Test Your Knowledge
1.
True or False: PFM (Porcelain-fused-to-metal)
crowns offer the best cosmetic results of any type of dental crown.
2.
True or False: Bruxism (teeth grinding) can
damage teeth so that they need dental crowns.
3.
True or False: PFM crowns offer superior
strength to all-porcelain crowns.
Check Your Answers
1.
False.
All-porcelain crowns offer superior cosmetic results to PFM crowns because PFM
crowns are made up of an under layer of metal to which is attached an outer
layer of porcelain. While the outer layer of porcelain does add a nice cosmetic
touch, the under layer of metal does not allow PFM crowns to achieve the same
level of translucence exhibited by teeth and all-porcelain crowns. The under
layer may also become exposed over time, resulting in a black line at the base
of the crown.
2.
True.
Bruxism subjects teeth to powerful forces and can wear them down over time. Initially,
teeth may lose only enamel. However, enamel loss can weaken teeth, making
structural damage more likely. Should teeth suffer structural damage in the
form of a crack, chip, or break, a dental crown is necessary to repair the
damage and restore the function of the tooth or teeth.
3.
True.
The metal under layer of a PFM crown lends it superior strength. Because PFM
crowns are stronger than all-metal crowns, they are often used in the back of the
mouth, where the forces of biting and chewing are greater and teeth are less
visible.
