Intraoral scanners capture a digital impression primarily using:
Show answer and explanation
Correct answer: A. Optical (structured light / confocal) imaging
- A. Correct. Intraoral scanners use optical methods (structured-light projection or confocal/triangulation laser imaging) to capture surface geometry and build a 3D digital model.
- B. PVS is a conventional elastomeric impression material, not how a scanner works.
- C. Reversible hydrocolloid (agar) is a conventional impression material.
- D. Intraoral optical scanners do not use ionizing radiation (that is CBCT).
Note: Source stem was unclear; reconstructed to test the operating principle of intraoral scanning.
