Invisalign — Clear Aligners

About Invisalign — Clear Aligners

Invisalign uses a series of custom-made, clear, removable plastic aligners to gradually move teeth into a straighter position, offering an alternative to traditional metal braces for correcting crowding, spacing, and certain bite irregularities. Treatment begins with digital scans or impressions of the teeth, which are used to generate a 3D treatment plan showing the projected movement of each tooth through a sequence of aligner stages; a new aligner is worn roughly every one to two weeks, each one shifting the teeth slightly closer to their final position. Because the aligners are transparent and removable for eating and cleaning, they are often chosen by adult patients or those wanting a less visible option than fixed braces. Small tooth-colored attachments may be bonded to certain teeth to help aligners grip and apply more precise force where needed. Treatment length varies with the complexity of the case, ranging from several months for minor corrections to well over a year for more involved misalignment, and periodic check-ins are needed to monitor progress and issue new aligner sets. Orthodontic clinics in India commonly use in-house 3D scanning and treatment-planning software to design and monitor Invisalign cases for both local and visiting patients.
