Clear Aligners (Spark / Invisalign)

Mega Smile at Na Příkopě 15 offers clear-aligner orthodontics with Spark and Invisalign foil aligners, led by MDDr. Nicole Kufelová — a Motol-trained orthodontist who has treated more than 2,000 aligner patients — and MUDr. Ladislav Kocman with 35+ years of orthodontic practice. Treatment starts with diagnostics including two X-ray images, photographs and a digital intraoral scan, from which a personalised plan with a visualised end result is prepared. Three published Spark plan levels (Spark 10, Spark 20, Spark Advanced) cover mild crowding through complex cases, with typical treatment lasting 1–2 years followed by a retention phase with a bonded retainer and night-time retention foils.

Clear aligners straighten teeth using a series of removable, near-invisible transparent trays, exchanged every one to two weeks, each moving the teeth a fraction of a millimetre according to a digitally planned sequence. Mega Smile (the orthodontic clinic of LK-Medical at Na Příkopě 15, central Prague) works primarily with the Spark aligner system and also offers Invisalign foil aligners, alongside conventional fixed appliances for cases where aligners are not suitable. **The treatment pathway:** (1) An initial consultation and diagnostic work-up: two X-ray images, clinical photographs and a digital impression taken with a modern intraoral scanner — no impression putty. The orthodontist assesses feasibility, estimated duration and cost. (2) A personalised treatment plan is presented, including a digital preview of how the smile should look at the end and a written, transparent price plan before treatment begins. (3) The active phase: aligners are fitted (with small tooth-coloured attachments where needed) and worn 20–22 hours per day, with check-up visits roughly quarterly; treatment typically takes 1–2 years. (4) Retention: a thin wire retainer is bonded behind the front teeth and night-time retention foils are provided for the first months after treatment to keep the result stable. **Plan levels and pricing:** The clinic publishes complete Spark pricing — rare transparency for aligner treatment. For adults over 22 (self-pay): Spark 10 (up to ~10 aligner steps, minor corrections) 61,000 Kč; Spark 20 (moderate cases) 84,000 Kč; Spark Advanced (comprehensive, unlimited-stage treatment for complex cases) 102,000 Kč, plus quarterly check-ups at 1,990 Kč and attachment removal at 1,250 Kč per jaw. Patients under 22 benefit from a Czech health-insurance contribution: Spark 10 at 51,000 Kč, Spark 20 at 74,000 Kč, Spark Advanced at 87,000 Kč — with all examinations and check-ups included — plus a Spark Junior programme for younger patients (phase I 62,000 Kč). **The clinical team:** MDDr. Nicole Kufelová trained in orthodontics at the 2nd Faculty of Medicine of Charles University and Motol University Hospital and is described by the clinic as an expert in Spark and Invisalign invisible aligners with more than 2,000 satisfied aligner patients; she also handles conventional bracket cases. MUDr. Ladislav Kocman has practised orthodontics exclusively since 1988 and founded his own orthodontic practice in 1989, with previous experience at Esthesia, American Dental and H33 Dental Office. **Why Prague:** Published Czech aligner pricing at 61,000–102,000 Kč (~€2,400–€4,100) compares favourably with typical Western European comprehensive aligner fees, and the clinic's location on Na Příkopě — between Wenceslas Square and Náměstí Republiky — is among the most accessible in the city for visiting patients.
