Certified Dental Technician (CDT) Certification – Exam
Coverage (Complete Content Outline)
The CDT certification covers the full scope of dental
laboratory technology practice, focusing on fabrication,
design, materials science, and clinical collaboration. The
exam is competency-based and tests applied knowledge
across multiple specialty disciplines.

1.
A technician receives a full-arch impression with
acceptable overall detail, but the preparation margin on a
key abutment tooth is partially distorted due to slight tray
movement during setting. The dentist requests immediate
crown fabrication due to patient time constraints. What is
the most appropriate professional action?
A. Proceed because partial distortion is acceptable in
urgent cases
B. Modify the margin area on the model using guesswork
C. Request a new impression before proceeding with
fabrication
D. Fabricate crown and adjust margin intraorally later
Answer: C
Rationale: Marginal integrity is critical for crown fit; even
