SPARK Clear Aligners

ELEJ DENT offers SPARK clear aligner therapy — a transparent thermoplastic aligner system that straightens teeth without visible metal braces. Each set of aligners is individually manufactured from advanced TruGEN XR material and worn for about two weeks before progressing to the next set in the series. Treatment is planned using digital intraoral scans and CBCT 3D radiographs, and a 3D animation visualisation is presented to show the projected tooth movement before treatment begins. The clinic provides three plan tiers — SPARK 10 (up to 10 aligners for mild cases), SPARK 20 (up to 20 for moderate cases), and SPARK Advance (unlimited aligners for complex cases) — with typical durations of six months to three years.

SPARK is a premium clear aligner system manufactured by Ormco, offering an alternative to Invisalign with several technical distinctions. ELEJ DENT is a SPARK-certified provider, meaning the treating orthodontist has completed SPARK-specific clinical training and the practice meets the system's case-submission and monitoring protocols. **How SPARK clear aligners work:** SPARK aligners are made from TruGEN XR, a proprietary multi-layer thermoplastic material that combines clarity, stiffness, and controlled elasticity. The material maintains its transparency better than conventional aligners over the wear period and is designed to deliver more consistent and predictable force levels across the wear cycle. Each aligner in the series moves teeth by a precisely calculated increment — typically 0.2–0.3 mm — toward the planned final position. Patients wear each aligner for approximately 14 days and should keep them in for at least 22 hours per day, removing only for eating, drinking anything other than water, and brushing teeth. **Treatment process at ELEJ DENT:** *Step 1 — Consultation (600 Kč):* An initial appointment to assess suitability and discuss treatment options. No commitment required at this stage. *Step 2 — Initial examination (500 Kč under 21 / 4,000 Kč for 22+):* Digital intraoral scanning of the full dentition, CBCT 3D radiographic imaging (capturing tooth roots, bone structure, and jaw relationship in three dimensions), and clinical photographs of teeth and face. These records are sent to the SPARK laboratory for digital treatment planning. *Step 3 — Visualisation:* The clinic presents a 3D animated simulation of the planned tooth movement, showing the projected position of each tooth at each aligner stage and the anticipated final result. A cost breakdown and payment schedule are confirmed at this appointment. *Step 4 — First aligner delivery:* The first set of aligners is fitted. Patients return for a check appointment 7–10 days later once they have adjusted to wearing them. *Step 5 — Attachment bonding:* Small composite resin attachments — tooth-coloured dots bonded to specific teeth — are placed. Attachments provide the mechanical grip that allows the aligner to create rotational and vertical movements that flat plastic alone cannot achieve. The active treatment phase begins here. *Step 6 — Progress appointments:* Check appointments approximately every five weeks, at which the orthodontist assesses tooth movement, performs any required interproximal reduction (IPR — gentle abrasion between teeth to create space), and provides the next batch of aligners. *Step 7 — Refinement (if needed):* If tooth movement deviates from the original plan or the final result needs further refinement, new scans are taken and replacement aligners are ordered. This is included within the SPARK Advance plan and assessed case-by-case for the lower tiers. *Step 8 — Retention:* After completing the aligner series, a fixed lingual retainer (wire bonded to the inner surface of the front teeth) and a removable retainer are provided. Retainers are essential — teeth will shift without them regardless of how successful the aligner treatment was. **SPARK plan tiers:** - *SPARK 10:* For mild crowding, spacing, or minor bite correction requiring up to 10 aligner sets. Shortest treatment duration (typically 6–10 months). - *SPARK 20:* For moderate cases requiring up to 20 sets. Suitable for moderate crowding, spacing, and Class I bite issues (typically 10–18 months). - *SPARK Advance:* For complex cases — significant crowding, spacing, Class II/III correction, or cases requiring 20+ aligners and multiple refinement rounds. No limit on aligners within the treatment plan price (typically 18–36 months). **Who is suitable:** - Adults and teens with mild to moderate crowding, spacing, or bite issues - Patients who want a discreet orthodontic solution - Patients who cannot wear fixed braces for professional or lifestyle reasons - Patients who want the ability to remove their appliance for sport, performance, or eating **Who may not be suitable:** - Very young children (primary dentition) - Patients with severe skeletal Class III malocclusion (may require surgery in addition) - Patients unable to commit to 22+ hours per day wear time
