Which of the following is NOT an advantage of a flexible (thermoplastic) complete denture compared to a conventional acrylic denture?
Show answer and explanation
Correct answer: C. Lower cost
✓ C) Low cost is NOT an advantage — it is actually MORE expensive.
Flexible/thermoplastic dentures (e.g., Valplast, flexible nylon) advantages include: better esthetics (translucent, tooth-colored clasps), less rigidity/comfort, metal-free. Disadvantages include: HIGHER cost than conventional acrylic, difficulty in repair/relining/rebasing, less rigidity (can actually be a disadvantage as it doesn't distribute forces as well), and potential dimensional changes over time.
