Update, September 2026: this article was originally published when Khai Nguyen first received ISO 13485:2016 certification in January 2024. The certificate has since been reissued by ISOCERT on 11 March 2025 to Khai Nguyen Dental Lab Co., Ltd with an expanded scope; the current issue, dated 6 April 2026, is valid until 10 March 2028. Full details, the scanned PDF and how to verify it are on our ISO 13485:2016 certificate page.

First certification, January 2024

On 11 January 2024, ISOCERT (International Certification and Inspection Joint Stock Company) issued certificate no. 9199293420717-MED to Khai Nguyen Lab, confirming that the laboratory’s medical device quality management system conforms to ISO 13485:2016, with a scope of “manufacture and trading of all-ceramic teeth and guide splints” (decision no. 110124.11/QĐ-ISOCERT).

What ISO 13485 means

ISO 13485 is the international standard for quality management systems specific to the design and manufacture of medical devices. A dental restoration made to a clinician’s prescription is a custom-made medical device, so the standard applies directly to a dental laboratory.

Holding the certificate means the laboratory’s processes — case intake, design, production, inspection and delivery — are documented, that named individuals are accountable for each, that materials are traceable by batch, and that every piece of clinician feedback is recorded, analysed for root cause and corrected.

Certification timeline 2024 to 2026

Certificate number 9199293420717-MED has been retained across all issues. Validity can be checked on the ISOCERT verification page using reference 9199293420717, or from the scan on our certificate page.

Why an expanded scope matters to a referring clinic

The 2025 recertification widened the scope from two product categories to six. For a clinic sending work from abroad, scope is the practical part of the certificate: it states which categories of restoration are covered by the audited quality system. A certificate whose scope does not name the product you are ordering does not cover that product.

Our thanks go to the whole Khai Nguyen team, whose daily work produced this result, and to the clinicians, clinics and partners who have placed their trust in us. Certification is a starting point, not a destination.

Since 2023 Khai Nguyen Dental Lab has run a continuing programme called “Alongside the Dentist” and Khai Nguyen Academy: hands-on courses and workshops that let clinicians see how the work inside a laboratory is actually done. This article covers two representative programmes and what participants take away from each.

A 12-hour course as a dental technician

The course is for clinicians who want to carry out every stage of fabricating an all-ceramic restoration themselves rather than hear it described. It runs over five sessions of two and a half hours each, limited to twelve participants so that everyone has their own bench.

Content: the complete all-ceramic fabrication workflow, a materials overview, the basics of CAD/CAM, and — the main part — hands-on waxing, CAD/CAM design, pressing, framework adjustment, ceramic layering and grinding, staining and glaze firing.

What participants take home: two layered veneers, one lithium disilicate onlay and one monolithic multilayer zirconia crown, all made by their own hands.

The real value is not those four restorations. It is that after layering ceramic once, a clinician understands why the laboratory asks for 0.8 mm rather than 0.5 mm on the facial surface, why a shade photograph with a tab in frame matters, and why a case on a dark preparation takes longer. That understanding is the foundation of better clinic–laboratory collaboration.

Workshop: polishing ceramic restorations chairside

“Which polishing bur should I use before and after cementing a ceramic restoration?” is the question we receive most often from clinicians, so the laboratory dedicated a workshop to it on 12 July 2023, limited to eighteen participants. It was led by technician Nguyen Van Hoi, founder of Khai Nguyen Dental Lab, together with Dr Tran Thi Ngoc Trang, co-founder of Nikkori Dental.

Above: the chairside ceramic polishing workshop, 12 July 2023, in partnership with Shofu and Sota-D.

Content: principles of chairside ceramic polishing, the sites that require polishing, bur recommendations for both intraoral and extraoral use, and separate protocols for each restoration type: restorations prepared with the BOPT vertical technique, veneers, onlays, inlays, crowns and bridges, and ovate pontics. The hands-on element was polishing a three-unit zirconia bridge.

What participants take home: a set of thirteen genuine Shofu polishing burs — six straight handpiece and seven contra-angle — a Universal Diamond polishing paste, a bur holder, and the three-unit zirconia bridge used for practice.

Why this subject matters: a ceramic restoration that is occlusally adjusted and not repolished leaves a rough surface that stains and abrades the opposing dentition. The same point is made from the laboratory side in preparation for crowns and veneers.

From early 2025 to early 2026 Khai Nguyen Dental Lab ran and took part in a series of internal training activities, professional exchanges with clinicians, and observation visits by dental students. This article collects them in chronological order, as part of the laboratory’s position that craftsmanship is the core determinant of restoration quality.

February 2025: internal workshop on layering anterior effects, Matisse method

On 22 and 23 February 2025, specialist Ziyang Ke worked directly with our technicians on layering effects that reproduce a natural central incisor using the Matisse method. The outcome was fifteen finished anterior units in which shade, translucency and light reflection were reconstructed from natural teeth. We are grateful to the clinicians who allowed delivery dates to be moved so that our technicians could attend the full course.

March 2025: private workshop with Shofu

A private workshop at the laboratory with Shofu (SotaD) and Ms Connie Moy covered two subjects: building pink gingiva with Ceramage composite, and getting the most out of the Shofu Vintage Prime pressed ceramic system. The hands-on Ceramage gingival work shortened the fabrication time for artificial gingiva on full-arch implant cases while maintaining the esthetic standard.

October 2025: professional session on intraoral photogrammetry at Vien Dong Dental

Khai Nguyen attended a discussion with the clinicians of Vien Dong Dental on “Intraoral photogrammetry (IPG): a new step in the digital full-arch implant impression workflow”. This is the workflow the laboratory applies to full-arch bar cases; it removes the conventional impression step and shortens the time needed to verify implant positions.

November 2025: hosting two groups of resident dentists

Khai Nguyen hosted two groups of resident dentists from the Faculty of Odonto-Stomatology at Van Lang University and the University of Medicine and Pharmacy in Ho Chi Minh City. Our team presented an overview of materials and current restoration types, the production workflow and turnaround times, guided a tour of the production area, and closed with a question and answer session.

November 2025: internal workshop on implant restorations with Dr Nguyen Ngoc Trung Hau

On 21 November 2025, Dr Nguyen Ngoc Trung Hau (Vien Dong Dental) spoke to our technicians about types of implant restoration, material selection criteria and emergence profile design. Within the same programme, Mr Nguyen Tran Nguyen Khai presented on long-term provisional materials for digital All-on-X. A clinical perspective from the dentist helps the laboratory understand why each instruction on a prescription matters.

January 2026: professional exchange with Dr Colin Sar on the Kois Scan Body

Dr Colin Sar visited the laboratory to discuss “Applying the Kois Scan Body to the smile design workflow”. The session gave our technicians access to a more accurate method of merging facial and arch data, so that smile design follows the patient’s facial esthetics more closely.

What this means for the clinics that send us cases

Each activity above maps onto a specific case type: effect layering for single anterior units, pink gingiva for full-arch implants, photogrammetry for implant impressions, emergence profile for implant crowns, and facial data for smile design.

Speakers

• Dr Michael Dieter, Global Head of Education at Ivoclar, an international specialist in direct restorations and preventive dentistry, with many years of teaching at major conferences worldwide.
• Dr Tran Thi Ngoc Trang, co-founder of Nikkori Dental, providing clinical support and interpretation.

Programme

• An update on the esthetics, strength and indications of current all-ceramic systems.
• Optimal preparation design and selection of the luting material for each indication.
• Surface treatment of the restoration to secure a reliable bond.
• Clinical management of complex situations involving all-ceramic restorations.
• Hands-on: direct bonding practice on crowns, onlays and veneers with Ivoclar materials.

Event details

Why this subject matters to a laboratory

Most all-ceramic failures do not originate in the laboratory but at the adhesive interface: insufficient preparation, incorrect ceramic surface treatment, or the wrong cement for the material. When clinician and laboratory share the same understanding of indications, minimum thickness and the bonding protocol for each ceramic system, remake rates fall and restorations last longer. Khai Nguyen is an Ivoclar Lab Partner and uses IPS e.max Press, e.max CAD and ZirCAD Prime in daily production, so co-hosting a workshop on bonding all-ceramic restorations is the most direct way to support the clinicians we work with.

The booth and the two booth talks

Khai Nguyen’s booth at HSDI 2024 was number I9-10. Alongside the product display, the lab held two short talks at the booth, each with its own page giving details and related technical reading:

• Full-arch implant restoration in two appointments, Dr Truong Chi Bao, 10:45–11:30, 14 December 2024.
• Digital impression techniques and restorative material selection, Dr Tran Thi Ngoc Trang, 15:30–16:15, 15 December 2024.

A quiz with prizes ran at the booth throughout: 1–3 correct answers earned a keychain, 4–6 a 20% discount voucher, and 7 a calendar plus a 20% discount voucher.

After the congress

In our recap post of 16 December 2024, we thanked the HSDI organisers for the chance to meet and exchange with many dentists working in implant restoration, thanked the two speakers, and noted the many questions dentists raised after the talks. We also said we hoped to take part in other professional congresses; in early 2026 Khai Nguyen was a Silver Sponsor of the SYD 2026 Congress.

Further reading for dentists

The two subjects presented at HSDI, full-arch implant restoration and digital impressions, are both covered in depth in the lab’s technical articles. Good starting points are intraoral photogrammetry (IPG) for full-arch implants, bar-supported full-arch restorations and which intraoral scanners work with our lab.

Event details

Why Khai Nguyen organises seminars like this

The programme covered what the lab meets every day when cases arrive from clinics: thin veneers that demand conservative preparation, smile design that needs digital facial data, and full-arch implant cases increasingly recorded with photogrammetry instead of conventional impressions. When dentist and lab share one digital language, try-ins and remakes drop noticeably. That is also why Khai Nguyen keeps running training and clinical exchange with dentists alongside operating under an ISO 13485 quality management system.

The organisers thank the attending dentists and the three speakers for presentations with direct clinical application. Dentists interested in photogrammetry workflows for full-arch implants, or in future programmes, can contact us on WhatsApp +84 902 945 585.

Khai Nguyen Dental Lab was a Silver Sponsor of the SYD 2026 Congress, held on 17 and 18 January 2026 at the Windsor Plaza Hotel, 1 Su Van Hanh Street, District 5, Ho Chi Minh City. This year’s theme was “A comprehensive treatment approach in contemporary dentistry”.

Congress details

At the Khai Nguyen booth

The booth showed the restoration lines the lab produces: pressed and feldspathic veneers, multilayer zirconia crowns and bridges, implant restorations from single crowns to bar-supported full arches, with real case samples so dentists could inspect translucency and surface texture directly. Technicians were on hand to discuss material selection and the digital case submission workflow, and the booth ran interactive activities with souvenirs for visiting dentists.

What it means for the lab

For Khai Nguyen, taking part in congresses such as SYD is a chance to hear dentists’ clinical needs and follow new treatment directions, and to adjust production accordingly. It is the lab’s second consecutive year at major industry events, following HSDI 2024.

Dentists who visited the booth and want to send a trial case can contact us on WhatsApp +84 902 945 585 or read the ordering process.

After the congress

In our recap post of 20 January 2026, Khai Nguyen thanked the SYD 2026 organising committee and the dentists and partners who visited the booth over the two days at the Windsor Plaza. We described the congress as a chance for our team to listen, learn and catch up on current approaches to comprehensive dental treatment alongside clinicians, and the booth activities as a way to hand souvenirs to visiting dentists and partners.

Related reading on comprehensive treatment

The congress theme, a comprehensive treatment approach, is close to the cases where clinic–lab coordination matters most: several restoration types in one mouth, with bite and shade to be controlled across all of them. Our technical articles on that kind of work:

• Full-mouth rehabilitation combining veneers, onlays, crowns and implants: occlusion control and shade consistency.
• Case study: full-arch vertical dimension rehabilitation with a digital workflow, with 20 ZirCAD Prime crowns and LiSi overlays.
• Dental ceramic materials comparison: choosing between zirconia, lithium disilicate and feldspathic porcelain.

Two months later, on 7 March 2026, Khai Nguyen co-organised a seminar on comprehensive digital restorative strategy, from veneer esthetics to full-arch implants. Overseas clinics sending a first case can check our special offers; international cases ship by DHL Express, typically 2–4 days in transit.

OFFER: BASIC INVISALIGN COURSE – OCTOBER 2023

A few slots remain with a 20% discount for Khai Nguyen Lab partner dentists joining the basic Invisalign course starting 17 October 2023. This is the last basic Invisalign course of 2023 — dentists interested in enrolling should contact Khai Nguyen Lab quickly to enjoy special offers from both Invisalign and Khai Nguyen Lab.

This offer has ended

This notice was posted on 10 October 2023 and applied only to the basic Invisalign course starting on 17 October 2023. That course has taken place, so the 20% discount described above is no longer available. The page is kept as part of the lab’s activity record; it is not an invitation to enrol.

Background: Khai Nguyen and Invisalign in 2023

The October 2023 offer was part of a programme Khai Nguyen announced at the end of September 2023, when the lab became an official laboratory partner of Invisalign in Vietnam. According to that announcement, the programme included two offers for dentists: 20% off the Invisalign training course fee (about 10 million VND) for dentists referred by Khai Nguyen Lab, and 20% off the service fee for five restorative cases for dentists attending Invisalign training. Both offers belonged to 2023 and do not apply to orders today.

In the same period, Khai Nguyen worked with the Faculty of Odonto-Stomatology at Van Lang University and Invisalign|iTero Vietnam on the conference “Occlusion and Orthodontics in the Digital Era”, held on 30 September 2023.

Esthetic restorations after orthodontics: the lab’s part

The partnership announcement described the lab’s role as post-orthodontic esthetic restorations such as veneers. Once the teeth have been aligned orthodontically, many cases need only minimal preparation, which makes material choice and veneer thickness all the more important. These articles are for dentists planning that stage:

• Minimum veneer thickness: how thin is enough.
• Feldspathic or e.max veneers: how to choose.
• Minimally invasive preparation for crowns and veneers.
• A veneer case with Dr Tony Dental — Veneer and Invisalign Center, a long-standing partner clinic.

For overseas clinics, the offer currently in place is described on our special offers page. For questions about a case, message us on WhatsApp at +84 902 945 585 or email cs@khainguyenlab.vn.
