Change History
| Date | Change |
|---|---|
| 2026-08-25 | License verification 2026-08-25 against ONCD annuaire: Dr Umberto Russo found, RPPS 10102084729, Liberal, registered at Sana Oris's Marais (75004) location rather than the on-file Roosevelt (75008) address -- consistent with Sana Oris operating multiple Paris sites. FINESS not searchable (SPA requires browser session, unavailable this session); ZAGA Center itself is a referral network with no separate French establishment registration. |
| 2026-08-25 | Recorded sedation / general anaesthesia availability (informational): documented as available. General anaesthesia offered via partnership for complex/implant (zygomatic/full-arch) surgery; not performed on-site for routine wisdom-tooth extraction |
| 2026-08-25 | Re-verification 2026-08-25: smile24h.com confirms it is a network/platform, not a single clinic ('Smile24h is not a clinic. We are a global network of dental professionals'); ZAGA Center Paris operates through the Sana Oris clinic group, confirmed via Sana Oris's own Instagram post ('ZAGA CENTER PARIS ... Certified Center of Zygomatic Excellence 2026') and LinkedIn. Replaced the vague on-file address with the Sana Oris Paris 8 flagship location (53 Av. Franklin Delano Roosevelt, 75008 Paris) and captured its phone. Captured Google rating 4.6 (817 reviews), geo coordinates and Maps URL for this location. Sedation research: Sana Oris's site FAQ states general anaesthesia is offered, via partnership, for complex/implant surgery (the zygomatic/full-arch work ZAGA Center specializes in), though not performed on-site for routine wisdom-tooth extraction. |
