SPARK Clear Aligners — Adults

SPARK clear aligners at Elej Dent offer adult patients in Hradec Králové a fully digital, removable orthodontic treatment using the premium American-made SPARK aligner system. Three tiers — SPARK 10, SPARK 20, and SPARK Advance — address mild through complex cases. Treatment begins with a 3D intraoral scan and animated preview of projected tooth movements, and proceeds through scheduled check-ups at approximately five-week intervals until the desired result is achieved.

Elej Dent in Hradec Králové provides adult clear aligner treatment using the SPARK system — a premium transparent aligner brand manufactured from TruGEN crystal-clear thermoplastic material, known for its clarity, stiffness, and attachment precision compared to older aligner materials. **SPARK system tiers:** - *SPARK 10:* Up to 10 aligner steps — suited to mild crowding, spacing, or minor rotations. - *SPARK 20:* Up to 20 aligner steps — moderate cases including broader arch corrections. - *SPARK Advance:* Unlimited refinements — complex adult cases with significant crowding, deep bites, or crossbites requiring extended treatment. **Digital treatment workflow:** Every case starts with a 3D intraoral scan (no impressions), clinical photographs, and a digital bite registration. The orthodontist designs the tooth movement sequence in SPARK's ClinCheck-equivalent software, generating an animated preview of the projected outcome. The patient reviews and approves the virtual result before any aligner is manufactured, ensuring alignment of expectations. **Attachments:** Small tooth-coloured composite bumps bonded to specific teeth at the start of active treatment allow the aligners to exert rotational and vertical forces that removable foils alone cannot achieve. Attachments are invisible in normal conversation and removed at the end of treatment without damage to enamel. **Wearing protocol:** Aligners must be worn 20–22 hours per day, removed only for eating and tooth brushing. Each aligner set typically covers 1–2 weeks of tooth movement before progressing to the next in the sequence. **Check-ups:** Scheduled at approximately five-week intervals throughout treatment. The orthodontist assesses tooth movement tracking, adjusts the protocol if teeth are not following the planned trajectory (refinements), and delivers the next batch of aligners. **Retention:** After active correction, permanent retention prevents relapse. Elej Dent offers both a fixed lingual retainer (thin wire bonded behind the front teeth) and a clear retaining aligner worn nightly. Both are available at treatment completion. **Advantages for adults:** Removable design means no dietary restrictions and normal oral hygiene throughout treatment. Near-invisible appearance makes the treatment suitable for professional environments. SPARK material is stiffer than standard clear aligner materials — clinically shown to deliver more predictable tooth movements with fewer refinements. **Typical treatment duration:** 12–24 months for most adult cases; simpler cases with SPARK 10 may complete in 6–12 months. Complex cases using SPARK Advance may extend to 2–3 years.
