How Do Clear Aligners Work? A Complete Guide
By Dr. Maryam Tahir (BDS), Orthodontist at Aligno Lahore
Clear aligners use a series of custom-made, transparent trays to gently move your teeth over time. Each set of aligners applies precise, controlled forces to specific teeth, gradually shifting them into their ideal positions. Learn how the technology works, what the treatment process looks like, and why millions of patients worldwide now prefer aligners over traditional braces.
The Science Behind Clear Aligners
Clear aligners work through a process called controlled force application. Each aligner is designed to move specific teeth by small amounts (typically 0.25-0.3mm per tray). The aligners are made from medical-grade thermoplastic material that fits snugly over your teeth, applying gentle but consistent pressure.
The Treatment Process Step by Step
Your clear aligner journey begins with a comprehensive 3D scan of your teeth. This digital model is used to create a precise treatment plan showing every stage of tooth movement. Your orthodontist reviews and approves the plan before manufacturing begins.
How Long Does Treatment Take?
Most clear aligner treatments take 3 to 7 months, depending on the complexity of your case. Each set of aligners is worn for 1-2 weeks before switching to the next set in the series.
