see your predicted results before starting.
Are clear aligners better than metal braces?
Clear aligners (whether Angel Aligner, Invisalign, or Spark) are more aesthetic, comfortable, and allow better hygiene. Braces may still be needed for certain complex cases, but modern aligners can handle most orthodontic issues today.
What types of problems can clear aligners treat?
Clear aligners treat crowding, spacing, crossbite, overbite, underbite, and open bite. All premium systems are effective for most orthodontic problems.
How can I see the final result before starting?
Using 3D scanning and advanced treatment planning software, we can show you a simulation of your new smile during your consultation — regardless of which aligner system you choose.
Do aligners affect speech?
There may be a slight lisp for a day or two as you adjust, but most people adapt very quickly and speak normally.
How do I clean my aligners?
Clean them with a soft brush and lukewarm water. Some brands offer cleaning crystals. Avoid hot water to prevent warping.
Can I drink coffee or smoke with aligners?
Remove aligners for anything other than water to prevent staining and warping. Smoking can stain the aligners and affect oral health.
What happens if I lose an aligner?
Contact us immediately. We may advise you to wear the previous set or move to the next one while we order a replacement.
