Invisalign Clear Aligner Treatment

Sorriso dental in Brno offers Invisalign clear aligner orthodontic treatment led by MUDr. Vladimír Filipi, Ph.D., a board-certified orthodontics specialist. Invisalign uses a series of custom-made transparent removable trays — changed every 14 days — to progressively move teeth into alignment. At Sorriso dental the treatment follows the full clinical protocol: consultation and records, digital ClinCheck simulation (reviewed with the patient before commitment), manufacturing at the Align Technology laboratory, attachment placement, and ongoing check-ups every two months. Treatment typically involves 25–30 aligners. Retention is provided with a fixed lingual retainer and a custom removable night retainer.

Invisalign is the globally dominant clear aligner system, used by over 14 million patients worldwide. Unlike fixed metal braces, Invisalign aligners are removable — taken out for eating, drinking anything other than water, and for brushing and flossing — making them the preferred orthodontic solution for adults and older teenagers who want effective treatment without visible metal. At Sorriso dental, the entire workflow is managed by MUDr. Vladimír Filipi, Ph.D., a specialist in orthodontics, ensuring clinical oversight at every stage. **How the treatment works at Sorriso dental:** *Step 1 — Initial consultation and records:* The orthodontist takes a full set of orthodontic records: photographic series (front, side, intra-oral), study model impressions, and dental X-rays (panoramic and lateral cephalogram). These establish the baseline from which treatment is planned. *Step 2 — ClinCheck digital treatment planning:* The impressions are sent to Align Technology's laboratory (USA). The digital technicians create a ClinCheck — a detailed computer simulation showing each tooth's planned movement across every stage of the aligner series. This is reviewed with the patient; multiple modifications can be requested before the final plan is approved. The patient sees the expected final result before any aligners are manufactured. *Step 3 — Manufacturing:* Once the ClinCheck is approved, the full series of aligners is manufactured (takes approximately five weeks). Each aligner is custom-fabricated in SmartTrack material — a proprietary thermoplastic designed for precise force delivery, comfort, and transparency. *Step 4 — Attachments and interproximal reduction:* Small tooth-coloured composite 'buttons' (attachments) are bonded to specific teeth to provide the leverage points the aligner needs to execute complex tooth movements — rotations, torque control, vertical movements. Interproximal reduction (IPR/stripping) is performed where needed using specialised diamond-coated strips to create the small amounts of space required for tooth alignment without extractions. These are routine parts of the Invisalign protocol at this level of complexity. *Step 5 — Active treatment:* The patient wears each aligner for 14 days, for a minimum of 22 hours per day. Aligners are removed only for meals, drinks (other than water), and oral hygiene. Check-ups at the clinic occur approximately every two months — significantly fewer appointments than fixed braces, which typically require monthly adjustments. Elastics (attached via small hooks on specific aligners) may be added mid-treatment for correcting bite discrepancies. *Step 6 — Retention:* Once the final aligner is worn, a thin fixed wire retainer is bonded to the tongue-side surface of the upper and lower front teeth — permanently preserving the alignment result. A custom removable retainer (similar in appearance to a clear aligner) is worn nightly as a backup. Retention is essential: teeth have a natural tendency to drift back toward their original position, and permanent retainers prevent this without patient compliance effort. **Is Invisalign suitable for your case?** Invisalign is highly effective for mild to moderate crowding, spacing, overbite, underbite, and crossbite. It is not suitable for severe crowding cases where tooth extractions would be required, or for complex skeletal discrepancies requiring surgical intervention. The ClinCheck simulation provides a reliable preview of achievable outcomes; the orthodontist will advise at consultation whether Invisalign is the right treatment for your specific malocclusion. **Advantages over fixed braces:** - Virtually invisible in daily life and in photographs - Removable for eating — no dietary restrictions - Easier oral hygiene — brush and floss normally without navigating around brackets and wires - Fewer appointments (every ~2 months vs monthly) - Smooth plastic surface — no bracket irritation on cheeks and tongue - Digital preview of the result before committing to treatment
