Prometric Exam for Dental Lab Technicians: Dental Laboratory Technician and Aide Licence for DHA, MOHAP, DOH, SCFHS & QCHP — the 11-Area Blueprint, 55% and 50% Pass Marks, CAD-CAM Skills and Salaries (2026)
Every crown, denture and aligner fitted in a Gulf clinic comes from a licensed dental laboratory. This guide covers the Dental Lab Technician paper (150 questions, 55% to pass) and the Dental Lab Aide paper (50%), the eleven official blueprint areas, the materials and occlusion questions that repeat, why CAD-CAM experience decides the job offer, and what technicians earn.
The Gulf has one of the densest private dental markets in the world, and cosmetic work — veneers, zirconia crowns, implant bridges — drives it. All of that is made in dental laboratories, which are licensed facilities whose technical staff must hold a professional licence. Skilled ceramists and CAD-CAM technicians are recruited continuously.
Two papers
| Exam (code) | Questions | Time | Pass mark | Correct answers needed |
|---|---|---|---|---|
| Dental Lab Technician (DLT5521) | 150 | 3 h | 55% | 83 |
| Dental Lab Aide (DLT5522) | 150 | 3 h | 50% | 75 |

Technician or aide?
- Diploma or degree in dental technology (two years or more) → Dental Lab Technician: designs and fabricates independently.
- Shorter certificate, or on-the-job training with documented experience → Dental Lab Aide: model work, investing, finishing and polishing under a technician's supervision.
Dental assistants and hygienists are different professions with their own papers (dental hygienist and assistant guide). Most authorities ask for about two years of recent experience. Run the eligibility check to confirm your title.
The eleven blueprint areas
- Dental anatomy and occlusion — tooth morphology and numbering systems, eruption dates, cusp relationships, articulators and facebow, occlusal schemes
- Dental materials — gypsum types and setting expansion, waxes, investments, casting alloys, acrylic resins, ceramics including zirconia and lithium disilicate
- Removable complete prosthesis — custom trays, record blocks, tooth setting, balanced occlusion, processing, relining and repair
- Fixed restorations — die preparation, margin design, wax-up, casting, metal-ceramic and all-ceramic crowns, pontic design, soldering
- Removable partial prosthesis — Kennedy classification, surveying, clasp design, major and minor connectors
- Infection control — disinfecting impressions and appliances entering and leaving the laboratory
- Dental implant prosthesis — analogues, abutment types, screw- vs cement-retained restorations, passive fit
- Orthodontic appliances — removable appliances, retainers, wire bending, expansion screws, clear aligners
- Maxillofacial prosthesis — obturators and facial prostheses
- Health and safety — dust extraction, monomer handling, burnout furnace safety
- CAD-CAM restorations — scanning, design, milling and sintering, 3D printing
What repeats
- Gypsum products — five types, their uses and water–powder ratios.
- Casting defects and their causes — porosity, incomplete casting, fins, rough surface.
- Kennedy classification from a described arch.
- Porcelain firing — stages, shrinkage, causes of cracking and bubbles.
- Acrylic processing faults — porosity, crazing, raised bite.
- Tooth identification from morphology.
- Zirconia sintering shrinkage and milling strategy.
- Disinfectant choice for each impression material.
What employers ask for
Laboratories hire on a bench test as much as on a certificate. Bring a portfolio of photographed cases. Proficiency in a major dental CAD platform, experience with intra-oral scan files, milling zirconia and printing models now appears in most advertisements, and ceramists who can layer anterior aesthetics command the top of the scale. Laboratories attached to dental groups offer steadier hours; independent commercial laboratories pay more for speed and output.
Process
- Portal registration and title selection (Sheryan, Mumaris+ or the relevant portal).
- DataFlow verification of the qualification and experience (guide, experience certificate format, fees).
- Eligibility, booking (lead times), exam — Prometric for most authorities, Pearson VUE for DOH.
- Offer and activation under the laboratory's facility licence.
Salaries
Dental Lab Aides in the UAE typically earn AED 3,000–5,000 a month and Technicians AED 5,000–10,000; senior ceramists and CAD-CAM leads earn AED 10,000–18,000, sometimes with production bonuses. Saudi packages run SAR 4,000–9,000 for Technicians, usually with accommodation. Compare in the salary calculator and register in the talent pool.
Six-week plan
- Week 1: dental anatomy and occlusion.
- Week 2: dental materials.
- Week 3: fixed restorations and ceramics.
- Week 4: complete and partial dentures.
- Week 5: implants, orthodontic appliances, maxillofacial prostheses, CAD-CAM, infection control and safety.
- Week 6: two timed mocks from the Dental Lab Technician or Dental Lab Aide question bank.
Frequently asked questions
What is the pass mark for the dental lab technician Prometric exam?
55% for the Dental Lab Technician paper and 50% for the Dental Lab Aide paper. Both have 150 questions in three hours.
Can I work in a dental laboratory in Dubai without a licence?
No. Dental laboratories are licensed facilities and their technical staff must hold a professional licence from the health authority.
Is CAD-CAM part of the exam?
Yes. CAD-CAM restorations is one of the eleven blueprint areas, alongside conventional fixed, removable, implant and orthodontic laboratory work.
Is a dental technician the same as a dental assistant?
No. A dental technician makes prostheses and appliances in a laboratory. A dental assistant works chairside with the dentist and sits a different paper.
