Lava (PFZ) Crowns
Traditionally, Porcelain
Fused to Metal (PFM) crowns
were developed by porcelain fusing
to a metal substructure. With
further development, all-ceramic
(porcelain) dental crowns were
developed to produce a more natural
appearance. Significant
advancements have since been made,
with Lava dental crowns generating a
considerable buzz in the cosmetic
dentistry industry.
Lava dental crowns
present an innovative computer-aided
design/computer-aided manufacturing
(CAD/CAM) technology to produce an
all-ceramic crown on a zirconia
base. Lava dental crowns were
created by the need for all-ceramic
dental restorations in the posterior
region, which is an increasingly
important aspect of dental care.
Until Lava dental crowns, there were
no real suitable ceramics or
economic processing procedures
available. With the new LAVA
system, it will be possible to
satisfy these demands in the
future.
The Lava system is
based on the machining of
presintered zirconia,
which, due to its outstanding
mechanical properties, its
biocompatibility, and its excellent
esthetics in combination with a
specially designed veneer ceramic,
is the ideal candidate for these
applications. Presintering is
the process of heating of a compact
at a temperature below the normal
final sintering temperature to
increase the ease of handling or
shaping the compact. Zirconia
is a high-tech ceramic material that
is characterized by its outstanding
stability and biocompatibility, as
well as strength levels that are
significantly higher than other
all-ceramic materials. In
addition to strength, Lava
all-ceramic system restorations
display excellent esthetics and
precise fit characteristics.
In combination with a corresponding
CAD/CAM unit, the use of an
easy-to-machine presintered ceramic
material allows for the first time a
reliable, fully-automated and thus,
fast manufacturing of the Lava
Dental Crown.
The advantages of Lava Dental
Crown is summarized:
- Excellent esthetics and
translucency
- Outstanding marginal fit
- Superior strength of
zirconia with high fracture
resistance
- 8 shades of zirconia
framework
- Ideal for 3-unit bridge
applications
- Successful 3-year clinical
trial
The esthetics and
biocompatibility of Lava
restorations represent the optimum
in all-ceramic systems. Many
cosmetic dentists today are shifting
towards the use of Lava Dental
Crowns. They are surprised by
the results - Excellent clinical
margin, fit and stability, and
superior aesthetics.
Preparations require removal of less
tooth structure, and cementation can
be accomplished using proven,
conventional techniques.
If you want a natural and lasting
change to your smile while
optimizing length, rotations and
alignment problems, then Lava
denture crowns can reshape and
whiten your teeth and improve your
smile dramatically.
Captek Crowns:
The
secret to the success of Captek™
is the advanced "Capillary Casting
Technology" used to produce the gold
coping for Captek crowns and
bridges. The unique composite metal
is 88% gold reinforced with small
particles of high fusing and high
strength platinum and palladium,
resulting in a restoration with the
vital and natural look of gold, the
superior strength and durability of
platinum and palladium and the extra
benefit of reducing harmful bacteria
around the gums.
Health
- The advanced gold coping
material is proven to reduce the
accumulation of harmful bacteria
at the gum line by 90% compared
to natural tooth structure.*
Strength
- The infusion of platinum and
palladium into gold produces an
extremely dense and strong
coping.
- Extreme bond strength
between the porcelain and Captek
gold reduces fractures.
Esthetics
- Captek gold does not
oxidize, eliminating the black
or gray margins of traditional
PFMs.
- The warm gold color of
Captek understructure provides
natural light dispersion.
WHY PRESSED CERAMIC?
Pressed ceramic technology
produces consistently precise crowns
by eliminating shrinkage, porosity
and the inconsistency of brush
build-ups.
Defined anatomy with
occlusal accuracy and precise
contacts
- Because there is no porosity
or shrinkage, your case can be
idealized in wax, then
duplicated in pressed ceramics.
No need for porcelain additions,
corrections or repairs.
Shade vitality and consistency
- Pre-blended ingots (70%
dentin shade, 30% enamel
translucency) provide natural
looking depth of translucency
and color.
Increase Strength
- Closed system of continuous
pressure "pressing" eliminates
porosity and impurities,
providing a denser, stronger
crown with a flawless surface.
Surface integrity
- Pressed technology
eliminates porcelain shrinkage
and porosity, making a smoother
and stronger surface that is
less abrasive to opposing
natural dentition.
Remember, your
smile speaks before you even say
a word!
