Which is NOT an advantage of a flexible complete denture compared to a conventional one?
Show answer and explanation
Correct answer: C. Lower cost
- A. Less rigidity / flexibility IS an advantage of flexible dentures — they can flex to adapt to tissue changes and are more comfortable for some patients. This IS an advantage.
- B. Flexible dentures (thermoplastic nylon) have better esthetics because the gingival-colored base matches soft tissue without visible metal clasps. This IS an advantage.
- C. LOWER COST is NOT an advantage of flexible complete dentures — they are actually MORE EXPENSIVE to fabricate than conventional acrylic dentures. The specialized thermoplastic (e.g., Valplast) materials and fabrication techniques increase cost. This is the answer — it is NOT true that flexible dentures are cheaper.
- D. Reduced or eliminated metal visibility IS an advantage of flexible dentures — no metal clasps are visible, improving esthetics.
