Crowns
Crowns
can be used to correct color and alignment defects and structural
damage to individual teeth. This process is more invasive than
veneers, but provides a stronger restoration when added strength is
required. Crowns come in 3 basic types: all gold, all porcelain, or
a blend of the two. Gold is the most predictable and requires the
least removal of tooth structure, but may not be the best cosmetic
choice. All porcelain crowns provide the best cosmetics, but
sometimes requires removal of more tooth structure than the other
crowns, and has a higher risk factor for cracking than gold crowns.
PBM's (porcelain bonded to metal crowns) provide an OK cosmetic
result while relying on the predictability of the metal for a tight
seal. PMB's are currently the most common crown choice, but
recent advances in all porcelain crowns are starting to change
that.
Crowns
are most often done one at a time, but in some situations, multiple
teeth are in need of work and can cause significant aesthetic
concerns. If your smile is like the examples shown, crowns can be
used as a quick and very successful way to improve your
smile.
Case #3
- 8 Procera all Porcelain Crowns
This
individual had several PBM style crowns on her top teeth that where
breaking down, some of which showing the characteristic "black
line" that often appears at the gum line with this type of crown.
Rather than doing a couple at a time, the patient opted to
have 8 done at once. This allowed for the best control over the
shape and color the new crowns. Additionally, the patient opted for
Procera all porcelain crowns to improve the aesthetics and help
avoid any future "black lines". The top front 8 teeth were
done with this case over 3 visits.
Case #2 - 4 Procera all
Porcelain Crowns
This individual did not
like the look of her front teeth as they were discolored, chipping,
and heavily worn down. However, she did like the space between her
front teeth and wanted to maintain that. To correct her concerns, 4
Procera crowns were done on the top front 4 teeth.
Case #1 - 8 PBM
Crowns
This individual had
multiple teeth that were breaking down and extensively restored
with various fillings. To improve the cosmetics of these teeth, and
ultimately improve the overall strength of the restorations, 8 PBM
crowns were opted for on the top front teeth. PBM's were chosen
over all porcelain crowns due to the extensive restorations already
present and the need to preserve tooth structure (at the time this
case was done, all porcelain crowns required greater thickness than
PBM's, which is no longer the case).
