Built by a practising orthodontist. Early access.

Named after enamel's growth lines.

The striae of Retzius record how a tooth grew, layer by layer.

Retzia is a coined name. It keeps your clinic's record the same way.

Every desk, one chart.

PCs and phones share it over your clinic Wi-Fi. No internet needed.

  • Reception, every doctor and a phone at the chair, on one record.
  • Android staff app. iPhones use the browser, after a one-time certificate.
  • A dropped internet connection doesn't stop the clinic.

One chart, built from visits.

Scroll, and watch one sample chart change. Sample data

Every tooth keeps a record.

Thirty-two teeth, drawn in the clinic's own tooth shapes.

Found, then planned.

Tag what you see, then plan each tooth in its treatment's colour.

  • RCT
  • Restorative
  • Paediatric
  • Perio

Done means recorded.

A tooth turns solid only when a dated visit records the work.

Visit records Sample data

    Crowns, bridges and labs, linked.

    The impression opens the lab job. Cementation closes it.

      Children's charts grow up.

      Diagnosis, already filled.

      The prescription fills its diagnosis from what was found and planned.

      Questions, answered briefly.

      Short answers to common questions.

      How do other devices connect?

      Other PCs and phones on the clinic Wi-Fi open it in a browser, over a secure connection using the clinic's own certificate.

      What if the internet drops?

      The main PC keeps working. Other devices need the clinic's Wi-Fi.

      What does the Local Connector see?

      Totals and counts only, never names, phone numbers or notes. It can only read. It signs in with a doctor account, so keep that password private.

      Does Retzia send WhatsApp messages itself?

      No. It opens WhatsApp with the message ready, in the patient's language. Your staff press Send.

      Does it diagnose or suggest treatment?

      No. It records what you enter and shows what happened. Clinical decisions stay with you.

      Which specialties does it cover?

      RCT, restorative with crowns and bridges, orthodontics, implants, periodontics, paediatric dentistry and oral surgery, all on one visit screen.
