Why it matters for dental
Restorative dentists and lab technicians choosing monolithic zirconia may see shade mismatches that vary with clinic lighting, affecting chairside esthetic outcomes and case acceptance.
Key points
- Study isolates illumination-dependent metamerism as the root cause of perceived shade shifts in monolithic zirconia.
- Findings apply to any practice using multiple light sources (operatory LEDs, natural daylight, laboratory units) for shade selection or final inspection.
- Results are relevant to single-unit anterior crowns where patients and clinicians evaluate shade under differing lighting conditions.
- No specific effective date or regulatory change; the data provide evidence-based guidance for material selection and shade protocols.
