Porcelain denture teeth________________?
Correct answer: C. Have a higher abrasion resistance than gold
- A. Have a higher coefficient of thermal expansion than acrylic teeth:
- B. Have a lower abrasion resistance than enamel
- C. Have a higher abrasion resistance than gold
- D. Should be used where the inter dental clearance is small
Explanation
Porcelain denture teeth are very hard and highly abrasion resistant, even more so than gold, although this hardness can abrade opposing teeth. They require adequate clearance and do not have a higher thermal expansion than acrylic teeth.
