Invisalign Clear Aligners

Klinika GHC Praha offers Invisalign clear aligner orthodontics for patients of all ages seeking a discreet, comfortable alternative to fixed braces. Custom-fabricated removable aligners are worn 20–22 hours per day and swapped every one to two weeks to progressively move teeth into alignment. The nearly invisible appearance and removable nature make Invisalign suitable for adults and teenagers in professional or social environments. GHC Praha offers both standard Invisalign for comprehensive cases (both jaws from 125,000 Kč) and Invisalign Lite for mild-to-moderate crowding or spacing (both jaws from 85,000 Kč, one jaw from 45,000 Kč).

Invisalign is the world's most widely used clear aligner system, using a series of precisely engineered, custom-fabricated thermoplastic trays to move teeth in small increments over the course of several months to a few years depending on case complexity. Unlike fixed braces — which use metal or ceramic brackets bonded to the tooth surface and archwires to apply force — Invisalign aligners are fully removable, allowing normal eating, brushing, and flossing throughout treatment. **Treatment options at GHC Praha:** *Invisalign Standard* (both jaws, from 125,000 Kč): The full Invisalign system for moderate to complex cases involving significant crowding, spacing, rotations, overbite, underbite, or crossbite correction. The standard system uses an unlimited number of aligner stages and includes refinement trays as needed, making it suitable for comprehensive orthodontic correction in adults and older teenagers. *Invisalign Lite* (one jaw from 45,000 Kč; both jaws from 85,000 Kč): A streamlined version limited to up to 14 aligner stages, designed for mild crowding or minor alignment corrections — such as closing small gaps, reducing slight crowding in the front teeth, or improving a previously treated relapsed case. Invisalign Lite is faster and more economical for patients who do not need extensive movement. **The treatment process at GHC Praha:** *Step 1 — Initial consultation (3,200 Kč):* The orthodontist assesses the patient's bite, teeth alignment, jaw relationship, and suitability for clear aligner treatment. Not all cases are suitable for Invisalign — severe skeletal discrepancies, certain bite patterns, or heavily rotated teeth may require fixed appliances. *Step 2 — Diagnostic records (3,300 Kč):* If proceeding, the clinic takes dental impressions or a digital intraoral scan, photographs (intraoral and extraoral), and radiographs (panoramic X-ray and cephalometric lateral skull X-ray). These are submitted to the Invisalign laboratory to generate a 3D digital treatment simulation called ClinCheck. *Step 3 — Treatment plan review (1,700 Kč):* The orthodontist presents the ClinCheck simulation, showing the projected tooth movement from start to finish. The patient approves the plan before aligners are manufactured. *Step 4 — Aligner fabrication:* Invisalign fabricates the full set of custom aligners using SmartTrack thermoplastic material. The set is delivered to the clinic (typically 4–6 weeks after approval). *Step 5 — Active treatment:* Aligners are inserted at the clinic, with small tooth-coloured composite 'attachments' bonded to some teeth to assist complex movements. Patients swap to the next aligner in the sequence every 1–2 weeks and attend check-up appointments every 6–8 weeks. Treatment duration ranges from 3–6 months for Lite cases to 12–24 months for comprehensive cases. *Step 6 — Retention:* After the final aligner, a retainer (removable or bonded) holds the corrected position permanently. Teeth naturally tend to shift back without retention; retainer wear is lifelong. **Advantages of Invisalign:** - Nearly invisible during wear — important for adult professionals and teenagers - Removable for eating, drinking, and oral hygiene — no food restrictions and easier brushing - No brackets or wires to irritate soft tissue - Fewer emergency appointments (no broken brackets) - ClinCheck 3D preview allows patient to see the projected outcome before committing - Clinically effective for mild-to-moderate cases (evidence base of 20+ years of published data) **Who is suitable:** Adults and teenagers with mild to moderate crowding, spacing, or alignment concerns. Patients must be motivated to wear aligners for 20–22 hours per day — compliance is critical, as aligners can be removed and forgotten. **Contraindications:** Severe skeletal discrepancies requiring jaw surgery, heavily impacted teeth, significant bone loss (advanced periodontitis), and patients unwilling to comply with wearing requirements.
