HD PLUS warranty
Warranty information
Every HD PLUS set comes with a genuine warranty card. The card certifies that the restoration was made from blocks manufactured by Doan Huy Dental Plus and is the basis for accepting warranty requests.
Current warranty period
60months
counted from the card activation date
Applies to cards issued from now on. The period is recorded on each card, so it may differ for cards issued at other times — check it on the card check page.
Genuine card, verified by QR
Scan the QR code or enter the card number "HD" + 7 digits to see the status on the website straight away.
Traceable by lot
Each card is tied to the production lot (LOT) of the blocks, so the origin can be traced back when needed.
Activated when the restoration is placed
The warranty period only starts when the laboratory or clinic activates the card.

Scan the QR on the card

Activate when the restoration is placed
The laboratory or clinic enters its details and the placement date. The warranty period starts on the activation date.

Policy
Warranty policy in detail
HD PLUS card warranty policy
The HD PLUS warranty card confirms that your restoration was fabricated from genuine ceramic blanks manufactured by Doan Huy Dental Plus Co., Ltd. Please consult your treating dentist about proper care of your HD PLUS restoration or when warranty service is needed.
Scope
- Applies to restorations fabricated from genuine HD PLUS blanks with a valid warranty card.
- Warranty focuses on material and fabrication defects confirmed after inspection.
- The warranty period is printed on each card and counts from the card activation date. It can differ between cards issued at different times; please check the details on the card-check page.
Conditions
- The card was activated by the laboratory or clinic when the restoration was placed.
- The card is within its warranty period and has not been revoked.
- The card number (and the QR code on the card) can be provided when submitting a request.
- The restoration has been used and cared for as advised by the treating dentist.
Cases generally outside the warranty
- Damage caused by trauma, impact or accidents.
- Damage caused by biting hard objects or uncontrolled grinding.
- Poor oral hygiene or missed follow-up visits recommended by the dentist.
- Restorations that have been removed, modified or repaired by another party.
- Use outside the indication or incorrect placement procedure.
- Cards that have expired, been revoked, or whose details do not match the restoration.
The final decision is made after inspecting the actual restoration and the card record.
How to submit a warranty request
- Check the card — scan the QR code or enter the card number to see its status.
- Submit a request — for a card under warranty, submit directly on the result page (the QR code on the card is required) or call the hotline so staff can create it for you.
- Receipt and response — Doan Huy aims to give a first response within 48 hours of receipt.
- Inspection — you may be asked to send the restoration or photographs for assessment.
- Outcome — depending on the inspection: remake, repair, refund, or no action if an exclusion applies.
How to check a card
Scan the QR code on the card or open the warranty-check page and enter the card number (for example HD followed by 7 digits). The page tells you whether the card is genuine and not yet activated, under warranty, expired or revoked.
If a card number is looked up unusually often, the system shows a notice and asks you to call the hotline for verification — this is only a prompt for further checks, not a conclusion about the origin of the product.
Privacy
The public page shows only minimal card information. Clinic, dentist and tooth-position details appear only when you open the card with the exact QR code printed on the physical card. We never publicly display patient identifiers.

Frequently asked questions
Is a card that is not activated a suspicious card?
No. A card that is not activated has been issued with the set and is not tied to a restoration yet — this is the normal state before the restoration is placed for a patient. The check page shows “Genuine — not activated”.
Who activates the card?
Usually the laboratory or clinic when placing the restoration, since the unit’s details and the placement date are needed. Whoever activates needs the card in hand to scan its exact QR code; typing the card number alone is not enough.
Why do I see the notice “this number has been looked up many times”?
The system records how often and from where each number is looked up in order to detect copied codes. When a number is checked unusually often, the page asks you to call the hotline for verification. It is only a prompt for further checks, not a conclusion about the origin of the product.
What if the QR code is scratched or will not scan?
You can still enter the card number (HD + 7 digits) to see basic information. Activating the card or submitting a warranty request needs the QR code on the card; if the QR is damaged, call the hotline and staff will help.
Do I need to enter the patient’s name?
No. The patient reference is optional and should be only a code or initials of your own choosing. This information is never shown publicly.
What should I have ready when I submit a warranty request?
The card number, a description of the problem and your contact details. Staff will explain if photographs are needed or if the restoration has to be returned for inspection.
