Prosthodontics & Occlusion · single question
A patient presents with a complete denture and asks about the strength comparison between denture teeth and natural teeth. How is the strength of complete denture teeth compared to natural teeth?
Show answer and explanation
Correct answer: C. Five times weaker
Complete denture (acrylic) teeth are approximately five times weaker than natural teeth. This is clinically important when explaining to patients why denture teeth wear faster, why they should avoid hard foods, and why regular replacement of dentures (typically every 5–7 years) is recommended as the teeth wear down.
- A. ❌ Ten times weaker overestimates the difference.
- B. ❌ Two times weaker underestimates the difference — denture acrylic teeth are significantly weaker.
- C. ✅ CORRECT – Complete denture acrylic teeth are approximately 5 times weaker than natural dentition.
- D. ❌ Denture teeth are not equal in strength to natural teeth.
