What Is Invisalign Treatment?
Invisalign is the world's leading clear aligner orthodontic system — a series of custom-fabricated, removable transparent plastic trays that gradually and precisely shift your teeth into perfect alignment. Unlike traditional metal braces with their brackets, wires, and associated dietary restrictions, Invisalign aligners are virtually invisible, fully removable, and exceptionally comfortable — making them the preferred orthodontic choice for adults and teenagers across Chennai seeking a discreet path to a straight smile.
At Sahana Dental Clinic, our certified Invisalign provider uses SmartTrack® material aligners — engineered for precise, predictable tooth movement — combined with ClinCheck® 3D treatment planning software that digitally maps your entire tooth movement journey from start to finish. You can view your expected final result even before you receive your first aligner set.
"ClinCheck® 3D technology means we can show you exactly how your teeth will move at every stage — and what your smile will look like at the end — before treatment even begins."
Is Invisalign Right for You?
Invisalign successfully treats a wide range of orthodontic conditions. Ideal candidates include patients with:
Crowded or overlapping teeth that are difficult to clean
Spacing or gaps between teeth affecting appearance
Overbite — upper teeth overlapping lower teeth excessively
Underbite — lower jaw protruding forward of upper jaw
Crossbite — teeth not meeting correctly side to side
Open bite — teeth not touching when mouth is closed
Adults or teens who want orthodontics without metal braces
Relapse cases where previously straight teeth have shifted

Frequently Asked Questions
Invisalign treats a wide range of alignment issues including crowding, spacing, overbite, underbite, crossbite, and open bite in both adults and teenagers. Very complex skeletal discrepancies may still require traditional appliances. A complimentary digital scan at Sahana Dental Clinic will confirm your suitability precisely within a single appointment.
Treatment duration ranges from as little as 6 months for minor corrections to 18 months for more complex cases. Most adult Invisalign patients at Sahana complete treatment in 12–14 months. Consistent compliance — wearing aligners for the recommended 20–22 hours daily — is the single most important factor in staying on track with your projected timeline.
Most patients experience mild pressure or slight discomfort for the first 1–3 days when switching to a new aligner set — this is expected and indicates your teeth are actively moving. There are no sharp metal edges, bracket emergencies, or poking wires. Most patients find Invisalign significantly more comfortable overall than traditional braces throughout treatment.
Invisalign treatment at Sahana is priced based on case complexity — Lite (minor corrections), Moderate, and Comprehensive tiers. We provide detailed, transparent quotations after your complimentary digital scan. Flexible 0% EMI payment plans are available across all treatment tiers, making Invisalign genuinely accessible for most budgets.
Yes, with ease. Unlike metal braces, Invisalign aligners can be removed during contact sports — simply replace with a mouthguard during play. Wind and brass instrument players can remove aligners during practice sessions, provided total daily wear of 20–22 hours is maintained. This flexibility is one of the major lifestyle advantages Invisalign offers over fixed appliances.
Absolutely. Invisalign Teen is specifically designed for younger patients whose teeth may still be erupting. It includes compliance indicators (small blue dots that fade with wear) to track daily usage, and replacement aligners for any that are lost or damaged — giving parents and young patients complete peace of mind throughout treatment.
Without retention, teeth naturally tend to drift back toward their original position over time — this is true for any orthodontic treatment. Invisalign's Vivera retainers are the gold standard in retention, custom-fitted to your post-treatment teeth. Worn consistently at night, they maintain your perfect alignment indefinitely. Retainer care instructions are provided at your final appointment.
Invisalign is the world's most clinically studied and proven clear aligner system with over 20 years of research and more than 14 million patients treated globally. The proprietary SmartTrack® material provides more precise and predictable tooth movement than generic aligner alternatives. Choosing Invisalign through a certified provider like Sahana ensures you receive the full benefit of the technology and clinical expertise.
