Invisalign & Spark Clear Aligners

VELKÁ ortodoncie in Ostrava offers both Invisalign and Spark clear aligner systems, prescribed and managed by orthodontic specialist MUDr. Barbora Velká, MBA. Each patient receives a custom-planned series of transparent aligners fabricated to gradually move teeth into the desired position. Aligners are worn 20–22 hours per day and changed approximately every two weeks, with fewer in-office visits required compared to fixed braces. Invisalign patients can use the Virtual Care remote monitoring system — photographing teeth with the Invisalign Lens and My Invisalign app so the orthodontist tracks progress digitally. Spark aligners, offered since May 2021, use a different material composition and may be recommended based on individual clinical needs. Both systems are removable for meals and oral hygiene and contain no metal parts.

Clear aligner orthodontics represents the modern approach to straightening teeth without the aesthetic and lifestyle constraints of traditional metal braces. VELKÁ ortodoncie offers two leading clear aligner systems — Invisalign and Spark — allowing the orthodontist to match the system to each patient's clinical situation, preferences, and treatment goals. **Invisalign** is the world's most widely used clear aligner system, manufactured by Align Technology. Each Invisalign case begins with a digital scan of the patient's teeth (no messy impressions), which is used to generate a precise 3D treatment plan showing the projected movement of every tooth across the entire treatment. The plan is reviewed and adjusted by the orthodontist before production. Invisalign aligners are made from SmartTrack material — a multi-layer polyurethane resin engineered for controlled force delivery and consistent fit. VELKÁ ortodoncie offers the Invisalign Virtual Care remote monitoring programme: patients receive an Invisalign Lens device at the clinic and use the My Invisalign app to photograph their teeth at home according to the orthodontist's schedule. The orthodontist reviews the scans remotely, tracks tooth movement against the treatment plan, and can approve the next set of aligners without requiring an in-person appointment. This significantly reduces the total number of clinic visits needed during treatment. **Spark** aligners were developed by Ormco (a Danaher company) using TruGEN material — a proprietary thermoplastic formulated to be clearer, stiffer, and more stain-resistant than conventional aligner materials. VELKÁ ortodoncie has offered Spark since May 2021. The choice between Invisalign and Spark is made at the initial consultation based on the complexity of the case and the properties of each material system that best suit the clinical requirements. **Treatment process at VELKÁ ortodoncie:** 1. Initial consultation — orthodontist assesses suitability for clear aligners, discusses goals and system options 2. Digital records — intraoral scans, photographs, X-rays if required 3. Treatment plan — 3D digital planning shows projected outcome; patient approves 4. Aligner fabrication — custom series produced in the laboratory 5. Aligner fitting — first set delivered with instructions; Invisalign Lens provided if Virtual Care is used 6. Active treatment — patient changes aligners approximately every 2 weeks (20–22 hours per day) 7. Monitoring — remote via Virtual Care (Invisalign) or in-person check-ups 8. Retention — clear retainers after active treatment to maintain the result **Advantages over fixed braces:** - Virtually invisible during wear - Removable for eating — no food restrictions - Easier tooth brushing and flossing — normal oral hygiene maintained - No metal wires or brackets — no risk of mouth sores from hardware - Comfortable smooth plastic — suitable for contact sports - Fewer in-office appointments, especially with Virtual Care monitoring - Predictable digital planning allows the patient to see the expected outcome before treatment begins **Suitability:** Clear aligners treat a wide range of cases including crowding, spacing, overbite, underbite, crossbite, and open bite. Severe skeletal discrepancies may require a combination of aligners and surgical orthodontics. The initial consultation determines whether clear aligners are the optimal approach. **Financing:** Interest-free monthly installments through Essox are available from November 2025, making the full treatment cost manageable without a lump-sum payment. Contact the clinic for current installment terms. **Preparation for the first consultation:** No special preparation required. Bring any previous orthodontic records (X-rays, study models) if available. The consultation is typically 30–60 minutes.
